[0033] Secondly, while the rotating rod 402 rotates counterclockwise, it drives the rotation of the first synchronous wheel 403. The rotation of the first synchronous wheel 403 drives the rotation of the synchronous belt 4031. The rotation of the synchronous belt 4031 drives the rotation of the second synchronous wheel 4032. The counterclockwise rotation of the second synchronous wheel 4032 drives the rotation of the rotating column 404. The rotation of the rotating column 404 drives the rotation of the first protective plate 405. The first protective plate 405 rotates and closes the bottom end of the die body 1.

[0034] Finally, by rotating the first protective plate 405, the bottom end of the die body 1 can be closed, thereby protecting the bottom end of the die body 1. Through the setting of the same power source, when the rotating rod 402 rotates, it can drive the second protective plate 409 to move through mechanical transmission, thereby closing the inside of the feeding seat 2. Thus, the top and bottom ends of the die body 1 are closed, protecting the inside of the die body 1 and preventing external dust and impurities from entering the die body 1, ensuring the cleanliness of the inside of the die body 1.
