After moving to a suitable position, the user holds the handle 123 to stand up the storage box 104, so that the fixing block 120 is against the ground, and the spring 119 begins to compress to prevent the side of the lower box 110 away from the roller 106 from directly contacting the ground and causing damage. The two fixing blocks 120 are connected by the connecting rod 121 to make it more stable when it is against the ground. The outer waterproof layer 115 covers the surface of the upper box body 112 and the lower box body 110, so that the upper box body 112 and the lower box body 110 can be waterproofed, so as to prevent the storage box 104 from being soaked by rainwater in rainy days, causing the camera body 101 to be damaged by water, and the corners of the storage box 104 are wrapped by the side corner guards 116, thereby solving the problem that the existing single-photon camera based on the double-layer MCP image intensifier cannot protect the camera when carried during travel, resulting in the camera being easily damaged after colliding with foreign objects.
