The socket has a hexagonal outer configuration and a hexagonal hole in one end to receive the shaft and a pentagonal hole in the front portion. The back seat comprising a circular block having a hexagonal tube extended therefrom. The hexagonal tube having a hexagonal opening for the socket to slide thereinside, and a flange at the rear end to protrude inward so as to form a reduced hexagonal hole for insertion of said driving shaft, an axle extends from the central portion of the circular block. A rotatable storage wheel having a hole for insertion therethrough of the axle in a manner that the rotatable storage wheel is revolvably mounted on the back seat, six hexagonal holes are equidistantly positioned around the hole with a respective stop lug at the rear end of each hexagonal hole. The front seat being a circular block having a hexagonal tube horizontally extended therefrom with a flange protruding inward to form a reduced hexagonal hole. The front seat and the back seat are secured together. The socket wrench elements each have a hexagonal central portion which is slidable in a hole of the rotatable storage wheel and in the hexagonal tube of the front seat and a pentagonal post with a slot therein to receive a steel ball in order to provide a connection with the pentagonal hole of the socket.
