Abstract
The invention discloses a self-locking zipper head having a replaceable pulling piece, wherein a cap thereof extends toward a zipper head body and is provided with a lug; a left lug, a right lug, a left lateral ear and a right lateral ear are protruded from an end face of the zipper head body; a tubular shaft is inserted in the left lug, the right lug, the left lateral ear and the right lateral ear, thereby fixing the cap on the zipper head body, and allowing the cap to be assembly more conveniently and more precisely with a lower cost. The cap of the zipper head is further provided with a long slot; a pulling piece is arranged inside an elastic switch; and a horse-shaped hook is lifted up along the long slot, thereby opening the elastic switch. Not only the problem that the pulling piece is uneasy to install and detach due to the fact that the horse-shaped hook is not flexible after the zipper head is plated or painted is solved, but also the unlocking through a position piece in the absence of the pulling piece is achieved. The appearance of the zipper head can be further improved by assembling the pulling piece on the zipper head.
