Further setting the following steps: the supporting component comprises a first supporting rod hinged to the moving part and a second supporting rod hinged to the first supporting rod.

Through adopting above-mentioned technical scheme, the cooperation between the second bracing piece and the first bracing piece is used for changing the distance between articulated position to the moving member between the two to realize shrink or expansion.

Further setting the following steps: the control assembly comprises a connecting ring which is arranged on the moving member in a sliding mode and moves towards the first supporting rod in a reciprocating mode and a ring sleeve which is in threaded connection with the moving member and is used for controlling the connecting ring to move, and the free end of the second supporting rod is hinged to the connecting ring.

Through adopting above-mentioned technical scheme, ring cover and moving member threaded connection are used for driving the go-between and move towards first bracing piece for change the angle that forms between first bracing piece and the second bracing piece between the two, thereby realize shrink or expansion regulation.

Further setting the following steps: the moving member includes a telescopic rod.

Through adopting above-mentioned technical scheme, think and control the removal of air feed box through the flexible of telescopic link.

Further setting the following steps: and the gas supply pipeline is provided with a flow regulating valve.

Through adopting above-mentioned technical scheme, flow control valve's setting is used for controlling the flow of gas supply line to reduce inert gas's waste.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses can reduce inert gas's use amount to reduce welding cost.
