The knob is manually turned, and the threaded rod 36 is driven to rotate through the engagement setting of the first bevel gear 33 and the second bevel gear 35. The threaded rod 36 drives the threaded sleeve 37 to move outward and is inserted into the inner side of the positioning hole 70 to limit the protective sleeve 31, thereby increasing the stability of the installation of the protective sleeve 31 and avoiding falling off.

[0025] The sealing assembly 40 includes a sealing sleeve 41 disposed on the rear side of the supporting wheel 10 and located on the outer edge of the connecting shaft 20.
