[0002] The sponge sanding disc is a kind of grinding and polishing material with sponge as the base and abrasive sand planted on the sponge. It is suitable for grinding and polishing the rough surface of materials such as solid wood furniture, metal stainless steel, automobile maintenance, machinery manufacturing, plastic glass, decorative crafts, etc.

[0003] Under the existing technology, in the process of sponge sanding disc production, workers usually use a grinder. The grinding disc of the grinder can grind the sponge sanding disc to improve the quality of the sponge sanding disc. The grinder is provided with a control lever. If the staff wants to control the operation of the grinding disc of the grinder, they need to hold the control lever with their hands all the time. Once the control lever is released, the grinding disc stops running. However, holding the lever with hands for a long time will bring burden to the staff and cause hand fatigue.

[0011] As an optimal solution of the grinding device for sponge sand disc production described in the utility model, a sliding rod is arranged in the built-in groove, both ends of the sliding rod are fixedly connected to the wall of the built-in groove, the interior of the guide block is slidably connected to the surface of the sliding rod, and the surface of the guide block is slidably connected to the wall of the built-in groove.

[0012] As an optimal solution of the grinding device for sponge sand disc production described in the utility model, one side of the moving block is fixedly connected to a trigger block, a limiting groove is provided on the top of the trigger block, a compression spring is arranged in the limiting groove, one end of the compression spring is fixedly connected to the bottom of the limiting groove, and the other end of the compression spring is fixedly connected to a positioning block.

[0013] As a preferred solution of the grinding device for producing sponge sand discs described in the utility model, an extension strip is fixedly connected to the bottom of the handle, and a first positioning groove and a second positioning groove are formed at the bottom of the extension strip.

[0014] As a preferred solution of the grinding device for sponge sand disc production described in the utility model, the first positioning groove and the second positioning groove are both arc-shaped groove structures, the positioning block is an arc-shaped block structure, the first positioning groove matches the positioning block, and the second positioning groove matches the positioning block.

[0015] Beneficial effects of the utility model:

[0016] When the tool is in use, the staff can grasp the handle and pinch the control rod with their hands, and the control rod moves in the direction close to the handle, and the grinding disc starts to operate. The staff pushes the trigger block to make the moving block move, and the moving block moves and drives the guide block to move synchronously along the sliding rod. The positioning block is retracted into the limiting groove under the extrusion of the extension bar, and the compression spring contracts and the elastic force increases. When the positioning block is aligned with the first positioning groove, the elastic force of the compression spring drives the positioning block to enter the first positioning groove, and the positioning block and the first positioning groove cooperate with each other to fix the position of the moving block and the docking block, and at this time the docking block enters the docking groove, and the docking block and the docking groove cooperate with each other to fix the position of the control rod. The design solves the shortcomings of the prior art. In the process of using the grinding disc to grind the sponge sand disc, the staff does not need to continue to pinch the control rod with his hands. When the staff releases the control rod, the grinding disc still keeps operating due to the locking effect of the docking block and the docking groove, which reduces the operating burden of the staff and relieves the fatigue of the hands.
