FAST-SLIDING VISE AND FAST-SLIDING ENGAGING PART

摘要

A fast-sliding vise, comprising: a fixed jaw (01) and a movable jaw (02) which are disposed opposite each other and which may move, and open or close in a front-back direction; a radial stop block (06) is provided on the movable jaw; the radial stop block nests on a neck of a moving rod (03); an end face clutch (07) is further provided on the moving rod, the end face clutch being able to rotate when the moving rod rotates and to slide relative to the moving rod; a rear section of the moving rod is a flat-cam rod (036); the flat-cam rod passes through a toothless groove nut (04); a fast-sliding engaging part, comprising: the moving rod having the flat-cam rod, and the toothless groove nut which corresponds to the flat-cam rod; when a non-circular cam (039) of the flat-cam rod is rotated to fit to groove teeth (042) of the toothless groove nut, the flat-cam rod cannot move axially within the toothless groove nut; when the non-circular cam of the flat-cam rod is rotated to disengage from the groove teeth of the toothless groove nut, the flat-cam rod may slide axially within the toothless groove nut. The fast-sliding vise and the fast-sliding engaging part have a long service life and are easy to manufacture at a low production cost.
