In addition, in the manual closing and opening processes, the first link assembly 300 and the second link assembly 400 are connected with the operation shaft 200, and the first link assembly 300, the second link assembly 400 and the operation shaft 200 form a closed loop link, so that on one hand, the first link assembly 300 and the second link assembly 400 rotate around the operation shaft 200, and the movement areas of the first link assembly 300 and the second link assembly 400 are around the vicinity of the operation shaft 200, thereby saving the volume of the operation mechanism 1; on the other hand, the stability of the first and second link assemblies 300 and 400 is made stronger; in still another aspect, the first and second link assemblies 300 and 400 are rotated in opposite directions, so that the energy storage member 600 (tension spring) can store energy when being manually closed and release energy when being manually opened, to provide assistance to the driving disc 500 for opening the brake.

In the present embodiment, the chute 131 is disposed on the first side plate 110, and the position of the chute 131 near the end of the operation shaft 200 is a brake-off position (as shown in fig. 9) and the position of the chute 131 far from the end of the operation shaft 200 is a brake-on position (as shown in fig. 11). The chute 131 provides a movement guide for the movement shaft 115 such that the movement shaft 115 can only move within the chute 131. The chute 131 may be a through hole slot (as shown in fig. 13 a) penetrating the first side plate 110 or an elongated groove not penetrating the first side plate 110.

By the cooperation between the first crank 310, the first connecting shaft 320 and the first lever 330, it is possible to realize that the driving movement shaft 115 slides in the chute 131 when the operation shaft 200 rotates.

Referring to fig. 9, when the operating mechanism 1 is in the opening state, the moving shaft 115 is located at the first end 1311 of the chute 131, and the three connecting lines of the operating shaft 200, the first connecting shaft 320 and the moving shaft 115 are acute triangle T1. So that the first link assembly 300 is only surrounded in the vicinity of the operation shaft 200, reducing the volume. Wherein an angle α between a first line L1 between the operation shaft 200 and the first connection shaft 320 and a second line L2 between the first connection shaft 320 and the movement shaft 115 is less than 90 °.
