Claims

[Scope of utility model registration request]

The workpiece W side has a space 1a opened on the inside, a hose 2 for supplying inert gas is directly connected to this space 1a, and a sliding plate having insulation properties on the surface facing the workpiece W side. A welding part cover 1 to which a moving plate 1b is fixed, and a space 1a of the welding part cover 1 is held through an insulating material 4, and the surface on the side of the workpiece W is covered with an insulating plate 3a. An electrode holding member 3 to which welding current is supplied, and an electrode mounting tool 5 attached to the sliding portion 3c extending vertically through the electrode holding member 3 in such a manner that it does not come off on the side opposite to the workpiece W side. and,
An electrode 6 made of tungsten whose tip protrudes from a hole 3b provided in the insulating plate 3a and is fixed to the electrode fitting 5; and an electrode 6 which is fitted between the insulating plate 3a and the electrode fitting 5. An electrode mounting spring 7 that presses the mounting tool 5 to the side opposite to the workpiece W side, and a cylindrical push button that is fixed through the welding part cover 1 at a position opposite to the workpiece W side. A sliding member 8, a columnar space 9a that is slidably attached to the push button sliding member 8 in a structure that does not come off on the side opposite to the welded object W side, and is open on the welded object W side, and this columnar space 9a. A push button 9 has long grooves 9b located on both sides of a columnar space 9a, and a shaft hole 8a extending vertically through the push button sliding member 8 toward the workpiece W side protrudes toward the workpiece W side. An insulating piece 11 having a diameter larger than that of the shaft hole 8a is fixed to the end thereof, and a claw receiver part 10a is fixed to the other end located in the columnar space 9a of the push button 9. A shaft 10, a pushbutton spring 12 that is attached between the pushbutton sliding member 8 and the pushbutton 9 and presses the pushbutton 9 toward the side opposite to the workpiece W, and the pushbutton sliding member 8. and a shaft spring 13 which is wound around the shaft 10 between the claw receiver of the shaft 10 and the lower surface of the portion 10a and presses the shaft 10 toward the side opposite to the workpiece W side;
Shaft 10 is placed on the shaft 10 side opposite to the workpiece W side.
The pawl 14b that engages with the portion 10a is also connected to the shaft 1.
A diagonally cut inclined surface 14c is provided on the workpiece W side opposite to the 0 side, and is rotatably mounted on a shaft 14a provided in the center of the long groove 9b of the push button 9. The ratchet 14 is connected to the ratchet 14, and the hook is rotated on the side opposite to the workpiece W side from the shaft 14a of the ratchet 14.
The TIG is characterized by comprising an elastic ring 15 pressing each of the four claws 14b toward the shaft 10 side.
