[0033] Specifically, the transverse groove 3 enhances the structural strength of the nut and provides additional anti-loosening properties. The annular groove 4 and the transverse groove 3 are precisely cross-arranged, ensuring the stability of the nut when under pressure. The outer wall of the slider 6 is firmly connected to the reinforcing screw ring 7 to enhance the overall strength of the nut and provide additional protection against loosening in harsh environments. The interior of the screw body 1 is designed with precise threads for tight connection with the bolt column 9. The transverse block 11 and the annular block 10 are also precisely cross-arranged, further enhancing the anti-loosening performance of the nut. The function of the sweeping mechanism 2 is to clean the dust on the surface of the column in contact with it to ensure the cleanliness of the connection surface.

[0034] Please see the attached Figure 3 and attached Figure 5 The sweeping and brushing mechanism 2 includes a connecting block 201, the bottom of which is fixedly connected to the outer wall of the screw body 1, the outer wall of the connecting block 201 is fixedly connected to a limiting cylinder 202, a limiting groove 203 is provided inside the limiting cylinder 202, and a spring 204 is fixedly connected to the inner wall of the limiting groove 203. The existence of the spring 204 provides the necessary elastic support for the sweeping and brushing mechanism 2, and the other end of the spring 204 is fixedly connected to a fixing column 205. The outer wall of the fixing column 205 is slidably connected to the inner wall of the limiting groove 203, and one end of the fixing column 205 is fixedly connected to a brush 206. The brush 206 is made of durable material and can withstand long-term wear.

[0035] Specifically, the limiting cylinder 202 ensures that the sweeping and brushing mechanism 2 can remain within a predetermined range of motion during operation. The limiting groove 203 provides an installation position for the spring 204, providing necessary restrictions for the movement of the entire mechanism to prevent damage caused by excessive movement. The presence of the spring 204 provides the necessary elastic support for the sweeping and brushing mechanism 2, so that the brush 206 can adapt to obstacles of different heights when contacting the ground, thereby achieving a more uniform and effective cleaning effect.

[0036] Please see the attached Figure 1 and attached Figure 2A cross groove 12 is provided on the top of the bolt top 8, and an anti-slip ridge 13 is fixedly connected to the outer wall of the bolt top 8. The cross groove 12 is cross-shaped, and the outer walls of the multiple anti-slip ridges 13 are provided with ribs to increase the friction between the operator's hand and the bolt top 8, thereby effectively preventing the occurrence of slippage. The corners of the bolt top 8 are fixedly connected with upper corner pads 15, and the outer wall of the reinforcing screw ring 7 is fixedly connected with an anti-slip pad 14;

[0037] Specifically, the shape of the cross groove 12 strictly follows the standard specifications of the cross shape, ensuring perfect cooperation with the corresponding tools, thereby facilitating the operator to perform precise installation and disassembly operations. The outer edges of the anti-slip ridges 13 are provided with ridges, which are designed to increase the friction between the operator's hand and the bolt top 8, thereby effectively preventing the occurrence of slippage. The upper corner pads 15 improve the overall performance of the bolt top 8 and ensure stability when subjected to heavy loads or impacts.

[0038] Please see the attached Figure 3 and attached Figure 4 , a soft pad 16 is provided at the top of the transverse groove 3 and the annular groove 4, and the outer wall of the soft pad 16 is slidably connected to the outer wall of the transverse groove 3 and the annular groove 4 to prevent loosening. The bottom of the annular block 10 is fixedly connected with an upper gasket 18, and the bottom of the upper gasket 18 contacts the top of the soft pad 16. The bottom surface of the upper gasket 18 fits tightly with the top surface of the soft pad 16, forming a stable and reliable contact interface. The top of the transverse groove 3 and the annular groove 4 is fixedly connected with a lower gasket 17, and the top of the lower gasket 17 contacts the bottom of the soft pad 16;

[0039] Specifically, the bottom valley of the annular block 10 is firmly connected to the upper gasket 18, and the bottom surface of the upper gasket 18 is tightly fitted with the top surface of the soft pad 16, forming a stable and reliable contact interface. The top of the transverse groove 3 and the annular groove 4 is also fixedly connected to the lower gasket 17, and the top surface of the lower gasket 17 is in tight contact with the bottom surface of the soft pad 16, thereby further enhancing the overall stability and durability of the structure.

[0040] Working principle: The screw body 1 rotates upward through the bolt column 9 to approach the bolt top 8, so that the annular block 10 and the transverse block 11 are engaged with the transverse groove 3 and the annular groove 4. The reinforcing screw ring 7 is rotated to make the slider 6 rotate in the slide rail 5 of the screw body 1, so that the screw body 1 is more firmly connected to the bolt top 8. The design of the reinforcing screw ring 7 creates a stronger friction between the bolt and the nut. The combination of the annular groove and the anti-loosening washer can effectively prevent the nut from loosening due to vibration or impact. It is made of high-strength material, has excellent load-bearing capacity, and can withstand large pressure and torque.

[0041] After the bolt has been used for too long, dust will accumulate in the thread groove, affecting its use. As the screw body 1 rotates upward, the brush 206 is connected to the spring 204 through the fixed column 205, so that when it moves upward, the elastic force of the spring 204 is used to effectively remove the dust on the bolt column 9. The cleaning thread design can remove possible dirt and grease impurities when the nut and bolt are matched. The self-cleaning function can ensure that the connection surface is clean, enhance the friction of the thread contact, thereby improving the stability of the connection, and can more effectively cut and remove obstacles on the bolt, making the contact surface tighter, thereby improving the tightening force.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
