[0045] The blocking mechanism comprises two baffle plates 34 and a telescopic assembly, the two baffle plates 34 are symmetrically arranged on the two sides of the fish inlet 18, and the telescopic assembly is located above the two baffle plates 34;

[0046] By arranging the baffle plates 34, when the telescopic assembly works, the two baffle plates 34 can be driven to move close to each other, so that after the large-mouth bass is caught, the two baffle plates 34 move close to each other and block the fish inlet 18, so that the large-mouth bass cannot swim out from the fish inlet 18.

[0047] As shown in Figures 1-9 The mesh of the plurality of grading nets 19 is gradually reduced, specifically, the mesh of the grading net 19 close to the fish inlet 18 is larger, and the mesh of the grading net 19 far from the fish inlet 18 is smaller. When the large-mouth bass is caught, the large-mouth bass first enters the inside of the fishing box composed of the plurality of metal nets 14 through the fish inlet 18, then the fish inlet 18 is blocked by the blocking mechanism, the plurality of grading nets 19 are driven to move by the driving assembly, the plurality of grading nets 19 move towards the fish inlet 18, the swimming space of the large-mouth bass is reduced, the smaller large-mouth bass can pass through the grading net 19 with a suitable mesh, and the quick separation of fish bodies of different specifications is realized.
