It should be noted here that the top of the movable shaft 11 is always located in the guide sleeve 10 and will not fall out of the guide sleeve 10;

[0023] Secondly, if Figure 1 and Figure 2 As shown, the transmission mechanism includes a connecting shaft 27, which is radially connected to the side of the movable shaft 11 between the guide sleeve 10 and the mounting seat 16, and the movable shaft 11 extends toward the driving motor 8;

[0024] The end of the movable shaft 11 is rotatably connected to one end of the driving arm 26, and the other end of the driving arm 26 is rotatably connected to the edge of the turntable 9. The two are specifically connected through a rotating shaft, and the turntable 9 is coaxially arranged on the rotating shaft of the driving motor 8, so that when the driving motor 8 rotates, it can drive the turntable 9 to rotate, and the turntable 9 drives the driving arm 26 to move up and down, so that the driving arm 26 drives the movable shaft 11 to reciprocate up and down, and the blade 21 also moves up and down quickly.

[0025] Among them, the bottom of the driving motor 8 is arranged on the motor support 7 to support the driving motor 8. The motor support 7 and the mounting seat 16 are an integrated structure. A mounting shaft 25 is provided at one end of the driving motor 8 away from the transmission mechanism. The driving motor 8 is a double-axis motor.
