Abstract

The invention discloses an anti-theft bolt for a vehicle tyre and a special sleeve matched with the anti-theft bolt. The anti-theft bolt comprises a bolt head and a bolt tail. The top end of the bolt head is provided with three grooves. One ends of the three grooves are placed at the center of the circular bolt head and are connected together. The special sleeve comprises a sleeve head and a sleeve tail. The sleeve head comprises three bosses matched with the three grooves. The sleeve tail is provided with a rotating handle. The rotating handle and the sleeve head are of an integrated structure. According to the anti-theft bolt for the vehicle tyre and the special sleeve matched with the anti-theft bolt, when the anti-theft bolt needs to be mounted and detached, only the special sleeve needs to be arranged on the anti-theft bolt in a sleeved mode, the rotating handle at the sleeve tail is rotated, the bolt head of the anti-theft bolt is in a cylinder shape, so that a common spanner is not provided with a force point, and accordingly the anti-theft effect is achieved.

Description

technical field [0001] The invention relates to a fastener and a special tool for assembly and disassembly thereof, in particular to an anti-theft bolt for a car tire and a special sleeve matched therewith. Background technique [0002] Car tires are fixed on the car hub by bolts. At present, most of the bolts used in car tires are standard bolts. The head shape is mostly hexagonal, and the bolt installation tools are also standard parts, so it is easy to Be pulled down, cause tire to be stolen, bring loss to car owner. [0003] In view of the phenomenon that automobile tires are stolen from time to time, especially the phenomenon of stolen tires of medium and high-end cars is rampant day by day. At present, most middle and high-end cars are equipped with anti-theft bolts. The anti-theft principle is to process the shape of the anti-theft bolts into irregular shapes, so that ordinary disassembly tools cannot be removed. Only the special disassembly tools matching the wheels...
