During the mechanical processing and manufacturing process, the clamp is used to clamp and fix workpieces, so that the workpieces have correct positions and work operations can be carried out.

[0003] According to the search, the patent authorized publication No. CN218746237U discloses a lever clamp. Although the inner thread on the inner wall of the locking nut and the outer thread on the surface of the bolt are closely engaged through the double elastic force of the first spring and the second spring, the workpiece is clamped firmly, and a certain force can be continuously provided to one end of the clamping frame. According to the lever principle, the other end of the clamping frame continuously clamps the workpiece. However, during use, the bolt is manually rotated and threaded with the nut to move downward, lifting one end of the clamping frame, and then manually rotating the locking nut. Single operation can only clamp the workpieces of one group of workstations. The operation mode is relatively complicated and laborious, resulting in a large amount of manual labor and affecting the work operation efficiency of the workpieces. Based on this, the utility model designs a novel lever clamp to solve the above problems. UTILITY MODEL CONTENTS
