Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plant tissue culture propagation tools, in particular to a dual-purpose tissue culture knife. Background Art
[0002] The in vitro organs used for plant tissue culture usually need to be cut into small pieces for sterile culture. The size of the cuts needs to be uniform and the cuts need to be neat to ensure normal growth in the future. Tissue culture knives are a type of cutting experimental equipment commonly used in tissue culture experiments. However, existing tissue culture knives are usually single-edged tissue culture knives. The knife position needs to be re-fixed after each cut, resulting in the size of the explants being inconsistent. If they are too small, the workload of subsequent subculture experiments will increase. If they are too large, it will be detrimental to the induction and differentiation of callus tissue, which will affect the experimental results to a certain extent. At the same time, it is inconvenient for existing tissue culture knives to cut soft and small leaves, and it is difficult to accurately control the size of the excised leaves. Not only is the slicing efficiency slow and the specifications are inconsistent, but it is also not conducive to plant tissue culture, affecting the efficiency of the experiment.

[0010] A threaded connector is provided in the fixing port, and the threaded connector includes a connecting stud and a connecting nut. The connecting stud passes through the sliding groove and the fixing port from the front of the handle base and is threadedly engaged with the connecting nut on the back of the handle base. The sliding engagement of the clamp head and the handle base is achieved through the engagement of the threaded connector and the fixing port. By pushing the threaded connector, the clamp head and the cutter connected to the clamp head can be extended out of or retracted into the handle base.
[0011] Furthermore, the clamping angle between the axis of the connecting tube and the horizontal plane is 45°, and this angle setting facilitates the pressing and shearing of the tail knife device.
[0012] Furthermore, the cross-section of the tail ring cutter is circular or square.
[0013] Furthermore, a scale is provided on the front or back side of the head end of the clamp along its length direction. The setting of the scale can measure the size of the anatomical object and increase the accuracy of plant tissue culture.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the dual-purpose tissue culture knife in the utility model presses the plant leaves through the tail ring knife in the tail knife device to cut out small leaves of the same specifications, which is convenient for plant tissue culture, solves the problem of soft and collapsed leaves or leaves that are too small to be easy to operate, and improves tissue culture efficiency.
