The limiting member is movably connected in the countersunk hole 18. A hexagonal groove is vertically formed on the top surface of the rotating block 20. A threaded hole 17 is vertically penetrated through the top surface of each of the two support plates 7. The threads of the two threaded holes 17 are opposite in direction. Each groove 11 has a through hole 9 that passes vertically through it. The inner wall of the mounting groove 4 has multiple equidistant annularly distributed positioning grooves 8. Each end face of the two support plates 7 is fixedly connected to a positioning block 13. The positioning block 13 moves through the through hole 9 and is inserted into the positioning groove 8. The top surface of each of the two support plates 7 has two mirror-symmetrical guide holes 15 that pass vertically through it. Each guide hole 15 has a guide rod 6 that slides axially in it. The guide rod 6 is vertically fixed between the mounting groove 4 and the insert block 14. Each guide rod 6 has a spring 16 that is sleeved on its outer edge.

[0024] The limiting component includes a countersunk hole 19 that penetrates one end face of bolt 5. The countersunk hole 19 is eccentrically positioned on the top surface of bolt 5. A receiving groove 22 communicating with the countersunk hole 19 is vertically formed at the lower end of bolt 5.

A compressed spring 25 is fixedly connected to the bottom surface of the threaded groove 26. The spring 25 is fixed to the bottom surface of the push plate 24. Two mirror-symmetrical sliding grooves are vertically opened on the inner wall of the threaded groove 26. A slider is slidably connected in each sliding groove.

[0025] By connecting the cutter head 2 to the mounting groove 4 inside the drive shaft 3 via the connecting shaft 10, and movably connecting the locking member connected to the connecting shaft 10 in the mounting groove 4, it is convenient to disassemble and assemble the cutter head 2 and the drive motor 1, and to disassemble and repair the damaged cutter head 2. A limiting member is movably connected to the bolt 5 on the locking member, and the limiting member is movably connected to the countersunk hole 18, so as to fix the bolt 5 and prevent the bolt 5 from loosening when the drive shaft 3 rotates.

[0026] Working principle: When disassembling the cutter head 2 and the drive motor 1, firstly rotate the rotating block 20. The rotating block 20 drives the threaded block 23 to rotate through the connecting rod 21, so that the threaded block 23 moves from the threaded groove 26 to the receiving groove 22. At the same time, the spring 25, which is in a compressed state, returns to its original state. When the spring 25 returns to its original state, it pushes the push plate 24 to rise, so that the top surface of the push plate 24 is flush with the top surface of the countersunk hole 18, so that the limit of the bolt 5 disappears. Then rotate the bolt 5, and the bolt 5 drives the two support plates to move relative to each other, so that the positioning block 13 leaves the positioning groove 8 and is put into the groove 11. At the same time, the support plate 7 presses the spring 16 to compress. Then the cutter head 2 together with the connecting shaft 10 is pulled out from the mounting groove 4 in the drive shaft 3, thus completing the disassembly of the cutter head 2.

[0027] When assembling the cutter head 2, insert the connecting shaft 10 into the mounting groove 4, so that the insert block 14 is inserted into the slot 12, and the support plate 7 is inserted into the groove 11. Then, rotate the bolt 5 in the opposite direction, so that the two support plates 7 move in opposite directions. The support plate 7 drives the positioning block 13 to extend out of the same height and insert into the positioning groove 8. At the same time, the spring 16 returns to its original position. At this time, the threaded block 23 will be aligned with the threaded groove 26. Then, rotate the rotating block 20. When rotating the rotating block 20, first apply a downward pressure to the rotating block 20, so that the rotating block 20 passes through... The connecting rod 21 drives the threaded block 23 to descend slightly, causing the threaded block 23 to push the support plate 7 to descend slightly. At the same time, the second spring 25 is compressed slightly, causing the threaded block 23 to abut against the inlet end of the threaded groove 26. Then, the rotating block 20 is rotated to screw the threaded block 23 into the threaded groove 26. At the same time, the push plate 24 descends and pushes the second spring 25 to be further compressed until the second spring 25 is compressed to its limit position, thereby completing the locking of the bolt 5 and preventing the bolt 5 from loosening when the drive shaft 3 rotates.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
