[0003] At present, there are various kinds of clamping jaws, and corresponding clamping jaw can be selected according to different fields and scenes, such as pneumatic clamping jaw, electric clamping jaw and hydraulic clamping jaw, but no matter which driving mode is adopted, the jaw body will be clamped or opened under the action of driving force, so as to grasp the object. With the different clamping objects, the jaw body will change accordingly, such as clamping pipe, which needs to open an arc groove in the jaw body, so as to improve the clamping force of the pipe. If different objects need to be clamped, the jaw body needs to be disassembled and reinstalled with the required shape of the jaw body, so as to clamp different objects under the action of the clamping jaw.

[0004] Through the analysis of the prior art, the scheme can meet the clamping of different objects under the condition of disassembling and replacing the jaw body, but there are still some deficiencies. Since the clamping jaw can only clamp specific objects, if another object needs to be clamped, the jaw body of the clamping jaw needs to be disassembled and replaced with a clamping jaw structure that adapts to different objects. Since the structure of the clamping jaw is relatively precise during installation, the stability of object clamping needs to be maintained. If the shape of the object is different, different jaw bodies need to be replaced, which greatly increases the replacement time of the subsequent clamping jaw. At the same time, because the jaw body is disassembled and replaced many times, the precision of the jaw body is easily damaged during installation, which easily causes the object to be clamped to be fluctuated during the clamping process, affecting the accuracy of the clamping jaw placement and picking in the automatic production line.

[0005] Therefore, the present application aims to improve the efficiency of the jaw body adapting to the object and the accuracy of the jaw body clamping the object under the condition of clamping different shape objects. UTILITY MODEL CONTENTS
