[0039] Working principle: When the device is used, first adjust the spacing of multiple sets of tool bodies 7 according to needs. When adjusting, first rotate the positioning ring 81 to drive the positioning block 82 to move. The moving positioning block 82 will release the extrusion of the inclined surface of the connecting block 83. At this time, the reaction force of the connecting spring 86 will push the moving block 84, the positioning plate 85 and the limit block 87 to move upward. The limit block 87 moving upward will be separated from the limit groove 801 to release the limit on the tool body 7. After the limit is released, move the multiple sets of tool bodies 7 to the appropriate position. After the position of the tool body 7 is adjusted, rotate the positioning ring 81 in the opposite direction to drive the positioning Block 82 moves in the opposite direction, and the positioning block 82 moving in the opposite direction will squeeze the inclined surface of the upper surface of the connecting block 83, and the connecting block 83 will be squeezed to move downward, and the connecting block 83 moving downward will squeeze the moving block 84, and the moving block 84 will move downward, and the moving block 84 moving downward will squeeze the connecting spring 86 to generate a reaction force, and the moving block 84 moving downward will drive the positioning plate 85 and the limit block 87 to move downward, and the limit block 87 moving downward will be plugged into the limit groove 801 to limit the tool body 7, and under the influence of the self-locking property of the thread groove, the position of the tool body 7 will be fixed, which can ensure the stability of the device.

[0040] In the process of use, the electric telescopic rod 2 can be driven to adjust the height of the slider 4, so as to change the position of the motor 3, the shaft 6 and the tool body 7, so as to change the cutting depth. After a period of use, if the tool body 7 needs to be disassembled and replaced, the shift block 52 can be moved toward the middle part of the shaft 6. When the shift block 52 moves, it will drive the clamping block 54 to move synchronously. The moving clamping block 54 will squeeze the compression spring 53 to generate a reaction force, and will be separated from the clamping groove 501, so that the shaft 6 and the round After the tube 51 is disassembled and the rotating shaft 6 is removed, the positioning ring 81 can be rotated to drive the limit block 87 and the limit groove 801 to disengage and release the limit on the tool body 7, and then the tool body 7 can be removed. During the removal process of the tool body 7, the shift block 52 will pass through the square groove 502. After the tool body 7 is removed, the tool body 7 to be installed is installed to the specified position on the rotating shaft 6. After adjustment, the positioning ring 81 is rotated in the opposite direction to drive the limit block 87 and the limit groove 801 to engage and limit the tool body 7 to ensure the stability of the tool body 7.

[0041] Then move the shift block 52 toward the center of the rotating shaft 6 to drive the clamping block 54 to move synchronously. The moved clamping block 54 will retract into the rotating shaft 6 and squeeze the compression spring 53 to generate a reaction force. Then move the rotating shaft 6 and align the clamping block 54 with the clamping slot 501. After alignment, release the shift block 52. The reaction force of the compression spring 53 will push the clamping block 54 to move. The clamping block 54 will be plugged into the clamping slot 501 to limit the rotating shaft 6, thereby completing the replacement of the tool body 7.
