[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] When it is rolled to a certain extent, the backward movement speed of the bead head slows down, but the rotation speed remains unchanged. At this time, the second steel wire clamp moves a short distance toward the bead head, so that the tail of the steel wire twist is close to the tail of the twist, and the tail of the twist is perpendicular to the wire core. The bead head continues to rotate, but moves backward very slowly. Under the action of the rotational force, the tail of the twist is rolled into a ring around the wire core, which is the rolled tail of the twist. BRIEF DESCRIPTION OF THE DRAWINGS
