The connecting column 1104 is fixedly connected to the front side of the connecting block 1101. The connecting column 1104 cooperates with the adjusting mechanism 12.

[0024] With the above scheme: By setting the positioning mechanism 11, the placement box 7 can be fixed through the fixing block 9, so as to fix the placement box 7 in the placement groove 6 inside the culture rack 3 and prevent it from moving.

[0025] Reference Figure 4 As shown in the figure and reference, the adjusting mechanism 12 includes a pulling rod 1201, a sliding block 1202, a base 1203, and a swinging rod 1204. The pulling rod 1201 is fixedly connected to the front side of the sliding block 1202. The front side of the pulling rod 1201 penetrates and extends out of the surface of the fixing block 9. The base 1203 is fixedly connected to the left side of the inner wall of the cavity 10. The swinging rod 1204 is rotatably connected to the front side of the base 1203 through a rotating shaft. The rear side of the pulling rod 1201 is in contact with the surface of the swinging rod 1204. The side of the swinging rod 1204 close to the connecting column 1104 is sleeved on the surface of the connecting column 1104.

[0026] With the above scheme: By setting the adjusting mechanism 12, the fixation of the fixing block 9 on the placement box 7 can be released, and then the placement box 7 can be pulled out to observe the situation of the seeds.

[0027] Reference Figure 4 As shown in the figure and reference, a transmission hole 13 is opened on the surface of the swinging rod 1204. The inner wall of the transmission hole 13 is in contact with the surface of the connecting column 1104.

[0028] Adopting the above solution: By setting the transmission hole 13, the swing rod 1204 can be connected to the connecting column 1104, and then the movement of the swing rod 1204 can drive the connecting column 1104 to move.

[0029] Reference Figure 4 , at the top of the inner wall of the cavity 10, a guide rail 14 is fixedly connected. The guide rail 14 penetrates and extends out of the surface of the sliding block 1202. At the bottom of the guide rail 14, a base block 15 is fixedly connected. At the top of the base block 15, a compression spring 16 is fixedly connected, and the other end of the compression spring 16 is fixedly connected to the bottom of the sliding block 1202.

[0030] Adopting the above solution: By setting the guide rail 14, the base block 15 and the compression spring 16, the movement of the sliding block 1202 can be restricted by the guide rail 14, and then the sliding block 1202 can be supported by the compression spring 16.

[0031] Reference Figure 4 , on the right side of the inner wall of the cavity 10, a guide rod 17 is fixedly connected. The other end of the guide rod 17 penetrates and extends out of the surface of the connecting block 1101.

[0032] Adopting the above solution: By setting the guide rod 17, the movement of the connecting block 1101 can be restricted to prevent the connecting block 1101 from shifting during movement.

[0034] Adopting the above solution: By setting the magnetic block 18, the magnetic block 18 can adsorb to the connecting block 1101, and then prevent the connecting block 1101 from moving after adsorption.

[0035] The working principle of the present utility model:

[0036] In use, pull the pull rod 1201 downward. When the pull rod 1201 moves, it drives the sliding block 1202 to move downward. When the pull rod 1201 moves, its rear end contacts the surface of the swing rod 1204 and presses it, so that the swing rod 1204 rotates through the rotating shaft. When the swing rod 1204 rotates, it presses the surface of the connecting column 1104 through the inner wall of the transmission hole 13, thereby driving the connecting column 1104 to move away from the culture rack 3. When the connecting column 1104 moves, it drives the connecting block 1101 to move away from the culture rack 3. When the connecting block 1101 moves, it drives the insertion rod 1102 away from the inside of the insertion hole 8. When the connecting block 1101 moves, it stretches the tension spring 1103. Then, when the connecting block 1101 adsorbs to the magnet block 18, the other fixing block 9 can be operated, and then the user can take out the placement box 7.

[0037] In summary, for this seed vigor stress detection device, by the combined use of the detection box 1, detection chamber 2, culture rack 3, controller 4, temperature regulator 5, placement groove 6, placement box 7, insertion hole 8, fixing block 9, cavity 10, positioning mechanism 11, connecting block 1101, insertion rod 1102, tension spring 1103, connecting column 1104, adjustment mechanism 12, pull rod 1201, sliding block 1202, base 1203, swing rod 1204, transmission hole 13, guide rail 14, base block 15, compression spring 16, guide rod 17 and magnet block 18, it solves the problem that when adjusting environmental conditions such as temperature or humidity in the detection box, the culture rack moves or tilts due to changes in the external environment, thus affecting the accuracy of the detection results.
