Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-5, an electric grinder, including electric grinder body 1, the outside sliding connection of electric grinder body 1 supports cover 2, the lateral wall that supports cover 2 has fixed pin 3 through threaded connection, fixed pin 3 and the contact of electric grinder body 1, through setting up fixed pin 3, fix supporting cover 2, it has guide arm 4 to slide in the chimb that supports cover 2 to cup joint, the welding has dog 5 on the guide arm 4, dog 5 and the chimb contact that supports cover 2, through setting up dog 5, it is spacing to guide arm 4, it has translucent cover 6 to bond on the guide arm 4.

In this embodiment, opening 61 has been seted up on translucent cover 6, sliding connection has electric grinder body 1 in opening 61, through setting up opening 61, make translucent cover 6 can slide on electric grinder body 1, the outside of guide arm 4 is provided with pressure spring 7, the one end of pressure spring 7 and the chimb contact of supporting cover 2, the other end and the translucent cover 6 contact of pressure spring 7, through setting up pressure spring 7, make translucent cover 6 can be elastic sliding on electric grinder body 1, install bistrique 9 on electric grinder body 1's the output shaft 8, it has ripple cover 10 to bond on translucent cover 6, ripple cover 10 and output shaft 8 rotate to be connected, annular 12 has been seted up on the output shaft 8, be provided with bulge loop 11 in the ripple cover 10, bulge loop 11 and annular 12 sliding connection.
