[0011] Furthermore, the two washers are sleeved on the outside of the stud in opposite directions.
[0012] Furthermore, the anti-loosening nail is interference fit with the groove.
[0013] The utility model has the following beneficial effects:
[0014] 1. In the utility model, the stud is passed through the hole for installation and connection, and then the nut is put on, and then the inner hexagon is inserted into the inside of the hexagonal groove, and the stud and the nut can be gradually tightened, and then the cones on the outside of the two washers will pierce the outer layer of the equipment shell, which has an anti-slip effect and prevents the washer from vibrating and causing the cap head and the nut to shake. Finally, the anti-loosening nail is inserted into the inner side of the groove to achieve the effect of interference fit, so that the bolt installation is more stable and will not easily become loose.
[0015] 2. In the utility model, a hole with a smaller diameter is drilled by an electric drill, and then the tail end is inserted into the hole. The pointed cone block can be easily drilled into the hole, and the hole can be enlarged by rotating the blade to facilitate the screwing of the stud. Compared with directly opening a larger hole on the wooden board, it is more secure after installation and more labor-saving than directly inserting the stud into the hole of the wooden board.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Referring to Figures 1-3 , an embodiment provided by the present utility model: a bolt body with an anti-slip function, including a stud 1, a cap head 2 is fixedly connected to the top of the stud 1, a hexagonal groove 3 is opened at the top of the cap head 2, four grooves 4 are opened on the outer side of the stud 1, an anti-loosening pin 5 is slidably connected to the inner side of the groove 4, two washers 6 are sleeved on the outer side of the stud 1, a plurality of clamping cones 7 are fixedly connected to the outer side of the washers 6, a nut 8 is threadedly connected to the outside of the stud 1, a drilling component is arranged at the bottom of the stud 1, and the drilling component is used for the stud 1 to be conveniently inserted into the wooden board. After passing the stud 1 through the hole for installation connection and sleeving the nut 8, the two washers 6 are respectively on the inner and outer sides of the device. Then, insert an inner hexagon into the inside of the hexagonal groove 3, and the stud 1 and the nut 8 can be gradually tightened. Then, the clamping cones 7 on the outer sides of the two washers 6 will pierce into the outer layer of the device shell, playing an anti-slip effect, avoiding the washers 6 being driven by vibration to drive the cap head 2 and the nut 8 to shake. Finally, insert the anti-loosening pin 5 into the inner side of the groove 4, playing an interference fit effect, making the bolt installation more stable and not easily loosening
[0023] Referring to Figures 1-3 , the drilling component includes a tail end 9, the top of the tail end 9 is fixedly connected to the bottom of the stud 1, a plurality of pointed cone blocks 10 are fixedly connected to the outer side of the tail end 9, a plurality of blades 11 are fixedly connected to the outer side of the tail end 9 and are located above the pointed cone blocks 10. The bottom of the cap head 2 is slidably connected to the top of the upper washer 6, and the top of the nut 8 is slidably connected to the bottom of the lower washer 6. The two washers 6 are sleeved on the outside of the stud 1 in opposite directions, and the anti-loosening pin 5 and the groove 4 are in interference fit. When it is necessary to directly screw the stud 1 into the wooden board, drill a hole with a smaller diameter with an electric drill, and then insert the tail end 9 into the hole. The pointed cone blocks 10 can facilitate drilling into the hole, and rotating the blade 11 can enlarge the hole, facilitating the screwing of the stud 1. Compared with directly opening a larger hole, the installation is more firm, and it is more labor-saving than directly tightening the stud 1
[0024] Working principle: First, pass the stud 1 through the hole for installation connection, and then sleeve on the nut 8. The two washers 6 are respectively on the inner and outer sides of the device. By inserting an inner hexagon into the inside of the hexagonal groove 3, the stud 1 and the nut 8 can be gradually tightened. Then, the clamping cones 7 on the outer sides of the two washers 6 will pierce into the outer layer of the device shell, playing an anti-slip effect, avoiding the washers 6 being driven by vibration to drive the cap head 2 and the nut 8 to shake. Finally, insert the anti-loosening pin 5 into the inner side of the groove 4, playing an interference fit effect, making the bolt installation more stable and not easily loosening. In addition, when it is necessary to directly screw the stud 1 into the wooden board, drill a hole with a smaller diameter with an electric drill, and then insert the tail end 9 into the hole. The pointed cone blocks 10 can facilitate drilling into the hole, and rotating the blade 11 can enlarge the hole, facilitating the screwing of the stud 1. Compared with directly opening a larger hole, the installation is more firm, and it is more labor-saving than directly tightening the stud 1
