Claim:
A socket wrench, comprising: a head part having a chamber formed therein; a rotating head disposed in the chamber of said head part; a metallic handle having an accommodating chamber formed therein, and which is accessible through an opening located at a rear end of said handle, said handle having an axially-arranged ring-shaped slot disposed at a front end of said handle, said handle further having a flexible spring piece disposed in a region of the rear end of said handle, and a locking hole formed on a wall of the accommodating chamber and adjacent to the flexible spring piece; a metallic rotating rod having an end integrally attached to the front end of said handle to form a unitary, one-piece construction, and being axially-disposed inside of the ring-shaped slot, said handle being coupled to said rotating head by way of said metallic rotating rod, said handle and rod being movable both in a reciprocating manner to output a torque force, and being axially rotatable about a fixed point to output a further torque force, to cause said rotating head to rotate; and a pending platform, including: a long rod seat body that is configured to have a cylinder shape that is divided lengthwise in half so as to be semi-cylindrical, so that a cross-section thereof has a semi-circular shape of about 180 degrees, and which is removably insertable into the accommodating chamber by way of the opening located at the rear end of said handle, said seat body being formed with a plurality of separated slot seats each having a different dimension for respectively accommodating a different sized socket, said seat body further including a plurality of projecting pieces, each being formed on a side wall of a respective slot seat, each said projecting piece projecting radially inward, and pressing against a respective socket received within the respective slot seat, to retain the socket within the slot seat; and a cover part disposed at an end of said seat body and which covers the opening located at the rear end of said handle, when said semi-cylindrical long rod seat body is inserted into the accommodating chamber, said cover part including a flexible spring piece having a locking piece disposed thereon, the locking piece being receivable within the locking hole formed on the wall of the accommodating chamber, to secure said seat body within the accommodating chamber, the locking piece being released from the locking hole by pressing the flexible spring piece on said handle, which consequently presses against and moves the flexible spring piece of said cover part, to thereby move the locking piece from the locking hole, the flexible spring pieces, the locking piece and the locking hole being positioned relative to the slot seats so that when they are located facing upwards, the respective slot seats will also all face upwards, thereby ensuring the respective sockets will not inadvertently drop from the respective slot seats, when a user removes the seat body from the accommodating chamber.
