This design can prevent the observer from continuously holding the rotating rod 40 when observing the fish specimen, thereby effectively freeing both hands, providing convenience for the observer to record data of the fish specimen.

[0029] The implementation principle of the fish specimen box in the embodiment of the present application is as follows: the staff connects the fish specimen to the bottom end of the suspension rope 18, so that the fish specimen contacts the bottom end of the socket plate 20, and then pulls the pull rod 68 to move the two clamping plates 42 away from each other, and then starts the motor to rotate the winding wheel, so that the winding wheel can wind the suspension rope 18, so that the socket plate 20 moves between the two pull rods 68, and then loosens the pull rod 68 to clamp the two clamping plates 42 to fix the socket plate 20, and then according to the length of the fish specimen, the fish specimen is moved. The specimen is suspended above the width measuring frame 15. When the fish specimen is long, the motor is started to reel in the suspension rope 18 and move the sleeve plate 20 upward, which will cause the lifting cylinder 23 to slide upward inside the fixed cylinder 21, thereby shortening the overall length of the fixed cylinder 21 and the lifting cylinder 23. Since the suspension rope 18 is located inside the fixed cylinder 21 and the lifting cylinder 23, and the sleeve plate 20 is fixed by the clamping plate 42, the suspension rope 18 can be prevented from sliding in the specimen liquid, thereby effectively improving the suspension stability of the fish specimen. When the observer stands on one side of the box body 1 to observe the fish specimen, he presses the rotating plate 47 downward, so that the rotating plate 47 pushes the rectangular tube 49 downward, and the rotating plate 47 drives the notch 50 to slide on the outside of the mounting rod 51, so that the magnetic piece 19 is adsorbed and connected with the magnetic piece 27, and at the same time, the spring 41 is stretched and generates elastic force, and the rectangular tube 49 drives one of the tooth plates 60 to move downward, and through the meshing connection relationship between the tooth plate 60 and the gear 3 57, the other tooth plate 60 is moved upward, and then the lifting plate 58 is moved upward, and the lifting plate 58 drives the push ring 59 to move upward, so that the push ring 59 drives the friction ring 46 thereon to be in close contact with the friction ring 46 at the bottom end of the rotating disk 44. Therefore, the adsorption force between the magnetic piece 19 and the magnetic piece 27 is greater than the elastic force of the spring 41, which can maintain the close contact stability of the two friction rings 46, effectively realize the fixation of the rotating disk 44, and then realize the locking of the rotating rod 40, which can avoid the rotating rod 40 from rotating in the process of twisting the rotating cylinder 11; Then the staff rotates the rotating plate 47, so that the rotating plate 47 drives the rotating cylinder 11 to rotate, and the rotating cylinder 11 drives the rotating ring 8 to rotate through the connecting plate 10, and the rotating ring 8 drives the supporting ring 9 to slide on the top of the box body 1. Through the locking connection relationship between the locking rod 26 and the plug hole 28, the rotating ring 8 can drive the mounting cylinder 16 to rotate synchronously during the rotation process, thereby making the four fish specimens move around the rotating cylinder 11 in the specimen liquid, effectively changing the position of the fish specimens, and facilitating the observer to select the fish specimens to be observed. At the same time, the fish specimens of this design can prevent the rotating rod 40 from rotating during the movement of the specimen liquid, thereby improving the connection stability between the locking rod 26 and the plug hole 28; Because the fish specimen under observation has an obstructed surface, when observing it comprehensively, the rotating plate 47 is pulled upward to disconnect the magnetic sheet 19 from the magnetic sheet 27, and then, under the elastic force of the spring 41, the lifting plate 58 drives the push ring 59 to move downward, so that the two friction rings 46 are disconnected, and the locking of the rotating rod 40 is disconnected; Then, the electric push rod 52 is started, and the electric push rod 52 drives the conical cover 53 to move downward, so that the conical cover 53 drives the slideway 56 to slide outside the installation shaft 55. At the same time, the conical cover 53 drives the push seat 54 to move downward, and the push seat 54 squeezes the squeezing block 62, so that the rectangular rod 61 slides on the rotating cylinder 11, so that the installation seat 63 drives the latching tooth 65 to approach the rotating disk 44, and then the latching tooth 65 is inserted into the inside of the latching groove 45, so as to realize the one-way locking of the rotating disk 44. Then the observer twists the rotating rod 40, which drives the rotating disk 44 and the gear 2 43 to rotate synchronously, and the rotating disk 44 realizes the synchronous rotation of multiple slots 45. Because the latch tooth 65 is connected to the mounting seat 63 by the spring 2 67, the latch tooth 65 will be deflected during the rotation of the slot 45, which will cause the latch tooth 65 to be repeatedly inserted into different slots 45. At the same time, the rotating rod 40 will drive one of the sprockets to rotate, and through the connection relationship of the chain, the other sprocket will rotate to realize the rotation of the rotating shaft 39. The rotating shaft 39 will twist the two connecting ropes 36, and the two connecting ropes 36 will pull the slider 33 to slide upward inside the connecting groove 31, and will compress the spring 3 37, so that the locking rod 26 moves up and disengages from the socket 28, effectively disconnecting the locking connection between the mounting cylinder 16 and the rotating ring 8. At the same time, the upward movement of the slider 33 will cause the sliding rod 34 to move in the slot The gear 1 32 slides inside, so that the gear 1 35 slides upward on the outside of the installation cylinder 16, and then the gear 1 35 is meshed with the gear 2 43. By continuing to twist the rotating rod 40, the gear 2 43 drives the gear 1 35 to rotate. The gear 1 35 realizes the rotation of the installation cylinder 16 through the sliding rod 34. The installation cylinder 16 drives the fixing cylinder 21, the stabilizing cylinder 22, the lifting cylinder 23 and the socket plate 20 to rotate synchronously, and the suspension rope 18 drives the fish specimen to adjust the angle, so that the blocked surface of the fish specimen is facing the observer, so that the observer can observe the fish specimen comprehensively. Then the staff loosens the rotating rod 40. Due to the engagement of the latching teeth 65 with the latching groove 45, the rotating disk 44 can be locked, which effectively prevents the rotating disk 44 from rotating in the opposite direction. Therefore, the observer's hands can be freed, so that the observer can observe and record the fish specimen conveniently. When the observation of the fish specimen is completed, the electric push rod 52 is started to drive the conical cover 53 to move upward, which will cause the mounting seat 63 to drive the latch tooth 65 to move horizontally, thereby disconnecting the latch tooth 65 from the locking slot 45. Under the reverse action of the spring three 37, the slider 33 will drive the locking rod 26 to move downward, so that the locking rod 26 is inserted into the socket 28. At the same time, the slider 33 will drive the gear 1 35 to move downward through the sliding rod 34, disconnecting the meshing connection between the gear 1 35 and the gear 2 43, thereby realizing the re-locking of the mounting tube 16 and the rotating ring 8 and the resetting of the gear 1 35, and providing convenience for the next observer to observe the fish specimen.
