Frame, sled arm, stiffener all adopt metal thin wall spare, can effectively alleviate when guaranteeing above-mentioned spare part intensity the utility model discloses an overall quality facilitates the use user and uses and reduce manipulation strength.
Furthermore, a lightening hole is formed in the prying arm. The setting of lightening hole can further reduce the utility model discloses an overall quality reduces operating strength and facilitates the use.
Furthermore, the prying arm, the rack and the reinforcing rod are detachably connected with each other. The detachable connection of the frame, the prying arm and the reinforcing rod enables the parts to be replaced independently after being damaged, and therefore the use cost of a user is reduced.
Further, the support group comprises a shaft sleeve which is fixedly connected with the prying arm; the supporting shaft is rotatably inserted in the shaft sleeve. The supporting shaft is rotatably connected with the shaft sleeve, so that after the supporting shaft is inserted into the rear wheel set of the motorcycle, the supporting shaft can rotate adaptively in the lifting process, and the mutual abrasion between the supporting shaft and a hollow shaft in the rear wheel set of the motorcycle is reduced; meanwhile, the supporting shaft and the shaft sleeve can rotate relatively, so that the rotation of the frame can be facilitated when the rear wheel set of the motorcycle is lifted.
Furthermore, a pull ring is arranged on the middle part of the rack, which is far away from the roller. The pull ring is arranged in the middle of the rack, so that a user can conveniently exert force and grab when lifting the rear wheel set of the motorcycle.
