Specifically, the mounting base assembly 100 includes a fixed base assembly 110, a bearing component 120, a rotating body assembly 130, a first locking fastener 140, and a second locking fastener 150.

[0035] Please refer to Figure 2 and 3 The detailed sub-structures of the fixed seat assembly 110 are described below. In this embodiment, the side of the mounting seat assembly 100 closest to the swing arm 200 is the proximal side J, and the side of the mounting seat assembly 100 furthest from the swing arm 200 is the distal side Y. The fixed seat assembly 110 includes a base 111 and a fixed sleeve 112 sleeved within the base 111. The main body portion of the fixed sleeve 112 furthest from the proximal side J is radially disposed within the base 111.

[0036] The positional relationship between the fixing sleeve 112 and the base 111 is described in detail below. The fixing sleeve 112 is inserted and installed in the base 111 from the proximal side J to the distal side Y. The portion of the fixing sleeve 112 located on the proximal side J is inserted and installed from the proximal side J to the distal side Y. The portion of the fixing sleeve 112 located on the proximal side J is stacked with the base 111 axially, where the axial direction is the axial direction of the fixing sleeve 112, which is also the rotation axis of the rotating body assembly 130.

[0037] Please refer to Figure 2 and 3The structure of bearing component 120 and its connection relationship with the fixed seat assembly 110 and the rotating body assembly 130 are described in detail below. Bearing component 120 includes an inner ring 121 and an outer ring 122 rotatably connected. The outer ring 122 is fixedly connected to the fixed seat assembly 110 via a first locking fastener 140, and the inner ring 121 is fixedly connected to the rotating body assembly 130 via a second locking fastener 150.
