Chiropractic adjustor apparatus with rotation hub

摘要

A force-transmitting head for a chiropractic adjustor apparatus includes a hub which is rotatable in a cavity formed in the head and non-rotatably attached to a reciprocating shaft of the apparatus. A rotation pin extends through the body into the cavity and engages a track formed in the hub. Reciprocating movement of the shaft and hub causes a rotational movement of the body with passage of the rotation pin along the track. Also, a chiropractic adjustor apparatus incorporating the force-transmitting head.
