[0024] Specifically, as shown in the drawings, Figure 2 , 3 the support seat includes a base 12 and a support plate 13, and the cutter is fixed on the base 12; the top surface of the base 12 is provided with guide columns 14 at four corners, the top of the guide column 14 is provided with a limiting block 15, and the support plate 13 is slidingly installed on the guide column 14; the outer portion of the guide column 14 is sleeved with a compression spring 16, and the two ends of the compression spring 16 are respectively abutted with the base 12 and the support plate 13; a plurality of strip-shaped holes for the cutter to pass through are formed on the support plate 13, which include outer strip-shaped holes 17 matched with the outer cutters 8 and inner strip-shaped holes 18 matched with the inner cutters 9; by providing the base 12 and the support plate 13, it is convenient to lay the keratinized gingival slice 4 to be cut on the support plate 13, and during the cutting process, the keratinized gingival slice 4 can be clamped by the mutual abutment of the pressing block 6 and the support plate 13, so as to avoid slipping of the keratinized gingival slice 4 during the cutting process.
[0025] Further, as shown in the drawings, Figure 3 the top surface of the support plate 13 is provided with a positioning groove 19, the shape and size of the positioning groove 19 are matched with the shape and size of the keratinized gingival slice 4 to be cut, and a plurality of strip-shaped holes are formed in the positioning groove 19; the position and size of the positioning groove 19 are matched with the position and size of the pressing block 6; by forming the positioning groove 19 on the top surface of the support plate 13, it is convenient to position the keratinized gingival slice 4 to be cut when laid flat, thereby improving the cutting efficiency.
[0026] Further, the abutting surfaces of the support plate 13 and the pressing block 6 are uniformly provided with anti-skid patterns, which can further prevent the keratinized gingival slice 4 from slipping during the cutting process.
[0027] Specifically, as shown in the drawings, Figure 1 the telescopic end of the telescopic mechanism 5 is provided with a push plate 20, the four corners of the push plate 20 are slidingly installed on the guide support column 3 through linear bearings 21, and the pressing block 6 is installed below the push plate 20; by sliding cooperation of the push plate 20 and the guide support column 3, the movement of the pressing block 6 can be guided and constrained, avoiding horizontal shaking of the pressing block 6 during the pressing process, so as to ensure that the cutter on the support seat can accurately sink into the accommodating groove 7 on the bottom surface of the pressing block 6 after passing through the keratinized gingival slice 4.

[0030] Firstly, the keratinized gingival slice 4 to be cut is placed in the positioning groove 19 on the top surface of the support plate 13, and then the telescopic mechanism 5 is controlled to drive the pressing block 6 to move downward; when the pressing block 6 has not abutted against the support plate 13, the support plate 13 is abutted against the limiting block 15 by the elastic force of the compression spring 16 (the support plate 13 is prevented from slipping off the top of the guide column 14 by the limiting block 15), at this time, the top of the cutter just extends into the strip-shaped hole; when the pressing block 6 continues to move downward to abut against the support plate 13, the support plate 13 moves downward to press the compression spring 16, and at the same time, the compression spring 16 also applies an upward supporting force to the support plate 13 so that the support plate 13 clamps the keratinized gingival slice 4 in cooperation with the pressing block 6 (at this time, the cutter just completely passes through the strip-shaped hole); with the continuous downward pressing of the pressing block 6, the cutter on the base 12 passes through the strip-shaped hole on the support plate 13 to cut the clamped keratinized gingival slice 4, and the cutter passing through the keratinized gingival slice 4 will sink into the storage groove in the bottom surface of the pressing block 6.
[0031] After the cutting is completed, the telescopic mechanism 5 is controlled to drive the pressing block 6 to move upward, and with the continuous upward movement of the pressing block 6, the support plate 13 also gradually rises back to the original position under the action of the compression spring 16, and the cutter is gradually withdrawn from the pressing block 6, the keratinized gingival slice 4 and the support plate 13, and when the pressing block 6 rises to a certain height above the support plate 13, the cut keratinized gingival slice 4 can be taken out from the positioning groove 19 of the support plate 13, as shown in Figure 4 The two ends of the slice are stretched along the length direction of the keratinized gingival slice 4, and the reticular keratinized gingival slice 4 is obtained, as shown in Figure 5 The covering area of the stretched reticular keratinized gingival slice 4 is obviously improved compared with the covering area of the keratinized gingival slice 4 before cutting, so that the increment of the keratinized gingival is realized.
[0032] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
