Description

Technical Field

[0001] The utility model relates to a slicer, in particular to a sliding slicer which is convenient for clamping. Background Art

[0002] The stalks of crops are generally round in shape, and the mechanical properties of the stalks depend on the morphological structure of the cells. The cells that have a greater impact on the mechanical properties of crops include thin-walled cells, thick-walled cells, fibers, stone cells, tubules and vessels. Basic parenchyma cells usually have large cell cavities, thin cell walls, and are generally polyhedrons with almost equal diameters. Thick-walled cells are long columns with polygonal cross-sections. The cell walls are generally thickened at the corners of adjacent cells, and this thickening is of the nature of the primary wall. Crop fibers are slender cells with pointed ends and spindle-shaped. Stone cells are of various shapes, most of which are nearly spherical or polyhedral, and there are also short rods or branches, and the sizes are not uniform. Tracheids are hollow, tubular, thick-walled cells with slender shapes, sharp ends, overall spindle-shaped, polygonal cross-sections, and the long axis is parallel to the tree axis. Common shapes of tracheal cells include drum-shaped, spindle-shaped, cylindrical, rectangular, etc. The cell morphological and structural characteristics, such as cell orientation, cell cavity size, cell wall thickness and other structural parameters, can be obtained to establish the cell morphological and structural model. Slices of different crop tissues, combined with microscopes to observe the microstructure of the tissues, analyze the morphology, distribution and arrangement characteristics of the constituent cells, which is of great reference significance for establishing a reasonable tissue model.

[0003] The current sliding slicer clamp assembly is a two-sided parallel mechanical clamp. For example, the utility model patent with the authorization announcement number CN212825704U discloses an improved structure of a paraffin slicer chuck. Although the paraffin slicer solves the problem that the current paraffin slicer chuck cannot adjust the horizontal angle and pitch angle of the fixed paraffin raw material to match the cutting tool, it also has the following shortcomings:

[0004] When clamping, place the paraffin raw material sample to be sliced ​​in the middle of the clamp plate, then adjust the telescopic push rods that are movably engaged in the installation holes so that the top of each telescopic push rod touches the side of the paraffin raw material, and then lock the telescopic push rods through the locking screws, so that the paraffin raw material sample is fixed in the round hole in the middle of the clamp plate. The above operation is not only cumbersome and difficult to clamp, but also the relative clamping position of the sample is judged by the naked eye, which is not accurate enough.
