When the existing sawing machines process shorter workpieces, in order to ensure that the saw blade can cut the workpiece, the fixed clamp / movable clamp only clamps and fixes the rear end of the workpiece. The contact area between the workpiece and the fixed clamp / movable clamp is small, resulting in low clamping stability of the clamp on the workpiece, affecting the processing accuracy of the sawing machine, and even the workpiece may pop out from between the fixed clamp and the movable clamp. Therefore, further improvement is needed. Utility Model Content
