Wrench apparatus

A slide lock mechanism designed to work with a tool, said tool comprising a body with a recess and a head with an opening and a handle, said mechanism comprising:

• at least one lock plate, at least one release plate and at least two rollers, each of said lock and release plates comprising at least one spring holding compartment, at least one central opening and at least two cutouts, said mechanism having a contact element, at least a portion of said contact element contacting a portion of said lock plate, said lock plate is situated above said release plate and said openings and cutouts of each of said plates are aligned with one another and inserted with the recess of said body, said mechanism further comprising at least two rollers and at least one spring, at least a portion of each of said rollers are situated within said cutouts of said plates, at least a portion of said spring is situated within said spring holding compartment of said plates, said spring causes said rollers to engage said opposing walls of said recess of said body, said mechanism further comprises at least one button having a top contact surface and a bottom protrusion, at least a portion of said protrusion is designed to be situated within said central openings of said release and lock plates, whereby said slide lock mechanism functions based on movement of said button, said button has two positions, a first operating position and a second non-operating position, when said button is in a non-operating position said rollers are urged against said angled locking surface of said cutouts thereby wedging said rollers against said sidewalls of said recess preventing the contact element from moving towards the handle.
