Be connected with first spring between the hinge point of described first rocking bar and first stator and the middle part of second rocking bar, be used to affect first rocking arm to keep inactive state.
Be connected with second spring between the middle part of described second stator and second rocking arm, be used to affect second rocking arm to keep inactive state.
Because first rocking arm, second rocking arm all are to flexibly connect, can freely swing, air-suction cover just can swing to the optional position, and the tractive force of first spring and second spring just can balance first rocking arm, the strength of second rocking arm tenesmus, make first rocking arm, second rocking arm keep static, it is constant that air-suction cover just can the holding position, and the handle of pulling gas skirt is moved gas skirt to suitable position when needing to change.
The utility model also provides a kind of weldering fume purifier that adopts the air-breathing arm of this universal flexibility, comprise the casing that has air inlet and gas outlet, be provided with gas-filtering device and blower fan in the casing, described air inlet place is connected with the air-breathing arm of described universal flexibility, wherein the air inlet centre is provided with bearing by support, the bolster of the air-breathing arm of universal flexibility inserts in this bearing, and the edge is sealed and matched with the air inlet edge at the bottom of the support tube of the air-breathing arm of universal flexibility.
Described gas-filtering device comprises that the cross section in columnar filter screen and the filter screen is leg-of-mutton bracing frame.
Described bracing frame is hollow closed shell, and profile is a triangular prism, and columnar filter screen set is in its outside, and three lateral support of triangular prism are at the inwall of filter screen.
Described bracing frame is communicated with the inlet of blower fan by the air channel with space between the circle tube leaching net.
Described air inlet is positioned at the casing top, and described gas outlet is positioned at the bottom of casing.The base plate of described casing is netted and as the gas outlet of casing.
In order to reduce noise, post puigging at the inwall of casing, puigging adopts the good materials of sound-absorbing effect such as sponge.
The air-breathing arm air-suction cover of the universal flexibility of the utility model can swing to the optional position, the holding position is constant then, adopt in the weldering fume purifier of the air-breathing arm of this universal flexibility, adopt triangular prism shaped screen support frame, itself and circle tube leaching net sticking part plane amass very little, only be three sides of triangular prism, guaranteed ventilation and filter effect.
