[0025] Specifically, the bottom end of the guide slider 3 is fixedly connected to a connecting frame 8 with an "L"-shaped structure by screws, and a plurality of cleaning bristles 9 for cleaning the guide pulley body 13 are fixedly connected at equal intervals to the top of the connecting frame 8. By setting the cleaning bristles 9, when the guide pulley body 13 rotates during use, the contact surface of the wire to be guided will be cleaned by the cleaning bristles 9 to avoid impurities sticking to the contact surface of the wire, which may cause damage to the transmitted wire.

[0026] Furthermore, the front end of the guide slider 3 is fixedly connected to a connecting block 10, and a rotating cavity 11 is opened inside the connecting block 10, and a rotating block 12 is movably connected inside the rotating cavity 11, and the front end of the rotating block 12 is fixedly connected to a guide pulley body 13.
