[0002] With the continuous development of society and the continuous improvement of science and technology, people are paying more and more attention to the field of mechanical design. Mechanical design is a working process that conceives, analyzes and calculates the working principle, structure, movement mode, force and energy transmission method, material and shape and size of each part, lubrication method, etc. of the machine according to the requirements of use, and converts it into a specific description as a basis for manufacturing.

[0003] The Chinese utility model patent with announcement number CN220094354U discloses a mechanical clamp, which sets a clamping plate and rotates the two groups of second turntables so that the second turntables drive the second screw rod to rotate synchronously, thereby making the two groups of second clamping blocks move inward and clamp both sides of the workpiece, and then the two groups of first turntables are rotated so that the first turntables drive the first screw rod to rotate synchronously, thereby making the two groups of first clamping blocks move inward and cooperate with the clamping plate to clamp the two ends of the workpiece, and finally the four groups of third turntables are rotated so that the third turntables drive the third screw rod to rotate synchronously, thereby making the four groups of third clamping blocks move downward and cooperate with the bottom plate to clamp the upper and lower ends of the workpiece, thereby achieving the purpose of flexibly clamping and fixing workpieces of different types and sizes in different directions, thereby avoiding the situation where the workpiece slips during operation and causes the workpiece to be damaged and cannot be used, and its overall structural design is simple and reasonable, highly practical, and easy to promote and apply.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the device is clamping, the object is clamped by the clamp, but the clamp cannot sense the pressure of the clamp on the machine. Excessive pressure can easily cause local deformation of the machine and affect the quality. It is necessary to stop clamping in time after the clamping is completed to avoid damage to the clamped object. Utility Model Content
