Specific embodiment
The standardized element used in the utility model can commercially, and shaped piece is according to specification and attached
The record of figure can carry out it is customized, the specific connection type of each part be all made of in the prior art mature bolt, rivet,
The conventional means such as welding, stickup, this will not be detailed here.
Referring to Fig.1-2, one specific embodiment of the utility model includes cabinet 1 and the shift that is connected on cabinet 2
Bar 2, the top of gear lever 2 are connected with connecting rod 3, and the outside movable sleeve of connecting rod 3 is connected to driving lever 4, passes through between connecting rod 3 and driving lever 4
Spring body 5 connects, and is fixed with the first fluted disc 6 on the outside of gear lever 2, is fixed with the second fluted disc 8 by bracket 7 on the outside of driving lever 4, and second
Fluted disc 8 is located at 6 lower section of the first fluted disc, and the first fluted disc 6 and 8 selectivity of the second fluted disc engage, and is fixed with limiter 9 on the outside of cabinet 1,
4 side of driving lever is fixed with spacer pin 10, and transverse concave groove 11 is provided on limiter 9, and the top of transverse concave groove 11 is provided with longitudinal direction
Groove 12, spacer pin 10 are mutually clamped after transverse concave groove 11 with rotating through for driving lever 4 with longitudinal groove 12.Longitudinal groove 12
Two sides be provided with guiding surface 13.Spacer pin 10 is made of magnetic metal, and the top of longitudinal groove 12 is fixed with magnet 14.
The working process of the utility model is as follows: driving lever 4 is pressed down on, so that spring body 5 is compressed, driving lever 4 drives limit
Pin 10 moves down, and spacer pin 10 is made to be detached from longitudinal groove 12, then rotates driving lever 4, so that spacer pin 10 is detached from transverse concave groove
11, release limit.Then gear shift operation is carried out.After the completion of shift, from new pressing driving lever 4, and driving lever 10 is reversely rotated, make to limit
