The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of welding helmet convenient to use, including One cap body, a mask, it is characterised in that: the mask is connected with each other by a shaft and the cap body；In the middle part of the mask, if A form is set, slot is respectively set in the left side, right side, downside of the form, a shading mirror can from top to bottom be inserted into described insert It can move up and down in slot and freely；The shading mirror top edge connects a drawstring, on the mask, the top of the shading mirror And upper left side, a runner is respectively set；A screw rod is arranged in the mask bottom righthand side, installs a nut, the spiral shell on the screw rod One lantern ring is set on mother, a lever is plugged in the lantern ring；The lever can be movable in the lantern ring, and can be with the spiral shell Mother moves up and down along the screw rod；The left end of the lever is connect with the drawstring.

Preferably, one first hook of mask right lower quadrant setting；First hook can be hooked on the lever Right end.

Preferably, at the form, a transmissive mirror is respectively set in the inner surface of the shading mirror, outer surface.

Preferably, a hanging nose is arranged in the shading mirror top edge, and the drawstring is connected on the hanging nose.

Preferably, one second hook of setting at the top of the cap body.

Preferably, a pallet is arranged in the lever middle, and the pallet can move left and right on the lever.

Preferably, a spring is set between the runner and the hanging nose of the top of the shading mirror.

Preferably, first hook is spring carrier arm.

Compared with prior art, the utility model has the beneficial effects that the shading mirror of the utility model is inserted into slot , if damage, can replace easily；Due to the presence of lever, electric welder needs to examine welding quality during the work time When, as long as opening mouth, so that it may easily pull on shading mirror and be observed with eyes, both hands can flexibly do more critical Thing, this has been considerably improved working efficiency；According to the opening degree of the chin of individual, by the way that nut is moved above and below along screw rod It moves to reconcile more to be appropriate to electric welder user；It, can be by one end of lever if not welding or observing quality etc. for a long time It hangs on the first hook, shading mirror can be lifted for a long time to work.Moreover, if the shading mirror damage on mask needs more When changing, pulled out out of slot on mask it is i.e. replaceable, so replacement it is very simple.
