Fastener opened from single side and watch

Abstract

The invention provides a fastener opened from a single side. The fastener comprises a fastener frame, a fastener tongue pivotally jointed with the fastener frame, a relief cover movably arranged on the fastener tongue, and an elastic piece arranged between the relief cover and the fastener tongue, wherein the fastener frame is provided with a first hook block; the relief cover is provided with a second hook block corresponding to the first hook block; one end of the elastic piece pushes against the fastener tongue, while the other end of the elastic piece pushes against the relief cover, and when the fastener tongue is fastened to the fastener frame, the relief cover is pushed by the elastic piece, so that the second hook block is fastened to the first hook block; and the movement strokes of the relief cover comprises a position enabling the second hook block to be fastened to the first hook block and a position enabling the second hook block to be separated from the first hook block. The invention also provides a watch with the fastener. The relief cover is pushed by the elastic piece, so that a second component on the relief cover is fastened to a second component of the fastener frame, and therefore, the fastening of the fastener tongue and the fastener frame is realized; unfastening can be realized just by pushing the relief cover to move towards one side; and both wearing and unfastening are convenient.
