A deformable zipper having a ball-headed tape bead, comprising a left tooth chain (1), a right tooth chain (2), a left tape (3), a right tape (4), a slider (5), and a puller (6); both the left tooth chain (1) and the right tooth chain (2) are provided with conical convex members (7) and conical concave members (8), the conical convex members (7) mesh with the conical concave members (8), tooth chain clamping notches (9) are provided in a side orientation of the left tooth chain (1) and the right tooth chain (2), the two tooth chain clamping notches (9) are parallel to each other and have the same opening direction. The present invention improves the bearing strength against the external force of transverse tearing and against the longitudinal dislocation twisting force, the teeth of chain are not easy to be pulled out, lost, or skewed, and the tooth chain is not easy to be separated from the tape or to be displaced, such that the comprehensive physical performance is obviously enhanced, and no arching is caused; when subjected to excessive transverse tension, the zipper is not exploded, and has a strong retaining force; and when the slider is pulled to a turning corner part, the zipper is easily meshed and smoothly pulled, without tearing or stopping.
