[0055] The center hole of the movable cutter disc 61 is sleeved on the outer side of the outer threaded cylinder 68 and is in interference fit with the outer threaded cylinder 68.

[0056] The adjusting nut 65 comprises an inner ring 613 and an outer ring 612 which are connected and arranged inside and outside, the inner side wall of the outer ring 612 is provided with internal threads, the outer ring 612 is threadedly connected with the outer threaded cylinder 68, the end surface of the inner ring 613 is abutted against the end surface of the center shaft sleeve 610, and the locking bolt 66 penetrates through the inner ring 613 and is abutted against the end surface of the center shaft sleeve 610.

[0057] The inner end surface of the locking bolt 66 is provided with a locking screw 69 which is threadedly connected with the screw hole 52 on the motor shaft 51, and the inner end surface of the locking bolt 66 is abutted against the end surface of the center shaft sleeve 610. The locking bolt fixes the adjusting nut 65, the movable cutter disc 61 and the fixed cutter disc 67 on the motor shaft 51.

[0058] The adjusting nut 65 is a plastic nut, and the plastic nut is easy to deform, so when the adjusting nut 65 and the locking bolt are assembled, the adjusting nut 65 can be forcibly pressed into the inner ring by overcoming the obstruction of the first anti-drop reverse buckle 614.

[0059] The inner side wall of the inner ring of the adjusting nut 65 is provided with the first anti-drop reverse buckle 614, the outer side wall of the locking bolt 66 is provided with the second anti-drop reverse buckle 613 corresponding to the first anti-drop reverse buckle 614, and the first anti-drop reverse buckle 614 is matched with the second anti-drop reverse buckle 613.

[0062] The slice seam 64 is in a circular arc shape.

[0063] The controller 23 is provided with an advancing button, a retreating button, a reset button and a switch button. When the vegetable cutter is powered on and waits, a user presses the reset button, the pushing motor 42 drives the nut sliding block 44 to slide backward to the beginning of the stroke, so that the user can put vegetables into the feeding groove again. When the vegetable cutter is powered on and waits, the user presses the advancing button or the retreating button, the pushing motor 42 drives the nut sliding block 44 to advance or retreat to the beginning or the end of the stroke, the user can stop pressing at any time, and after the user releases the hand, the pushing plate 46 stops sliding, so that the position of the pushing plate 46 is controlled.

[0064] The working principle of the utility model is:

[0065] When the vegetable cutter of this utility model is powered on and in standby mode, the user opens the feeding cover and then presses the reverse button. The pusher motor 42 drives the lead screw 43 to rotate in the opposite direction. The reverse rotation of the lead screw 43 drives the nut slider 44 to slide backward. The nut slider 44 drives the pusher plate 46 to slide backward, and the pusher spring 47 is compressed until the nut slider 44 touches the first micro switch 410. The first micro switch 410 disconnects the circuit of the pusher motor 42 and sends a signal to the controller 23, stopping the pusher motor 42. Then, the user puts the vegetables into the feeder. The material is placed in the feed trough 45, and then the feeding cover is closed. The fourth micro switch is triggered and sends a signal to the controller 23. The user presses the switch button, and the cutting motor 5 and the pushing motor 42 start. The cutting motor 5 drives the cutting blade to rotate, and the pushing motor 42 drives the lead screw 43 to rotate forward. The forward rotation of the lead screw 43 drives the nut slider 44 to slide forward. The nut slider 44 no longer pushes against the pushing plate 46, and the nut slider 44 no longer obstructs the sliding of the pushing plate 46. The nut slider 44 continues to slide forward until the second micro switch 49 is triggered. The second micro switch 49 disconnects the circuit of the pusher motor 42 and sends a signal to the controller 23, stopping the pusher motor 42. At the same time, the pusher spring 47 pushes the pusher plate 46 forward, extending the pusher spring 47. The pusher plate 46 pushes the vegetables in the feed trough 45 forward. Because the cutting blade blocks the vegetables in the feed trough, the pusher plate 46 cannot slide forward quickly. The vegetables in the feed trough 45 are gradually pushed into the cutting box 3. The cutting blade cuts the vegetables into slices, and the sliced ​​vegetables fall out of the cutting box 3 from the discharge port. When the pusher plate 46 moves to the front end of the feeding trough 45, the pusher plate 46 stops moving forward. At this time, the vegetables in the feeding trough have been cut by the cutting blade. The pusher plate triggers the third micro switch 411, which disconnects the circuit of the cutting motor and sends a signal to the controller 23. The cutting motor stops. The controller 23 sends a signal to the pusher motor 42 at the same time. The pusher motor 42 drives the lead screw 43 to rotate in the opposite direction. The nut slider 44 drives the pusher plate 46 to slide backward, making it convenient for the user to put vegetables into the feeding trough again.

[0066] When the user wants to replace the cutting blade, they can rotate the locking knob, then open the cover 31, then unscrew the locking bolt 66, then remove the slicing blade, then install the dicing blade 8 or shredding blade 7 onto the motor shaft of the cutting motor 5, tighten the locking bolt 66 again to fix the dicing blade 8 or shredding blade 7, then close the cover 31, the fifth micro switch 37 is triggered, the fifth micro switch connects the circuit of the cutting motor 5 and sends a signal to the controller 23.

[0067] When a user wants to change the slicing thickness of the cutting blade, they can rotate the locking knob to open the cover 31, then loosen the locking bolt 66, and then rotate the adjusting nut 65. The rotation of the adjusting nut 65 causes the external threaded cylinder 68, the movable cutter head 61, and the movable blade 62 to move forward or backward, while the fixed blade 63 remains stationary. This changes the size of the slicing gap 64 between the movable blade 62 and the fixed blade 63, thereby adjusting the slicing thickness.
