Detailed Description

Embodiments of the present invention will now be described with reference to the accompanying drawings.

Examples

The utility model discloses a concrete embodiment is as shown in fig. 1 to 5, a sand paper fixer of polishing, including handle 1, be connected with first arm 2 and second arm 3 on the handle 1, all be equipped with the sand paper fixed knot structure of interval arrangement on first arm 2 and the second arm 3 both. The first arm body 2 is fixedly connected with the handle 1, and one side of the first arm body 2 is connected with a guide rail 9. The second arm 3 is in sliding fit with the guide rail 9, and a return spring 14 is connected between the second arm 3 and the guide rail 9. The return spring 14 is in a compressed state, tending to urge both the first arm 2 and the second arm 3 into a principle with respect to each other. A locking structure is also arranged between the second arm body 3 and the guide rail 9. The handle 1, the first arm body 2 and the second arm body 3 are arranged in a Y shape.

The locking structure comprises a first locking bolt 10 which is in threaded connection with the second arm body 3, and the top end of a screw rod of the first locking bolt 10 is in contact with the guide rail 9.
