Tray special for temperature-sensitive gel injector

The tray comprises a top cover, a low-temperature layer and a base plate, the low-temperature layer is detachably connected between the top cover and the base plate, the low-temperature layer comprises a low-temperature plate and a connecting shell connected to the edge of the low-temperature plate by a circle, the low-temperature plate is provided with a plurality of containing grooves, a heat preservation cavity is formed in the low-temperature plate, and the containing grooves are communicated with the heat preservation cavity. And an asbestos thermal insulation material is arranged in the thermal insulation cavity. The heat preservation cavity is a closed cavity. The low-temperature layer is detachably connected with the top cover and the base plate, the low-temperature layer and the base plate can be taken out and then placed into a refrigerator to be frozen, the temperature of the low-temperature layer and the base plate is reduced, and therefore a good heat preservation effect can be achieved on the ge
