[0002] At present, the available fishing devices only have simple fishing rods. A fishing clip is arranged at the bottom of the fishing rod, and a handgrip is arranged at the top of the fishing device. By adjusting the switch above, the sample can be clamped. However, since the liquid nitrogen tank is made of 304 stainless steel and is opaque, for a depth of nearly 2 meters and in a deep low-temperature situation, the sample that has fallen can only be blindly searched by the fishing device, and it is impossible to quickly find the dropped sample.

[0003] The existing fishing devices only have simple fishing rods and fishing clips, and it is not easy to find the scattered cryogenic storage tube samples at the bottom of the liquid nitrogen tank. During the fishing process, people will be exposed to the liquid nitrogen tank opening for a longer time, and the risk of frostbite to people is greater. Moreover, during the fishing process, the opening time of the liquid nitrogen tank is long, and the liquid nitrogen volatilizes faster, increasing the cost. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve the problem that the longer exposure time at the liquid nitrogen tank opening will increase the risk of frostbite to people, the utility model provides a visual fishing device in a deep storage container.

[0025] The fixed structure 2 includes a pressing plate 201. A clamping groove 202 is formed inside the pressing plate 201, and a moving groove 203 is formed inside the pressing plate 201. Both sides of the limiting block 204 are movably connected with moving blocks 205. One end of the moving block 205 is fixedly connected with a clamping block 206. One side of the clamping block 206 is fixedly connected with a first spring 207. The surface of the handle 3 is fixedly connected with a support rod 208. One end of the support rod 208 is fixedly connected with a moving rod 209. One end of the moving rod 209 is fixedly connected with a first engaging block 210. The surface of the moving rod 209 is movably connected with a second engaging block 211. The back side of the second engaging block 211 is fixedly connected with a second spring 212, and the second spring 212 is fixed to the front side of the support rod 208.

[0026] Referring to Figure 4 , a fixing block 11 is fixedly installed at the top of the protection block 18, and a fixing plate 12 is fixedly installed at the top of the fixing block 11. The fixing plate 12 is concave in shape. Through the setting of the fixing plate 12, the flashlight case 4 can be quickly installed and replaced;

[0027] Referring to Figure 4 , the flashlight case 4 is installed on the inner wall of the fixing plate 12. The surface of the flashlight case 4 is fixedly connected with a lamp shade 16, and a light bulb 17 is fixedly connected inside the lamp shade 16. Through the setting of the light bulb 17, the device can achieve the effect of emitting light. Through the design of the lamp shade 16, the light irradiation is more concentrated;

[0028] Referring to Figure 1 , the front end of the straight rod 1 is fixedly connected with a positioning plate 5. A sliding rod 8 is fixedly connected inside the positioning plate 5. The surface of the sliding rod 8 is rotatably connected with a pressing plate 6. Through the setting of the sliding rod 8, the pressing plate 6 can open and close with the positioning plate 5;

[0029] Referring to Figure 1 , the surface of the pressing plate 6 is fixedly connected with a third spring 7. One end of the third spring 7 is fixedly connected to the surface of the straight rod 1. Through the setting of the third spring 7, when it is stretched and deformed, the pressing plate 6 closes, and when it returns to its original shape, the pressing plate 6 opens;

[0030] Referring to Figure 1 , one end of the pressing plate 6 is fixedly connected with a movable rod 9. The surface of the movable rod 9 is rotatably connected with a displacement rod 10. One end of the displacement rod 10 is movably connected with a connecting rod 19. One end of the connecting rod 19 is fixedly connected to the surface of the pressing plate 201. Through the setting of the displacement rod 10, the connection between the connecting rod 19 and the pressing plate 6 is achieved. Then, by pressing the pressing plate 201, the pressing plate 6 and the positioning plate 5 can be closed to clamp the sample.

[0031] Refer to Figure 4 , a fixing hole 13 is provided in the inner cavity of the fixing plate 12. A screw 14 is movably connected inside the fixing hole 13. One side of the surface of the screw 14 is threadedly connected with a nut 15. One side of the nut 15 is in close contact with the surface of the fixing plate 12. Through the setting of the fixing hole 13, the screw 14 can smoothly penetrate the fixing plate 12. At the same time, the settings of the screw 14 and the nut 15 can fix the position of the flashlight case 4 in the fixing plate 12, thus facilitating the installation and removal of the flashlight case 4;

[0032] Refer to Figure 2 , both sides of the inner wall of the moving groove 203 are fixedly connected with limiting blocks 204. The surface of the limiting blocks 204 is slidably connected to the surface of the moving block 205. One end of a first spring 207 is fixedly connected to the inner side of the limiting block 204. Through the setting of the limiting block 204, the position of the clamping block 206 is blocked and limited to prevent the clamping block 206 from moving out of the moving groove 203.

[0033] Working principle: When the staff needs to salvage the cryopreserved tube samples in the liquid nitrogen tank, first open the flashlight case 4 installed in the fixing plate 12. At this time, the bulb 17 will emit light. Then, insert the left end of the straight rod 1 into the tank. When the staff visually observes the sample to be salvaged in the tube body, align the positioning plate 5 with the sample. Then, hold the pressing plate 201. At this time, the pressing plate 201 drives the connecting rod 19 to move to the right. The connecting rod 19 drives the displacement rod 10 to move to the right. The displacement rod 10 makes the pressing plate 6 close towards the positioning plate 5 through the movable rod 9 to clamp the sample. After holding the pressing plate 201, at this time, the first engaging block 210 will extend into the engaging groove 202, and the clamping block 206 will move towards the outside of the moving groove 203 due to the force. The movement of the moving groove 203 drives the moving block 205 to slide inside the moving groove 203. At the same time, the movement of the moving block 205 will cause the first spring 207 to be compressed and deformed. When the first engaging block 210 passes by the clamping block 206, the clamping block 206 will drive the clamping block 206 to move inward due to the action of the first spring 207, making the first engaging block 210 unable to move outward. At this time, if the staff has taken out the sample and needs to put down the sample, just hold the pressing plate 201 again. At this time, the second engaging block 211 on the surface of the moving rod 209 will extend into the engaging groove 202 and be attached to the first engaging block 210 through the clamping block 206. Because of the second spring 212 at the bottom of the second engaging block 211, the second engaging block 211 moves outward. Through the trapezoidal design of the second engaging block 211, the second engaging block 211 and the first engaging block 210 are pulled out of the engaging groove 202, thus driving the pressing plate 201 to move to the left, driving the connecting rod 19 to move to the left. The connecting rod 19 drives the displacement rod 10 to move to the left. The displacement rod 10 makes the pressing plate 6 open through the movable rod 9.

[0034] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
