[0021] The telescopic rod 304 forms an elastic telescopic structure with the sleeve rod 301 through the sliding block 303 and the first spring 302. The elastic telescopic structure enables the clamping block 305 to have a certain movable effect. The device is provided with multiple clamping blocks 305, and each can operate independently. In this way, during the clamping process, the clamping block 305 will automatically match according to the shape on the surface of the gearbox, so as to clamp the gearbox stably, and there will be no situation where only a point of the gearbox is clamped during clamping, which will cause unstable clamping of the device.

[0022] like Figure 2 and Figure 4 As shown, the moving assembly 2 includes a connecting block 201, a moving rod 202 and a fixing frame 203, and the upper end of the connecting block 201 is connected to the moving rod 202, and the upper end of the moving rod 202 is connected to the fixing frame 203;

[0023] The connecting block 201 facilitates the traction rope 403 to pull the moving rod 202 , and the fixing frame 203 facilitates the installation of the sleeve rod 301 .
