The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the annular dust cap of the present invention;

in the figure, 1, a self-dust-absorption sander body, 2, a handle, 3, a ball, 4, a dust-prevention shielding mechanism, 5, an elastic part, 6, a connecting ring, 7, an annular dust-prevention cover, 8, an extension handle, 41, an annular part and 42, a fur body are arranged.

Detailed Description

Fig. 1 is a schematic structural view of the present invention, and fig. 2 is a schematic structural view of an annular dust cover of the present invention.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a prevent formula that dust leaks from dust absorption sanding machine, includes from dust absorption sanding machine organism 1 and handle 2, is in the same place from dust absorption sanding machine organism 1 and handle 2 are fixed, establish and the sliding fit is connected with annular dust cover 7 from dust absorption sanding machine organism 1 upper cover, and ball 3 is installed to annular dust cover 7 bottom border department, installs dustproof shielding mechanism 4 on the annular dust cover 7, is connected with elastic component 5 between annular dust cover 7 and the self dust absorption sanding machine organism 1.

The bottom edge of the annular dust cover 7 is provided with an annular groove, and a plurality of balls 3 are sequentially arranged in the annular groove.

The self-dust-collection sander body 1 is provided with a sliding rail, the inner side of the annular dust cover 7 is provided with a sliding groove, and the sliding groove of the annular dust cover 7 is matched with the sliding rail on the self-dust-collection sander body 1.

The elastic member 5 is a spring.

The self-dust-collection sander body 1 is sleeved with and fixed with a connecting ring 6, and a plurality of elastic pieces 5 are connected between the connecting ring 6 and an annular dust cover 7.
