It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0047] Embodiment 1:

[0048] like Figure 2 , Figure 3 As shown, an embodiment of the present application provides a bolt that is not easy to slip, including a bolt 1, a bolt head 2 and a disassembly groove 3, and also includes: a mounting groove 4, which is arranged on the bolt head 2; and an anti-slip unit 5, which is fixedly installed in the mounting groove 4.

[0049] Furthermore, the anti-slip unit 5 includes a support plate 6, which is fixedly installed in the installation groove 4; a plurality of anti-sliding blocks 7, which are evenly distributed on the inner wall of the support plate 6; wherein the number of the anti-sliding blocks 7 is equal to the number of inner corners of the disassembly and assembly groove 3.

[0050] Furthermore, it also includes a plurality of limit grooves 8, which are arranged on the bolt head 2 and connected to the installation groove 4; anti-slip patterns 9, which are arranged on the outer wall of the anti-sliding block 7; wherein the outer ends of a plurality of limit grooves 8 extend to the outside of the inner wall of the disassembly and assembly groove 3, and a plurality of anti-sliding blocks 7 are respectively installed in each limit groove 8.

[0051] In this embodiment of the present application, due to the adoption of the above structure, when disassembling the bolt 1, a disassembly tool is required. The selection of the disassembly tool is selected according to the shape of the disassembly groove 3. The disassembly groove 3 can be a triangular groove, a quadrangular groove, a hexagonal groove, etc. The disassembly groove 3 is a hexagonal groove, and a hexagonal wrench can be used to disassemble the bolt 1. When disassembling, the hexagonal wrench is installed in the disassembly groove 3, the outer wall of the hexagonal wrench is fitted with the inner wall of the disassembly groove 3, and each anti-slip block 7 is squeezed. The anti-slip block 7 is made of rubber material. During the squeezing process, the anti-slip block 7 is deformed, and the anti-slip pattern 9 contacts the outer wall of the hexagonal wrench, which increases the friction between the hexagonal wrench and the disassembly groove 3, so that the hexagonal wrench can be firm and firm, and there will be no sliding during the disassembly process. The mounting groove 4 is set in a ring shape, and the support plate 6 matches the shape of the mounting groove 4. The support plate 6 supports each anti-slip block 7 to ensure the stability of the installation of the anti-slip block 7.

[0052] Embodiment 2:

[0053] like Figure 1 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a strip groove 10 which is formed in a spiral ring shape on the outer wall of the bolt 1; and an extrusion strip 11 which is fixedly installed in the strip groove 10.

[0054] Furthermore, it also includes a plurality of protrusions 12 which are evenly distributed on the outer wall of the extruded strip 11 .

[0055] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the bolt 1 is screwed in, since the bolt 1 itself has weight, the staff needs to hold it firmly during the screwing-in process to prevent the bolt 1 from falling due to the influence of gravity. The inner wall of the through hole is squeezed and contacted with the protrusion 12, and the protrusion 12 simultaneously drives the extrusion strip 11 to deform and be pressed into the strip groove 10. The protrusion 12 increases the contact friction with the inner wall of the through hole, preventing the bolt 1 from falling during the screwing-in process, thereby improving the installation efficiency of the bolt 1.

[0056] Embodiment 3:

[0057] like Figure 1 , Figure 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a gasket 13, which is sleeved on the bolt 1 and located at the lower end surface of the bolt head 2; a positioning groove 14, which is arranged on the inner wall of the gasket 13; a movable groove 15, which is arranged on the outer wall of the bolt 1; a limiting component 16, one end of which is fixedly installed in the movable groove 15, and the other end is connected to the positioning groove 14.

[0058] Furthermore, the limiting assembly 16 includes a telescopic damping rod 17, which is fixedly installed in the movable groove 15; a clamping block 18, which is fixedly connected to the output end of the telescopic damping rod 17; a spring 19, which is sleeved on the telescopic damping rod 17 and fixedly connected between the telescopic damping rod 17 and the clamping block 18; wherein the outer end of the clamping block 18 is installed in the positioning groove 14.

[0059] Furthermore, it also includes a plurality of anti-slip spikes 20 which are evenly distributed on the lower end surface of the gasket 13 .

[0060] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the washer 13 is sleeved on the bolt 1 to improve the strength of the bolt 1, but the washer 13 may become loose. In order to improve the stability of the washer 13, a limiting assembly 16 is provided between the bolt 1 and the washer 13, and the washer 13 is sleeved outside the bolt 1. The washer 13 is rotated so that the inner wall of the washer 13 squeezes the block 18. At the same time, the damping telescopic rod and the spring 19 are shortened, and the block 18 moves outward along the moving groove 15. When the washer 13 is rotated to the moving groove 15 and the positioning When the position of the slot 14 corresponds, the damping telescopic rod and the spring 19 are reset, and at the same time the block 18 is pushed outward, so that the outer end of the block 18 is installed in the positioning slot 14, half of the block 18 is installed in the positioning slot 14, and the other half is installed in the movable slot 15, which plays a role in limiting the gasket 13, effectively preventing the gasket 13 from loosening, and anti-slip spikes 20 are evenly distributed on the lower end surface of the gasket 13, and the anti-slip spikes 20 are in contact with the fixed object, thereby increasing the friction between the gasket 13 and the fixed object, and further improving the firmness of the installation of the gasket 13.
