  • Bench vice
    Patent number: 9327386
    Abstract: A bench vice includes a fixed vice body, a movable vice body, a screw rod, a screw nut, a quick-action mechanism, and an operating handle. The quick-action mechanism controls the screw rod and screw nut to engage or disengage so as to move slowly or quickly. The operating handle operates the quick-action mechanism. The movable vice body is assembled with the screw rod into an assembly, and both the quick-action mechanism and the operating handle are arranged on the front end of the fixed vice body. Since the quick-action mechanism and the operating handle are arranged on the front end of the fixed vice body, the operator can operate more conveniently, and thereby the working efficiency is improved.
