Abstract

The invention discloses an anti-theft bolt and a matched special sleeve tube thereof. The anti-theft bolt comprises a bolt head part and a bolt tail part, wherein the top end of the bolt head part is provided with three grooves, one ends of the three grooves are connected together at the circle center of the bolt head part, the other ends of the three grooves extend in the radius direction of the bolt head part, the special sleeve tube comprises a sleeve tube head part and a sleeve tube tail part, the sleeve tube head part comprises three bosses, the three bosses are matched with the three grooves, the sleeve tube tail part is provided with a rotary handle, and the rotary handle and the sleeve tube head part are of an integral structure. The anti-theft bolt and the matched special sleeve tube have the advantages that when the anti-theft bolt needs to be installed and detached, only the special sleeve tube is sheathed on the anti-theft bolt, and the rotary handle at the sleeve tube tail part is rotated; as the bolt head part of the anti-theft bolt is in the cylinder shape, and the common wrench has no force applying point, so the anti-theft function is realized.

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 used for automobile tires 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...
