[0021] Example 2, distinguishing features from Example 1: such as Figures 4-12The moving component 4 includes an electrode base 411 fixedly connected to the surface of the electrode handle 1; a water storage box 401 fixedly connected to the bottom of the connecting plate 306; a sliding tube 403 fixedly connected to the surface of the water storage box 401; a pad 402 fixedly connected to the inner wall surface of the sliding tube 403; a top tube 407 slidably connected to the surface of the sliding tube 403; and an insertion hole 412 formed on the surface of the water storage box 401. The moving component 4 also includes a sliding hole 404 located at the bottom of the top tube 407, and an insertion hole 412 formed on the surface of the top tube 407. A water outlet 406 is provided. A limiting block 405 is fixedly connected to one end of the top pipe 407 away from the water outlet 406. A connecting hole 408 is opened on the surface of the electrode base 411, and the connecting hole 408 is fixedly connected to one end of the connecting pipe 302. A limiting plate 409 is fixedly connected to the inner wall surface of the electrode base 411. A cooling component 5 is provided on the surface of the limiting plate 409. A water outlet groove 410 is opened on the inner wall surface of the electrode cover 311, and the water outlet groove 410 is connected to the bottom of the outlet pipe 307. Compressed air enters from the connecting sleeve 305. After the water storage box 401 is pushed outward, the cold water inside the water storage box 401 receives pressure and pushes the jacking pipe 407 outward from the surface of the through hole until it stops when the limiting block 405 abuts against the inner wall of the through hole. Before the compressed air is injected, the water storage plate 504 is fixed to the water storage box 401 through the connection between the insert block 505 and the insertion hole 412. The water flowing out of the water storage box 401 flows into the water storage ball 512 through the air plate 510 and is absorbed and stored inside the water storage ball 512. At the same time as the jacking pipe 407 is pushed outward, the water storage plate 504 is pushed outward through the sliding rod 50. The sliding of the surface pushes the water storage plate 504 toward the limiting plate 409. The water storage ball 512 is squeezed by the inner wall of the electrode cover 311, releasing the cold water inside into the inner wall of the electrode cover 311. The cold water is discharged outward through the moving pipe 308. At the same time as the water storage plate 504 is pushed outward, the impact block 502 collides with the impact ring 517. By squeezing the impact ring 517, the water inside the water storage plate 504 is sprayed outward through the impact pipe 509, which can effectively cool the inside of the electrode assembly and the electrode covers 311 at both ends.

[0022] Example 3, distinguishing features from Example 1: such as Figures 7-12The cooling component 5 includes a slide rod 501, which is fixedly connected to the surface of the limiting plate 409. An impact block 502 is fixedly connected to the surface of the slide rod 501. A water storage plate 504 is slidably connected to the surface of the slide rod 501. A countersunk hole 507 is formed on the surface of the water storage plate 504, and the countersunk hole 507 contacts the surface of the slide rod 501. A connecting box 508 is fixedly connected to the surface of the water storage plate 504. An impact tube 509 is fixedly connected to the end of the connecting box 508 away from the water storage plate 504. A cover plate 506 is fixedly connected to the surface of the water storage plate 504. An insert block 505 is fixedly connected to the end of the cover plate 506 away from the water storage plate 504. It also includes a wind plate 510, which is fixedly connected to the surface of the water storage plate 504. An impact pad 511 is fixedly connected to the end of the wind plate 510 away from the water storage plate 504, and a water storage ball 512 is fixedly connected to the end of the impact pad 511 away from the wind plate 510. The number of water storage balls 512 is set to two, and the two water storage balls 512 are symmetrically installed on the surface of the impact pad 511 with the center line of the water storage box 401 as the axis of symmetry. Impact rings 517 are slidably connected to both sides of the inner wall of the countersunk hole 507. A connecting shaft 515 is fixedly connected to the inner wall surface of the electrode handle 1, and a rotating sleeve 514 is rotatably connected to the surface of the connecting shaft 515. The number of rotating sleeves 514 is set to... Two rotating sleeves 514 are symmetrically arranged on the inner wall surface of the electrode grip 1 about the center line of the limiting plate 409. A rotating plate 513 is fixedly connected to the surface of each rotating sleeve 514. An airflow groove 516 is formed on the surface of the rotating plate 513. Four airflow plates 503 are fixedly connected to the inner wall surface of the electrode grip 1. These four airflow plates 503 are symmetrically arranged on both sides of the inner wall of the electrode grip 1 about the center line of the limiting plate 409. Compressed air enters the blowing pipe 304 from the connecting pipe 302 and is discharged outwards. The discharged airflow blows onto the rotating plate 513, causing it to rotate. As the rotating plate 513 rotates, it generates airflow that blows into the electrode assembly, drying the interior of the electrode assembly that has been wetted by cold water. It also discharges the heat inside the electrode assembly outward through the gaps in the electrode plate 2. When the rotating plate 513 rotates, the airflow generated flows into the inner wall of the electrode cover 311 through the surface of the airflow plate 503, drying the inner wall of the electrode cover 311 that has been wetted by cold water, and discharging the heat inside outward through the outlet pipe 307. This solves the problem that the water droplets inside the electrode assembly cannot be effectively dried after it has been cooled by cold water, thus preventing leakage of electricity due to water condensation inside the electrode assembly after it is connected to the current.

[0023] Working principle: Compressed air enters the air blowing pipe 304 from the connecting pipe 302 and is discharged outwards. The discharged airflow blows onto the rotating plate 513, causing it to rotate. As the rotating plate 513 rotates, it generates airflow that blows into the electrode assembly, drying the interior of the electrode assembly after it has been wetted by cold water. The heat inside the electrode assembly is also discharged outwards through the gaps in the electrode plate 2. The airflow generated by the rotating plate 513 flows through the surface of the airflow plate 503 into the inner wall of the electrode cover 311, further drying the interior of the electrode cover 311 after it has been wetted by cold water. The wall is dried by blowing air, and the internal heat is discharged to the outside through the outlet pipe 307. This solves the problem that the water droplets inside the electrode assembly cannot be effectively dried after being cooled by cold water. Compressed air is injected into the inlet pipe 301 by an air compressor. The air enters the connecting pipe 302 through the connecting sleeve 305, and then enters the annular plate 310 through the moving pipe 308 and is blown out through the air outlet 309. After spot welding, the welding slag will adhere to the nut. The compressed welding slag on the nut can be cleaned. The compressed air enters from the connecting sleeve... After 305 enters the water storage box 401, the cold water inside the water storage box 401 receives pressure and pushes the jacking pipe 407 outward from the surface of the through hole until it stops when the limiting block 405 abuts against the inner wall of the through hole. Before the compressed air is injected, the water storage plate 504 is fixed to the water storage box 401 through the connection between the insert block 505 and the insertion hole 412. The water flowing out of the water storage box 401 flows from the air plate 510 into the water storage ball 512 and is absorbed and stored inside the water storage ball 512. At the same time as the jacking pipe 407 is pushed outward, the water storage plate 504 is pushed outward through the sliding block 405. The sliding of the surface of rod 501 pushes the water storage plate 504 toward the limiting plate 409. The water storage ball 512 is squeezed by the inner wall of the electrode cover 311, releasing the cold water inside into the inner wall of the electrode cover 311. The cold water is then discharged outward through the moving pipe 308. At the same time as the water storage plate 504 is pushed outward, the impact block 502 collides with the impact ring 517. By squeezing the impact ring 517, the water inside the water storage plate 504 is sprayed outward through the impact pipe 509, which can effectively cool the inside of the electrode assembly and the electrode covers 311 at both ends.
