[0023] In an embodiment of the present utility model, on the opposite surfaces of the two rotating shaft mounting seats 9, there are respectively provided embedding grooves matching the rotating shaft bearings 10. The inner ring of the rotating shaft bearing 10 is fixedly connected to the outer surface of the rotating shaft 11. The rotating shaft bearing 10 embedded in the embedding groove on one side of the rotating shaft mounting seat 9 is used to maintain the support of the rotating shaft mounting seat 9 for the rotating cutting frame 12. The number of the fastening pieces 5 is several, and between the rotating shaft mounting seat 9 and the bottom plate 3, between the slicing backing plate 13 and the backing plate mounting block 2, and between the length adjusting block 1 and the backing plate mounting block 2, they are all connected through the fastening pieces 5. The several fastening pieces 5 realize the connection of multiple components in the slicing mechanism. One end of the backing plate mounting block 2 is provided with a placement groove for the length adjusting block 1, and in the middle of one end of the length adjusting block 1, there is a long slot matching the diameter of the lower end of the fastening piece 5. The length adjusting block 1 is stuck in the placement groove to prevent it from tilting left and right. At the same time, after the lower end of the fastening piece 5 passes through the long slot and its upper end contacts the length adjusting block 1, the length adjusting block 1 after adjusting the position is fixed. In the middle of the slicing backing plate 13, there is a card slot matching the silicone strip, and one end of the slicing backing plate 13 is connected with an extension block at the same height as the bottom of the card slot.
