[0036] In the specific implementation of the present invention, when the shielding gas is ejected from the gas outlet 15 provided between the outer protruding ring 13 and the inner protruding ring 14, the fan blade 18 is pushed by the gas flow force, and then the sliding ring 17 starts to rotate, thereby pulling the shield 21 to rotate, which can block the welding spatter. Moreover, since the shield 21 is made of 83F alumina powder, it will not be melted with the welding spatter. Moreover, the shield 21 is provided with a strip-shaped vent 22, so that the shielding gas can be easily discharged. When the protective cover 21 needs to be replaced, since the protective cover 21 is integrally formed with the protective transition cylinder 20, and the protective transition cylinder 20 is provided with a ring array of locking holes 30 that cooperate with the ceramic column 27, the locking holes 30 are provided with an oblique chamfer 31 that cooperates with the arc transition surface 29 of the ceramic column 27, and the end of the connecting cylinder 19 is connected to the transition ring 23, and the end surface of the transition ring 23 is provided with an outer ring 24 and an inner ring 25, the outer ring 24 and the inner ring 25 are coaxially arranged and are integrally formed with the transition ring 23, and the outer ring 24 is The inner wall and the outer wall of the inner ring 25 are both provided with an annular array of blind holes 26, and a ceramic column 27 is matched in the blind hole 26.

Therefore, when the protective cover 21 is disassembled, only the protective cover 21 needs to be twisted to rotate the protective transition cylinder 20, and then the chamfer 31 on the locking hole 30 is aligned with the ceramic. The arc-shaped transition surface 29 at the end of the ceramic column 27 cooperates to cause the spring 28 to be compressed, and then the protective cover 21 can be pulled out. When the protective cover 21 is not twisted, the locking hole 30 and the end of the ceramic column 37 will be engaged, which is relatively firm. Moreover, since the welding wire is placed on the peripheral plate during operation and transportation, it is in a bent state when the welding wire is output. After passing through the transverse support arm 3 of the present invention, it will be straightened by the straightening rollers 5 symmetrically arranged up and down in the wire passing cavity 4 of the transverse support arm 3, which makes it more convenient to output the welding wire.
