Abstract: A quick assembly armrest connecting device includes a connecting head and a receiving seat. The connecting head includes a body extending along a first axis. The receiving seat includes a groove extending along a second axis. The armrest connecting device is movable between an assembled position and a separated position in which the connecting head is separated from the receiving seat. When the armrest connecting device moves from the separated position towards the assembled position, the first axis is parallel to the second axis, and the connecting head moves rectilinearly along the second axis towards the receiving seat and inserts the body into the groove. After the connecting head abuts the bottom side of the groove, the connecting head moves rectilinearly in a radial direction of the second axis relative to the receiving seat, moving the armrest connecting device to the assembled position.
