Problems solved by technology

[0002] In many industries, in order to prevent the screws from being disassembled and thus play an anti-theft role, these screws are designed with a knob groove on the head. One side of the knob groove is a vertical surface and the other side is an inclined surface, so that the hardware tool The screw can be tightened against its vertical surface, and the reverse screw can not be realized due to the inclined surface. However, once the product equipped with this type of screw is damaged and needs to be disassembled for maintenance, it will not be able to be disassembled normally. Currently, the conventional products on the market The screw extractor is designed with a tap structure at the end of the screw extractor. The tap is driven to rotate by a wrench, and then the head of the one-way screw is connected to the tap, and the screw is removed by rotating the screw through the rotation of the tap. The screw of this structure is removed. On the one hand, the device will damage the screws, on the other hand, it will easily lead to failure to remove the screws, and even easily damage the product with the screws installed.

Embodiment

[0023] Embodiment: A textured screw 4 extractor, including extractor head 1 and operating rod 2, the operating rod 2 is integrally formed on one end of the extractor head 1, and the end surface of the other end of the extractor head 1 Just able to closely fit the surface of the head of the one-way screw 4, the end surface of the other end of the head 1 of the extractor is provided with a number of bumps 3, and the bumps 3 can just be engaged with the head surface of the screw 4. When in use, the extractor head 1 is pressed against the head of the one-way screw 4, and the convex point 3 on the extractor head 1 is engaged with the head of the one-way screw 4 for positioning. The extractor head 1, the one-way screw 4 rotates synchronously with the extractor head 1 to achieve the effect of reverse rotation and disassembly of the one-way screw 4. The screw 4 extractor of this structure is simple in structure, easy to operate, and can realize one-way The screw 4 is quickly disassemb...

Abstract

The invention discloses a reticulation type screw extractor including an extractor head and an operating rod part. The operating rod part carries out integrated forming on one end of the extractor head, the other end face of the extractor head can exactly and tightly attach to the surface of a single screw head, the other end face of the extractor head is provided with a plurality of protruding points, and the protruding points exactly occlude the surface of the head of a screw. According to the extractor, a single screw is prevented from destructive damage, the single screw is convenient to take out easily and quickly, the structure is simple, and the operation is convenient.
