The connecting cover plate 8 is screwed and tightened with the inside of the placement port 101 through the threaded protrusion 82, and the sealing ring 81 is tightly fitted on the interface between the connecting cover plate 8 and the placement port 101, so that the main box 1 is in a light-proof and closed space. The weak energy infrared light source 23 irradiates the main box 1 with infrared light, and then the operator puts his hands into the gloves in the clamping ring 4 to operate the substance. The operation process can be recorded by the infrared camera 24 at close range of the experimental process. When opening the main box 1, the bottom block 721 is squeezed inward into the groove 720, and the shading plate 21 can be lifted upward by the elasticity of the reset spring 73 to complete the opening of the main box 1.
