The telescopic rod 7 and the protective sleeve 10 are connected by direct insertion. At the groove of the connecting frame 8, there is a connecting plate 9. The connecting frame 8 and the connecting plate 9 are connected.

[0024] Embodiment 2

[0025] When using the present utility model, first install the fixed seat 1 of the welding tooling for manufacturing metal shells at the required position. If the welding tooling for manufacturing metal shells is to be fixed on the wall, fix the cover plate 5 and the connecting frame 8 on one side, and do not connect the cover plate 5 on the other side first. Determine whether the shape of the metal shell to be welded is circular or square. If the metal shell to be welded is square, install the connecting plate 9 in the square groove of the connecting frame 8 and fix it by a buckle. When using the present utility model, there is no requirement for the metal shell to have a bottom surface and a top surface, or it can be without them. When it is without them, after the installation is completed, put the metal shell into the interior of the welding tooling, judge the position to be welded, take out the connecting plate 9 at the position to be welded. At this time, the welding interface is exposed. Adjust the telescopic frame 3 on the side where the cover plate 5 is not connected to the connecting frame 8, fix the support column 6 to the cover plate 5, and fix the groove of the cover plate 5 to the convex block of the connecting frame 8 by adjusting the telescopic frame 3. Press the protective sleeve 10 against the interior of the metal shell by controlling the telescopic distance of the telescopic rod 7. If there is more than one position to be welded, the position to be welded can be rotated to a position convenient for operation by the rotating block 4 to complete the welding of the position to be welded on the metal shell. After the welding is completed, wait until the surface is not sticky, then flip the welding tooling for manufacturing metal shells, open the cover plate 5 on the other side where the support column 6 is not connected through the lifting frame, put the connecting plate 9 back to its original position, cover the cover plate 5, and take out the metal shell after the welded part of the metal shell is fully fixed. If the metal shell has a top surface and a bottom surface, when welding, first weld the side surface. After the side surface welding is completed, flip the welding tooling for manufacturing metal shells, open the cover plate 5 on the other side where the support column 6 is not connected through the lifting frame, and weld one of the top surface or the bottom surface. At this time, the support column 6 is inside. After the welded part of the metal shell is fully fixed, continue to flip the welding tooling for manufacturing metal shells, open the cover plate 5 connected to the support column 6 through the lifting frame, remove the support column 6, weld the other surface, and wait until the surface is not sticky, then close the cover plate 5 until the welded part is fully fixed.

[0026] Embodiment 3

[0027] If the metal shell to be welded is circular, it is only necessary to install the connecting plate 9 on the circular groove of the connecting frame 8, put the metal shell into the welding tool, determine the position to be welded, and take out the connecting plate 9 at the position to be welded. At this time, the welding port leaks out, and adjust the telescopic frame 3 that does not connect the cover plate 5 to the side of the connecting frame 8, fix the support column 6 to the cover plate 5, and fix the groove of the cover plate 5 to the protrusion of the connecting frame 8 by adjusting the telescopic frame 3. The protective cover 10 is pressed against the inside of the metal shell by controlling the telescopic distance of the telescopic rod 7. If more than one place needs to be welded, the position to be welded can be rotated to a position convenient for operation by rotating the block 4 to complete the welding of the metal shell at the position where it needs to be welded. After the welding is completed, when the surface position is no longer sticky, turn over the welding tool for metal shell manufacturing, open the cover plate 5 on the other side that is not connected to the support column 6 through the lifting frame, put the connecting plate 9 back to its original position, cover the cover plate 5, and take out the metal shell after the welding part of the metal shell is fully fixed. If the metal shell contains a top surface and a bottom surface, weld the side surface first. After the side welding is completed, turn over the welding tool for metal shell manufacturing, open the cover plate 5 on the other side that is not connected to the support column 6 through the lifting frame, and weld one of the top or bottom surfaces. At this time, the support column 6 is inside. After the welding part of the metal shell is fully fixed, continue to turn over the welding tool for metal shell manufacturing, open the cover plate 5 connected to the support column 6 through the lifting frame, remove the support column 6, weld the other surface, and close the cover plate 5 until the welding position is fully fixed.
