Title: Retention of shank in handle of ratcheting driver
Inventor: EGGERT DANIEL M
IPC: B25B23/00
Filed: 1996-08-16
Abstract: The ratcheting driver comprises an elongated handle having a main body portion and a cap portion rotatable relative to each other about a common longitudinal axis. Rachet mechanism is disposed in a cavity in the handle and engages the mounting end of an elongated shank receivable through a cylindrical axial bore in the cap.
