Through the detachable structure between the cutter head 1, the fixing rod 3 and the sleeve rod 9, when the cutter head 1 is damaged, the damaged cutter head 1 is replaced to avoid replacing the entire crushing milling cutter, which not only saves costs but also facilitates storage. Embodiment 2

[0024] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0025] The cutter head 1 is detachably connected to the fixing rod 3 through the connecting rod 2 and the screw hole 5, and the connecting rod 26 forms a sliding structure with the sleeve rod 9 through the mounting hole 14 and the screw hole 28. The cutter head 1 and the fixing rod 3 are detachable, and the cutter head 1 is fixed to the fixing rod 3 through the connecting rod 2, the connecting hole 4, the screw hole 15, and the screw, so that it is convenient to replace the old cutter head 1 when the crushing milling cutter head 1 is damaged, avoiding the replacement of the entire crushing milling cutter and saving the replacement cost. The connecting rod 26 and the sleeve rod 9 are slidable and detachable, so that the connecting rod 26 can be moved inside the sleeve rod 9 so that any screw hole 28 on the connecting rod 26 corresponds to the screw hole 28 on the sleeve rod 9, and then it is fixed by the bolt 10, and the length of the crushing milling cutter is adjusted, which is convenient for processing honeycomb materials at different depths. At the same time, the split crushing milling cutter can also be convenient for storage.

[0026] A clamping groove 11 is formed on the outer surface of one end of the sleeve rod 9 , and a positioning hole 12 is formed on one side of one end of the sleeve rod 9 . The positioning hole 12 and the positioning rod 24 facilitate positioning and installation between the sleeve rod 9 and the installation head 15 .

[0027] A mounting head 15 is arranged on the outer side of the sleeve rod 9, and a second mounting hole 16 is opened at one end of the mounting head 15, through which the crushing milling cutter can be easily installed.

[0028] A positioning rod 24 is fixed to the inner wall of the second mounting hole 16, a slide groove 17 is provided inside the mounting head 15, and a slide groove 21 is provided on one side of the slide groove 17, so that the clamping block 20 and the limiting rod 23 can be easily moved inside thereof through the slide groove 17 and the slide groove 21.

[0029] A return spring 18 is fixed inside the slide groove 17, one end of the return spring 18 is fixedly connected to a connecting plate 19, one end of the connecting plate 19 is fixed to a clamping block 20, and by pressing one end of the clamping block 20, the connecting plate 19 and the clamping block 20 can move in the slide groove 17 through the return spring 18, so that the other end of the clamping block 20 clamps the clamping groove 11 on the sleeve rod 9.

[0030] A return spring 22 is fixed inside the second slide groove 21, and a limit rod 23 is fixed at one end of the return spring 22. After clamping the sleeve rod 9, the return spring 22 inside the second slide groove 21 pushes the limit rod 23 to limit the position of the connecting plate 19, and the clamping block 20 continues to clamp the clamping groove 11 to achieve the installation and disassembly of the crushing milling cutter.

[0031] Working principle: Before using the crushing milling cutter, first insert the connecting rod 2 at one end of the cutter head 1 into the connecting hole 4 of the fixing rod 3, and then fix the fixing rod 3 and the connecting rod 2 through the screw hole 5 to fix the cutter head 1 and the fixing rod 3. The structure of fixing the fixing rod 3 and the connecting rod 2 through the screw can quickly replace the old cutter head 1 when the cutter head 1 is damaged. A connecting rod 26 is fixed to one end of the fixing rod 3. The connecting rod 26 is installed to the inside of the mounting hole 14 at one end of the sleeve rod 9 through the clamping block 7 and the clamping groove 13, and then the connecting rod 26 is fixed in the sleeve rod 9 through the bolt 10 and the screw hole 28 to ensure the stability of the connection between the connecting rod 26 and the sleeve rod 9. There are three screw holes 28 on the outer surface of the connecting rod 26. The three screw holes 28 can be used to move the connecting rod 26 when the length of the crushing milling cutter needs to be adjusted. Any one of the screw holes 8 corresponds to the screw hole 8 on the sleeve rod 9, and the length of the crushing milling cutter is adjusted to change the overall length of the crushing milling cutter. After the overall length of the cutter head 1 and the crushing milling cutter is fixed and adjusted, the other end of the sleeve rod 9 is installed in the mounting head 15 through the positioning rod 24, the positioning hole 12 and the mounting hole 16, and then one end of the clamping block 20 is pressed, and the clamping block 20 and the connecting plate 19 move in the slide groove 17 through the return spring 18, so that the other end of the clamping block 20 clamps the clamping groove 11 of the sleeve rod 9. When the clamping block 20 clamps the clamping groove 11, the limiting rod 23 moves in the slide groove 21 through the return spring 22, so that one end of the limiting rod 23 moves into the slide groove 21, and is stuck above the connecting plate 19 to limit the position of the connecting plate 19 and the clamping block 20, so that the clamping block 20 can always fix the sleeve rod 9.
