Abstract

A hand tool set includes an elongated handle having a U-shaped cross section defined by a bottom and two side walls to provide therebetween a hollow space. The handle has two ends each having a pin extending through the side walls thereof for rotatably supporting hand tools in such a way to allow the hand tools to be rotatable between a first position where the hand tools are received within the hollow space and a second position where the working tips of the hand tools are exposed. The bottom has a sloped section formed at each end of the handle to provide a gap between the handle and a work piece worked upon by the hand tool set. Each of the pivot pins has serration formed on an expanded head thereof for engaging one of the side walls to more securely keep the pin and thus the hand tools supported thereby on the hand tool set.

Claims

1. A hand tool set comprising an elongated handle having a U-shaped cross section defined by a bottom and two side walls mounted to the bottom to provide a hollow space therebetween, said handle comprising two ends each having a pivot pin extending through the side walls thereof for rotatably supporting a number of hand tools thereon to allow the hand tools to be rotatable between a first position where the hand tools are completely received within the hollow space of said handle and a second position where working tips of the hand tools are exposed, and

the improvement comprising a number of polygon holes formed on the bottom of said handle and a sloped section formed on the bottom at least one of the ends of said handle to provide a gap between the handle and a work piece worked upon by said hand tool set.

2. A hand tool set as claimed in claim 1 wherein the bottom of said handle has a sloped section formed at each of the ends of said handle.

3. A hand tool set as claimed in claim 1 wherein each of the pivot pins has an expanded head with serration formed thereon for more securely keeping the pivot pin and the hand tools supported thereby on said handle.

4. A handle tool set as claimed in claim 3 wherein said pivot pin comprises a bolt secured on said handle by a nut member.

5. A handle tool set as claimer in claim 1 wherein each of the pivot pins has a spring washer mounted thereon within the hollow space of said handle to provide a biasing force for tightly holding the hand tools in the first position within the hollow space of said handle.
