Portable electronic device and the electronic module fixing structure

A portable electronic device and an electronic module fixing structure, the portable electronic device includes an electronic module and an electronic module fixing structure. The electronic module fixing structure comprises a body, a sliding member, a member and an elastic member. A body having a rail which has a positioning portion. The sliding member slidably disposed on the main body. When the electronic module is mounted on the body, the slide member is located at a first position. The lever rotatably connected to the slider, a end of the rod member is adapted to move along the track. When the end of the positioning portion, the positioning portion end the slider interference in a first position. An elastic member connected between the body and the sliding member. When the electronic module is forced to push the slide member, the lever member moves away from the end to drive the slide member rotates relative to the positioning portion, and the sliding member slides to a second position away from the electronic module to the body by the elastic force of the elastic member. The electronic module fixing structure according to the present invention enables disassembly of the electronic module is simple.
