Temperature-controllable electric heating constant-temperature drying box

A temperature-controllable electric heating constant-temperature drying box relates to the field of drying boxes and comprises a drying box body, a drying cavity is formed in the drying box body, a driving sleeve is rotatably connected to the lower side wall of the drying cavity, and the driving sleeve extends downwards to penetrate into the drying box body to be connected with a power source. A bottom heating plate is fixedly arranged on the driving sleeve in a sleeving mode, side heating plates are fixedly arranged on the upper end face of the bottom heating plate in a bilateral symmetry mode, and telescopic rods are fixedly arranged on the lower side wall of the drying cavity. And meanwhile, the heat of the drying cavity can be effectively and fully utilized through the heat blocking block arranged on the upper side, meanwhile, the surface of the drying piece can be dried more uniformly, the temperature in the drying cavity is guaranteed, and meanwhile energy use is reduced. 一种温度可控式电热恒温干燥箱，涉及干燥箱领域，包括干燥箱体，所
