This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0028] Reference Figures 1 to 6 As shown, a cyclone milling cutter that is easy to disassemble and assemble, the milling cutter includes a tool handle 3, a clamping seat 8 set at one end of the tool handle 3, a through groove 4 is opened in the tool handle 3, a clamping slot 9 that is connected to the through groove 4 is opened in the clamping seat 8, and a milling cutter head 18 is clamped in the clamping slot 9.

[0029] A rivet 1 is threadedly connected to the end of the tool handle 3 remote from the receiving seat 8. A notch 2 is provided at one end of the rivet 1. A threaded hole 6 is also formed in the tool handle 3, communicating with the through-slot 4. One end of the rivet 1 is provided with a thread 5 that mates with the threaded hole 6. In this embodiment, the rivet 1 allows the tool handle 3 to be secured to the milling machine head. The notch 2 allows an operator to tighten the rivet 1 and tool handle 3 using an external wrench through the notch 2 during installation.

[0030] A fixing groove 10 communicating with the through groove 4 is also provided in the tool handle 3, and a fixing part 11 is fixedly installed in the fixing groove 10. A plurality of elastic parts 12 are arranged at intervals on one end of the fixing part 11 facing the card slot 9, and a pressure block 13 is connected to the other end of the plurality of elastic parts 12. Furthermore, guide grooves 15 are symmetrically arranged at intervals along the length direction of the clamping seat 8. The guide groove 15 is communicated with the card slot 9, and one end of the guide groove 15 passes through the clamping seat 8. The clamping seat 8 also has symmetrically spaced limit grooves 17 along the length direction.

[0031] In this embodiment, the limiting groove 17 is spaced apart from the guide groove 15 , and the limiting groove 17 is communicated with the clamping groove 9 .

[0032] An annular groove 16 communicating with the clamping groove 9 , the limiting groove 17 and the guide groove 15 is provided in the tool handle 3 along its circumferential direction. A clamping block 14 movable in the limiting groove 17 is provided at opposite ends of the pressure block 13 .

[0033] Two opposite ends of the milling cutter head 18 are provided with clamping blocks 19 that match the limiting grooves 17 .

[0034] Positioning grooves 7 are also provided at intervals on the outer end surface of the tool handle 3. In this embodiment, by providing the positioning grooves 7, when installing the tool handle 3, the tool handle 3 is aligned with the latch portion at the bottom of the machine head so that the latch portion engages with the positioning grooves 7 to position the tool handle 3.

[0035] In the above embodiment, when installing the milling cutter head 18, the operator holds the milling cutter head 18, aligns the milling cutter head 18 with the slot 9 in the connector 8, and passes the second block 19 on the milling cutter head 18 through the guide slot 15 to the annular slot 16. During this process, the milling cutter head 18 pushes the pressing block 13 to move, so that the first block 14 on the pressing block 13 moves in the limiting slot 17, pushing the pressing block 13 to the end. Then the operator rotates the milling cutter head 18. During this rotation process, the second block 19 rotates in the annular slot 16, and then the second block 19 is rotated to the limiting slot 17, and then the second block 19 is slid into the limiting slot 17. Then, the milling cutter head 18 is released, and the pressing block 13 is elastically supported by the elastic member 12 to perform a reset movement. At this time, the pressing block 13 squeezes the milling cutter head 18, thereby fixing the milling cutter head 18, and the installation of the milling cutter head 18 is completed. Vice versa.

During this process, the milling cutter head 18 will push the pressure block 13 to move, so that the card block 14 on the pressure block 13 moves in the limit groove 17, and pushes the pressure block 13 to the end. Then the operator rotates the milling cutter head 18. During this rotation process, the card block 2 19 rotates in the annular groove 16, and then the card block 2 19 is rotated to the limit groove 17, and then the card block 2 19 is slid into the limit groove 17. Then the milling cutter head 18 is released, and the pressure block 13 is elastically supported by the elastic member 12 to perform a reset movement. At this time, the pressure block 13 will squeeze the milling cutter head 18, thereby fixing the milling cutter head 18 and installing the milling cutter head 18. And vice versa.
