This utility model proposes a camera lens hood, comprising: a lens hood housing with a filter mechanism for producing a filter effect; two magnetic magnets fixedly installed on the rear side of the lens hood housing, allowing the lens hood housing to be connected to a pocket camera via the magnetic magnets; and a light-shielding plate located on the front side of the lens hood housing. This lens hood is compact and convenient. The magnetic magnets facilitate the mounting and fixing of the lens hood housing onto the lens of a pocket camera. Simultaneously, the light-shielding plate prevents ambient light from entering the lens, making it easily compatible with pocket cameras. This allows professional photography accessories to reach the consumer market, enabling ordinary users to achieve near-professional light control capabilities at low cost, lowering the creative threshold, and effectively improving the shooting effect and playability of pocket cameras.

The application discloses a positioning jig and a positioning device, and belongs to the technical field of product assembly. The positioning jig comprises a base, a sliding assembly arranged on the base and sliding along an X direction, two special-shaped linkage assemblies, two special-shaped linkage assemblies are fixedly connected to the sliding assembly respectively, and the special-shaped linkage assembly has a pushing and abutting inclined surface. The positioning assembly comprises a positioning carrier arranged on the base, two first limiting blocks arranged oppositely along a Y direction, and two first reset members corresponding to the two first limiting blocks one by one. The positioning carrier has a positioning groove, the two first limiting blocks are arranged one by one corresponding to the two special-shaped linkage assemblies, the special-shaped linkage assembly can push the first limiting block corresponding to the special-shaped linkage assembly to move along the Y direction through the pushing and abutting inclined surface, one end of the first reset member is connected to the base, and the other end is limited to the first limiting block corresponding to the first reset member. The first limiting block is used for positioning a product along a Z direction. The application can use a smaller power source and has a lower cost.
