[0021] Among them, there are four splints 3, which are respectively located at the top and bottom of the limiting device body 1, and there are two pins 4, which play a role in ensuring a stable connection between the transmission system and the limiting device body 1, thereby preventing the limiting device body 1 from falling off during use.

[0022] Specifically, by providing an adjustment mechanism, the limiting device body 1 can be adjusted according to the size of the transmission system, so that the limiting device body 1 can be suitable for transmission systems of different sizes, thereby improving the practicality of the anti-friction torque limiting device. By providing a pin 4 and a bolt 5, the purpose of making the connection between the transmission system and the limiting device body 1 tighter is achieved.

[0023] like Figure 1 and Figure 2As shown, in this embodiment, the adjustment mechanism includes an adjustment slot 701 opened inside the limiting device body 1, an extension block 702 with one end penetrating and extending to the outside of the limiting device body 1 is movably installed inside the adjustment slot 701, a fixed block 703 is fixedly installed at the bottom of the extension block 702, a motor 704 for driving is fixedly installed on the left side wall of the inner cavity of the adjustment slot 701, a support rod 705 is fixedly installed on the output shaft of the motor 704 through a coupling, and a first bevel gear 706 is fixedly installed on the right side of the support rod 705, and the adjustment slot 701 A threaded rod 707 is rotatably installed on the inner bottom wall, and a second bevel gear 708 is fixedly installed on the outer surface of the threaded rod 707.
