A MEASURING INSTRUMENT FOR DETACHING FORCE OF A SNAP MEMBER

Abstract

A constraining device comprises a plurality of jaws 34 adapted to constrain the sides of an object of constraint, support shafts 35 rotatably supporting the respective jaws so as to allow the jaws to spread and become closed, first biasing means 36 adapted to bias the respective jaws to become closed, a jaw opening/closing drive member 62 arranged at the center of the jaws so as to move close to and away from the object of constraint and presS the base end portions of the jaws to drive the jaws when moved in a first direction, a second biasing means 63 adapted to bias the jaw opening/closing drive member in the first direction in order to close the jaws and a temporary holding section 66 arranged at the jaw opening/clo.sing drive member and adapted to be engaged with the base end portions of the jaws to block the jaw opening/closing drive member against moving in the first direction but allow the jaw opening/closing drive member to move in the first direction when force exceeding a predetermined level is applied to the jaw opening/closing drive member in the first direction.
