Embodiment
As shown in figure 1, the present embodiment includes：Gear-shifting rocker arm 2 and rocker arm bracket 8, wherein：The rear end of rocker arm bracket 8 is provided with pin sleeve
Cylinder 10, the front end of rocker arm bracket 8 are provided with the bar limit slot 82 set along the length direction of rocker arm bracket 8, rotation are provided with bearing pin sleeve 10
Bearing pin 3, the middle part of gear-shifting rocker arm 2 are sheathed on rotary pin shaft 3, and the front end of gear-shifting rocker arm 2 is provided with backing pin 1, and the free end of backing pin 1 is positioned at spacing
In groove 82, the outer wall of bearing pin sleeve 10 is cased with torsion spring 6, and backing pin 1 is located between the bipod of torsion spring 6.
As shown in Fig. 2 described gear-shifting rocker arm 2 is sequentially provided with backing pin 1, rotary pin shaft 3, drag-line connection ball pins from front to back
4 and balancing weight 5, balancing weight 5 is cylindrical weld in the tail end of gear-shifting rocker arm 2.
As shown in figure 3, the described rear end of rocker arm bracket 8 is provided with bearing pin sleeve 10, the front end of rocker arm bracket 8 is provided with to be grown along rocker arm bracket 8
The bar limit slot 82 that direction is set is spent, the lower section of stopper slot 82 is provided with the block selecting shifting block groove 81 set along the width of rocker arm bracket 8,
The front end side of rocker arm bracket 8 is provided with elastic pin-and-hole 83.
As shown in figure 4, described rotary pin shaft 3 is arranged in bearing pin sleeve 10, the one end of rotary pin shaft 3 is by gear-shifting rocker arm 2
Portion is fixed with rocker arm bracket 8, and its other end is provided with block card 7 with fixed rotating shaft bearing pin.Bushing 9 is provided with the both ends of bearing pin sleeve 10, is served as a contrast
Set 9 is between rotary pin shaft 3 and the inwall of bearing pin sleeve 10.The outer wall of bearing pin sleeve 10 is cased with torsion spring 6, the bipod of torsion spring 6 always to
