[0026] A drain port 6 is provided on the left side of the fish measuring tank 5, and scale lines 7 are engraved on the inner bottom wall of the drain port 6. By using the scale lines 7, the length of the fish body can be measured.

[0027] The N-shaped frame 10 is provided with a lifting and lowering adjustment mechanism 8 inside. The lifting and lowering adjustment mechanism 8 includes a threaded rod 802 and a lifting plate 803. The outer surface of the threaded rod 802 is threadedly connected to the inner wall of the N-shaped frame 10. The bottom end of the threaded rod 802 is rotatably connected to the upper surface of the lifting plate 803. The upper surface of the threaded rod 802 is fixedly connected with a turntable 801. By using the turntable 801, the threaded rod 802 can be easily rotated to drive the lifting plate 803 to be lifted and lowered. Two guide columns 804 are fixedly connected to the upper surface of the lifting plate 803. The outer surfaces of the two guide columns 804 are slidably connected to the inner wall of the N-shaped frame 10. By using the guide columns 804, the lifting and lowering of the lifting plate 803 can be guided.

[0028] A clamping mechanism 9 is arranged below the lifting and adjusting mechanism 8, and the clamping mechanism 9 includes an arc-shaped pressure plate 901 and a first spring 903. The arc-shaped pressure plate 901 is an arc-shaped surface, which is convenient for fitting the fish body.
