[0025] The positioning mechanism assembly 2 is provided with a positioning support 21, one end of the positioning support 21 is sleeved with a rotating shaft 22, the rotating shaft 22 is respectively shafted through a rotating shaft spring 23 and a positioning spring plate 24, the bottom end of the positioning spring plate 24 presses the rotating shaft spring 23, the rotating shaft spring 23 is connected with a gasket 25, the gasket 25 is connected with a control hook 26, and the front end hook of the control hook 26 is clamped with the fixed tool holder 31.

[0026] Specifically, one end of the positioning support 21 is provided with a positioning column, a through hole is arranged in the column, the rotating shaft 22 is sleeved into the through hole, the one end of the rotating shaft spring 23 is wound on the rotating shaft 22, the one end of the positioning spring plate 24 is provided with a through hole on both sides, the through hole is penetrated by the rotating shaft 22, and the both ends of the rotating shaft spring 23 are connected with the through hole, the bottom surface of the positioning spring plate 24 presses the rotating shaft spring 23, the control hook 26 spans the bottom of the positioning support 21, the front end hook clamps the fixed tool holder 31, and the tail end of the control hook is provided with a spring hole 261, which is clamped by the rotating shaft spring 23. At this time, the tool head assembly 3 cannot be separated from the machine body even if it encounters a large resistance during the working process. When external force is applied to the tail end of the control hook to move the control hook 26 forward, the hook is separated from the fixed tool holder 31, and the tool head assembly 3 can be separated from the machine body. When the external force is removed, the control hook 26 is reset by the characteristics of the rotating shaft spring 23.

[0027] The positioning support 21 is fixed on the machine body 1 by a fastener, and the fixed tool holder 31 and the fixed tool holder 33 form a positioning groove 39, the positioning groove 39 is sleeved into the positioning spring plate 24, and the tool head assembly can be assembled into the machine body 1 by pressing.

[0028] Specifically, the positioning groove 39 is fitted into the positioning spring 24, and is pressed down, so that the cutter head assembly 3 is installed into the machine body 1. By exerting force on the control hook tail of the positioning mechanism assembly 2, the cutter head assembly 3 is pushed forward, and at this time, the cutter head assembly 3 is bent backward, so that the cutter head assembly 3 is separated from the machine body. Thus, the cutter head assembly can be quickly disassembled without the aid of additional tools.

[0029] In some embodiments, the fixed tool holder 31 is provided with a clamping hole 310 on each side, which cooperates with the clamping buckle 321 provided on the inner side of the guide rail 32. The guide rail 32 is provided with a guide rail groove 320 on each side, which is used to limit the movement track of the fixed tool holder 33. The fixed tool holder 33 is provided with an inward clamping strip 330 on each side, which is fitted into the guide rail groove 320.

[0030] Specifically, the clamping hole 310 is provided with a plurality of clamping buckles 321, so that the two are connected together. Because the fixed tool 34 is fixed on the end face of the fixed tool holder 33 by a fastener, and the clamping strip 330 is fitted into the guide rail groove 320, the clamping strip can slide along the guide rail groove 320 and can only slide along the guide rail groove 320, and cannot be separated. The movement of the fixed tool holder can bring the fixed tool to move.

[0031] In some embodiments, the fixed tool holder 31 is provided with a limiting groove 311, a limiting block 312 and a pressing block 313 at the front end. The spiral end of the spring 37 is arranged in the limiting groove 311, and the limiting block 312 limits the spring 37 from being separated from the fixed tool holder 31.
