Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] see figure 1 , 2 , the sandpaper clamping device includes a cylindrical clamping handle 1, and a semicircular installation gap 2 is provided on one end surface of the clamping handle. The installation gap is composed of an axial surface 3 along the axial direction of the clamping handle and a The radial surface 4 is formed, and the axial surface is provided with a compression block 5, and a locking bolt 6 passing through the compression block to lock the compression block on the axial surface. In a specific implementation, the length of the pressing block is less than or equal to the diameter of the clamping handle. There are two locking bolts. Several arc-shaped protrusions 7 are arranged on the end face of the pressing block opposite to the axial face.

Abstract

The invention relates to the technical field of abrasive paper and particularly relates to an abrasive paper clamping device. The device comprises a cylindrical clamping handle, and a semi-circular mounting notch is formed in one end face of the clamping handle and is formed by an axial face along the clamping handle axial direction and a radial face along the diameter direction. A compression block and locking bolts which penetrate the compression block to lock the compression block on the axial face are arranged on the axial face. The abrasive paper is arranged between the axial face and the compression block, the compression block is compressed towards the abrasive paper direction through the locking bolts, and the abrasive paper is compressed on the axial face by the compression block firmly, the abrasive paper cannot be thrown away even during high-speed rotation, smoothly sanding of work-pieces is guaranteed, and the sanding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sandpaper, in particular to a sandpaper clamping device. Background technique [0002] The existing sandpaper clamping device is to open a notch on one end of the round rod, place the sandpaper in the notch, and then clamp the round rod to the electric tool. The size of the notch is set according to the sandpaper of different thickness. Rotating, so that the sandpaper is easy to throw out, affecting the sanding work. Contents of the invention [0003] In view of the above technical problems, the present invention provides a sandpaper clamping device with a simple structure and capable of firmly clamping the sandpaper. [0004] Realize the technical scheme of the present invention as follows: [0005] The sandpaper clamping device includes a cylindrical clamping handle, and a semicircular installation notch is opened on one end surface of the clamping handle. The installation notch is composed of an ax...
