[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4In this embodiment of the present invention, an anti-detachment grinding tool fixing device includes a grinding tool body 1 and two insert tubes 15. The two insert tubes 15 are fixedly installed on the back of the grinding tool body 1, and each insert tube 15 has an insert plate 12 inserted into it. The top of the two insert plates 12 is fixedly connected to the same mounting plate 2. The back of the two insert plates 12 is tightly fitted with the same limiting plate 4. Two second screw holes 11 are symmetrically opened on one side of the two limiting plates 4. A first screw hole 10 is opened on one side of each of the two insert plates 12, and the same fixing screw 5 is threaded through the first screw hole 10 and the second screw hole 11 on each side.
