[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This is a welding fume absorption hood, which is provided with a suction assembly, which includes a suction hood and a locking device. A slot for connecting a welding gun is opened on the side of the suction hood, and a suction pipe is connected to one end of the suction hood; the locking device is installed on the suction hood, and the locking device is correspondingly installed above the slot. Compared with the suction device provided on one side of the welding gun, this device better absorbs welding fume and welding dust in all directions, avoiding affecting environmental quality and human health.

[0012] 2. This type of fume absorption hood is used for welding. It is equipped with a locking device, which includes a fixing part and a bolt. The tightness of the welding gun can be adjusted by turning the bolt according to the size of the welding gun. It is suitable for a variety of welding guns. BRIEF DESCRIPTION OF THE DRAWINGS
