2. The device during operation, hollow return bend can periodically breathe in and jet-propelled work, if weld at jet-propelled in-process, hollow return bend blows away toxic gas, makes the purifying effect variation of device, because the whistle goes on with the work of bleeding in step, so welding personnel carry out spot welding work to the panel beating when hearing the whistle, can make hollow return bend furthest absorb the toxic gas that the welding produced, avoid appearing cooling work and the problem of purification work mutual interference.
3. The device's clamping plate can press from both sides the panel beating edge that inserts the inner wall tightly, prevents that the panel beating from sliding at will at the welded in-process, because the panel beating is usually thinner, so the clamping plate can press from both sides the edge of panel beating excessively, leads to the surface of panel beating to appear pressing from both sides the trace, and the pressure cell board can receive the effect with the effect that the panel beating appears through vertical push rod, makes the clamp force that operating personnel can monitor the pressure cell board constantly and receive, avoids pressing from both sides excessively to the panel beating.
4. When carrying out weldment work, the part toxic gas that the welding produced can pass through the inside that hollow return bend absorbed the device, and then reduce environmental pollution, because hollow return bend can only periodically extract waste gas, so when hollow return bend carries out cooling operation, the adherence baffle is hugged closely with the inner wall of the shell that admits air, the shell that admits air is in relative seal state, under the circumstances of guaranteeing the continuous operation of aspiration pump, make the shell that admits air possess the function of periodically bleeding, the inside pressure reduction of the shell that admits air simultaneously, also be favorable to bleeding the during operation next time, can take out the inside gas of bar bellows fast, the rotation efficiency of synchronous fixed commentaries on classics board, the extraction work of the shell that admits air has been accelerated.
5. Because the in-process at hollow return bend extraction waste gas, inevitably can also extract the inside of bar bellows with the residue, then input protecting sheathing's inside through connecting the siphunculus, and the purifying box can only purify waste gas, excessive residue gets into the purifying box and probably makes the purifying box jam, and filter slide can avoid self hole to be plugged up by the residue through the mode of shaking off, protecting sheathing is inside also can reduce the volume that gets into the purifying box residue through the resilient hole board, and inclined plane guide board upper portion is difficult to pile up the residue, make the device can carry out continuous operation for a long time.
