[0027] In order to solve the problem of insufficient safety of the traditional sandpaper cutting tool in use, the utility model embodiment provides a sandpaper cutting tool. The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] Please refer to Figures 1-5 The utility model provides a sandpaper cutting tool, including bearing frame 1, the lower part of bearing frame 1 is connected with sandpaper cutting knife 3 through bolt 2, bearing frame 1 is located sandpaper cutting knife 3 both sides and is provided with safety protection assembly 4, safety protection assembly 4 includes the protection plate 401 located bearing frame 1 lower part both sides, the protection plate 401 is located sandpaper cutting knife 3 side wall and is provided with two connecting plates 402, the upper portion of connecting plate 402 is provided with guide rod 403, and the guide rod 403 is slidably connected between bearing frame 1, wherein the protection plate 401 is linearly moved on the both sides of bearing frame 1 through guide rod 403. The outer circumferential side of guide rod 403 is provided with return spring 404, and the return spring 404 is located between bearing frame 1 and connecting plate 402, so that connecting plate 402 is connected to protection plate 401 and elastically moves on the side of bearing frame 1 through return spring 404. The four around bearing frame 1 is provided with channel 101 for the insertion of guide rod 403, and the inner diameter of channel 101 is greater than the outer diameter of guide rod 403.
