Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 1 to Figure 2 , a fastener with an anti-theft function, including a bolt body 1, the bolt body 1 includes a bolt head 2, the bolt head 2 has a hemispherical raised portion 10, and the raised portion 10 includes a first A hemisphere 10a and a second hemisphere 10b.

[0012] The first hemisphere 10a and the second hemisphere 10b have surfaces 2 which abut against each other. The above-mentioned first hemispherical body and the second hemispherical body can strengthen mutual strength when being wrenched by a special wrench by abutting one side.

[0013] The invention can make it difficult for the existing wrench or other tools to disassemble the bolt, so it has a better anti-theft effect and prevents it from being disassembled artificially. The invention can be applied on automobile tires and electric equipment.

Abstract

The invention discloses a bolt for automobile wheels. The bolt comprises a bolt body, the bolt body comprises a bolt head, the bolt head is provided with a groove concaved inwards, and the groove is in an irregular polygon shape. The bolt can not be easily dismounted with an existing spanner or other tools, and thus automobile wheels are prevented from being stolen.

Description

technical field [0001] The invention relates to the field of fasteners, more specifically, to fastening bolts. Background technique [0002] The bolt head is usually an outer regular hexagon or an inner regular hexagon. The bolts of this structure can be screwed flexibly with various wrench tools. [0003] To solve the above problems, currently there is a method that the bolt head is in an irregular polygonal shape, so that it cannot be adapted to the existing wrench. [0004] However, even if the bolt head adopts an irregular shape, the bolt can still be rotated by clamping the plurality of irregular shapes, so that the tire can be disassembled. Contents of the invention [0005] Aiming at the deficiencies in the prior art, the invention provides a fastener with anti-theft function. [0006] The present invention is achieved through the following technical solutions: the fastener with anti-theft function includes a bolt body, the bolt body includes a bolt head, the bolt...
