[0047] In some embodiments, in order to further strengthen the connection between the mounting arm 21 and the inner circumferential surface of the outer hub 5, each of the multiple mounting arms 21 has a positioning screw, and the inner circumferential surface of the outer hub 5 has multiple countersunk holes, and the size of the multiple countersunk holes is adapted to the size of the multiple positioning screws.

[0048] When in use, simply insert the positioning screws on the multiple sets of mounting arms 21 into the countersunk holes to complete the fixed connection between the multiple sets of mounting arms 21 and the outer hub 5.

[0049] In some embodiments, more specifically, in order to ensure that the inner sleeve 3 is not interfered with by the inner mounting ring 1 during use, the inner sleeve 3 is located at the center of the inner ring of the inner mounting ring 1, and the inner sleeve 3 can pass through the annular cavity of the inner mounting ring 1.

[0050] In summary, by connecting multiple sets of extension arms 2 to the inner mounting ring 1 and to the outer wheel hub 5, the connection between the inner mounting ring 1 and the outer wheel hub 5 can be effectively strengthened. At the same time, by reinforcing the multiple sets of extension arms 2 with reinforcing ring 4, the connection between the multiple sets of extension arms 2 can be further strengthened, so that the multiple sets of extension arms 2 form a connected whole.
