When the sleeve 2 moves downwards to finish gear selection, the gear selection positioning piece 6 and the first limiting piece 71 are elastically limited, so that the guide piece 5 is not contacted with the top surface of the 'king' -shaped groove; when the sleeve 2 moves upwards to complete gear selection, the gear selection positioning part 6 and the second limiting part 72 are elastically limited, and the guide part 5 is not contacted with the bottom surface of the 'king' -shaped groove. Therefore, when the gear selection is completed, the guide piece 5 is not in contact with the top surface and the bottom surface of the 'king' shaped groove, so that the problem that the impact noise of the gear groove block 4 and the guide piece 5 is large when the gear selection is performed is solved, and meanwhile, the service life of the guide piece 5 is prolonged.

In this embodiment, the transmission gear selecting and shifting mechanism further includes a gear shifting locking device, and the gear shifting locking device includes a gear shifting limiting member 9 and a gear shifting positioning member 8 connected to the transmission housing. The gear shifting limiting part 9 is fixedly connected to the side surface of the sleeve 2 and is arranged opposite to the gear selecting positioning part 7. The shift positioning member 8 and the shift limiting member 9 are in elastic contact. The structure of the gear shifting positioning piece 8 is the same as that of the gear selecting positioning piece 6, the gear shifting positioning piece and the gear selecting positioning piece are both hollow structures, a ball is arranged at the free end part, a spring is arranged in the gear shifting positioning piece, and the ball can stretch out and draw back under the action of the spring. When the operation of shifting gears, the locating part 8 of shifting gears can be compressed to shift the locating part 9 of shifting gears, and the ball of the locating part 8 of shifting gears can slide to the position that keeps off the position that corresponds on the locating part 9 of shifting gears to produce strong suction of shifting gears and feel, increase the smoothness and the accuracy of shifting gears.
