The detachable module is detachably installed on the case module and slidable relative to the case module, and an electrical connector of the detachable module is mated with a mating electrical connector of the circuit board when the detachable module is installed on the case module and slides to an engaging position. The lever mechanism includes a lever component partially located between the case module and the detachable module, and an abutting component fixed on the case module. When the lever component is operated to pivot relative to the detachable module, the lever component cooperates with the abutting component in a contacting manner to drive the detachable module to slide, so as to disengage the electrical connector of the detachable module from the mating electrical connector of the circuit board. ## Claims ### Claim 1 An electronic device with capability of lever ejection comprising: a case module;
