Field of the Invention The present invention relates to an improved structure of knitting machine, particularly to a multi-function machine which is adapted from producing one kind of fabric to producing another kind of fabric such as single knit, plain terry, double knit, single jacquard, double jacquard. 2. Description of the Prior Art The conventional knitting machine can only use a kind of knitting method and produces a single type of fabric such as single knit, double knit, or jacquard. Although the configuration and structure of these machines have only a little bit difference, they can't be replaceable with each other and are not compatible. Thus a knitting factory needs to set various kind of machines with different functions in order to fit the needs of producing different kind of fabrics in order to meet different demands of clients and seasonal change. Due to the fashions and seasons change, the amount and sort of the fabrics always need to adjust by time, each kind of fabrics is not with the same production so that only some kind of machines are running day and night yet some sort of machines are lack of full use. Except the low efficiency of some kind of machines, knitting machines often occupies quite a lot of area for use in the factory. SUMMARY OF THE INVENTION Therefore, it is the primary object of the present invention to provide an improved knitting machine having interchangeable components such as upper and lower cylinder mechanisms, a dust cleaning system, and rings for fixing thread. By the design of the present invention, the components can be converted and replaced simply and conveniently in order to achieve the shift in functions and avoid the waste of cost of machines. According to the above object, the main components of the present invention include mechanical main body, cylinder mechanism, yarn feeders, and fabric winding system. The cylinders are mounted on the top of the base of the main body. The upper and lower cylinder mechanisms are driven by synchronous shafts. The yarn is transmitted from yarn feeders to cylinders and then knitted to clothes and wound by the fabric winding system. The apparatus is characterized in that upper and lower cylinder mechanisms are all interchangeable so that the upper cylinder can be replaced with radial dust cleaning system. In addition, an upper support rack and a set of rings for feeding thread can be mounted on the base. Therefore, the present invention has multi-functions, wherein the upper and lower cylinders can be adjusted or replaced, or added with optional elements such as an upper support rack, rings for feeding thread and radial dust cleaning system in order to convert the model of producing fabric from one to another. The foregoing object and advantages of the present invention will be more apparent from the following detailed description, as taken in conjunction with the accompanying drawings wherein; BRIEF DESCRIPTION OF THE DRAWINGS FIG 1 is the perspective view of the present invention; FIG 2 is the assembling view of the present invention; FIG 3 is the parts location view of the present invention as double knit machine; FIG 4 is the explosive view of the block of the upper block ring and circular seat of the upper cylinder mechanism.
