Abstract
An improved structure of the driving axis of a puller includes a screw bar, a driving assembly with a through hole, and a driven assembly underneath the driving assembly, with a screw hole. A plurality of connecting arms is disposed in the radial direction of the driven assembly. The screw bar penetrates downward through the driving assembly and the driven assembly with its bottom end, while its top end is provided with a rotating element for mounting a tool to rotate the screw bar. With a positioning element penetrated the rotating element into the screw bar, the rotating element is fixed on the screw bar for simultaneous rotation.

An improved structure of the driving axis of a puller, comprising a screw bar, a driving assembly, and a driven assembly;
- wherein the screw bar has a top end and a bottom end, the driving assembly has a through hole, the driven assembly has a screw hole, the driven assembly is disposed underneath the driving assembly, the bottom end of the screw bar penetrates downward through the through hole of the driving assembly and the screw hole of the driven assembly, and the improved structure is further characterized in that:
- the top end of the screw bar has a rotating element for mounting a tool to rotate the screw bar;
- the rotating element has a space corresponding to the top end of the screw bar;
- one side of the rotating element is formed with a connecting hole connecting to the space;
- the screw bar has a positioning hole corresponding to the connecting hole;
- and a positioning element goes through the connecting hole and gets positioned in the positioning hole, thereby fixing the rotating element on the screw bar to rotate concurrently with the screw bar.
