Abstract
Description
Technical Field
[0001] This utility model relates to a device for fixing pine wood nematode samples. Background Technology
[0002] The commonly used plant nematode isolation technique in the laboratory involves the funnel method. The sample to be isolated (small pieces of wood packaging or logs) is placed in a funnel containing an appropriate amount of water, left to stand for 24 hours, and then the stopcock is opened. The nematode fluid is collected in a petri dish for microscopic examination. The principle is to immerse the plant tissue suspected of nematode in water, utilizing the nematodes' hydrotaxis and their own weight to separate them. However, in practice, because the host of pine wood nematodes is pine wood, which has a lower density than water, the nematodes often float on the surface when immersed in water for analysis, resulting in a small contact area with the water and affecting the separation effect.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] Please see Figure 1 Combination Figure 2 As shown, the embodiments of this utility model include:
[0016] A pine wood nematode sample fixing device includes a telescopic net frame and a fixing frame. The telescopic net frame is used to press the top of the pine wood to prevent it from floating on the water surface, and the fixing frame is fixed to the side wall of the container to fix the telescopic net frame below the water surface to press down the pine wood.
[0017] The telescopic mesh frame includes a first positioning main rod 1, a second positioning main rod 2, multiple positioning support rods 3, and a first positioning shaft 4.
[0018] The first positioning main rod 1 and the second positioning main rod 2 are arranged in parallel, and multiple positioning support rods 3 are distributed in a mesh structure. The first positioning main rod 1 and the positioning support rod 3, the positioning support rod 3 and the positioning support rod 3, and the positioning support rod 3 and the second positioning main rod 2 are all hinged through the first positioning shaft 4. The expansion and contraction of the telescopic mesh frame is achieved by moving the first positioning main rod 1 and the second positioning main rod 2 closer or further apart, so as to meet the pressing of containers of different specifications.
[0019] The upper surface of the first positioning main rod 1 is also provided with a plurality of positioning adjustment holes 5 at equal intervals, which are used to adjust the positioning insertion when the unfolded surface of the telescopic mesh frame is large.
[0020] A positioning adjustment rod 6 is arranged parallel to the upper surface of the second positioning main rod 2.
[0021] One end of the positioning adjustment rod 6 is hinged to a second positioning shaft 7, which is vertically fixed to the second positioning main rod 2, so that the positioning adjustment rod 6 can rotate axially around the second positioning shaft 7. The other end of the positioning adjustment rod 6 has a longitudinally distributed spring bolt 8 vertically arranged on its upper surface. The lower end of the spring bolt 8 passes through the positioning adjustment rod 6 and is inserted into the positioning adjustment hole 5. Under the action of the spring, the spring bolt 8 is elastically inserted into the positioning adjustment hole 5.
[0022] The fixing frame includes a support rod 9 and a buckle 10. The support rod 9 is vertically fixed to the middle of the side of the second positioning main rod 2 to provide longitudinal positioning height.
[0023] The buckle 10 is fixed to the outer end of the top of the support rod 9. The buckle 10 has an n-shaped structure and the opening is set downward. The buckle 10 is elastically fastened to the edge of the container to ensure the stability of the telescopic mesh frame.
