Retention of shank in handle of ratcheting driver

摘要

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. Diametrically opposed projections project radially outwardly from the shank so as to prevent free passage through the bore, the projections being harder than the cap to permanently deform the cap and permit passage of the shank through the bore for engagement with the ratchet mechanism, the projections being freely received in the cavity to retain the shank in the handle while permitting rotation of the shank relative to the cap. Either of two types of washers may be disposed between the projections and the cap to prevent the projections from rubbing against the deformations of the cap during rotation.
