[0060] The slicing gap 64 is in a circular arc shape.

[0061] The controller 23 is provided with an advancing button, a retreating button, a reset button and a switch button. When the vegetable cutter of the utility model 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 starting end of the stroke, so that the user can put vegetables into the feeding groove again. When the vegetable cutter of the utility model is powered on and waits, a 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 starting end or the terminal end of the stroke, and the user can stop pressing at any time. After the user releases the hand, the pushing plate 46 stops sliding, so that the position of the pushing plate 46 is controlled.

[0062] The working principle of the utility model is as follows:

[0063] When the vegetable cutter of the utility model is powered on and on standby, the user opens the feeding cover, then presses the backward button, the pushing motor 42 drives the screw rod 43 to rotate reversely, the screw rod 43 reversely rotating drives the nut sliding block 44 to slide backward, the nut sliding block 44 drives the pushing plate 46 to slide backward, the pushing spring 47 is compressed, until the nut sliding block 44 touches the first micro switch 410, the first micro switch 410 disconnects the circuit of the pushing motor 42, and sends a signal to the controller 23, the pushing motor 42 stops, then the user puts the vegetables into the feeding groove 45, and covers the feeding cover, the fourth micro switch is triggered, and sends a signal to the controller 23, the user presses the switch button, the cutting motor 5 and the pushing motor 42 start, the cutting motor 5 drives the cutting tool to rotate, the pushing motor 42 drives the screw rod 43 to rotate forwardly, the screw rod 43 rotating forwardly drives the nut sliding block 44 to slide forwardly, the nut sliding block 44 no longer pushes the pushing plate 46, the nut sliding block 44 no longer blocks the sliding of the pushing plate 46, the nut sliding block 44 slides forwardly until the second micro switch 49 is triggered, the second micro switch 49 disconnects the circuit of the pushing motor 42, and sends a signal to the controller 23, the pushing motor 42 stops, at the same time, the pushing spring 47 pushes the pushing plate 46 to slide forwardly, the pushing spring 47 is elongated, the pushing plate 46 pushes the vegetables in the feeding groove 45 to slide forwardly, since the cutting tool blocks the vegetables in the feeding groove, the pushing plate 46 cannot slide forwardly quickly, the vegetables in the feeding groove 45 are gradually pushed into the cutting box 3, the cutting tool cuts the vegetables into pieces, the piece-shaped vegetables drop out of the cutting box 3 from the discharging opening, when the pushing plate 46 moves to the front end of the feeding groove 45, the pushing plate 46 stops advancing, at this moment, the vegetables in the feeding groove are all cut by the cutting tool, the pushing plate triggers the third micro switch 411, the third micro switch 411 disconnects the circuit of the cutting motor, and sends a signal to the controller 23, the cutting motor stops, the controller 23 simultaneously sends a signal to the pushing motor 42, the pushing motor 42 drives the screw rod 43 to rotate reversely, the nut sliding block 44 drives the pushing plate 46 to slide backwardly, which is convenient for the user to put the vegetables into the feeding groove again.

[0064] When the user wants to replace the cutting tool, the locking knob can be rotated, then the shell cover 31 is opened, then the locking bolt 66 is unscrewed, then the slicing tool is disassembled, then the dicing tool 8 or the shredding tool 7 is installed on the motor shaft of the cutting motor 5, the locking bolt 66 is screwed again, the dicing tool 8 or the shredding tool 7 is fixed, then the shell cover 31 is covered, 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.

[0065] When the user wants to change the thickness of the slice, the locking knob can be rotated to open the shell cover 31, and then the locking bolt 66 is loosened, and the adjusting nut 65 is rotated, the outer threaded cylinder 68, the movable cutter disc 61 and the movable cutter blade 62 are moved forward or backward, while the fixed cutter blade 63 is not moved, so that the gap size of the slice gap 64 between the movable cutter blade 62 and the fixed cutter blade 63 is changed, thereby realizing the adjustment of the thickness of the slice.
