At this time, the threaded rod and the threaded block cooperate with each other to form a vertical path. A threaded block cooperates with a sliding sleeve to complete the installation and fixation between the pressure plate. Therefore, under the design of the opposite external threads of the threaded rod, the two pressure plates can be close to or away from each other. When it is necessary to stabilize, the pressure plate can be close to the connection socket and then clamped up and down. Then the movable groove is opened inside the pressure plate. When the clamping and stabilizing work is performed, the buffer spring is compressed and the adjustment column moves inside the movable groove. In this way, the limit frame and the protective pad can be used to provide a certain contact protection. At the same time, it also has a certain clamping buffer, thereby better improving the overall anti-pull ability during the work process;

[0015] (2) The mounting plate is fixed on both sides of the connector body, and then the mounting hole is opened inside the mounting plate. The mounting hole is used to connect the side wings of the mounting plate. Bolts are used to form a connection installation at the position of the mounting hole, and the gasket is fixed around the mounting hole at the top of the mounting plate. In this way, the gasket plays the purpose of cushioning protection, thereby improving the connection stability during the installation process;

[0016] (3) By opening the heat dissipation hole on one side of the top of the connector body, and the vertical position of the heat dissipation hole is adapted to the servo motor, it can be used for air circulation at the servo motor position. At the same time, a mounting ring is installed at the top of the connector body at the peripheral position of the heat dissipation hole. At this time, the dust net can be used for dust prevention. The connection and installation between the mounting ring and the connector body are completed by screws. When disassembling, the screws can be removed to complete the disassembly of the mounting ring, thereby facilitating subsequent daily maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS
