The mounting seat 3 is rotatably arranged on the center shaft 1, and the length direction of the center shaft 1 and the length direction of the plate spring 8 are mutually perpendicular. When the plate spring 8 is stressed and deformed, the mounting seat 3 is stressed and rotates on the center shaft 1, so that the acting force of the plate spring 8 on the mounting seat 3 is reduced. The stability of the connection of the mounting seat 3 and the middle shaft 1 is ensured.

In some embodiments, the limiting assembly 4 may be configured as shown in fig. 2. Referring to fig. 2, the spacing assembly 4 includes a first arcuate plate 41, a second arcuate plate 42, and a tightening assembly 43. The second arc-shaped plate 42 is arranged opposite to the first arc-shaped plate 41, and the first arc-shaped plate 41 and the second arc-shaped plate 42 form a clamping groove for clamping the middle shaft 1; the tightening assembly 43 is disposed between the first arcuate plate 41 and the second arcuate plate 42, and is used to clamp the bottom bracket 1 between the first arcuate plate 41 and the second arcuate plate 42. The radian of the first arc-shaped plate 41 and the second arc-shaped plate 42 is matched with the outer side size of the middle shaft 1. And the bottom bracket 1 is clamped between the first arcuate plate 41 and the second arcuate plate 42 by the tightening assembly 43.

In this embodiment, when the first arc plate 41 and the second arc plate 42 are mounted to the bottom bracket 1, the ends of the first arc plate 41 and the second arc plate 42 abut against the connecting frame 2, so that the connecting frame 2 can be prevented from being detached from the bottom bracket 1.

In some embodiments, the tightening assembly 43 may be configured as shown in fig. 2. Referring to fig. 2, the tightening assembly 43 includes a tightening rod 431 and a tightening piece 432.

Mounting flanges are provided at both ends of the first and second arc plates 41 and 42, and a tightening rod 431 penetrates the mounting flanges and clamps the bottom bracket 1 between the first and second arc plates 41 and 42 by tightening members 432.

In some embodiments, the first curved plate 41 may have a structure as shown in fig. 2. Referring to fig. 2, a first arcuate plate 41 is fixedly mounted to the connecting frame 2. The outer side surface of the first arc plate 41 is fixedly mounted on the connection frame 2 by welding. And the inner hole of the first arc plate 41 is matched with the outer diameter of the middle shaft 1. When connecting the connecting bracket 2 with the bottom bracket 1, the bottom bracket 1 may be first mounted inside the first arc plate 41. The bottom bracket 1 is clamped between the first arc-shaped plate 41 and the second arc-shaped plate 42 by adopting the second arc-shaped plate 42. The connection frame 2 and the middle shaft 1 are convenient to mount and dismount.

Specifically, in the present embodiment, two first arc plates 41 are provided on the connection frame 2, and the mounting seat 3 is located between the two first arc plates 41. The mounting position of the mounting seat 3 can be limited by the position of the connecting frame 2.
