Abstract
A hand tool for tightening or loosening a threaded cylindrical member relative to a corresponding threaded socket, including a generally rectangular wrench body which contains a generally circular opening for coaxially receiving the cylindrical member, a generally disk-shaped locking cam that is moveably connected with the wrench body for displacement between extended and retracted positions extending within and withdrawn from the circular opening, respectively, thereby clamping the threaded cylindrical member when the locking cam is extended into the circular opening, and a handle member operable when the cam is in the extended position to rotate the wrench body with the cylindrical member clamped thereto relative to the threaded socket.
Claims13
A hand tool for tightening and loosening a threaded cylindrical first member (5) relative to a corresponding threaded socket (19), comprising:
- (a) a generally rectangular wrench body (1) containing a generally circular opening (4) for coaxially receiving the first member;
- (b) a generally disk-shaped locking cam (6) moveably connected with said body for displacement between extended and retracted positions extending within and withdrawn from said opening, respectively, the surfaces of said cam and said opening being operable to grip the outer periphery of the first member when said cam is in said extended position, thereby to clamp said wrench body to the first member;
- and
- (c) handle means (2) operable when said locking cam is in said extended position for rotating said wrench body about the axis of said opening, thereby to rotate the first member in a first direction relative to the socket.
