When the gas containing debris and flying dust passes through the dust box, the gas will successively pass through the chip bin, the dust bin and the filter bin. When the gas passes through the chip collecting bin, the debris it contains will be intercepted by the interception net, so that the debris remains in the chip collecting bin. When the gas passes through the dust collecting bin, the dust in it will be intercepted by the dust-proof filter cloth and fall into the fixing liquid to prevent it from being raised again. Finally, the gas will be further purified by the air filter element in the filter bin to filter out the dust. Through the above process, the device can capture the debris and flying dust generated by grinding, which not only makes it convenient for users to clean the device, but also prevents people from inhaling too much flying dust and affecting their respiratory health.

Conversely, when the blade width is narrower, the user can adjust the distance between the guide rail slider and the grinding wheel so that the blade edge can contact the optimal grinding position. When the user needs to adjust the angle of the blade, the user can loosen the elastic twist block after clamping the blade with the clamping mechanism. At this time, the rotating joint part can be rotated and adjusted to change the angle of the blade. After adjusting to a suitable angle, the user can tighten the elastic twist block to fix the rotating joint part, thereby adjusting the grinding angle. Through the above process, the device can adjust the grinding angle according to the needs of use, and can also adjust the grinding distance according to the width of the blade, which is conducive to improving the applicability of the device.
