[0005] The anti-recoil mechanism includes a connecting block and two anti-recoil blocks, air holes begin to be formed on both sides of the upper end of the connecting block, second air grooves begin to be formed on both sides of the connecting block, a second support rod is fixedly provided on the side away from each other of the two anti-recoil blocks, and a second piston is fixedly provided on the side away from each other of the two second support rods.

[0006] Furthermore, the connecting block is fixedly arranged at the lower end of the nut, and the two first pistons are slidably arranged inside the two first air grooves respectively.

[0007] Furthermore, the two first support rods are respectively fixedly arranged on both sides of the lower end of the support plate.

[0008] Furthermore, the two air holes are connected to the two first air grooves respectively.

[0009] Furthermore, the rubber pad is fixedly arranged on the upper end of the supporting plate.

[0010] Furthermore, placement grooves are provided on both sides of the interior of the connection block.

[0011] Furthermore, the two second pistons are slidably disposed inside the two second air grooves respectively.

[0012] By adopting the above structure, the nut is squeezed by the bolt, and then the support plate on the extrusion mechanism pushes the gas inside the first air groove to move through the first piston, so that the gas passes through the air hole into the second air groove, and then the second piston inside the second air groove is pushed by the gas to move, and the second piston squeezes the bolt through the stop block, thereby clamping the bolt.

[0013] In summary, the beneficial effect of the utility model is that the bolt is squeezed by the extrusion mechanism and then pushed by gas, thereby driving the second piston to move, so that the second piston moves through the stop block on the second support rod, which is convenient for clamping the bolt through the stop block, saving time and effort and improving work efficiency. At the same time, when the bolt squeezes the nut, a certain elastic support can be provided by connecting the spring and the rubber pad, so that the connection between the bolt and the nut is more firm and the impact of vibration is reduced.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6 As shown, the utility model provides a back-stopping and anti-loosening nut, comprising: a main body 1, an extrusion mechanism 2 is arranged at the upper end of the main body 1, which is convenient for receiving the extrusion of the bolt, and a back-stopping mechanism 3 is arranged at the lower end of the main body 1, which is convenient for clamping the bolt, thereby preventing the bolt from becoming loose during use. The main body 1 comprises a nut 101, and first air grooves 102 are penetrated on both sides of the interior of the nut 101, and the extrusion mechanism 2 comprises a support plate 201, a first support rod 204 and a rubber pad 202, and the lower ends of the two first support rods 204 are fixedly provided with a first piston 205, The first piston 205 facilitates the pushing of gas to move, and the first gas groove 102 facilitates the stable movement of the first piston 205. A connecting spring 203 is fixedly connected between the nut 101 and the support plate 201 near the first support rod 204. The connecting spring 203 facilitates the provision of a certain elastic support, so that the connection between the bolt and the nut 101 is more secure. At the same time, when the device is not in use, the connecting spring 203 facilitates the reset, preventing the piston from being in use during use and affecting subsequent use, thereby improving work efficiency to a certain extent.

[0025] The anti-recoil mechanism 3 includes a connecting block 301 and two anti-recoil blocks 304. The anti-recoil blocks 304 can be made of rubber. The anti-recoil blocks 304 are used to squeeze the bolts to prevent the bolts from becoming loose after use, thereby achieving the purpose of anti-recoil. The connecting block 301 has air holes 302 on both sides of the upper end. The air holes 302 are arranged on both sides of the second air groove 307, which can allow gas to move and facilitate the gas to push the piston to move. The connecting block 301 has second air grooves 307 on both sides of the interior to facilitate stable movement of the piston. The two anti-recoil blocks 304 are fixedly provided with a second support rod 305 on the side away from each other to facilitate supporting the anti-recoil blocks 304. The two second support rods 305 are fixedly provided with a second piston 306 on the side away from each other to facilitate receiving gas push, so that the anti-recoil blocks 304 clamp the bolts.

[0026] Furthermore, the connecting block 301 is fixedly arranged at the lower end of the nut 101, so that when the bolt is about to be installed, the anti-recognition mechanism 3 on the nut 101 is squeezed, and then the anti-recognition block 304 is pushed to move by the piston, and then the bolt is clamped by the anti-recognition block 304 to prevent the bolt from becoming loose. The two first pistons 205 are respectively slidably arranged inside the two first air grooves 102, so that the pistons can move stably inside the air grooves.

[0027] Furthermore, the two first support rods 204 are fixedly arranged on both sides of the lower end of the support plate 201 respectively.

[0028] Furthermore, the two air holes 302 are connected to the two first air grooves 102 respectively, and the gas passes through the first air grooves 102 and enters into the second air groove 307 through the air holes 302, so that the stop block 304 can be pushed to move by the gas.

[0029] Furthermore, the rubber pad 202 is fixedly arranged on the upper end of the support plate 201. When the nut is squeezed, the contact area between the nut 101 and the bolt is increased, thereby increasing the friction force, which can prevent the bolt and the nut 101 from loosening during vibration.

[0030] Furthermore, placement grooves 303 are provided on both sides of the interior of the connection block 301 . When the device is used, the placement grooves 303 facilitate the placement of the stop block 304 .

[0031] Furthermore, the two second pistons 306 are slidably disposed inside the two second air grooves 307 , respectively.

[0032] By adopting the above structure, the nut is squeezed by the bolt, and then the support plate 201 on the extrusion mechanism 2 pushes the gas inside the first air groove 102 to move through the first piston 205, so that the gas passes through the air hole 302 and enters the second air groove 307, and then the second piston 306 inside the second air groove 307 is pushed by the gas to move, and the second piston 306 squeezes the bolt through the stop block 304, thereby clamping the bolt.
