The tool body 1 is provided with a second sliding groove 9, and the outer surface of the first sliding block 6 is slidably connected with the second sliding groove 9.

[0027] The inner surface of the knife body 1 is fixedly connected to two limit blocks 11, and the inner surfaces of the two limit blocks 11 are slidably connected to connecting rods 12, one end of the two connecting rods 12 is fixedly connected to a fixed block 13, and the other end of the two connecting rods 12 is fixedly connected to a second slider 14, and the side surfaces of the two second sliders 14 are fixedly connected to a T-block 15, and the outer surfaces of the two fixed blocks 13 are movably connected to the two first sliders 6 respectively. A connecting groove 17 is provided on the knife body 1, and a positioning block 18 is fixedly connected to the inner surface of the connecting groove 17. The insert block 4 contacts the positioning block 18, and a positioning groove 10 is provided on the knife body 1. The groove 10 is connected with the connecting groove 17, the insert block 4 is adapted to the positioning groove 10, the outer surface of the connecting rod 12 is slidably sleeved with a spring 16, one end of the spring 16 is fixedly connected to the side surface of the fixed block 13, and the other end of the spring 16 is fixedly connected to the side surface of the limit block 11, an anti-slip groove 19 is provided on the knife body 1, the outer surface of the limit block 11 is fixedly connected to the anti-slip groove 19, the outer surfaces of the second slider 14 and the T-block 15 are both slidably connected to the anti-slip groove 19, the fixed block 13 corresponds to the anti-slip groove 19, and a fixed groove 20 is provided on the first slider 6, and the outer surface of the fixed block 13 is movably connected to the fixed groove 20.

[0028] Working principle: When the tool 2 needs to be replaced, first pull the T-block 15, so that the moving T-block 15 drives the second slider 14, the fixed block 13 and the connecting rod 12 to move, and at the same time the moving fixed block 13 squeezes the spring 16 on the limit block 11, so that the positioning block 18 is in a taut state. When the moving fixed block 13 is separated from the fixing groove 20 on the first slider 6 and enters the anti-slip groove 19, the restriction on the first slider 6 is released, and then the first slider 6 is pulled upward to make the second slider 14, the second slider 14 and the second slider 14 move upward. A slider 6 moves in the second slide groove 9 and drives the L-shaped block 5 to move in the first slide groove 8. When the moving L-shaped block 5 is separated from the limiting groove 7 on the insert block 4, the connection between the cutter body 1 and the cutter 2 is released, and then the cutter 2 is rotated, so that the rotating cutter 2 drives the connecting block 3 to rotate, so that the rotating connecting block 3 can drive the insert block 4 to move in the connecting groove 17. When the moving insert block 4 corresponds to the positioning groove 10, the cutter 2 is pulled outward, so that the moving cutter 2 drives the insert block 4 to pass through the positioning groove 10. The tool 2 is disengaged from the tool body 1 through the positioning groove 10, thereby realizing the disassembly of the tool 2, and then the insert block 4 on the new tool 2 is inserted into the tool body 1. When the insert block 4 is inserted into the connecting groove 17 through the positioning groove 10, the tool 2 is rotated in the opposite direction, so that the rotating tool 2 drives the connecting block 3 to rotate, and the rotating connecting block 3 drives the insert block 4 to move in the connecting groove 17. When the moving insert block 4 contacts the positioning block 18, the limiting groove 7 on the insert block 4 can correspond to the L-shaped block 5, and then the first slide block 6 is pushed downward. , so that the moving first slider 6 drives the L-shaped block 5 to move. When the moving L-shaped block 5 enters the limiting groove 7 and makes the fixing groove 20 and the fixing block 13 correspond, the pulled T-shaped block 15 is released, so that the spring 16 is no longer restricted and rebounds, so that the rebounding spring 16 drives the connecting rod 12, the fixing block 13, the second slider 14 and the T-shaped block 15 to reset, so that the moving fixing block 13 can be quickly inserted into the fixing groove 20, thereby completing the connection and fixation between the tool body 1 and the tool 2.
