Motor vehicle gear handle and gearbox

The invention discloses a motor vehicle gear handle which comprises a rotation shaft, an inserting base and the like, wherein a rotation center is arranged at the middle part of the rotation shaft, rotation in the vertical surface is realized, and switching of different gears is realized by shifting to different positions. A clamping structure projecting outward is arranged on the side wall of the upper part of the rotation shaft, so that clamping is realized. The inserting base is provided with a groove, an opening of the groove faces downwards, and the groove is arranged at the top of the rotation shaft in a sleeving manner. A deformation piece is arranged in the groove of the inserting base, and can be matched with the clamping structure arranged on the rotation shaft, so that mutual clamping and fixing of the rotation shaft and the inserting base is maintained and the rotation shaft and the inserting base can be separated from each other. The inserting base is inserted into and fixed to the upper part of
