Abstract
A locking device includes a housing, a first linking member, a second linking member, a push-pull member, and a stopper. The push-pull member defines a first sliding groove. A first end portion of the first linking member is slidably received in the first sliding groove, and a second end portion of the first linking member is rotationally fixed on the housing. The housing defines a second sliding groove. The stopper is slidably received in the second sliding groove. A second end portion of the second linking member is rotationally mounted on the first linking member. The first end portion of the first linking member is driven by the push-pull member to move along the first sliding groove, which drives the second linking member to rotate, which drives the stopper to move along the second sliding groove.
