When the steel plate is placed on the shearing table 12, the power of the air pump 23 can be turned on. At this time, the air pump 23 will start to draw air outwards. The wind will pass through the air inlet 21, the filter 24, the air pipe 22 in sequence and then be discharged outwards through the air pump 23. At this time, the steel plate placed on the shearing table 12 will be sucked above the shearing table 12 to achieve the purpose of fixing the steel plate. At the same time, the filter 24 will automatically prevent impurities from entering the air pipe 22 and the air pump 23. The power of the linear motor 31 can be turned on as needed. At this time, the linear motor 31 will drive The first telescopic rod 32 fixed to the first telescopic rod 32 starts to move, and the first telescopic rod 32 will drive the fixed block 15 to start moving.

When the shearing work is completed, the dust hood 5 can be pulled to insert the dust hood 5 into the guide channel 2, and then the power of the air pump 23 can be turned on. At this time, Some impurities will enter the corrugated hose 51 and the waste box 52 in turn through the dust hood 5 to achieve the purpose of collecting impurities. The discharge box 6 can be inserted into the waste box 52. When the waste falls into the waste box 52 through the corrugated hose 51, the discharge box 6 will automatically collect the material. When the discharge box 6 is full, the handle 61 can be used to pull the discharge box 6 out of the waste box 52, and the waste can be poured out or recycled. The second rotating shaft 7 will automatically reduce the friction between the discharge box 6 and the waste box 52.
