Abstract

A tool includes a handle device having a shank for driving tool members, and having a primary hand grip. An auxiliary hand grip is selectively attached to the primary hand grip, to increase a length of the tool by combining both the auxiliary hand grip and the primary hand grip together, and the auxiliary hand grip may be selectively detached from the barrel of the handle device, to decrease the length of the tool to only the primary hand grip. A tool device may further be received in the auxiliary hand grip, and removable from the auxiliary hand grip, for driving tool elements having a dimension smaller than that of the tool members. A casing may be secured to the auxiliary hand grip, to receive a tape measuring device.

Claims

1. A tool comprising:

a handle device including a shank extended forwardly therefrom, for engaging with and for driving tool members, and including a primary hand grip provided thereon and having a space formed therein,

an auxiliary handgrip including a protrusion extended therefrom, and selectively engageable into said space of said primary hand grip, to selectively attach said auxiliary hand grip to said primary hand grip of said handle device, and to increase a length of said tool by combining both said auxiliary hand grip and said primary hand grip together, and said auxiliary hand grip being selectively detachable from said primary hand grip of said handle device, to decrease the length of said tool to only said primary hand grip, and said auxiliary hand grip including a chamber formed therein, a cover attached to said auxiliary hand grip to enclose said chamber of said auxiliary hand grip, a casing secured to said cover, said casing including an opening formed therein, a tape measuring device received in said casing and having a tape, said tape including a free end portion engageable through said opening of said casing, and

a tool device received in said chamber of said auxiliary hand grip, and removable from said auxiliary hand grip, for driving tool elements having a dimension smaller than that of said tool members.

2. The tool as claimed in claim 1, wherein said tool device includes a driving stem having a chamber formed therein to receive said tool elements therein.

3. The tool as claimed in claim 2, wherein said driving stem includes an cap attached thereto, to enclose said chamber thereof and to stably retain said tool elements within said chamber thereof.

4. A tool comprising:

a handle device including a shank extended forwardly therefrom, for engaging with and for driving tool members, and including a primary hand grip provided thereon and having a space formed therein,

an auxiliary hand grip including a protrusion extended therefrom, and selectively engageable into said space of said primary hand grip, to selectively attach said auxiliary hand grip to said primary hand grip of said handle device, and to increase a length of said tool by combining both said auxiliary hand grip and said primary hand grip together, and said auxiliary hand grip being selectively detachable from said primary hand grip of said handle device, to decrease the length of said tool to only said primary hand grip, and said auxiliary hand grip including a chamber formed therein, and

a tool device received in said chamber of said auxiliary hand grip, and removable from said auxiliary hand grip, for driving tool elements having a dimension smaller than that of said tool members, and

said auxiliary hand grip a tool holder received in said chamber thereof, and including a cover attached thereto, to enclose said chamber thereof and to stably retain said tool holder in said chamber of said auxiliary hand grip.

5. The tool as claimed in claim 4, wherein said tool holder includes a plurality of orifices formed therein, for receiving said tool members therein.

6. The tool as claimed in claim 5, wherein said tool holder includes a plurality of slits formed therein, and communicating with said orifices thereof, to resiliently clamping and retaining said tool members to said tool holder.

7. The tool as claimed in claim 4, wherein said tool holder includes a bore formed therein, said tool device includes a driving stem received in said bore of said tool holder.

8. A tool comprising:

a handle device including a shank extended forwardly therefrom, for engaging with and for driving tool members, and including a primary hand grip provided thereon and having a space formed therein,

an auxiliary hand grip including a protrusion extended therefrom, and selectively engageable into said space of said primary hand grip, to selectively attach said auxiliary hand grip to said primary hand grip of said handle device, and to increase a length of said tool by combining both said auxiliary hand grip and said primary hand grip together, and said auxiliary hand grip being selectively detachable from said primary hand grip of said handle device, to decrease the length of said tool to only said primary hand grip, and said auxiliary hand grip including a chamber formed therein, and

a tool device received in said chamber of said auxiliary hand grip, and removable from said auxiliary hand grip, for driving tool elements having a dimension smaller than that of said tool members, said tool device including a driving stem having a chamber formed therein to receive said tool elements therein, said driving stem including a cap attached thereto, to enclose said chamber thereof and to stably retain said tool elements within said chambers thereof, and

said auxiliary hand grip including a cover attached thereto, to enclose said chamber thereof, and having a cavity formed therein and defined by a peripheral fence, said driving stem including an enlarged head formed on said end cap and engaged in or reseated within said cavity of said cover.

9. A tool comprising:

a handle device including a shank extended forwardly therefrom, for engaging with and for driving tool members, and including a primary hand grip provided thereon and having a space formed therein,

an auxiliary hand grip including a protrusion extended therefrom, and selectively engageable into said space of said primary hand grip, to selectively attach said auxiliary hand grip to said primary hand grip of said handle device, and to increase a length of said tool by combining both said auxiliary hand grip and said primary hand grip together, and said auxiliary hand grip being selectively detachable from said primary hand grip of said handle device, to decrease the length of said tool to only said primary hand grip, and said auxiliary hand grip including a chamber formed therein, and

a tool device received in said chamber of said auxiliary hand grip, and removable from said auxiliary hand grip, for driving tool elements having a dimension smaller than that of said tool members, said tool device including a driving stem having a chamber formed therein to receive said tool elements therein, and

said driving stem including an orifice formed therein and defined between at least two spring blades, for receiving either of said tool elements therein, and a control ferrule threaded onto said driving stem, for selectively forcing said spring blades toward each other, in order to detachably clamp and secure said tool element to said driving stem, and to allow said tool element to be rotated or driven by said driving stem.
