Claims2
A ratchet wrench of the socket drive type with socket ejector comprising:
- a. a handle having a lever portion and a head portion, with the head portion having a central bore with internal spline-like teeth formed therein and oppositely disposed side faces;
- b. a ratchet plug assembly installed in the head portion of said handle and including:
- i. a ratchet plug with a body portion having an integral socket drive stud protruding axially outwards beyond one of said head portion side faces, an axial cylindrical recess opening to the body portion end opposite said socket drive stud, and a pair of spaced parallel ejector pin bores extending through said body portion and adjacent to respective side margins of said socket drive stud and opening to said axial cylindrical recess;
- ii. ratchet pawl means for driving or ratcheting on said spline-like teeth and reversing means therefor;
- iii. a control knob disposed in said axial cylindrical recess for reciprocable movement therein, with said control knob having a head portion which has an inner face and a stub shaft portion extending axially inward from said inner face;
- iv. an ejector pin retainer plate disposed on said stub shaft adjacent said inner face;
- and,
- v. a pair of ejector pins carried by said retainer plate and disposed in said ejector pin bores, with said ejector pins bearing at one end on said inner face and restrained by said retainer plate against movement in the direction away from said inner face.
