[0021] (III) Beneficial Effects

[0022] The present invention provides a fixation device for animal dissection experiments, which has the following advantages:

[0023] (1) This utility model incorporates a fourth slot, a thermostatic component, a water pump, and a spiral pipe within the lower housing. The fourth slot contains a thermostatic solution used to maintain a stable internal temperature within the lower housing. A temperature sensor is also installed within the lower housing. Since the fixative requires a suitable temperature for storage, the temperature sensor automatically detects the internal temperature. When the internal temperature is too high, the cooling component in the thermostatic component cools the solution, and the water pump drives the cooled water into the spiral pipe, achieving a cooling cycle. When the internal temperature is too low, the heating component heats the solution, and the water pump drives the heated water into the spiral pipe, achieving a heating cycle. This design ensures a stable internal temperature within the lower housing, effectively extending the storage time and effectiveness of the fixative, and improving the convenience of experiments.

This design ensures that the sprue plate is locked immediately after installation, preventing displacement during experimental use. Attached Figure Description

[0043] Furthermore, there are two lifting mechanisms 4, which are respectively arranged adjacent to each other next to the two second slots 12.

[0044] exist Figures 1 to 5In an optional embodiment, a sluice plate 5 is disposed at the bottom end of the upper housing 1. A third slot 51 is provided on both sides of the sluice plate 5.

When the internal temperature is too high, the cooling component 35 cools, and the water pump 33 drives the cooled water to enter the spiral pipe 34 to realize the cooling cycle. When the internal temperature is too low, the heating component 36 heats, and the water pump 33 drives the heated water to enter the spiral pipe 34 to realize the heating cycle.

The first sliding tooth block 52 of the sprue plate 5 can be inserted into the locking assembly 6 and mesh with the gear 61, thereby driving the gear 61 to rotate. The gear 61 meshes with the second sliding tooth block 62, and the rotating gear 61 drives the second sliding tooth block 62 to extend, completing the locking. This design ensures that the sprue plate 5 is locked after installation, preventing displacement of the sprue plate 5 during experimental use.

[0056] The lower housing 3 is equipped with a fourth slot 54, a thermostatic component 32, a water pump 33, and a spiral pipe 34. The fourth slot 54 contains a thermostatic solution used to maintain a stable internal temperature within the lower housing 3. A temperature sensor is also installed in the lower housing 3. Since the fixative requires a suitable temperature for storage, the temperature sensor automatically detects the internal temperature. When the internal temperature is too high, the cooling component 35 in the thermostatic component 32 cools the solution, and the water pump 33 draws the cooled water into the spiral pipe 34, achieving a cooling cycle. When the internal temperature is too low, the heating component 36 heats the solution, and the water pump 33 draws the heated water into the spiral pipe 34, achieving a heating cycle. This design ensures a stable internal temperature within the lower housing 3, effectively extending the storage time and effectiveness of the fixative, and improving experimental convenience.
