A universal box lid lifter has an upper mounting plate, an upper connection piece, a pivoting arm, a spring housing, a spring assembly, a lower connection piece and a lower mounting plate. The upper connection piece has two ends oriented in two directions and is pivotally mounted between the upper mounting plate, with the pivoting arm respectively pivotable in two directions. The spring assembly is mounted in the spring housing and abuts against the pivoting arm and alternately positions the pivoting arm. The lower connection piece has two ends oriented in two directions and is pivotally mounted between the lower mounting plate, with the spring housing respectively pivotable in two directions. Given the bidirectionally pivotable mechanism at both ends of the universal box lid lifter, the universal box lid lifters of a single type can be flexibly mounted to a box as requested to lift the lid of the box.
