[0043] Working principle: During operation, when the heat exchanger needs to be welded and assembled, the outer wall of the heat exchanger can be placed inside the anti-slip groove 2, and then the heat exchange tube can be fixed to the clamping assembly, and then the position of the clamping assembly can be adjusted by the adjusting assembly. When the adjusting assembly is adjusted, the rotating rod 7 can be pulled to make the fixing rod 6 disengage from the fixing groove 10, and then the rotating rod 7 can be rotated. When it is rotated to the corresponding position, the rotating rod 7 can be loosened to make the first spring 9 push the first positioning block 8, and then the fixing rod 6 is inserted into the inside of the fixing groove 10, and then the heat exchanger can be welded and fixed, thereby realizing the function of reducing the labor of operators during the welding process, and effectively solving the problem of consuming manpower and material resources when supporting the heat exchange tube by manpower.

[0044] When the position of the clamping assembly needs to be adjusted, the handle 13 can be rotated to drive the screw rod 12 to rotate.

[0045] When the heat exchange tube needs to be clamped, the heat exchange tube can be placed inside the clamping groove, and then the threaded rod 15 is rotated so that the threaded rod 15 drives the first clamping jaw 17 to press downward, thereby clamping the heat exchange tube through the first clamping pad 18. When the threaded rod 15 moves downward, it pushes the second clamping jaw 19, so that the second clamping jaw 19 rotates and drives the second clamping pad 20 to clamp the heat exchange tube, thereby stably fixing the heat exchange tube inside the clamping groove, making the welding and installation of the heat exchanger more convenient.

[0046] When the adjusting arm 11 rotates, the mutual engagement between the second positioning block 22 and the second positioning groove can make the adjusting arm 11 more stable during rotation. At the same time, the roller 23 can convert the sliding friction between the second positioning block 22 and the second positioning groove into rolling friction, thereby reducing the wear between the second positioning block 22 and the second positioning groove and increasing the service life of the device.

[0047] When the first clamping pad 18 and the second clamping pad 20 clamp the heat exchange tube, the air inside the first adsorption groove 24 and the second adsorption groove 25 can be squeezed out, and then the heat exchange tube is adsorbed and fixed by the first adsorption groove 24 and the second adsorption groove 25, so that the first clamping pad 18 and the second clamping pad 20 clamp the heat exchange tube more stably.

[0048] When the first clamping pad 18 and the second clamping pad 20 clamp the heat exchange tube, the space between the second adsorption groove 25 and the first adsorption groove 24 can be expanded by pulling the first vacuum block 26 and the second vacuum block 28, so that the adsorption capacity of the second adsorption groove 25 and the first adsorption groove 24 can be stronger, thereby making the first clamping pad 18 and the second clamping pad 20 have a better fixing effect on the heat exchange tube.

[0049] When the synchronization rod 16 presses the second jaw 19, the anti-wear wheel 32 can rotate, thereby reducing the friction and wear between the synchronization rod 16 and the second jaw 19; when the second jaw 19 is tightened and fixed, the ratchet can make it difficult for the anti-wear wheel 32 to rotate, thereby making it difficult for the second jaw 19 to shake.

[0050] When the fixing rod 6 extends into the fixing groove 10 , the first anti-slip pad 33 can increase the contact area between the fixing rod 6 and the fixing groove 10 , thereby increasing the friction between the fixing rod 6 and the fixing groove 10 , thereby increasing the fixing ability of the fixing groove 10 to the fixing rod 6 .
