Abstract: A rotating buffer station for a chip mainly comprises an upper cover plate, a rotatable plate, a movable jaw member and a lower base. The upper cover plate is arranged on the lower base and formed with a guide slot. The rotatable plate is located between the lower base and the upper cover plate and formed with a cam slot. The rotatable plate is pivotally coupled to the lower base. The movable jaw member is slidably engaged with the cam slot and the guide slot. When the rotatable plate is rotated, the cam slot forces the movable jaw member to move radially along the guide slot so as to form a chip socket. Accordingly, with rotation of the rotatable plate, the cam slot forces the movable jaw member to move radially along the guide slot so that the chip socket can be resized to hold various differently-sized chips.
