The utility model discloses an SIM card tray detection device which comprises a
workbench, two supporting plates are fixedly connected to the top of the
workbench, two rotating rollers are rotationally connected between the two supporting plates, a conveying belt is arranged on the outer sides of the two rotating rollers, and a plurality of fixing seats are fixedly connected to the outer side of the conveying belt at equal intervals. The beneficial effects of the utility model are that: it is novel in structure, simple to operate, easy to master, not only compact in structure, but also stronger in practicality, and more convenient to use. Compared with a traditional device, by arranging the fixing base, the rotating shaft, the
electromagnet, the
magnet, the connecting rod, the clamping base, a first spring, a
touch switch, a gear ring, a touch rod and a rack, the
electromagnet can be controlled to be powered on by triggering the
touch switch after the fixing base moves to the clamping position, then the
touch switch generates repulsive force on the
magnet, and the clamping effect is achieved. In this way, the first spring is compressed and the clamping seat is driven to clamp the SIM card support.
