Abstract:
A tool for grasping a ratchet socket or other objects such as pipes and rods. The object can be stopped from turning due to the friction of the tool or the object can be rotated when desired. The tool comprises a flexible friction belt connected at one end to an open jaw which may be closed and connected at its other end to a spring biased rod or movable handle. In one embodiment a slidable trigger is connected to the spring biased rod to permit a loop in the flexible belt to be enlarged for slipping around a socket or other object. When the trigger is released the loop grips the socket and frictionally holds the socket while closing the jaw. In a second embodiment the flexible friction belt connects to a handle which is slidably held in an outer housing. The handle may be moved to open and close a loop in the friction belt. An automatic lock is provided in the housing so the friction belt will turn the object being held as the belt loop is enlarged and made smaller. Both embodiments provide a lever connected to the jaw so the jaw may be pulled toward the housing to close the belt loop opening.
