A graphene sheet combining graphite flake structure includes a graphite nanoplatelet material and a graphene material. The graphene material is mixed in the graphite nanoplatelet material, and the content of the graphene material is between 1% and 80% of the graphite nanoplatelet material. A slurry for manufacturing the graphene sheet combining graphite flake structure and a manufacturing method for the graphene sheet combining graphite flake structure are also disclosed.

A lens fixing mechanism includes a lens base having a hollow structure and a breach structure formed on the hollow structure and a lens clamp. A ring portion of the lens clamp has an opening and a protruding structure. Two sheets extend outwardly from the opening. The protruding structure protrudes from a periphery toward a center of the ring portion. When the ring portion sleeves the hollow structure to insert the protruding structure into the breach structure and a lens module is inserted into the hollow structure, the sheets are connected to each other to pack the ring portion to contract inwardly, so as to make the protruding structure pass through the breach structure for clamping the lens module and make a portion of the periphery of the ring portion except the protruding structure to clamp a portion of a periphery of the hollow structure except the breach structure.

A surveillance device includes a shell, a sensing assembly and a transparent cover. The transparent cover is detachably disposed on the shell, to form an accommodating space together. The sensing assembly is disposed in the accommodating space. The transparent cover comprises a first light-transmitting cover, an annular light baffle and a second light-transmitting cover. The first light-transmitting cover is disposed on the shell and having a through hole. The annular light baffle disposed at the through hole has a first limiting surface and a second limiting surface. The first light-transmitting cover is pressed against the first limiting surface. The second limiting surface faces oppositely away from the accommodating space. The second light-transmitting cover is disposed on the annular light baffle and pressed against the second limiting surface. The first limiting surface and the second limiting surface prevent the second light-transmitting cover from moving toward the accommodating space.

Surveillance device

A photographing device comprises an assembling component, an image capturing component, a first annular fastener, a first stopping part and a second annular fastener. The assembling component comprises a hollow case, a protruding part, a first fastening part and a second fastening part. The hollow case has an inner surface, a first end and a second end. The protruding part is located at inner surface to form a supporting space together. The first fastening part and second fastening part are located at first end and second end, respectively. The image capturing component is located in supporting space. The first annular fastener has a third fastening part fastened to first fastening part and an annular abutting part. The first stopping part is connected to first annular fastener or first end. The second annular fastener has a fourth fastening part fastened to second fastening part and a second stopping part.
