[0022] The first handle 4 and the second handle 42 are fixedly provided on the top of the second clamping frame 21 and the fourth clamping frame 24 , respectively. The sleeve 41 and the grip 43 are fixedly provided on the top of the first handle 4 and the second handle 42 , respectively.

[0023] The first pipe fitting 3 is clamped and fixed between the first clamping frame 2 and the second clamping frame 21, and the second pipe fitting 31 is clamped and fixed between the third clamping frame 23 and the fourth clamping frame 24. By pulling the second handle 42 and the first handle 4 upward, the fourth clamping frame 24 and the second clamping frame 21 can be respectively driven to move upward. At this time, the second pipe fitting 31 and the first pipe fitting 3 can be placed on the top of the third clamping frame 23 and the first clamping frame 2 respectively. After loosening the second handle 42 and the first handle 4, the fourth clamping frame 24 and the second clamping frame 21 can be respectively driven to move downward by the resilience of the second spring telescopic rod 25 and the first spring telescopic rod 22 to clamp and fix the second pipe fitting 31 and the first pipe fitting 3.

[0024] The outer wall of the first clamping frame 2 is fixedly provided with a guide rail 1, and the third clamping frame 23 is slidably arranged inside the guide rail 1. A mounting hole is provided on the left side of the first clamping frame 2, and a screw 11 is rotatably arranged in the mounting hole. A threaded hole is penetrated on the left side of the third clamping frame 23, and the screw 11 is screwed in the threaded hole. The left side of the screw 11 penetrates the left side of the guide rail 1 and is connected with a worm gear 12. A worm 13 is meshed at the bottom of the worm gear 12, and a hand wheel 14 is fixedly provided on the front side of the worm gear 13. Turning the hand wheel 14 drives the worm gear 12 to rotate through the worm 13, and then drives the screw 11 to rotate. When the screw 11 rotates, it drives the third clamping frame 23 to move to the right, and then drives the second pipe 31 and the handle 43 to move to the right. When the part 31 moves to the right, it will dock with the first pipe fitting 3, and when the handle 43 moves to the right, it will be inserted into the inside of the sleeve 41. At this time, the welding gun can be used to weld the joint between the second pipe fitting 31 and the first pipe fitting 3, and pulling the handle 43 upward can drive the sleeve 41 connected with the handle 43 to move upward synchronously. At this time, the fourth clamping frame 24 and the second clamping frame 21 can be driven to move upward synchronously, and then the welded first pipe fitting 3 and the second pipe fitting 31 can be rotated, so that the joint between the first pipe fitting 3 and the second pipe fitting 31 can be annularly welded, thereby improving the convenience of welding, and the outer wall of the worm 13 is evenly rotated to set two sets of rotating shaft seats, and the two sets of rotating shaft seats are evenly fixed on the left side of the guide rail 1.

[0025] Working principle: Pulling the second handle 42 and the first handle 4 upwards can respectively drive the fourth clamping frame 24 and the second clamping frame 21 to move upwards, at which time the second pipe 31 and the first pipe 3 can be placed on the top of the third clamping frame 23 and the first clamping frame 2 respectively. After loosening the second handle 42 and the first handle 4, the second spring telescopic rod 25 and the first spring telescopic rod 22 can respectively drive the fourth clamping frame 24 and the second clamping frame 21 to move downwards to clamp and fix the second pipe 31 and the first pipe 3. Turning the handwheel 14 drives the worm wheel 12 to rotate through the worm 13, and then drives the screw 11 to rotate. When the screw 11 rotates, it will drive the third clamping frame 23 to move upwards. The second pipe fitting 31 and the handle 43 move rightward, thereby driving the second pipe fitting 31 and the handle 43 to move rightward. When the second pipe fitting 31 moves rightward, it will dock with the first pipe fitting 3. When the handle 43 moves rightward, it will be inserted into the inside of the sleeve 41. At this time, a welding gun can be used to weld the docking point between the second pipe fitting 31 and the first pipe fitting 3. Pulling the handle 43 upward can drive the sleeve 41 that is sleeved with the handle 43 to move upward synchronously. At this time, the fourth clamping frame 24 and the second clamping frame 21 can be driven to move upward synchronously. Then, the welded first pipe fitting 3 and the second pipe fitting 31 can be rotated, so that the docking point between the first pipe fitting 3 and the second pipe fitting 31 can be annularly welded, thereby improving the convenience of welding.
