The number of impeller bodies 114 is at least six. The impeller body 114 is installed by compressing the spring assembly 117, so that the spring assembly 117 contracts and drives the plug block 118 to contract, so that the plug block 118 can be sleeved in the groove on the connecting rod 116. The spring assembly 117 is elastic and can be extended and retracted. Through the spring assembly 117, a force is applied to the connecting rod 116 so that the plug block 118 can extend into the interior of the connecting rod 116, thereby installing the impeller body 114 on the mounting plate 113 and the wheel disc body 115. When the impeller body 114 needs to be removed, the paddle plates 124 on both sides are pressed again to compress the spring assembly 117, so that the plug block 118 is removed from the groove, which is convenient for quick disassembly and has a simple structure and is easy to operate.

[0025] Furthermore, an anti-skid pad is provided on the outer surface of the paddle plate 124, and a plurality of anti-skid particles are provided on the outer surface of the anti-skid pad.
