Plant specimen holding device

Abstract

A plant specimen holding device comprises a supporting assembly, a placing assembly and a holding assembly. The placing assembly comprises a placing plate body and a partition member. The partition member partitions the placing plate body into a specimen holding area to be pressed and a specimen holding area to be pressed. A pressure holding assembly includes a pressure bearing plate, rotating shaft, press the handrail and counterweight, Before pressing fresh plants into specimens, Fresh plants need to be cleaned up in the area where specimens are to be pressed, and put it in a certain shape,which can then be positioned on the holding assembly for pressing, Fresh plants of a fixed type are placed on a pressure plate, Pull the holding handrail, The pressure holding plate is brought into contact with the pressure bearing plate, so that fresh plants are pressed between the pressure holding plate and the pressure bearing plate, and under the gravity of a counterweight block at the other end of the pressure handrail, the pressure holding plate tightly presses fresh plants on the pressure bearing plate, so that the operation of preparing a specimen is simple, and the pressed specimen can be molded more smoothly.

Description

technical field [0001] The invention relates to the technical field of placing racks, in particular to a pressing device for plant specimens. Background technique [0002] At present, making plant specimens is one of the powerful means to solve the problem of botany teaching aids. If there are living plants in classroom teaching, it will be more conducive to students' deepening understanding. Using plant specimens can avoid the regional and seasonal restrictions of some plants. , Plant specimens preserve the shape and color of plants for future re-observation and research, and a few plant specimens are also valuable for collection. [0003] At present, the most common of plant specimens is wax leaf specimens. Plant specimens are made by pressing fresh plant materials with absorbent paper to dry and then binding them on white hard paper (this paper is called table paper). When plant specimens, the absorbent paper is usually placed on a flat table top, and then pressed on it ...

Problems solved by technology

[0003] At present, the most common of plant specimens is wax leaf specimens. Plant specimens are made by pressing fresh plant materials with absorbent paper to dry and then binding them on white hard paper (this paper is called table paper). When plant specimens, the absorbent paper is usually placed on a flat table top, and then pressed on it with a flat weight, so that the plant specimens are dried and then bound to the specimens. However, this method for making specimens is cumbersome to operate. The heavy objects used to press the specimens are not fixed, and sometimes the pressed specimens are not shaped
