DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0023] like Figures 1 to 4As shown, a chamfering tool with a fastening mechanism comprises a tool handle clamping block 1, a tool handle connecting block 2 is fixedly connected to the rear of the tool handle clamping block 1, a blade mounting block 3 is movably connected to the rear of the tool handle connecting block 2, a blade mounting groove 4 is provided on the rear end outer wall of the blade mounting block 3, a blade 5 is movably mounted on the outer wall of the blade mounting groove 4, a blade fixing hole 14 is provided on the outer wall of the blade mounting groove 4, a blade limiting hole 15 is provided on the outer wall surface of the blade 5, a blade fixing screw 8 is installed on the internal thread of the blade limiting hole 15, and the blade 5 can be replaced by screwing out the blade fixing screw 8 from the inside of the blade limiting hole 15 and the blade fixing hole 14. The blade 5 is replaced by the bevel blade 7, which can avoid the difference in precision caused by damaging the right-angled edge 6 and the bevel blade 7 when cutting the workpiece. The bevel blade 7 is fixed on the lower side of the blade 5, and the right-angled edge 6 is fixedly connected to the upper side of the bevel blade 7, which can avoid the user from replacing the blade mounting block 3 as a whole. While ensuring the quality of the cutting workpiece, it also saves the tool cost. After a single blade 5 is worn, it can be replaced individually, reducing the economic loss of the user. The blade 5 installed in the blade mounting groove 4 behind the blade mounting block 3 can be quickly replaced, and the right-angled edge 6 and the bevel blade 7 arranged on the outer side of the blade 5 can achieve the purpose of one knife for multiple uses, thereby improving the convenience of the device when used. Embodiment 2

[0024] In addition to all the technical features of the first embodiment, the present embodiment also includes: a limit block installation groove 11 is provided at the connection end between the handle connecting block 2 and the blade mounting block 3, a fixed block installation groove 16 is provided at the front end of the limit block installation groove 11, a fixed block installation groove 12 is provided at the rear end of the limit block installation groove 11, the fixed block installation groove 16 is located on the outer wall of the handle connecting block 2, the fixed block installation groove 12 is located on the outer wall of the blade mounting block 3, a mounting seat 18 is provided below the fixed block installation groove 16, a mounting seat 17 is provided below the fixed block installation groove 12, and the outer wall surfaces of the mounting seat 17 and the mounting seat 18 are provided with fixed The limiting block 9 is movably installed on the outer wall of the fixed hole 19, the limiting block mounting groove 11, the fixed block mounting groove 12 and the fixed block mounting groove 2 16, and the outer periphery of the limiting block 9 is fixedly connected to the limiting block 20. The upper outer wall of the limiting block 20 is provided with a fixed mounting hole 13, and the internal thread of the fixed mounting hole 13 is installed with a limiting fixing screw 10. By unscrewing the limiting fixing screw 10 from the inside of the fixed mounting hole 13 and the fixing hole 19, the limiting block 9 is removed from the inside of the limiting block mounting groove 11, the fixed block mounting groove 12 and the fixed block mounting groove 2 16, which can facilitate the user to replace the handle connecting block 2 and the blade mounting block 3.
