[0023] like Figure 1 - Figure 3 As shown, the connecting component includes a connecting column 3 and a fixing thread 4, the bottom end of the connecting column 3 is fixedly connected to the top end of the button ring 2, the fixing thread 4 is arranged on the outside of the connecting column 3, the connecting column 3 is designed to cooperate with the fixing thread 4, so as to facilitate the fixing of the blade 1 to other devices, the top end of the clamping block 7 is in contact with the bottom end of the blade 5, the outer side of the clamping block 7 is slidably connected to the inside of the blade body 1, the clamping block 7 is designed to facilitate the fixing of the blade 5, the front side of the push spring 8 is fixedly connected to the rear side of the clamping block 7, and the push spring 8 is designed to push the clamping block 7 to fix the blade 5.

[0024] The outer side of the toggle block 9 is slidably connected to the inside of the toggle groove 6. The toggle block 9 is designed to facilitate the toggle of the card block 7, so that the card block 7 can squeeze the push spring 8 while completely entering the inside of the toggle groove 6 without blocking the blade 5. The reinforcement component includes a threaded rod 10, a knob 11, a rotating plate 12 and an extrusion block 13. The outer side of the threaded rod 10 is threadedly connected to the inside of the blade body 1. The threaded rod 10 is designed to drive the extrusion block 13 to tightly engage with the blade 5 by rotation. The rear end of the knob 11 is fixedly connected to the front side of the threaded rod 10. The knob 11 is designed to facilitate the rotation of the threaded rod 10.

[0025] The front side of the rotating piece 12 is fixedly connected to the rear end of the threaded rod 10. The design of the rotating piece 12 is to facilitate the connection between the rotating button 11 and the extruding block 13. The outer side of the extruding block 13 is slidably connected to the inside of the blade body 1. The design of the extruding block 13 is to fit tightly with the blade 5 under the drive of the threaded rod 10 to reinforce the blade 5.

The design of the extruding block 13 is to fit tightly with the blade 5 under the drive of the threaded rod 10 to reinforce the blade 5.

[0026] Working principle: when the blade 5 needs to be replaced, the knob 11 is first turned to rotate the threaded rod 10, and then the extrusion block 13 is driven so that the extrusion block 13 is no longer tightly fitted with the blade 5. At this time, the toggle block 9 can be manually moved, thereby driving the card block 7 to no longer block the blade 5 while squeezing the push spring 8. At this time, the blade 5 can be taken out from the inside of the blade body 1, and the new blade 5 is reinserted into the inside of the blade body 1. The blade 5 will also squeeze the card block 7 so that the card block 7 will not block the blade 5. When the blade 5 is placed in a suitable position, the blade 5 will no longer squeeze the card block 7. At this time, the card block 7 will rise to fix the blade 5. Then the knob 11 is twisted by hand to drive the extrusion block 13 to fit tightly with the blade 5 through the threaded rod 10, thereby reinforcing the blade 5. By quickly replacing the blade 5, the replacement of the entire milling cutter is avoided, reducing costs. At the same time, different blades 5 can be replaced according to different needs, thereby improving the flexibility of use.
