It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] Specific implementation method 1: Combination Figure 1-7 As shown, a display device for agricultural science education includes: a support plate 1, slideways 101 are respectively provided at the lower parts of both ends of the support plate 1, a crimping piece 2 is provided on the support plate 1 above the slideway 101, a support block 3 is provided in the slideway 101, an adjusting piece 4 is provided in the middle of the support block 3, and the upper part is connected to the crimping piece 2; a clamping plate 5, the two ends of the clamping plate 5 are respectively connected to the support block 3 in a sliding manner, and the end surface is connected to the adjusting piece 4 by a rotating shaft;

[0027] When in use, the chicken heart bottles are placed in the middle area of ​​the support plate 1 in turn, and then the two clamps 5 are driven to move relative to each other through the adjustment part 4 to complete the clamping operation. In the clamping process, the clamp 5 automatically adjusts the position of each chicken heart bottle by pushing the chicken heart bottles to gather towards the center, and then the support block 3 is pushed downward along the slide 101 for a certain distance by releasing the crimping part 2 to complete the clamping of the bottle mouth and realize the overall clamping and clamping operation. The operation is simple and convenient, and multiple chicken heart bottles can be fixed at one time with high fixing efficiency. Moreover, the elastic force of the crimping part 2 is relied on to press, thereby avoiding the occurrence of excessive pressure.

[0028] A preferred embodiment, combined with Figure 1 and Figure 2 As shown, the crimping part 2 includes a mounting plate 201 and a spring 202; the mounting plate 201 is welded to the upper position of the support plate 1, and a threaded handle 203 is installed in the middle of the mounting plate 201, and the lower end of the handle 203 has a rope body 204 connected to the support block 3; the spring 202 is used in pairs, wherein one end of the spring 202 is connected to the support plate 1, and the other end is connected to the support block 3; when the chicken heart bottle needs to be pressed downward, the handle 203 is rotated to release the elastic force of the spring 202, and the support block 3 is pushed downward along the slide 101, so that the clamping plate 5 is pressed and contacted with the chicken heart bottle mouth to complete the fixation, and the elastic force of the spring 202 can be used to ensure the stability of the pressing force to avoid damage to the bottle mouth caused by excessive force, and the handle 203 and the support block 3 are connected by a rope body 204, and the tightness of the rope body 204 can be judged to confirm whether the pressing is effectively achieved.

[0029] A preferred embodiment, combined with Figure 5As shown, a rotating shaft 205 is provided at the lower end of the rope body 204, and a connecting hole is provided on the support block 3. The connecting hole is connected with the rotating shaft 205 to achieve the connection and fixation between the rope body 204 and the support block 3. When the rope body 204 is excessively twisted, the rope body 204 can be adjusted by rotating the rotating shaft 205, and at the same time, the wear problem caused by the direct connection between the rope body 204 and the support block 3 is avoided.

[0030] A preferred embodiment, combined with Figure 2-4 As shown, the adjusting member 4 includes a positioning shaft 401, a swing arm 402 and an intermediate rod 403; one end of the positioning shaft 401 is welded and fixed to the support block 3, and the middle part of the positioning shaft 401 is sleeve-connected to the swing arm 402; the two ends of the swing arm 402 are respectively connected to the rotating shafts at the ends of the clamping plate 5 through the intermediate rod 403. When the chicken heart bottle needs to be clamped, it is only necessary to rotate the swing arm to drive the two clamping plates to slide relative to each other through the intermediate rod to achieve the clamping operation of the chicken heart bottle, and the restriction can be released by rotating in the opposite direction. The operation is simple and convenient.

[0031] A preferred embodiment, combined with Figure 6 As shown, an elastic layer 501 is provided on the lower surface of the splint 5. The elastic layer 501 is made of rubber material. By utilizing the elasticity of the rubber itself, it can avoid collision with the chicken heart bottle during the pressing process, and at the same time increase the friction after the two are in contact, thereby improving stability.

[0032] A preferred embodiment, combined with Figure 6 As shown, inclined surfaces 502 are provided on both sides of the clamping plate 5, which better fit the shape of the heart-shaped bottle and facilitate clamping and pressing. Specific implementation method 2

[0034] Combination Figure 3 and Figure 4 As shown, after the clamping operation is completed by rotating the swing arm 402, the positioning of the swing arm 402 itself is often achieved by relying on the friction between it and the positioning shaft 401, which is prone to loosening. For this reason, a thread can be processed at the front end of the positioning shaft 401, and a threaded connection pressure plate 404 can be provided. The pressure plate 404 is rotated to contact and press the surface of the swing arm 402, and the friction force is used to assist the positioning, which is more reliable after being fixed. Specific implementation method three

[0036] Combination Figure 7 As shown, the present technical solution can also be used in multiple groups in coordination, by adding a frame-type bracket, connecting the two ends of the support plate 1 to the bracket, such as welding or screwing, to achieve assembly, thereby forming a multi-layer display area, improving space utilization, and facilitating upper and lower layer comparative display of multiple types of seeds.
