[0009] By adopting the above technical solution and through the design of the slot, it is convenient to install the baffle on the upper part of the inner wall of the incubation tank. Through the design of the mounting piece, the stability of the baffle on the inner wall of the incubation tank can be improved, and it is also convenient to install and disassemble the baffle.

[0010] Specifically, the bottom ends of the mounting members are respectively located in the clamping slot and the limiting slot, and a pull block is vertically inserted in the center of the top end of the mounting member.

[0011] Specifically, the plug-in is a rectangular frame structure, and the plug-in is located in a slot.

[0012] Specifically, the installation slots, the installation pieces and the limiting slots are each provided with four groups.

[0013] Specifically, a protective strip with a rectangular frame structure is fixedly glued to the inner wall of the opening.

[0014] Specifically, the blocking member is located above the incubator box, and the blocking member is sleeved on the incubator box.

[0015] Beneficial effects of the utility model:

[0016] (1) The leech hatching device described in the utility model is convenient for installing the blocking member on the upper part of the inner wall of the hatching tank through the design of the slot. The design of the mounting member can improve the stability of the blocking member on the inner wall of the hatching tank, and also facilitate the installation and removal of the blocking member.

[0017] (2) In the leech hatching device described in the utility model, when the leech crawls along the inner wall of the hatching pool to the baffle, when the leech crawls along the curved surface to the highest point, due to the effect of gravity, the leech will fall from the baffle to the bottom of the hatching pool, thereby preventing the leech from crawling out of the hatching pool along the inner wall of the hatching pool.
