A spring 1203 is fixedly connected to the top of the inner cavity of the mounting hole 1202. A clamping block 1204 is fixedly connected to the bottom of the spring 1203. A connecting rod 1205 is fixedly connected to the bottom of the clamping block 1204. A grinding disc 1207 is fixedly connected to the bottom of the connecting rod 1205. A waste collecting trough 13 is fixedly connected to the bottom of the workbench 1 to collect debris generated by grinding and prevent debris from accumulating on the mounting table 3 and affecting the grinding work. A bracket 14 is fixedly connected to the bottom edge of the workbench 1, and the bracket 14 provides good support for the entire device.

[0019] In this embodiment, during the grinding work, the dust collection component 8 can immediately suck away the debris generated by grinding and effectively prevent the debris from splashing to avoid polluting the working environment. At the same time, the debris that is not sucked away by the dust collection hood is cleaned into the waste collection tank 13, which is convenient for collecting the debris generated by grinding and preventing the debris from accumulating on the mounting table 3 and affecting the progress of the grinding work.

[0020] like Figure 8 As shown, a baffle 1206 is fixedly connected to the bottom of the inner side wall of the mounting hole 1202, and a connecting rod 1205 is slidably sleeved in the inner cavity of the baffle 1206.
