Preferably, in the aforementioned protective cover for a table saw, the bottom of the auxiliary protective cover of the motion protective cover and the bottom of the main body of the protective cover are located on the same horizontal line. The bottom of the auxiliary protective cover and the bottom of the protective cover body of the sports protective cover are always in close contact with the top of the wood. On the one hand, it can better block and absorb the sawdust and dust generated when the wood is cut. On the other hand, when the wood is about to be cut When the cutting is finished, the auxiliary protective cover can be dropped immediately when the sports protective cover has not fallen, so as to ensure that the sawdust and dust generated when cutting the wood will not be thrown out by the saw blade and will not fly to the operator, but by other Inhaled by the special dust suction device, which has a better dust removal effect.

Compared with the prior art, the utility model can achieve a good dust removal effect. The dust outlet pipe on the protective cover body in the utility model can be connected with a dust suction device, thereby collecting wood chips and dust in the protective cover body. The utility model The auxiliary protective cover on the middle movement protective cover can block the wood chips and dust thrown out by the saw blade at the moment when the wood is completely cut, so as to avoid the impact on the operator and the environment. It not only protects the saw blade, but also can To achieve a very good dust removal effect, the performance is more excellent.
