[0031] Specifically, by starting the bidirectional electric telescopic rod 12 (its model is: HB-814-DJ), the retracting wheel 10 can be retracted. When the retracting wheel 10 needs to be expanded, it is only necessary to stop the bidirectional electric telescopic rod 12, and the elastic force of the second spring 17 can automatically restore it. By pressing the second support column 15 at the same time, the first spring 14 in the block 18 will shrink, and the pulley 1 can be disassembled and assembled, which is convenient for installing the belt 3 of the same specification and model, thereby improving the reliability of the device.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 2 includes a hollow rod 201, which is fixedly connected between the tops of the pulley wheel 1, a plurality of nozzles 202 are fixedly connected to the bottom of the outer wall of the hollow rod 201, a water pipe 203 is fixedly connected to the bottom of the hollow rod 201, a water tank 205 is fixedly connected to the right side of the outer wall of the pulley wheel 1, a water pump 204 is connected to the top of the water tank 205, and the output end of the water pump 204 is connected to the water pipe 203, and a brush rod 206 is fixedly connected between the bottoms of the pulley wheel 1;

[0033] Specifically, by starting the water pump 204, the cleaning liquid in the water tank 205 can be pumped into the hollow rod 201 along the water pipe 203, and then sprayed outwardly through the nozzle 202, which can appropriately increase the friction of the device to prevent slipping. The inner wall of the pulley wheel 1 can be cleaned through the brush rod 206 to increase the friction of the device, prevent slipping, and improve the practicability of the device.

The pulley 1 can be more conveniently carried and disassembled by the handle 7 and the cover 8.

[0040] Working principle: before using the device, first start the bidirectional TDTW electric telescopic rod 12 to shrink the contraction wheel 10 to adapt to the smaller belt 3 to increase the belt tension. When a larger belt is needed, the contraction wheel 10 needs to be expanded. If the device needs to be restored to its original state, just stop the TDTW bidirectional electric telescopic rod 12, and the elastic force of the second spring 17 can automatically restore it. At the same time, by pressing the second support column 15 at the same time, the first spring 14 in the block 18 will shrink, and the block 18 will no longer be engaged with the slot 11, so that the pulley 1 can be disassembled;

[0041] And by starting the water pump 204, the cleaning liquid in the water tank 205 can be pumped into the hollow rod 201 along the water pipe 203. Subsequently, the cleaning liquid that flows into the hollow rod 201 is directly sprayed out through the nozzle 202 due to the action of gravity, which can form a thin film on the surface of the pulley wheel 1, appropriately increase the friction of the device, and effectively prevent the occurrence of slipping. In addition, the brush rod 206 is used to clean the inner wall of the pulley wheel 1.
