The base plate 101, the uprights 102, and the top plate 103 are welded together, and the slide rods 204 are plugged into the base plate 101 and the top plate 103 respectively. The base plate 101 supports the top plate 103 through the uprights 102, and the sliding frame 301 is inserted between the top plates 103 through the limiting sliding grooves 302 and moves back and forth.

[0026] In this embodiment, the support assembly includes a limiting mechanism, with four sliding rods 204 evenly distributed at the four corners of the limiting mechanism, and springs 205 are provided on the periphery of the sliding rods 204; the limiting mechanism includes a supporting plate 201, with a limiting groove 202 provided in the middle of the supporting plate 201, the limiting groove 202 is rectangular and has a depth of 5 mm, and two handles 203 are symmetrically provided on both sides of the supporting plate 201; the plant sample is placed in the limiting groove 202 of the supporting plate 201, and the supporting plate 201 is pressed down by the handle 203, thereby compressing the spring 205 along the sliding rod 204, and the handle 203 is released, and the elastic force of the spring 205 pushes the supporting plate 201 upward along the sliding rod 204, so that the plant sample is closely attached to the bottom surface of the sliding frame 301;

[0027] In this embodiment, the planing assembly includes a sliding assembly, which is provided with a planing groove 304. The planing grooves 304 are symmetrically arranged with two planing grooves 304 facing outward, and a planer 305 is installed in the planing grooves 304. The sliding assembly includes a sliding frame 301. Two handles 303 are symmetrically arranged on the top of the sliding frame 301, and two limiting slides 302 are symmetrically arranged on both sides of the sliding frame 301.

Finally, the sliding frame 301 is pushed back and forth by the handle 303, so that the planer 305 planes the plant sample to form slices, and discharges them from the planing groove 304.
