Locking mechanism and electronic device module having the same

An electronic device module comprising:

• a rack;
• and
• at least one electronic device, each of the at least one electronic device comprising a body and a locking mechanism, the body connects to the locking mechanism, the locking mechanism detachably assemble on the rack, wherein:
• the locking mechanism comprising:
• a locking mechanism configured to detachably assemble a body to a rack, the locking mechanism comprising:
• a housing configured to connect the body, the housing comprising a first member and a second member connected to each other, the first member and the second member disposed along a first direction;
• and
• at least one linkage assembly installed on the housing, each of the at least one linkage assembly comprising a rotating member, an operating member, and a locking assembly, the operating member and the locking assembly disposed in the rotating member, the rotating member comprising a first end and a second end opposite to the first end, the first end rotatably connected to the first member and configured to clamped with the rack, the operating member rotatably connected to the second end, the locking assembly mounted on the second end, the second end defining a through hole, the locking assembly configured to extend through the through hole and clamped with the second member, thereby securing the at least one linkage assembly to the rack,
• wherein a side of the operating member facing the first member is configured to rotate in a direction away from the first member, thereby causing the at least one linkage assembly to move in the first direction away from the second member and be detached from the second member;
• the operating member is further configured to rotate and drive the rotating member rotate around the first end, thereby causing the first end to detach from the rack.
