ABSTRACT:
A hand tool particularly adapted for compressing an automobile shock absorber spring to facilitate repairs. The tool comprises a handle with a hook pivoted at the end thereof adapted to engage under a spring coil. An arm is pivoted near one end thereof intermediate the ends of the handle, and a downwardly facing hook on the end of the arm is adapted to engage over a higher coil of the spring. By pushing the handle with the hooks engaged, the hooks or jaws are brought closer together and a short extension of the arm swings across the handle, camming back a lock sleeve slidable thereon. When the arm extension and handle are in alignment, the lock sleeve is extended by a small spring to enclose the arm extension and prevent movement thereof. The compressed coil spring exerts a force on the jaws trying to separate them. This forces the arm extension tightly against the inner surface of the lock sleeve, holding the sleeve firmly in place against inadvertent retraction.
