Magnetic ratchet/clutch type apparatus

摘要

Socket ratchet wrenches and socket combinations using a magnetic ratchet/clutch-type apparatus are disclosed, one of which defines a "through hole" for allowing bolts to pass entirely through the socket and the wrench's head so that a nut can be threaded on a bolt of any length. The wrench's head defines a chamber in which a ratchet wheel is received for rotation relative to the wrench head. The chamber also has pockets for receiving and positioning floating pawls adjacent the wheel to facilitate their movement between a drive position and a release position. A permanent ring magnet is mounted to one side of the wheel for socket retention and magnetically attracting the floating pawls to facilitate the movement of at least one pawl into the drive position in which it is sandwiched between the ratchet wheel and a wall of the pocket to lock the wrench head and the wheel together so that a drive stroke can be made with the wrench.
