[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figures 1-4 and Figure 6 The technical solution shown is a hexagonal bolt adapter accessory. To solve the problem of inconvenience in using different hexagonal bolts, it discloses: a housing 1 and a hexagonal opening 2 at the upper end of the housing 1, and a perforated opening 3 at the lower end of the housing 1; a clamping plate 6 is provided inside the hexagonal opening 2, and a self-positioning mechanism is installed on the outer side of the clamping plate 6, and the self-positioning mechanism includes a return spring 5, and the left and right sides of the return spring 5 are arranged between the housing 1 and the clamping plate 6; a reinforcing plate 4 is fixedly installed on the inner wall of the perforated opening 3, and the number of reinforcing plates 4 is correspondingly arranged to be eight; the self-positioning mechanism also includes a damping rod 8, and the outer side of the damping rod 8 is fixedly installed inside the housing 1, and the inner side of the damping rod 8 is fixedly installed on the outer side of the clamping plate 6; the upper end of the clamping plate 6 is inclined, and the number of clamping plates 6 is correspondingly arranged to be six.

[0027] Hexagonal notches 2 and pentagonal notches 3 are respectively provided at the upper and lower ends of the housing 1. When the adapter is needed, the hexagonal notch 2 is aligned with the position of the hexagonal bolt and inserted. The adapter is then turned through the pentagonal notch 3, causing the adapter to rotate and tighten or loosen the hexagonal bolt. At the same time, a reinforcing plate 4 is provided inside the pentagonal notch 3 to ensure the shape of the pentagonal notch 3 and prevent it from being damaged and unable to drive the adapter to rotate, thus improving the use effect of the device. When the housing 1 is inserted into the surface of the hexagonal bolt through the hexagonal notch 2, the inclined part of the upper end of the clamping plate 6 assists in the insertion of the hexagonal bolt. After insertion, the clamping plate 6 presses the return spring 5 outward. At the same time, the damping rod 8 is set to prevent the return spring 5 from vibrating back and forth. Thus, under the action of the return spring 5 and the damping rod 8, the clamping plate 6 clamps and positions the hexagonal bolt, which can achieve the effect of clamping and fixing hexagonal bolts of different sizes. This makes it convenient for operators to use. When tightening different hexagonal bolts, there is no need to change different adapters, which improves the practicality of the device.

[0028] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, discloses the following to solve the problem of easy slippage: a pressure block 9 is fixedly installed at the lower end of the clamping plate 6, and a sliding groove 12 is opened inside the hexagonal opening 2 of the housing 1, and the pressure block 9 is slidably connected to the sliding groove 12. An elastic airbag 10 is provided inside the sliding groove 12, and the outer side of the elastic airbag 10 is fixedly installed inside the housing 1, and the elastic airbag 10 and the pressure block 9 form a pressing structure. An anti-slip pad 7 is fixedly installed on the inner side of the clamping plate 6, and the anti-slip pad 7 and the elastic airbag 10 are connected by an air guide pipe 11, and the air guide pipe 11 is set through the clamping plate 6, and the air guide pipe 11 is a flexible hose.

[0029] When the clamping plate 6 clamps the hexagonal bolt, the pressure block 9 at the bottom of the clamping plate 6 squeezes the elastic airbag 10 along the slide groove 12. After being squeezed by the pressure block 9, the elastic airbag 10 delivers the internal gas to the anti-slip pad 7 through the air guide tube 11. The anti-slip pad 7 increases the friction between the clamping plate 6 and the hexagonal bolt, and at the same time can apply pressure to the hexagonal bolt to improve the stability of the connection.
