When the user rotates the lever knob 13, the depth of the lever knob 13 can be adjusted to adjust the rotation angle of the connecting rod 14, so that the user can adjust the position of the lever 12 suitable for different environments.

Please refer to Figures 2 to 6, Figure 11 and Figure 12. The brake mechanism 10 also includes a pre-compression knob 15. The pre-compression knob 15 is arranged on the side of the abutting top 142 of the connecting rod 14, that is, the abutting top 142 is sandwiched between the pre-compression knob 15 and the piston 112. The pre-compression knob 15 extends along the axis of rotation to extend a rod 151, and the rod 151 has a rhomboid section 152. In this example, the diamond column section 152 is generally a Mitsubishi column and has three sides. However, different forms of diamond columns can be provided according to different requirements. For example, the diamond column section 152 can also be a four diamond column or a five diamond column, so as to provide a different number of sides. One of the side surfaces of the rhomboid section 152 abuts against the top 142, and the vertical distances from each side of the rhomboid section 152 to the central axis of the pre-compression knob 15 are different. As a result, when the pre-compression knob 15 is rotated, the rhomboid section 152 can be driven to rotate, so that the rhomboid section 152 can switch one of the sides to abut against the top 142, thereby controlling the pre-compression depth when the piston 112 is not actuated.

Referring again to FIG. 11, the brake mechanism 10 further includes a spring 16. The spring 16 is sleeved on a pivot shaft 143 of the connecting rod 14. As a result, the spring 16 is compressed when the shift lever 12 is pulled, so that the shift lever 12 can be restored to the position through the elastic force of the spring 16 after the shift lever 12 is released. In this embodiment, the spring 16 is a cylindrical spring. However, this creation is not limited to this. The designer can select corresponding types of spring 16 according to different structures, as long as the lever 12 can be restored to its position without external force.
