Linkage mechanism and electronic device

An electronic device, comprising:

• a first body, comprising a linkage mechanism, wherein the linkage mechanism comprises:
• a base;
• at least one first linking rod, comprising a first pivot portion and a second pivot portion, wherein each of the at least one first linking rod is pivoted to the base via the first pivot portion;
• a first linkage member, comprising a first engaged portion and a first groove extending along a first direction, wherein each of the first linking rod is pivoted in the first groove of the first linkage member via the second pivot portion so as to be adapted to be moved along the first groove;
• and
• a driving member, connected to the at least one first linking rod, and adapted to be moved between an unlocked position and a locked position;
• and
• a second body, detachably disposed at the first body, and comprising a through hole, a plurality of inner side walls surrounding the through hole, and a recessed hole recessed in one of the inner side walls, wherein the linkage mechanism of the first body is adapted to be extended into the through hole of the second body,
• when the linkage mechanism of the first body is extended into the through hole of the second body, and the driving member is located at the unlocked position, the first engaged portion of the first linking member is retracted inside the base,
• when the driving member is moved from the unlocked position to the locked position, the at least one first linking rod is driven by the driving member, so that the second pivot portion of the first linking rod is moved along the first groove, the first linking member is further driven to be moved along the second direction, so that the first engaged portion protrudes from the base and extends into the recessed hole of the second body.
