[0022] It should be noted that, since the existing CNC machine tools need to frequently replace the tools when processing the workpiece, the tool installation is usually manually tightened by multiple bolts, which makes it very inconvenient to replace the tools. It is not only time-consuming and laborious, but also increases the manual operation time and slows down the processing process, which cannot meet the use requirements. Therefore, in order to solve the problem that the existing tool installation is usually manually tightened by multiple bolts, which makes it time-consuming and laborious to replace the tools, the present solution is provided with a motor 3 to drive the screw rod 4 to rotate, and the two movable blocks 5 outside the screw rod 4 can be moved and the distance between them can be adjusted, and the vertical plate 6 can be close to or away from the mounting seat, so as to facilitate the disassembly and assembly of the tool 15, effectively improve the disassembly and assembly efficiency of the tool 15, and avoid the situation where the disassembly and assembly efficiency is low due to the installation method that is mostly through bolts, and when the tool 15 is disassembled and assembled out of the tool compartment 1, the insertion rod 17 can be rotated to disassemble and assemble it with the mounting seat 9, so as to facilitate the disassembly and assembly of the tool 15 and the mounting seat 9, and avoid the wear of the tool 15 and the need for overall replacement to increase the cost.

[0025] In this embodiment, the screw rod 4 is driven to rotate by starting the motor 3, so that the two movable blocks 5 outside the screw rod 4 are moved, thereby adjusting the distance between the two vertical plates 6 and making the plug column 11 on one side of the vertical plate 6 away from the positioning groove 10 on one side of the mounting seat 9. The tool 15 can be taken out of the tool compartment 1, and the disassembly and assembly operation of the tool 15 can be completed quickly. When the plug rod 17 is rotated to take it out of the mounting seat 9, it is convenient to disassemble and assemble the tool 15 and the connecting seat 9, so that the worn tool 15 can be replaced, avoiding the need for overall replacement. At the same time, the telescopic sleeve 8 arranged on one side of the vertical plate 6 can play the role of limiting connection when installing the mounting seat 9, preventing the vertical plate 6 from becoming unstable, and the limit block 7 arranged on the front of the vertical plate 6 can further limit the range of movement of the mounting seat 9, thereby further improving the installation stability of the tool 15.

[0027] In this embodiment, it is convenient to disassemble and assemble the cutter 15 and the mounting seat 9, so that the worn cutter 15 can be replaced and repaired, avoiding the situation where the cutter 15 is damaged and needs to be replaced as a whole.

[0028] In a further preferred embodiment of the present invention, Figure 1-3 As shown, one end of the plug post 11 is fixedly connected to one side of the vertical plate 6 , and the vertical plate 6 is movably connected to the mounting seat 9 through the plug post 11 .

[0029] In this embodiment, the mounting seat 9 can be connected and positioned, thereby improving the stability of the tool 15 after completion.

[0030] In a further preferred embodiment of the present invention, Figure 1 As shown, the tool 15 is movably connected to the tool bin 1 through the mounting hole 2, and the diameter of the mounting hole 2 is larger than the diameter of the tool 15 and the diameter of the mounting seat 9 respectively.

[0031] In this embodiment, the tool 15 can be easily disassembled and taken out, and the influence of the small hole diameter on the disassembly and assembly is avoided.

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, a bearing is provided at one end of the screw rod 4, and the screw rod 4 is movably connected to the tool chamber 1 through the bearing.

[0033] In this embodiment, the screw rod 4 can be supported to limit the position, thereby improving its stability during rotation.
