[0023] In this embodiment, the adjusting moving mechanism includes a rotating brake motor 2 fixedly installed inside the fixed base 1, and the output shaft of the brake motor 2 is fixedly installed with a reciprocating screw 3 rotatably connected to the fixed base 1. The outer side of the reciprocating screw 3 is threadedly connected to a thread block 4, and a thread groove is provided inside the thread block 4. The thread block 4 is threadedly connected to the reciprocating screw 3 through the thread groove, which facilitates the movement of the thread block 4 on the outside of the reciprocating screw 3.
