[0018] Figure 1 It is a structural schematic diagram of the utility model; Figure 2 This is a schematic diagram of the structure of the utility model after the connecting frame is rotated; Figure 3 It is a structural schematic diagram of a connecting frame and a connecting mechanism of the utility model.

[0019] A variable grip welding gun comprises a welding gun body 1, an extension tube 2 is connected to the welding gun body 1, an axle 3 is provided on the extension tube 2, the axle 3 passes through a waist-shaped hole 5 on a connecting frame 4, a connecting mechanism 6 for connecting the extension tube 2 is fixed inside the connecting frame 4, a base 7 is fixed on the connecting frame 4, and a handle 8 is detachably connected to the welding gun body 1.

[0020] The outer wall of the welding gun body 1 is provided with a thread, the inner wall of the extension tube 2 is provided with a thread, and the welding gun body 1 and the extension tube 2 are threadedly connected together.

[0021] As attached Figure 3 As shown, the connecting frame 4 is a U-shaped frame.

[0022] The connecting mechanism 6 is a magnet for magnetically attracting the extension tube 2 .

[0023] A friction layer is fixed to the bottom of the base 7 .

[0024] The friction layer is made of silicone or rubber.

[0025] A limit block 9 for limiting the rotation angle of the connecting frame 4 is fixed on the connecting frame 4 .

[0026] A screw is provided at the top of the handle 8 , and the screw is threadedly connected in a threaded hole on the welding gun body 1 .

[0027] As attached Figure 1As shown in the figure, when the welding gun is to be placed vertically, the connecting frame 4 is rotated downward until the limit block 9 is pressed against the welding gun body 1. At this time, the connecting frame 4 and the welding gun body 1 are in a vertical state. Then the base 7 is placed on a plane, and the welding gun can be placed in an upright state. Figure 2 As shown, when entering a narrow space for operation, the connecting frame 4 is swung back 90 degrees, and then the connecting frame 4 is horizontally moved toward the extension tube 2 until the connecting mechanism 6 (magnet) magnetically attracts the extension tube 2. When the length of the welding gun is to be adjusted, only the extension tube 2 needs to be rotated, and the extension tube 2 will move along the welding gun body 1.
