The invention provides a cable laying manual traction auxiliary tool comprising a handle, a support transverse plate, an upper compacting device, and a lower support device. The handle is hinged to one end portion of the support transverse plate. A threaded through hole is disposed on the center of the support transverse plate. A threaded rod in the upper compacting device is sleeved by the threaded through hole. An inverted-T-shaped connection rod in the lower support device is disposed on one end of the support transverse plate and is located under the handle. The cable laying manual traction auxiliary tool is simple in structure and easy to carry. The upper compacting device and the lower support device may not only clamp a cable firmly in a used process, but also fundamentally eliminate a torsion problem in a manual cable laying process.
