Abstract
A wrench comprises a handle connected to a housing. A socket is rotatably supported in the housing for ratcheting movement relative to the housing. A retaining member releasably secures a device in the socket. A retainer is supported on the housing and is movable between a first position and a second position. The retainer, when in the first position, at least partially overlays the socket. A plurality of guides orient a member relative to the socket. The guides are mounted in a rotatable body. A first handle is permanently connected to the housing and a second handle is removably connected to the housing.
Claims35
A wrench comprising:
- a first handle and a second handle connected to a housing;
- a socket rotatably supported in said housing for ratcheting movement relative to said housing, wherein said socket is located in a body rotatable relative to said housing;
- a plurality of gear teeth surrounding said body;
- a first pawl and a second pawl individually or simultaneously engageable with said gear teeth;
- a camming surface movable relative to said first pawl for pulling said first pawl away from said gear teeth, wherein said camming surface is formed on a rod moveable in a first direction and said working direction being the same direction as the first direction;
- and
- a retaining member for releasably securing a device in said socket, wherein said retaining member moves between a first position and a second position and includes a plurality of spaced apart portions that extend over said device in said second position,
- wherein in said second position, said plurality of spaced apart portions of said retaining member engaging a plurality of faces of said device, each of said faces of said device being spaced apart from each other around the periphery of said device.
