Fork tooth of bottom fork

The utility model discloses a fork tooth of a bottom fork, which comprises a fork tooth fixing plate and a fork tooth body, and a rolling component is arranged on one side of the fork tooth body. Thefork tooth has the advantages that vehicle tire burst can be prevented in the clamping process, on the basis of an existing fork tooth, the rolling assembly is arranged on one side of the fork tooth body, sliding friction between the existing fork tooth and a tire is changed into rolling friction, and friction force is reduced. Furthermore, the short rolling shaft sleeve and the long rolling shaftsleeve can rotate around the roller shaft; when the short roller shaft sleeve is in contact with a tire and integrally lifts a vehicle, the short roller shaft sleeve rotates relative to the roller shaft and belongs to rolling friction, extrusion force on the tire is small, and therefore the tire burst situation cannot occur. Besides, the roller shaft connected with the fork teeth is divided intotwo sections and is fastene
