The invention provides an electronic device. The electronic device comprises a front plate, a switch assembly arranged on the front plate, a fixing plate arranged at the rear side of the front plate, a magnetic frame arranged at the rear side of the fixing plate, a drive assembly arranged on the magnetic frame, and an electronic module accommodated in the magnetic frame in a sliding manner, wherein, the drive assembly is equipped with a motor electrically connected with the switch assembly, and a gear set connected with the motor; the electronic module is equipped with a plurality of saw teeth meshed with one gear in the gear set; after the switch assembly is pressed, the switch assembly drives the motor to rotate along a first direction, and then the motor drives the gear set so as to drive the electronic module to slip out of the electronic device; and after the switch assembly is pressed again, the switch assembly drives the motor to rotate along a second direction opposite to the first direction, and then the motor drives the gear set so as to drive the electronic module to slip into the electronic device via openings of the front plate and the fixing plate, thus facilitating assembly or disassembly of the electronic module.
