Full Text	1. Field of the Invention The present invention relates to a mounting type feeding device having multiple feeding wheels symmetrically provided at opposite sides of a frame which has a rear end thereof mounted on an outer side surface of a top cabinet of a narrow fabric loom. 2. Description of Related Art It has become popular for people to carry items such as camera bags or shoulder bags by using a decorative strap that has a manufacturer's or owner's name woven into it. A shuttle loom used to weave decorative straps normally comprise a warp yarns feeding device provided therein. Because the patterns of the straps are designed to be more and more beautiful and complex, a conventional feeding device of the shuttle loom generally consists of multiple feeding wheels in order to satisfy the different requirements of various patterns of straps. As shown in Fig. 3, a conventional feeding device of a narrow fabric loom comprises two parallel frames (90, 92) respectively disposed in upright positions at two opposite sides thereof, a driving shaft (94) extending horizontally between the two frames (90, 92), a feeding assembly (940) including multiple feeding wheels mounted around the driving shaft (94), and a driving gear (96) including multiple gear wheels (962) and a driving belt (960) provided at an outer side of the frame (90). The driving shaft (94) is driven by a motor of the loom via the driving gear (96) to run so as to cause the feeding assembly (940) to run, therefore the yams respectively threaded on the feeding wheels are fed by the feeding assembly (940) for weaving a decorative strap. However, the aforesaid conventional feeding device has some drawbacks in the operation which are as follow. First, to thread yarns on the feeding wheels of the feeding assembly (940), an operator has to move from one side to another side of the loom, because the feeding assembly (94) is disposed in inner sides of the frames (90, 92). Second, if belts, feeding wheels, friction rings or other components of the feeding assembly (940) need to be replaced, the driving shaft (94) must be disassembled from the frames (90, 92), and the driving gear (96) must be disassembled in advance. Then, all these parts have to be reassembled and the driving gear (96) and the feeding assembly (940) must be adjusted again, so the replacement of the conventional feeding device is quite complicated. Third, because the driving gear (96) is exposed at the outer side of the frame (90), when the gear wheels (962) are running at high speed, there is a risk in the operation of threading yarns around the feeding wheels for the operator who must carefully avoid getting caught up in the driving gear (96). Therefore, it is an objective of the invention to provide an improved feeding device of a narrow fabric loom to mitigate and/or obviate the aforementioned problems. SUMMARY OF THE INVENTION The main object of the present invention is to provide a mounting type feeding device of a narrow fabric loom. The mounting type feeding device has a frame mounted on an outer side surface of a top cabinet of the narrow fabric loom and extending in a direction parallel to warps, a driving gear provided at one side of the frame, and a feeding assembly including multiple feeding wheels symmetrically disposed at two opposite sides of the frame, whereby the feeding assembly is driven by a motor via the driving gear to feed yams for weaving of decorative straps. The operation of threading yams on the feeding assembly and replacing of components of the feeding assembly are both easy, and the safe reliability for an operator in the operation of threading yarns around the feeding wheels is improved. Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a mounting type feeding device of a narrow fabric loom in accordance with the invention, showing the feeding device in a view of one angle; Fig. 2 is a perspective view of the mounting type feeding device of the narrow fabric loom in accordance with the invention, showing the feeding device in a view of another angle; and Fig. 3 is an exploded perspective view of a conventional feeding device of a narrow fabric loom. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in Figs. 1 and 2, a mounting type feeding device of a narrow fabric loom comprises a frame (10) mounted at one side of a top cabinet of the narrow fabric loom and extending in a direction parallel to warps, a driving gear (20) provided at one side of the frame (10), and a feeding assembly (30) driven by a motor of the loom via the driving gear (20). The frame (10) has a rear end thereof securely connected with a mounting plate (12), which is mounted on an outer side surface of the top cabinet of the narrow fabric loom. One reinforcement plates (14) is abutted against one of two opposite sides of the rear end of the frame (10). The driving gear (20) is positioned close to a side surface of the frame (10). The feeding assembly (30) includes a driving shaft (32) extending horizontally through the frame (10), and multiple feeding wheels mounted around the driving shaft (32) and symmetrically disposed at two opposite sides of the frame (10). A bracing bar (36) is extended horizontally through the frame (10). Two opposite ends of the bracing bar (36) and the driving shaft (32) are respectively connected by two bracing pieces (360) so as to ensure the stability of the two opposite ends of the driving shaft (32). A lower end of the frame (10) is optionally connected with an extension portion (16) extending in a direction parallel to the warps. A secondary feeding assembly (40) includes a driving shaft (42) extending horizontally through the extension portion (16), and multiple feeding wheels mounted around the driving shaft (42) and symmetrically disposed at two opposite sides of the extension portion (10). The mounting type feeding device of the invention has the following advantages: 1. Because the feeding wheels of the feeding assembly (30) are symmetrically disposed at two opposite sides of the frame (10), an operator can easily thread yams on the feeding wheels without having to move frequently from one side to another side of the loom. 2. All components of the feeding assembly (30) can be easily replaced without disassembly of the frame (10) and driving gear (20). 3. The driving gear (20) is positioned close to one side surface of the frame (10), whereby the operator can easily avoid getting caught up in the driving gear (20), so that the structure of the feeding device has an improved safe reliability in its operation. 4. Because a secondary feeding device (40) is provided on the extension portion (16) connected at the lower end of the frame (10) to provide easy access to the operator, the production efficiency of the narrow fabric loom is improved. It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. WHAT IS CLAIMED IS: 1. A mounting type feeding device of a narrow fabric loom comprising: a frame (10) mounted on an outer side surface of a top cabinet of the narrow fabric loom and extending in a direction parallel to warps; a driving gear (20) provided at one side of the frame (10); a feeding assembly (30) including a driving shaft (32) extending horizontally through the frame (10), and multiple feeding wheels mounted around the driving shaft (32) and disposed symmetrically at two opposite sides of the frame (10); whereby the feeding assembly (30) is driven by a motor via the driving gear (22) to feed yams for weaving of decorative straps. 2.
