The push force is transmitted to the pressure block 87, which can make the pressure block 87 press the plastic package tightly, which can realize the positioning and cutting of the plastic package, improve the cutting effect, and also avoid the inconvenience of manually positioning the plastic package. After the positioning is completed, as the fixed seat 6 continues to move down, the cutter 10 contacts the plastic package, and the cutting of the plastic package is completed.

[0026] When it is necessary to disassemble the cutter 10, simply pull down the cutter holder 7. The cutter holder 7 will move the connecting block 95 downwards. The connecting block 95 will slide along the arc-shaped block 93 and press against the arc-shaped block 93. The arc-shaped block 93 will move away from the connecting block 95. The connecting block 95 will drive the ball bearing 94 to roll. At the same time, the connecting block 95 will drive the slide rod 91 to move horizontally and press against the second spring 92, which can separate the arc-shaped block 93 from the connecting block 95. Then the connecting block 95 can be pulled out from the fixed seat 6, which is convenient for disassembling the cutter holder 7 and the cutter 10. After the cutter 10 becomes dull, it is convenient to disassemble and grind the cutter 10.
