When the rack 2 863 moves, it drives the fixed plate 864 to move. When the fixed plate 864 moves, it pulls the tension spring 865 to move. The rack 2 863 drives the connecting block 789 to move. When the connecting block 789 moves, it drives the rack 1 787 to move. When the rack 1 787 moves, it drives the gear 1 786 to rotate. When the gear 1 786 rotates, it drives the round rod 1 782 to rotate. When the round rod 1 782 rotates, it drives the bevel gear 1 783 to rotate. When the bevel gear 1 783 rotates, it drives the bevel gear 2 784 to rotate. When the bevel gear 2 784 rotates, it drives the rotating rod 1 785 to rotate.

When the electromagnetic block 8695 moves, it drives the push block 8694 to move. When the push block 8694 moves, it drives the limit rod 8692 to move. When the limit rod 8692 moves, it squeezes the spring 8693. The push block 8694 moves to push the limit block 8696 to move upward, so that the limit block 8696 extends into the slot 868, and then the rotation of the motor 82 is stopped. 8. The material is introduced into the storage bin 61 along the storage box 77. When the material is poured out, the electromagnet 867 is de-energized, so that the electromagnet 867 no longer adsorbs the second electromagnet block 8695. The second spring 8693 loses its force and pushes the limit rod 8692 to move. When the limit rod 8692 moves, it drives the push block 8694 to move. When the push block 8694 moves, the support for the limit block 8696 is cancelled, so that the limit block 8696 moves out of the slot 868. After the tension spring 865 loses its force, it releases its elastic potential energy to pull the fixed plate 864 to move. When the fixed plate 864 moves, it drives the second rack 863 to move. 9. When the rack 2 863 moves, it drives the gear 4 862 to move. The gear 4 862 rotates and drives the rotating rod 4 861 to rotate. When the rotating rod 4 861 rotates, it drives the rotating rod 2 83 to rotate through the conversion mechanism 85. When the rotating rod 2 83 rotates, the adjusting mechanism 84 controls the adjusting plate 63 to reset. 10. When the rack 2 863 moves, it drives the rack 1 787 to move through the connecting block 789. When the rack 1 787 moves, it drives the gear 1 786 to rotate. When the gear 1 786 rotates, it drives the round rod 1 782 to rotate, so that the movable plate 76 can be controlled to rotate, so that the storage box 77 moves back to its original position and waits for the next use.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
