[0026] The pushing spring 7 is sleeved outside the extension shaft 6. A grinding cone 8 is threadedly connected to the outer surface of the extension shaft 6. One end of the pushing spring 7 is a spring and the other end is a ring. The spring of the pushing spring 7 is fixedly connected to both ends of the extension shaft 6.

The pushing spring 7 can push the grinding cone 8 so that the grinding cone 8 always contacts the threaded rod 601 at both ends of the extension shaft 6, facilitating timely response when the extension shaft 6 rotates in reverse.
[0027] The grinding cone 8 is slidably connected to the inner wall of the grinding cylinder 4. The grinding cone 8 is in the shape of a frustum-shaped hollow shell and is provided with a sand layer for grinding on its surface. An outer snap ring 801 is provided on the outer surface of the grinding cone 8 and is snap-fitted to the inside of the grinding cylinder 4.

[0030] Working principle: When in use, first adjust the length of the device according to the usage space. By starting the extension motor 5 to drive the extension shaft 6 to rotate, the threaded rod 601 rotates and meshes with the end face disc 802, pushing the grinding cone 8 out from the inside of the grinding cylinder 4. At this time, the two sections of the grinding cylinder 4 and the grinding cone 8 can be used for grinding. When the grinding cone 8 slides to the end point in the grinding cylinder 4, the end face disc 802 cooperates with the round shaft 602. At this time, the grinding cone 8 drives the trigger cylinder 9 to make the toothed ring inside the matching cylinder 902 mesh with the gear 603. The extension shaft 6 continues to rotate, causing the gear 603 to push the trigger cylinder 9 to rotate, and the trigger cylinder 9 rotates to drive the engaged propulsion cylinder 10 to push it out, so that the grinding sharp corner 11 extends out from the inside of the grinding cone 8. At this time, the grinding cylinder 4, the grinding cone 8, and the grinding sharp corner 11 can be used for rotary grinding. Reverse the extension motor 5 to drive the extension shaft 6 to reverse. Driven by the pushing spring 7, the end face disc 802 contacts and meshes with the threaded rod 601, so that the grinding cone 8 is driven back into the inside of the grinding cylinder 4. At the same time, when the grinding cone 8 retracts, it drives the trigger cylinder 9 to disengage from the gear 603. At this time, the grinding cylinder 4 and the grinding sharp corner 11 can be used for grinding and rust removal. By continuing to reverse the extension shaft 6, the end face disc 802 cooperates with the round shaft 602 at the retraction end to achieve idling. At this time, the toothed ring inside the matching cylinder 902 meshes with the gear 603 at the retraction end, and the trigger cylinder 9 is driven to rotate, and the propulsion cylinder 10 drives the grinding sharp corner 11 to retract into the inside of the grinding cone 8. At this time, the grinding cylinder 4 is used for grinding and rust removal. The grinding motor 3 can drive the grinding cylinder 4 to rotate.
