The invention provides a positioning device. A rotation space is arranged on one side of a penetrating hole in a sleeve. A limiting ring body is arranged at the top of the outer side of the sleeve. Afirst limiting slot, two second limiting slots and a convex ring between the two second limiting slots are arranged on the outer edge of the limiting ring body. A positioning element penetrating intothe penetrating hole and an elastic element arranged on the positioning element in a sleeving mode are arranged on the bottom surface of a rod head of a rotary buckling element outside the sleeve. Therod head is positioned in an assembling space of a driving sleeve body. A long convex rod and two short convex rods corresponding to the first limiting slot and the two second limiting slots respectively are arranged in a sliding inner hole formed in the one side of the assembling space and covering the limiting ring body. During locking operation, the driving sleeve body can rotate in two directions. But during unlocking operation, the driving sleeve body can only rotate in one direction. Therefore, the purpose of easily recognizing the locking or unlocking state through different operationhand feelings is realized.

The application discloses a light sensor component and an electronic device with the same. The light sensor comprises a main board, a light-sensing device, and a cover body, wherein the light-sensingdevice is arranged on the main board and connected with the main board; N ridges are formed on the peripheral wall of the light-sensing device; a groove extending along the length direction of the ridges of n adjacent ridges, wherein n is more than 0 and not more than N-1; the cover body is covered on the light-sensing device, the inner peripheral wall of the cover body is cooperated with the peripheral wall of the light-sensing device, and a bulge cooperated with the groove is arranged at n adjacent ridges corresponding to the groove on the inner peripheral wall of the cover body, and the bulge extends along the length direction of the ridge of the cover body. According to the light-sensor component disclosed by the application, an operation of reversely installing the cover when the light-sensing device is assembled can be prevented, and good poka-yoke effect is provided. Furthermore, the connection fixation of the cover body and the light-sensing device can be realized through the cooperation of the groove and the bulge, the size of the light-sensor component can be reduced, and the occupied space in the electronic device is reduced.

The invention belongs to the technical field of mortice door locks, and in particular relates to an anti-break mortice door lock head. The anti-break mortice door lock head comprises a lock cylinder shell, a left lock head, a right lock head and a shifting piece, wherein the left lock head and the right lock head are mirror images of each other and installed on the lock cylinder shell; a lock cylinder is installed in the right lock head; the shifting piece is installed between the left lock head and the right lock head and connected with the lock cylinder; an installation groove is formed on the upper part of the lock cylinder shell; an anti-break rod is installed in the installation groove; positioning clamping grooves are formed in the bottom of the installation groove; positioning clamping blocks are arranged at the bottom of the anti-break rod and can be inserted into the positioning clamping grooves; pin tumbler holes are formed in the lock cylinder shell; inner ejector pin tumblers are installed in the pin tumbler holes through springs; and the openings of the pin tumbler holes are positioned at the bottom of the installation groove. The anti-break mortice door lock head is simple in structure, convenient to install, and capable of effectively preventing violent breaking, being fixedly locked, and preventing the broken lock head from being rotated or unlocked by the shifting piece.
