At the same time, the middle part of the elastic member 14 is pulled to deform during the lifting process. When the end of the bayonet 18 is separated from the first top block 17, the first connecting plate 16 can be reset again under the action of the resetting tension of the elastic member 14 until the bayonet 18 is stuck in the specified position, and it can be fixed by means of the plane of the first top block 17 and the other end of the bayonet 18. At the same time, when it is necessary to remove the male connector 1 and the female connector 12, the staff can pull the first connecting plate 16 upward in sequence to make The first top block 17 is separated from the bayonet pin 18, and then the male connector 1 and the female connector 12 can be separated by pulling. This step cooperates with the first connecting plate 16 and the bayonet pin 18 to fix the male connector 1 and the female connector 12, thereby reducing the problem that when the staff uses the welding tool, the male connector 1 and the female connector 12 become loose or separated due to continuous pulling to adjust the welding angle, thereby affecting the normal operation of the welding device. The arc surface between the first top block 17 and the bayonet pin 18 can increase the speed of clamping the bayonet pin 18 inside the clamp 13.

[0026] like Figure 1 and 4As shown, the end of the male connector 1 is fixedly connected to a bracket 2; the end of the bracket 2 is fixedly connected to a frame 21; a slide groove 22 is opened in the middle of the frame 21; the inner wall of the slide groove 22 is slidably connected to a slider 23; the connecting wire 11 is slidably arranged inside the slider 23; two groups of elastic ropes 24 are fixedly connected to the side wall of the slider 23, and the other end of the elastic rope 24 is fixedly connected to the inner wall of the frame 21; when working, by providing the bracket 2 at the end of the male connector 1, the end of the connecting wire 11 can be stuck in the slider 23, so that when the staff pulls the connecting wire 11, the connecting wire 11 will be offset and at the same time in the slider 23 The slider 23 is subjected to a force and moves on the inner wall of the slide groove 22. During the movement, one of the two sets of elastic ropes 24 will be pulled and react, and the slider 23 is continuously pulled toward the middle of the frame 21, and this is repeated. In this step, a slidable slider 23 is provided on the inner wall of the frame 21, so that the problem of the connection line 11 being broken or damaged at the connection between the connection line 11 and the male connector 1 due to a large bending amplitude during operation can be reduced, thereby improving the overall use cycle, and using the tension generated by the elastic rope 24 to continuously reset the slider 23 toward the middle of the frame 21.

By providing a spring column 3 at the end of the latch 18, when the latch 13 gradually moves toward the output end of the spring column 3, the support block 32 provided at the bottom thereof will gradually contact the second top block 31, and after continued pushing, the output end of the spring column 3 will be retracted toward the inside thereof. When the male connector 1 and the female connector 12 need to be separated later, the male connector 1 can be ejected toward the outside with the help of the output end of the spring column 3, and by providing a second The connecting plate 4 allows the staff to only pull the second connecting plate 4 upward when they need to pull the two groups of first connecting plates 16 upward, and the scraper 41 at the bottom of the second connecting plate 4 will clean up the impurities at the output end of the male connector 1. By providing a groove 51 in the middle of the support block 32, when the second top block 31 is close to the support block 32, the friction pad 5 in the middle will be stuck in the groove 51. By providing a soft pad 6 on the inner wall of the slider 23, when the connecting line 11 slides on the inner wall of the slider 23, the surface of the connecting line 11 will contact the soft pad 6. By providing a friction pattern 7 in the middle of the second connecting plate 4, when the staff's hand contacts the second connecting plate 4, its hand will first contact the friction pattern 7.
