Clamp

The utility model discloses a clamp which comprises a machining plate, a plurality of sets of discharging holes are formed in the upper surface of the machining plate, a clamping assembly is fixedly installed on the upper surface of the machining plate, and two sets of fixing assemblies are symmetrically installed at one end of the clamping assembly in a sliding mode. The sliding plate slides to drive the clamping plates to slide, so that the two clamping plates are matched with each other to be adjusted and fixed according to the length of a machined object, an output shaft of a second positive and negative rotation motor rotates to drive a rotating rod to rotate, the rotating rod drives two gears to rotate, and the gears are meshed with tooth grooves, so that a lifting plate slides up and down; and the lifting plate drives the limiting plate to adjust and fix according to the height of a processed object. 本实用新型公开了一种夹具，包括加工板，加工板的上表面开设有若干组排料孔，加工板的上表面固定安装有夹持组件，夹持组件的一端滑动安装有固定组件，固定组件对称设置有两组。本实用新型通过滑板滑动带动夹持板滑动，使得
