The beneficial effect of above-mentioned structure does: this carbon dioxide gas protects welder has simple structure, the stable performance is reliable, the assembly, dismantle convenient advantage, be provided with the quick-operation joint that is connected with the return bend of rifle head in this handle, when the assembly, only need pass the mounting hole with the fixed part of return bend, insert the fixed part at the centre gripping inslot, screw the screw of upper cover again, can fix the fixed part of return bend in the centre gripping inslot, when changing the rifle head, need not unpack whole handle apart to be convenient for the assembly or the dismantlement of handle and rifle head.
Particularly, the locking plate be the L type, one of locking plate serve and be provided with the arc wall, the arc wall contradict in the draw-in groove of fixed part, and constitute the joint cooperation of locking plate and return bend. The arc-shaped groove can be clamped in the clamping groove of the fixing part, so that the connection between the bent pipe and the quick connector is more compact.
Particularly, a holding part is formed on one side of the shell corresponding to the button switch, an anti-slip rubber sleeve wraps the holding part, and an arc-shaped blocking part is formed on the shell corresponding to the position between the holding part and the button switch. The arc-shaped baffle part is arranged on the shell and is separated between the button piece and the holding part, the arc-shaped baffle part can prevent an operator from touching the button piece of the button switch by mistake to trigger the button switch, and the anti-skid rubber sleeve can improve the holding hand feeling of the handle.
