Torque limiting joint

The utility model relates to the technical field of joints, in particular to a moment limiting joint, which is characterized in that a thread is arranged at one end of a joint main body far away from a button cap, a plurality of grooves are arranged at one end of the joint main body far away from the thread, and a force limiting device is arranged on the joint main body. A first rotating groove is formed in the end, close to the connector body, of the button cap, a plurality of shifting blocks are arranged in the first rotating groove, and a plurality of anti-skid lines and a plurality of twisting plates are arranged on the outer surface of the button cap, so that the situation that a connecting piece is damaged due to too large applied force or a pipeline is not connected due to extrusion can be prevented; or fluid leakage is caused due to improper compactness caused by too small force application and the like. 本实用新型涉及接头技术领域，具体的说是一种力矩限制接头，所述接头主体远离钮帽的一端设置有螺纹，所述接头主体远离螺纹的一端设置有若干凹槽，所述接头主体上设置有限力装置，所述钮帽靠近接头主体的一端内部
