Fixture

The utility model relates to a clamp which comprises a shell and a driving mechanism contained in the shell. The clamping jaw assembly is partially arranged outside the shell, and the clamping jaw assembly comprises at least two clamping jaws; the driving mechanism can drive the clamping jaw assembly to move, so that the clamping jaw assembly is switched between a first deformation state and a second deformation state; wherein in the first deformation state, the at least two clamping jaws are gathered together, and in the second deformation state, the at least two clamping jaws are separated from each other. 本申请涉及一种夹具，所述夹具包括：壳体，驱动机构，收容于壳体内；夹爪组件，部分地设置于壳体外，夹爪组件包括至少两个夹爪；驱动机构能够带动夹爪组件运动，使得夹爪组件在第一形变状态和第二形变状态之间切换；其中，在第一形变状态时，至少两个夹爪相互聚拢，在第二形变状态时，至少两个夹爪相互分离。
