Abstract

An improved universal tool structure having a handle holding a tool head connecting means for receiving one of a plurality of tool heads, and a tool head storage case body held within the handle. A push button on the outer surface of the handle has a control member and a biasing spring within the handle. The storage case body fits into the handle from the bottom and has an elongated hole or slot at its top for receiving the control member which is biased to press against the inner surface of the hole to retain the storage case body in the handle. The case body is released by pressing the push button, and a flange at the top of the storage case body butts against an inwardly projecting flange at the handle bottom to retain the case body in the handle.

Claims

1. A universal tool comprising:

a handle formed of two substantially symmetrical concave portions joined so as to form a hollow interior space therebetween, said handle including a tool head connecting means projecting from one end thereof and having an opening in an opposite end;

tool head storage case body movably positioned in said handle interior space to extend outwardly through said end opening, said case body having means for accommodating tool heads therein and having an L-shaped opening formed in an intermediate portion of an inner end wall;

a control member movably attached to a lateral interior wall of said handle in a position corresponding to a path of movement of said L-shaped opening so that said control member will pass into said L-shaped opening so said case body is moved into said handle;

a biasing spring mounted on an inner wall of said handle so as to press said control member to engage a side of said of L-shaped opening to thereby retain said case body in said handle; and

a push button movably provided on an exterior wall of said of said handle and having a member extending through said handle to engage said control member, said push button urging said control member against said biasing spring to release engagement with said case body to allow movement of said body out of said handle end opening.

2. A universal tool as recited in claim 1 further comprising a first flange formed on said case body inner end wall and a second internally projecting flange formed at said handle end opening so as to abut said first flange and prevent removal of said case body from said handle.
