[0040] Working principle:

[0041] First step: Hold the handle 9 and press down. The handle 9 drives the cover plate 3 to press down. The cover plate 3 drives the two clamping blocks 401 to approach each other to clamp the plastic packaging bag. Then, by energizing the heating wire 402, heat is generated, and this heat can seal the plastic packaging bag;

[0042] Second step: While the plastic packaging bag is being sealed, the pressing mechanism 6 can push the second spring plate 604 to fit against the tool rest 501 through the third spring 603 to press and fix the excess part of the plastic packaging bag. The sliding plate 502 is pushed to move by the sliding knob 508. During the movement of the sliding plate 502, the moving plate 11 is used to keep the vertical angle with the plastic packaging bag. At this time, the blade 507 is inserted into the V-shaped groove 7 to cut the packaging bag;

[0043] Step 3: During the downward pressing of the blade 507, the tool holder 506 is pushed by the first spring 504 so that the tool holder 506 can be fully attached to the packaging bag, enabling the blade 507 to completely pierce the plastic packaging bag. After the trimming is completed, the second spring 203 pushes the cover plate 3 to rise for resetting, facilitating the trimming operation again.
