Portable multifunctional plant leaf hole puncher

Abstract

The invention discloses a portable multifunctional plant leaf hole puncher. The portable multifunctional plant leaf hole puncher is characterized in that six tool bits of different apertures and shapes are uniformly fixed to a tool bit turntable; a locking hole is corresponding formed under each tool bit; a locking stick is fixed to a pliers body through a screw behind the tool bit turntable; a bump at the front end of the locking stick is clamped into one of the locking holes to realize the fixing of the tool bit turntable and the tool bits. A corresponding tool bit gasket is selected from atool bit gasket accommodating groove in a hollow handle after the tool bits are fixed, and is clamped into a tool bit gasket groove to be fixed, and a centrifugal tube tray is fixed to the pliers bodythrough a sliding chute after a centrifugal tube is inserted into the centrifugal tube tray. A leaf is placed on the tool bit gasket horizontally, the hollow handle is connected with a spring, and ahinged shaft is connected with the locking stick, the tool bit gasket and the hollow handle. The portable multifunctional plant leaf hole puncher is simple in structure, and is convenient to use. Thehole punching sampling strength on leaves can be lowered effectively, the working efficiency is improved, real-time field sampling is realized, and the representativeness of an obtained sample and theaccuracy of an experimental research result are ensured more effectively.

Description

technical field [0001] The invention belongs to the technical field of plant leaf punchers, and more specifically relates to a portable multifunctional plant leaf puncher, which is especially suitable for different plants and different environments, and is an efficient plant leaf puncher integrating leaf punching and automatic sample collection. Sampling tool. Background technique [0002] Plant leaf sampling is of great biological significance in studying the anatomical and physiological characteristics of leaves. The current leaf sampling is mainly by picking the whole leaf of the plant in the field, putting it into a ziplock bag, putting it into a liquid nitrogen tank, and bringing it back to the laboratory. In order to ensure the representativeness of sampling, at least 5-10 leaves should be collected for each treatment of crops with relatively large leaves, and 20-30 leaves should be collected for each treatment of crops with small leaves, and field experiments often h...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the technical defects of existing plant leaf punchers, and to provide a portable multifunctional plant leaf puncher with simple structure and convenient use, which solves the cumbersome operation, time-consuming and labor-intensive operation of punching punchers. , The operation is limited by the site, the size of the clamp-type puncher head is fixed, and the collection effect of the punching blade is poor, which can effectively reduce the labor intensity of blade punching and sampling, improve work efficiency, and realize real-time field sampling. More effectively guarantee the representativeness of the samples taken and the accuracy of the experimental research results
