[0033] The two objects to be welded are placed in the mounting seat 4 respectively. At this time, the adjusting column 6 is rotated. As the threads on the outside of the adjusting column 6 contact the threads on the top of the mounting seat 4, the adjusting column 6 is moved downward. The connecting rods 5 on both sides of the top of the fixed arc plate 21 slide on the top of the mounting seat 4 to offset the rotational force generated by the adjusting column 6 on the fixed arc plate 21. At the same time, as the adjusting column 6 moves downward, the fixed arc plate 21 is pressed downward. As the fixed arc plate 21 continues to move downward, the upper support block 20 contacts the top of the object. As the fixed arc plate 21 is squeezed, the bottom support block 18 and the upper support block 20 simultaneously exert an extrusion force on the object, and the bottom stabilizing column 16 and the upper stabilizing column 19 respectively It fits on both sides of the object. As the surface of the object rises and falls, the bottom stabilizing column 16 and the upper stabilizing column 19 shrink inward, and the bottom spring 17 and the upper spring 22 apply thrust to the bottom stabilizing column 16 and the upper stabilizing column 19 respectively, so that the object is stably fixed inside the mounting seat 4. At this time, the adjusting handle 9 is rotated to drive the bidirectional threaded rod 10 to rotate, and the threads on the outside of the bidirectional threaded rod 10 contact the inside of the slider 11, so that the slider 11 is moved inward at the same time. The movement of the slider 11 drives the mounting seat 4 to move, so that the two objects are in contact for welding. Irregular shaped objects can also be stably fixed, which improves the versatility of the device clamping and enhances the stability of the clamping.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The exhaust collection assembly includes a collection tube 7, the inside of the collection tube 7 is slidably connected with a mesh frame 14, the inside of the mesh frame 14 is fixedly connected with an adsorption mesh plate 13, the top of the mesh frame 14 is fixedly connected with an extraction handle 2, the inner side of the extraction handle 2 is provided with a handle groove 15, the bottom end of the collection tube 7 is fixedly connected with an exhaust fan 12, the inner side of the collection tube 7 is fixedly connected to the outside of the two sides of the supporting main body plate 1, the inner side of the collection tube 7 is respectively fixedly connected to the outer side of the installation limit plate 8, and the bottom end of the extraction handle 2 is respectively correspondingly attached to the top of the collection tube 7;

[0035] As the welding work proceeds, the debris on the surface of the object falls on the top of the supporting body plate 1 due to high-temperature carbonization. At this time, the exhaust fans 12 on both sides are started to quickly transport the air inside the collection pipe 7 to the outside. At this time, the top notch of the collection pipe 7 generates suction due to the rapid downward outflow of internal air, and the debris falling on the top of the supporting body plate 1 is sucked into the inside of the device. The debris moves inside the collection pipe 7 with the suction force, and the debris contacts the inner side of the mesh frame 14 and is adhered by the adsorption mesh plate 13, so that the debris is restricted to the surface of the adsorption mesh plate 13. At the same time, the external air quickly enters the interior through the hole groove of the upper collection pipe 7, and the air near the collection pipe 7 flows faster, which can speed up the cooling of the welding point and improve the welding efficiency. After the welding is completed, the extraction handle 2 is pulled upward through the handle groove 15, so as to remove the mesh frame 14 and clean the adsorption mesh plate 13. After completion, it can be reinserted to continue working. The debris can be collected in real time to reduce the accumulation of debris, which is more convenient for later processing and provides convenience for cleaning.

[0036] Working principle: put the two objects to be welded into the mounting seat 4 respectively, and then rotate the adjusting column 6. As the outer thread of the adjusting column 6 contacts the thread at the top of the mounting seat 4, the adjusting column 6 moves downward, and at the same time, as the adjusting column 6 moves downward, the fixed arc plate 21 is pressed downward. As the fixed arc plate 21 continues to move downward, the upper support block 20 contacts the top of the object. As the fixed arc plate 21 is squeezed, the bottom support block 18 and the upper support block 20 simultaneously exert an extrusion force on the object, and the bottom stabilizing column 16 and the upper stabilizing column 19 are respectively attached to the two sides of the object. As the surface of the object rises and falls, the bottom stabilizing column 16 and the upper stabilizing column 19 shrink inward, and the bottom spring 17 and the upper spring 22 respectively apply thrust to the bottom stabilizing column 16 and the upper stabilizing column 19, thereby stably fixing the object inside the mounting seat 4. At this time, rotating the adjusting handle 9 drives the bidirectional threaded rod 10 to rotate, and through The threads on the outside of the two-way threaded rod 10 contact the inside of the slider 11, and the slider 11 is moved inward at the same time. The movement of the slider 11 drives the mounting seat 4 to move, so that the two objects are in contact and welding is carried out. As the welding work proceeds, the debris on the surface of the object falls on the top of the supporting main body plate 1 due to high-temperature carbonization. At this time, the exhaust fans 12 on both sides are started to quickly transport the air inside the collecting pipe 7 to the outside. At this time, the top notch of the collecting pipe 7 generates suction due to the rapid downward outflow of internal air, and the debris dropped on the top of the supporting main body plate 1 is sucked into the inside of the device. The debris moves inside the collecting pipe 7 with the suction force, and the debris contacts the inner side of the mesh frame 14 and is adhered to the adsorption mesh plate 13, limiting the debris to the surface of the adsorption mesh plate 13. After welding is completed, the extraction handle 2 is pulled upward through the handle groove 15, so as to remove the mesh frame 14 and clean the adsorption mesh plate 13. After completion, it can be reinserted to continue working.
