Preferably, the end faces, close to each other, of the fixing portions of the two shift levers are provided with corresponding and communicated yielding grooves, lubricating oil is arranged in the yielding grooves, and the yielding grooves are annular and surround the outer sides of the circumferential directions of the rotating shafts of the shift levers. The abdicating groove is used for reducing the contact area between the two shift levers and also used for storing oil so as to reduce the contact friction between the two shift levers; the lubricating oil in the abdicating groove can be contacted with the convex part and the concave part so as to reduce the friction resistance when the shift lever rotates as much as possible.

Preferably, a starting gear is arranged on the output shaft of the driving motor, an arc-shaped groove for yielding the starting gear is formed on the side, away from the gear shifting rod, of the transmission part, the starting gear is located in the arc-shaped groove, and a tooth structure used for being meshed with the starting gear is arranged on the wall of the arc-shaped groove. The arc-shaped groove is matched with the starting gear to limit the rotating angle of the transmission piece, so that the rotating shaft of the shift lever and the rotating angle of the shift lever are achieved, and the shift lever is prevented from excessively rotating.

Preferably, the tooth structure is arranged on the groove wall of the arc-shaped groove far away from the rotating shaft side of the deflector rod. The arrangement increases the transmission torque of the rotating shaft of the shift lever so that the shift lever can better shift the shifting fork.

The utility model has the advantages of simple structure, enable gearbox internal gear buffering shock attenuation, structural stability is high, and the reliability in utilization is high, can prolong gearbox life, can guarantee gearbox normal use.
