[0019] By setting airbags 7 on the clamping mechanism 2 and the pressing mechanism 3, and allowing the airbags 7 to contact the conductors on the insulator string, the conductors are positioned and locked in cooperation with the locking hooks 6. The airbags 7 also provide cushioning, which greatly reduces the problem of damage caused by severe friction due to continuous shaking of the conductors.
[0020] The clamping mechanism 2 includes a clamping block 201, a limiting rod 202, a limiting post 203, and a threaded spring 204. The limiting rod 202 is integrally formed and fixed to both sides of the clamping block 201. The positioning cap 1 has a square groove inside that corresponds to the limiting rod 202, and the square grooves are symmetrical to each other. The limiting rod 202 is slidably connected to the inside of the square groove. The limiting post 203 passes through the inside of the limiting rod 202, and both ends of the limiting post 203 are fixed to the inner surface of the square groove. The threaded spring 204 is sleeved on the outside of the limiting post 203, and both ends of the threaded spring 204 are fixed to the upper surface of the square groove and the limiting rod 202, respectively. A portion of the airbags 7 are fixed to the bottom of the clamping block 201, and all airbags 7 are made of rubber.
[0021] By setting up the clamping mechanism 2 and pressing down to make the airbag 7 contact the wire, the downward clamping of the wire is completed.

The fixing block 304 is fixed to both sides of the end of the pressure rod 302 away from the clamping block 301, and the inner surface of the rectangular groove is provided with a groove that matches the clamping block 301. The limiting post 305 passes through the inside of the clamping block 301, and both ends of the limiting post 305 are fixed to the inner side of the groove. Another part of the airbag 7 is fixed to the bottom surface of the clamping block 301.
[0023] By setting up the clamping mechanism 3, the conductor is further pressed down and clamped, making the conductor more stable.
[0024] The connecting groove 5 is connected to the rectangular groove; the push rod 303 is fixed to the top surfaces of both ends of the pressure rod 302, and the push rod 303 slides on the inner side of the connecting groove 5.
[0025] By setting the connecting groove 5, when the push rod 303 is pushed, it can then complete the extrusion at the other end.
[0026] The rubber pad 307 is fixed to the upper end of the push rod 303 and fits against the inner side of the connecting groove 5.
[0027] By setting a rubber gasket 307 to further seal the push rod 303, the sealing degree between the push rod 303 and the connecting groove 5 is improved.
[0028] The positioning mechanism 4 includes a setting groove 401, a positioning block 402, a fixing plate 403, a sliding rod 404, a base plate 405, and a return spring 406; the setting groove 401 is opened on both sides of the lower end of the positioning cap 1 and is connected to the connecting groove 5; the positioning block 402 is slidably connected inside the setting groove 401, and the ends of the positioning blocks 402 that are close to each other are set in a curved shape; the curved ends of the positioning blocks 402 are made of rubber.
[0029] By setting a positioning mechanism 4, the positioning mechanism 4 clamps the insulator string when the positioning cap 1 is closed, thereby improving the stability of the connection between the positioning cap 1 and the insulator string. By setting the positioning block 402 to have a curved end and using rubber material, the positioning block 402 can fit more closely to the insulator string.
[0030] The sliding rod 404 is fixedly connected to the side of the curved end of the positioning block 402 that is far apart from each other, and there are two sliding rods 404 that are symmetrical to each other; the positioning cap 1 has a through groove larger than the diameter of the sliding rod 404, and there are several through grooves that correspond to the sliding rod 404; the fixing plate 403 is fixedly connected to the inside of the through groove; the bottom plate 405 is slidably connected to the inside of the through groove; the end of the sliding rod 404 that is far away from the curved end of the positioning block 402 passes through the fixing plate 403 and is fixedly connected to the bottom plate 405; the return spring 406 is sleeved on the outside of the sliding rod 404, and the two ends of the return spring 406 are fixedly connected to the side of the bottom plate 405 and the fixing plate 403 that are close to each other.
[0031] By setting a reset spring 406, the positioning block 402 is reset after use, thus completing the separation of the positioning block 402 from the insulator string.
[0032] Working principle: When using, the worker first places the conductor that needs to be limited on the semi-circular groove at the top of the insulator. Then, the positioning cap 1 is placed on the insulator string, so that the conductor is covered inside the positioning cap 1. The positioning cap 1 is then pressed down, and the locking hook 6 on the outside of the positioning cap 1 comes into contact with the insulator string. Because the locking hook 6 has elastic deformation capability, the locking hook 6 will be opened by pressing it down, and it will continuously come into contact with the insulator string below until it stops pressing down. The locking hook 6 will then contact and engage with the edge of the insulator string through its rebound capability, thereby locking the positioning cap 1 on the edge of the insulator string and preventing the positioning cap 1 from falling off the insulator string. At the same time, when the positioning cap 1 is pressed down, the air bladder 7 on the clamping block 201 and the pressing block 301 will come into contact with the conductor on the insulator string. The soft air bladder 7 will come into contact with the conductor to reduce the problem of the conductor being damaged when it is pulled. Then the pressure will cause the clamping block 201 and the pressing block 301 to be subjected to an upward force. At this time, the clamping block 201 and the pressing block 301 will move upward until they fall to a certain range and cannot be pressed. When the positioning cap 1 cannot be pressed, the threaded spring 204 and the pressure spring 306 will push the cooperating pressure rod 302 and the limiting rod 202 respectively, so that the clamping block 201 and the pressing block 301 can press the wire more fully, thereby adapting to the irregular shape of the wire surface, making the airbag 7 on the clamping block 201 and the pressing block 301 more closely contact the wire, and reducing the problem of wire slippage; As the pressure rod 302 moves upward, it will also drive the fixed oil push rod 303 to move upward. When the oil push rod 303 moves, it will push the hydraulic oil inside the connecting groove 5, which will push the positioning block 402 to move, so that the positioning blocks 402 move closer to each other. As they move closer, the positioning blocks 402 will clamp the insulator string, making the contact between the positioning cap 1 and the insulator string more stable. When it is necessary to remove it, simply open the locking hook 6 and separate it from the surface of the insulator string. With continuous movement, the return spring 406 will pull the positioning block 402 back and separate it from the insulator string, thereby removing the positioning cap 1 from the surface of the insulator string and completing its convenient disassembly.
[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
