[0003] The harmful gas collection workbench in the prior art is usually composed of a table with holes and a dust hood, which is connected to an external negative pressure pipe. The fine dust on the table is drawn out from the holes through the negative pressure and falls into the dust hood, and then sucked from the dust hood into the negative pressure pipe and discharged. However, in order to ensure sufficient suction force, most of the harmful gas collection workbenches on the market pre-connect the dust hood with the workbench and take sealing measures at the connection before leaving the factory. However, such workbenches are large in size and inconvenient to transport after sale. The assembled harmful gas collection workbench has poor sealing performance, and the suction force of the negative pressure pipe is easily wasted. In addition, the coverage area of ​​the dust hood is much larger than the area of ​​the negative pressure pipe. When inhaling, the dust on the workbench near the center of the negative pressure pipe is subject to greater suction and is easily sucked out, while the dust far away from the negative pressure pipe is not easily sucked out, which results in uneven dust removal effect on the workbench.
