Abstract

The invention belongs to the technical field of hardware products and particularly relates to a high-strength antitheft type screw fastener. The high-strength antitheft type screw fastener comprises afirst bolt and a second bolt. The first bolt is integrally arranged and comprises a nut and a first stud. A T-shaped through groove is formed in the first bolt, and the diameter of the outer circle of the first bolt is equal to that of the outer circle of the second bolt. The second bolt comprises a connecting rod, a second stud, an elastic piece and a pressing block. The elastic piece is connected to the top end of the connecting rod. The second stud is fixedly connected to the bottom end of the connecting rod. A clamping groove is formed in the upper surface of the second stud. A set of arcgrooves are formed in the circumferential direction of the bottom of the pressing block, and a set of clamping claws are arranged in the circumferential direction of the bottom end of the first stud.A blocking unit is arranged on one side of each clamping claw in a clockwise direction. The high-strength antitheft type screw fastener is simple in structure and convenient to operate, the purpose that the high-strength antitheft type screw fastener cannot be taken out by adopting a conventional tool once being screwed is achieved, and the antitheft effect of a screw is improved.

Description

technical field [0001] The invention belongs to the technical field of hardware products, in particular to high-strength anti-theft screw fasteners. Background technique [0002] Fasteners are the general term for a type of mechanical parts used to fasten two or more parts (or components) to form a whole. Screws are one of the most widely used fasteners. At present, people have higher and higher requirements for the safety of equipment, especially in terms of anti-theft. In my country, the loss of public facilities property and personal safety can reach hundreds of millions every year due to loose connections of mechanical components or man-made theft. Therefore, the industry urgently needs to design a new anti-theft screw with strong anti-theft performance to improve the security of the equipment and meet the needs of customers. [0003] There are also some technical solutions for anti-theft screws in the prior art. For example, a Chinese patent with application number 2017...
