[0022] See also Figure 1 to Figure 4 In the embodiment of the utility model, a metal cutting tool that is easy to disassemble includes a tool accommodating base 1, a transverse plate 8 is fixedly provided in the inner cavity of the tool accommodating base 1, a fastening component is provided above the transverse plate 8 to perform secondary fastening on the cutting tool to ensure the stability of the metal cutting tool during operation, and an automatic locking mechanism is installed below the transverse plate 8 to realize flexible installation and disassembly of the cutting tool to meet the cutting requirements of different types of tools;

[0023] When in use, the automatic locking mechanism includes a spring 10 and a locking block 12, one end of the locking block 12 is fixedly connected to a connecting column 9, the other end of the connecting column 9 passes through the side wall of the tool accommodating base 1 and is limited to the outside, and a spring 10 is sleeved on the outside of the connecting column 9, and the connecting column 9 and the spring 10 are both slidably installed in the inner cavity of the supporting wall 11, one end of the supporting wall 11 passes through the side wall of the tool accommodating base 1, and the other end passes through the supporting plate 19, and the top of the supporting plate 19 is welded to the bottom end of the cross plate 8; when the locking block 12 contacts with the tool connecting piece 15, the spring 10 sleeved on the surface of the connecting column 9 begins to shrink due to the extrusion force, and loses the pressure of the extrusion force when the locking block 12 is clamped in the appropriate position, thereby restoring the original elasticity of the spring 10, so that the locking block 12 receives the opposite extrusion force, thereby achieving the purpose of automatic locking.

[0024] In one embodiment, specifically, the fastening assembly includes a movable plate 7 and a fastening plate 14, the fastening plate 14 is fixed to one end of the movable plate 7, the other end of the movable plate 7 is penetrated and sleeved on the middle surface of the cylindrical clamp 6, and the cylindrical clamp 6 is movably installed between the first H-type buckle plate 2 and the second H-type buckle plate 3. Under the driving action of the movable plate 7, the fastening plate 14 can be flexibly moved to adapt to the form characteristics of tools with different structures and meet the extrusion and tightening requirements of different types of tools.

[0025] Specifically, the first H-shaped buckle plate 2 and the second H-shaped buckle plate 3 have the same structure.
