摘要： A telescopic lamp comprising a lamp handle; a first support, having a first light-emitting member disposed thereon; a second support, extending in the same direction as the first support, slidably connected to the first support along a length direction of the first support, and having a second light-emitting member mounted thereon; wherein, the second light-emitting member and the first light-emitting member extend in the same direction and are staggered in arrangement; during a process of relative sliding of the second support and the first support, the second support has a contracted state, in which the second support is stacked on the first support. When storing the lamp, the second support is slid to the contracted state, and the second light-emitting member and the first light-emitting member are stacked in arrangement, which can shorten the overall length of the lamp, especially lamps with an elongated strip shape.

摘要： A protective device protective shell includes a detachable external lens. A lens holder is positioned on the pivot positioning member and coupled to the housing body, and the first elastic member is axially disposed along the pivot positioning member, so that the lens holder only needs to overcome the first positioning portion when rotating around the pivot positioning member. The static friction force between the first mating positioning portions and the biasing force of the first elastic member avoids generating a rotational moment to the first elastic member, thereby preventing the first elastic member from being damaged due to the rotational moment, thereby making the lens holder rotate more smoothly. The sliding is used to greatly extend the service life of the protective casing of the external lens shooting device of aspects of the invention, and the structure thereof is simple, thereby saving production cost.

摘要： An external lens for a mobile terminal includes a first lens group and a second lens group composed of cylindrical lenses arranged from an object side to an image side, the first lens group of light in the X direction The power of the second lens group in the X direction is greater than zero; the power in the Y direction of the external lens is zero. In this way, by using the unique optical characteristics of the cylindrical mirror, the horizontal field of view of the camera of the mobile terminal may be increased and the vertical field of view angle is not changed.
