Storage type hexagonal socket wrench

Claim 1

A storage type hexagonal socket wrench comprising a handle for manual operation of said wrench, a driving shaft having a front portion, a rear portion and a hexagonal rod-like configuration, control means located on said handle and selectively connecting said rear portion of said driving shaft for either clockwise or counterclockwise rotation of said driving shaft, a socket having a front portion, a rear portion and a hexagonal outer configuration, said socket having a hexagonal hole in the rear portion thereof which receives said front end of said driving shaft, said socket also having a pentagonal hole in said front portion, an opening being positioned between said pentagonal hole and a first exterior side of said socket, said opening having a steel ball and an elastic element located therein, a longitudinal groove is located on a second exterior side of said socket which is parallel to said first exterior side, a back seat having a front face, a rear face and comprising a circular block, a hexagonal tube extending from said rear face and slidably receiving said socket therein, said hexagonal tube having a flange to form a reduced hexagonal hole for insertion of said driving shaft, an axle being integral with said back seat and extending from a central portion of said front face, a rotatable storage wheel having a center is rotably mounted on said axle, a plurality of hexagonal holes having front and rear ends are located equidistantly around said center of said rotatable storage wheel, a stop lug being located on said rotatable wheel at the rear end of each hexagonal hole, a front seat having a front face, a rear face and comprising a circular block, a hexagonal tube extending from said front face of said front seat, said hexagonal tube having a flange protruding inward to form a reduced hexagonal hole, bolt means for connecting said front seat and said rear seat together, a set of socket wrench elements being positioned in said plurality of hexagonal holes in said rotating storage wheel, each of said wrench elements having a hexagonal central portion of a size suitable for sliding in said plurality of hexagonal holes and in the hexagonal tube of said front seat, each of said wrench elements also having a rear portion for insertion in said socket, said rear portion being a pentagonal post with a slot therein for receiving said steel ball to firmly fix the connection after said rear portion is inserted into said pentagonal hole of said socket, whereby the following procedure may be followed in order to select a desired wrench element, the driving shaft is pulled backward to let said socket be separated from the pentagonal post of an engaged wrench element so that the driving shaft is positioned in the hexagonal tube of said back seat while the hexagonal central portion of the wrench element is stopped by a stop lug of said rotatable wheel and retained inside thereof, then said rotatable wheel is revolved so that the selected socket wrench element is aligned with the hexagonal tube of said back seat, then, said driving shaft is pushed forward to drive the pentagonal post of the selected socket wrench element, thereafter, said driving shaft is continuously pushed forward so that the desired socket wrench element is forced to protrude beyond the hexagonal hole of said front seat to form an operative hexagonal socket wrench.
