Description

Technical Field

[0001] This utility model relates to the field of sandpaper holder technology, specifically a sandpaper holder that provides stable clamping. Background Technology

[0002] Depending on the abrasive material, there are various types of sandpaper, including diamond sandpaper, synthetic diamond sandpaper, and glass sandpaper. Dry sandpaper (wood sandpaper) is used to polish the surfaces of wood and bamboo, while water-resistant sandpaper (wet sandpaper) is used to polish the surfaces of metal or non-metal workpieces in water or oil.

[0003] When using existing sandpaper holders, the sandpaper is wrapped around the base plate of the holder and clamped by clips on both sides of the base plate. Since the clamping force of the sandpaper holder is provided by springs, the clamping force is limited. During the sanding process, the sandpaper is subjected to greater friction, which can easily cause the sandpaper to come out of the clips, resulting in paper detachment and affecting the sanding progress. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a sandpaper holder that provides a stable clamping mechanism. This solves the problem that during sanding, the sandpaper experiences significant friction, making it prone to slipping out of the clamp and affecting the sanding progress.

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

[0006] A sandpaper holder with a secure clamping mechanism includes a base plate. Connecting plates are symmetrically arranged on the left and right sides of the base plate. A first through-slot extending along the length of the connecting plate is formed on the outer wall of the connecting plate. An assembly plate is detachably provided on the connecting plate. A mating plate perpendicular to the top of the assembly plate is provided, and a first clamping plate parallel to the mating plate and capable of being inserted into the first through-slot is provided at the bottom of the assembly plate. Second through-slots are symmetrically formed at both ends of the top surface of the base plate. Multiple guide posts are fixedly connected to the top surface of the base plate inside the second through-slots. Fastening plates are detachably provided at both ends of the base plate. The bottom surface of the fastening plates has guide grooves for inserting the guide posts and a second clamping plate capable of being inserted into the second through-slots.

[0007] As a preferred technical solution of this utility model, the two ends of the docking plate are symmetrically provided with third fixing holes for fixing bolts to be inserted, and multiple positioning strips are evenly distributed on the bottom end face of the docking plate between the two third fixing holes. The connecting plate is provided with first fixing holes that are connected to the third fixing holes one by one, and the top end face of the connecting plate is provided with positioning grooves for positioning strips to be inserted.

[0008] As a preferred technical solution of this utility model, pressure plates are symmetrically provided on both sides of the top of the fastening plate, and a second fixing hole is provided through the pressure plate and is connected to the third fixing hole.

[0009] As a preferred embodiment of this utility model, the top end face of the base plate is provided with a handle.

[0010] As a preferred embodiment of this utility model, the top of the fixing bolt is provided with a drive handle.

[0011] As a preferred embodiment of this utility model, the connecting plate and the base plate are integrally formed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Compared to existing technologies where sandpaper holders only clamp the sandpaper on both sides, this invention can press and fix the sandpaper around all four sides, increasing the pressing area and keeping the sandpaper taut. This ensures the flatness of the sandpaper, prevents it from shifting or coming off, guarantees its stability during sanding, extends its lifespan, and improves its efficiency, thus ensuring the sanding progress.
