[0030] like Figure 2 As shown, this decelerator lever anti-rotation tool includes a control system 2; the mechanical transmission section includes a base plate 7, a synchronous belt 8, a driven synchronous belt pulley 603, a main synchronous belt pulley 901, a stepper motor mounting plate 303, a stepper motor 3, and a guide rail slider mechanism 10, wherein: the synchronous belt 8 is mounted on the base plate 7 in cooperation with the driven synchronous belt pulley 603 and the main synchronous belt pulley 901; the stepper motor 3 is mounted on the base plate 7 through the stepper motor mounting plate 303; the guide rail slider mechanism 10 is mounted on the base plate 7 and located in the middle of the synchronous belt 8; the deceleration brush section has a brush 5 mounted on the guide rail slider mechanism 10 through a brush connecting rod 4.

[0031] like Figure 2 and Figure 4 As shown, the control system 2 is located at the tail end of the reducer tool. The wireless communication board 201, stepper motor driver 202, microcontroller 203 and wireless charging board 204 are attached to the mounting bracket 206. The wireless charging coil 205 is placed at the very end of the base plate 7. The mounting bracket 206 is mounted on the base plate 7 by mounting bracket screws 207. The battery 208 is attached to the base plate 7 and located below the mounting bracket 206.

After brush 5 contacts the target object and completes the anti-rotation operation, stepper motor 3 reverses, and guide rail slider mechanism 10 returns to its original position until it hits limit block 1006 and stops moving. Brush 5 then fully retracts, completing the anti-rotation operation.
