[0052] When welding, the first electric push rod 1 drives the moving seat 306 to move, so that one end of the mouth pipe 4 is in contact with one side of the connecting head 6, and the cover plate 502 is in contact with the opening on one side of the shell 507, and when welding, if flying impurities are generated, the flying impurities can be splashed on the surfaces of the first partition plate 504 and the second partition plate 505, so that the first partition plate 504 and the second partition plate 505 can be replaced after long-time use;

[0055] When the welding process produces spatter, the spatter adheres to the surfaces of the first baffle 504 and the second baffle 505. Since the first baffle 504 and the second baffle 505 are both inclined, if the molten impurities flow, they will flow along the surfaces of the first baffle 504 and the second baffle 505, thereby reducing the possibility of the molten impurities directly falling on the surface of the harmonica tube 4.

[0061] Specifically, when welding, the first electric push rod 1 pushes the moving seat 306 to move so that one end of the harmonica tube 4 contacts the connector 6, then the second electric push rod 301 pushes the first push plate 302 to move, and the first spring 304 is gradually compressed under the pushing of the first push plate 302, so that the extrusion force between the harmonica tube 4 and the connector 6 gradually increases;

[0068] When the extruding rod 307 pushes the second connecting seat 706 to move, the connecting rod 705 is driven to move, and the connecting frame 712 can drive the push rod 708 to swing, and the third refrigerating plate 711 is driven to swing through the connecting shaft 709.

[0069] Specific embodiments are: when welding, with the movement of the moving seat 306, the extrusion rod 307 can be moved, and when the cover plate 502 is in contact with the shell 507, the extrusion rod 307 can push the second connecting seat 706 to move to the other end, and in the process of moving the second connecting seat 706, the connection plate 703 can be moved outward by the extrusion of the connecting rod 705, and the second refrigeration plate 702 is moved outward, so that the second refrigeration plate 702 is separated from the connecting head 6;

[0070] At the same time, the movement of the second connecting seat 706 can drive the connecting frame 712 to move through the connecting rod 705, and because the cylinder at the top of the connecting frame 712 is located inside the lever 708, the connecting frame 712 can drive the lever 708 to swing, thereby driving the fixed disc 710 and the connecting shaft 709 to rotate, so that the third refrigeration plate 711 is separated from the top surface of the connecting head 6, thereby avoiding the second refrigeration plate 702 and the third refrigeration plate 711 from being in contact with the connecting head 6 during welding;

[0071] And if spatter occurs during welding, the impurities can be quickly cooled by the first refrigeration plate 701, so that the impurities in the molten state are quickly cooled, thereby reducing the flowability of the impurities and further avoiding the impurities from falling on the surface of the harmonica tube 4;

[0072] At the same time, after the welding is completed, the connecting rod 705 can be reset by the second spring 707, thereby pushing the connection plate 703 and the second refrigeration plate 702 to move, and making the second refrigeration plate 702 in contact with the connecting head 6, and the connecting frame 712 can drive the lever 708 to reset, thereby making the third refrigeration plate 711 re-contact with the top end of the connecting head 6, and then the connecting head 6 is quickly cooled by the second refrigeration plate 702 and the third refrigeration plate 711.

[0073] Working principle: when welding, the connecting head 6 is placed inside the shell 507, the harmonica tube 4 is placed on the top surface of the moving seat 306, the cover plate 502 is inserted from one side and fixed by the fixed pin 501, then the moving seat 306 is moved by the first electric push rod 1, so that one end of the harmonica tube 4 is in contact with the connecting head 6:

[0074] With the movement of the moving base 306, the extrusion rod 307 can be moved, and when the cover plate 502 is in contact with the shell 507, the extrusion rod 307 can push the second connecting base 706 to move to the other end, and in the process of moving the second connecting base 706, the connection plate 703 can be extruded by the connecting rod 705 to move outward, and the second refrigeration plate 702 is moved outward to separate the second refrigeration plate 702 from the connecting head 6;

[0076] Then the first push plate 302 can be moved by the second electric push rod 301, and under the pushing of the first push plate 302, the first spring 304 is gradually compressed, so that the extrusion force between the harmonica tube 4 and the connecting head 6 is gradually increased;

[0077] Meanwhile, the movement of the first push plate 302 can make the push rod 303 gradually contact the second push plate 305, and when the push rod 303 contacts the second push plate 305, it can ensure that the pushing force of the second electric push rod 301 is fully applied to the harmonica tube 4, so that the harmonica tube 4 can be in close contact with the connecting head 6, and at this time, one side of the cover plate 502 is in close contact with the shell 507, so that the current is passed through the contact between one end of the harmonica tube 4 and one side of the connecting head 6 to weld;

[0078] During the welding process, if spatter occurs, the spatter impurities will adhere to the surface of the first baffle 504 and the second baffle 505, and because the first baffle 504 and the second baffle 505 are both inclined, if the molten impurities flow, they will flow along the surface of the first baffle 504 and the second baffle 505, thereby reducing the possibility of molten impurities directly falling on the surface of the harmonica tube 4;

[0079] And the material receiving strip 503 at the bottom end of the first baffle 504 can prevent impurities from sliding off the bottom end of the first baffle 504, and the blocking strip 513 on one side of the cover plate 502 can also prevent the impurities on the surface of the cover plate 502 from flowing to the surface of the harmonica tube 4;
