Technical Field
[0001] The utility model relates to the technical field of plant dissection tools, in particular to a wheat caryopsis dissector. Background Art
[0002] The emasculated wheat ears can be fertilized with corn pollen to achieve pseudo-fertilization of wheat embryo cells. The pseudo-fertilized embryos develop into haploid embryos, which grow in caryopsis without endosperm. Due to the low success rate of pseudo-fertilization, a large number of wheat caryopsis need to be dissected for search during the embryo rescue process.
[0003] The existing method of dissecting caryopsis is to manually fix the caryopsis one by one, and then cut it with a knife for dissection. Since the caryopsis is small, it is inconvenient to fix it and the workload is large.
[0004] Therefore, it is necessary to propose a wheat caryopsis dissector to solve the above problems. Utility Model Content

[0007] In a preferred embodiment of the present invention, two limit rods are symmetrically arranged on the fixed plate, located at the front and rear sides of the fixed beam and the movable beam respectively, and the limit rods are used to align the ends of the movable beam when the movable beam moves left and right.
[0008] In a preferred embodiment of the present invention, anti-drop holes are provided at the front and rear portions of the side of the movable beam away from the fixed beam, and the ends of the abutment members are movably connected to the anti-drop holes.
[0009] Furthermore, the resistance member includes a resistance rod and an anti-dropping ball and a handle respectively arranged at both ends of the resistance rod, an end of the resistance rod close to the handle is provided with an external thread matching the internal thread of the internal thread hole, and the anti-dropping ball is arranged in the anti-dropping hole and movably connected with the anti-dropping hole. When the resistance member is rotated forward and reversely, the resistance member moves left or right, driving the movable beam to move left or right, and then the range between the two beams can be adjusted according to the width of the caryopsis.
[0010] In a preferred embodiment of the present solution, a plurality of arc-shaped positions are arranged at intervals on one side of the fixed beam close to the movable beam.
[0011] Implementing the embodiments of the utility model has the following beneficial effects:
[0012] The wheat caryopsis dissector can adjust the distance between the movable beam and the fixed beam through the abutment piece, and can clamp about 10 caryopsis at a time. The fixed caryopsis can be lightly cut open at the upper part with a cutter and can be used to clearly check whether there is a haploid embryo under a dissecting microscope, which is not only convenient but also very efficient.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The wheat caryopsis dissector comprises a fixer for fixing the caryopsis and a cutter for dissecting the caryopsis.
[0020] See also Figure 1-2 , Figure 1 It is a schematic diagram of the top view of the structure of the fixer of the wheat caryopsis dissector; Figure 2 The figure is a front view of the fixture; the fixture includes a fixing plate 1, on which a fixing beam 2 and a positioning plate 3 are fixedly arranged on the left and right sides respectively, a movable beam 4 is arranged between the fixing beam 2 and the positioning plate 3, and anti-drop holes 6 are provided at the front and rear parts of the movable beam 4 on the side away from the fixing beam 2, and a plurality of arc positions 15 are provided at intervals on the side of the fixing beam 2 close to the movable beam 4 for positioning and placing caryopsis, and generally about 10 arc positions 15 are provided. Through internal threaded holes 5 are provided transversely on the front and rear parts of the positioning plate 3. Generally speaking, the fixing beam 2 and the movable beam 4 are selected to be about 3 mm high.
