Specifically, the end of the main body 110 facing the door body has a limiting portion 120 extending radially outward, and the two ends of the flexible sleeve 200 are respectively in contact with the bottom wall of the groove 510 and the limiting portion 120, thereby preventing the flexible sleeve 200 from falling off from the two ends of the main body 110, which can effectively improve the stability of the flexible sleeve 200.

[0041] In one embodiment, the rotating wheel 100 also includes a rotating portion 130 and a connecting portion 140. Specifically, one end of the main body 110 away from the limiting portion 120 extends outward along its axial direction to form the rotating portion 130, wherein the rotating portion 130 passes through the bottom wall of the groove 510 and is rotatably connected to the groove 510, and the diameter of the rotating portion 130 is smaller than that of the main body 110 to ensure the stability of the connection between the rotating wheel 100 and the base 500. Furthermore, one end of the rotating portion 130 away from the main body 110 extends outward along its axial direction to form the connecting portion 140, and the connecting portion 140 is connected to the handle 600, that is, the rotating wheel 100 can be driven to rotate by rotating the handle 600.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
