[0001] This utility model relates to the field of sandpaper holder technology, specifically to an improved sandpaper holder that makes it easy to replace sandpaper. Background Technology

[0002] Sandpaper is a commonly used auxiliary tool that can make the surface of equipment smooth and flat. Sandpaper usually needs to be used with a sandpaper holder. The sandpaper holder is a tool used for sanding and polishing the surface of products. The sandpaper is attached to the bottom of the sandpaper holder for sanding.

[0003] The way sandpaper is glued to the sandpaper holder makes it difficult to remove the remaining sandpaper from the holder, making it inconvenient to replace with new sandpaper. This results in the sandpaper holder not being usable repeatedly, greatly reducing its applicability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an improved sandpaper holder that facilitates sandpaper replacement. This solves the problem that sandpaper is attached to the holder with adhesive, making it difficult to remove residual sandpaper and replace it with new sandpaper. This results in the sandpaper holder being unusable and significantly reducing its applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved sandpaper holder for easy sandpaper replacement includes a sanding plate with a handle on its top surface. Clamping grooves are formed on the top surfaces of the sanding plate on both sides of the handle. Clamping plates are provided within the clamping grooves to fix the ends of the sandpaper. One end of each clamping plate is rotatably connected to the inner wall of the clamping groove. Drive rods are symmetrically arranged on both sides of the other end of the clamping plate. Snap-fit ​​grooves are formed at both ends of the sanding plate for engaging the drive rods after the clamping plate rotates. Stops are symmetrically slidably arranged on the outer walls of the sanding plate on both sides of the snap-fit ​​grooves. A fixing plate is fixed to the outer wall of the sanding plate at the end of each stop away from the snap-fit ​​groove. A guide rod, one end of which is connected to the stop, is slidably connected to the fixing plate.

[0007] As a preferred technical solution of this utility model, the bottom end face of the clamping plate is provided with a plurality of uniformly distributed clamping blocks, and the clamping groove is provided with a clamping groove adapted to the clamping blocks.

[0008] The above technical solution improves the tightness of the sandpaper end by using the clamping block and clamping groove.

[0009] As a preferred embodiment of this utility model, the sandpaper has symmetrically arranged hook-and-adhesive surfaces at both ends on one side, and the clamping groove has an annular adhesive surface that cooperates with the hook-and-adhesive surfaces.

[0010] By using the above technical solution and the setting of the ring adhesive surface and the hook adhesive surface, it is easier for workers to initially fix the sandpaper on the sandpaper holder, thereby improving the installation efficiency of the sandpaper.

[0011] As a preferred technical solution of this utility model, a guide block is provided on the inner end face of the stop block, and a guide groove for displacement of the guide block is provided on the outer end face of the grinding plate.

[0012] By using the above technical solution and the design of the guide groove and guide block, the stability of the stop block displacement is improved.

[0013] As a preferred technical solution of this utility model, a drive spring is coaxially sleeved on the outer side of the guide rod, one end of the drive spring is fixedly connected to the stop block, and the other end of the drive spring is fixedly connected to the fixing plate.

[0014] The above technical solution utilizes the elastic force generated by the compression of the drive spring to drive the stop block to reset.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In use, this invention involves first laying the sandpaper flat with the hook-adhesive side facing upwards. The sanding plate is then placed centered on the sandpaper, and both ends of the sandpaper are bent and pressed into the clamping grooves of the sanding plate. This ensures the hook-adhesive side of the sandpaper adheres to the annular adhesive side within the clamping groove, initially fixing the sandpaper to the sandpaper holder. Next, the clamping plate is rotated to close, pressing and securing the sandpaper within the clamping groove. The drive rod on the clamping plate presses the two stops outwards, causing the drive rod to engage with the engaging groove, thus limiting and fixing the clamping plate, completing the sandpaper installation. This invention features a simple structure and convenient use, effectively securing and clamping the sandpaper, preventing it from falling off during sanding and affecting the sanding progress. It also facilitates sandpaper replacement by workers, improving its applicability. Attached Figure Description
