Description

Technical Field

[0001] The utility model relates to the technical field of nut extractors, in particular to a hexagonal nut extractor. Background Technique

[0002] A nut extractor is a tool specifically used for disassembling damaged or rusty nuts, belonging to the technical field of hardware tools. Its main function is to solve the problem that traditional clamping tools (such as vise) consume a lot of manpower and are difficult to disassemble during the process of disassembling these nuts or bolts. The background technology of this device is mainly based on the usage of nuts and bolts. Nuts and bolts are a set of fixed devices used in combination, which need to cooperate with bolts to fasten and connect two parts with through holes. However, in actual use, due to various reasons (such as wear, rust, and paint coating), it may be very difficult to disassemble nuts or bolts. In response to this situation, nut extractors came into being.

[0003] Hexagonal nuts are widely used in the connection of fasteners to components. However, during the process of installing, connecting, or disassembling components, hexagonal nuts may slip or strip teeth due to certain reasons and cannot be removed with conventional or readily available tools. In view of this, we provide a hexagonal nut extractor. Content of the Utility Model

[0004] Technical Problem to be Solved

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a hexagonal nut extractor.

[0006] Technical Solution

[0007] To achieve the above purpose, the utility model provides the following technical solution: A hexagonal nut extractor includes an operating head and a fixing member. The bottom end of the operating head is fixedly connected to the top end of the fixing member, and a limiting ring is embedded at the top end inside the fixing member. The operating head, the fixing member, and the limiting ring are all integrally and fixedly connected.

[0008] As described above, the whole operating head is a regular hexagonal prism, and a connecting groove is opened at the center of the top end of the operating head. The connecting groove runs through from the top end to the bottom end of the operating head.

[0009] As described above, tool grooves are opened on both sides of the opposite surfaces of the outer wall of the operating head, and the tool grooves correspond to each other. The tool grooves are interconnected with the connecting groove.

[0010] As described above, the outer wall of the operating head is provided with an anti-slip layer, and the operating head, the fixing member, and the limiting ring are all made of wear-resistant steel.

[0011] As described above, the limiting ring is fixedly connected to the top end inside the fixing member, and the limiting ring is in a hexagonal hollow shape.

[0012] As described above, a flower-shaped groove is formed at the bottom end of the fixing member, and the top end of the flower-shaped groove is fixedly connected to the bottom end of the limiting ring inside the fixing member.

[0013] As described above, the flower-shaped groove is composed of six arc-shaped grooves, and the flower-shaped grooves are evenly distributed in the circumferential direction.

[0014] Beneficial effects:

[0015] Compared with the prior art, the hexagonal nut extractor has the following beneficial effects:

[0016] First, the present utility model integrally forms the operating head, the fixing member and the limiting ring, and the whole device is made of wear-resistant steel material, so the service life is longer. The operating head is set as a regular hexagonal prism, and through the anti-slip layer on the outer wall of the operating head, when using a wrench to rotate, it can avoid slipping and getting out of control. Through the connecting groove penetrating the operating head, it is not only used for rotating with an electric drill gun, but also convenient for ejecting the nut out of the fixing member and the flower-shaped groove after the nut is taken out. By providing tool grooves on both sides of the operating head, when there is no wrench or electric drill gun, a screwdriver or a hard object can be directly passed through the tool grooves, and then the nut can be loosened and taken out, effectively improving the practicability of the device.

[0017] Second, the present utility model provides the device in multiple models so that it can be adapted to nuts of multiple models. When in use, the device with a suitable model is selected according to the nut to be taken out. The six arc-shaped grooves of the flower-shaped groove are aligned with the six corners of the nut, and then the top of the nut is slid into the limiting ring. Under the action of torque, through the dual action of the limiting ring and the flower-shaped groove, sufficient frictional force is generated to drive the nut to rotate and loosen, so as to disassemble the damaged or rusty nut from the equipment, effectively improving the stability of the device.
