  • Patent number: 10828758
    Abstract: The present invention relates to a torsion spring winding tool, and in particular to a tool having two bars that are joined with a connector. Each bar can have a shaft with two ends. Two collars are connected to each shaft, generally near the second end of the shafts. The collars separate the bars into three sections, namely a handle, a seat and a lug. A connector is provided and connects the bars together in the seats. The connector can be a spring that is covered with a cover. A user can use the handles to manipulate the bars. The lugs can be inserted into pockets of a spring cone to wind and unwind a torsion spring.
