1. Field of the Invention
The invention relates to hand tools, and in particularly to a multi-purpose hand tool having a plurality of shafts such as screw driver blades or bits.
2. Description of the Prior Art
Presently there are multi hand tools well known in the tool art. There are known various tool sets comprised of a handle and a set of tool bits adapted for attaching to the handle. These tool sets must be carefully received in a tool box or the like when not in use. Because the tool bits of a tool set are separately received, they tend to be lost in the work place.
In order to solve the existing above mention problem in a conventional hand tool set, the innovative structure of the present invention mitigates this problem.
It is a first object of the present invention to provide the user an innovated structure for hand tools which keeps a set of tool bits retained together to be conveniently selected when needed.
It is a second object of the present invention to provide the user an innovated structure for hand tools which enables tool bits that can be alternatively turned between the operative position and the non-operative position.
It is the third object of the present invention to provide the user an innovated structure for hand tools which prevents the tool bits their loss as is frequently experienced with other conventional hand tools.
The drawings disclose an illustrative description of the invention by way of reference with the preferred embodiment.
Referring to the drawings and its numbers in order to promote an understanding of the preferred embodiment this invention is a hand tool designed to loosen or tighten screws.
The hand tools main body is a substantially cylindrical storage handle 11 which has a plurality of longitudinally extending tool storage slots 8 and each tool storage slots 8 accommodates tool blades 5 as shown in
Each tool blades end 6 is specifically designed to interact with different screw heads as shown in
The tool blades 5 are attached to the storage handle 11 at the opposite end of the tool blades end 6 by a pin 1 which runs through and is perpendicular to the tool blades 5 longitudinal axis 28 and is embedded into the storage slot wall 2 at the storage handle head 3 which acts a pivot point for the tool blades 5 as shown in
There is a housing head 4 which is connected by a bolt 15 and thread 30 to the storage handle 11 through a central axis hole 16 at the end of the storage handle end 3 and held snug by a spring 18 as shown in
The housing head 4 has indents 12 which rests in the tool storage slots ends 14 of the storage handle head 3 which prevents the housing head 4 to rotate 9 perpendicular to the longitudinal axis 28 of the storage handle 11 as shown in
When one of the tool blades 5 is not in a storage position 24 it becomes a selected tool blade 25 the housing head 4 holds the selected tool blade 25 in place during an operative mode as shown in
In order to put one of the tool blades 5 from the storage handle 11 into an operative mode for a certain type of screw head the housing head slot 7 must be inline with your selected tool blade 25 tool storage slot 8 as shown in
In order to put the housing head slot 7 inline with the selected tool blade 25 tool storage slot 8 the housing head 4 can pulled away 10 from the storage handle 11 freeing the indents 12 from the tool storage slots ends 14 and allowing the housing head 4 to rotate 9 perpendicular to the longitudinal axis 28 of the storage handle 11 until the housing head slot 7 and the selected storage slot 8 are aligned as shown in
The housing head 4 when released it is pulled back 20 on the storage handle head 3 by the spring 18 as shown in
The housing head 4 indents 12 will rest back on the tool storage slots ends 14 locking the housing head 4 in place on the storage handle 11 for the operative mode as shown in
A cavity 21 at the end of the storage handle 11 allows the operators finger to pull the selected tool blade 25 out of the tool storage slot 8 as shown in
The selected tool blade 25 can be rotated 180 degrees 22 into the housing head slot 7 creating an operative position for the selected tool blade 25, the housing head 4 is ridged when locked in place on the storage handle 11, and this prevents circumferential twisting of the selected tool blade 25 when force is applied during use as shown in
The housing head has a locking screw 23 which is perpendicular to the selected tool blade 25 longitudinal axis this prevents the selected tool blade 25 from slipping out of the housing head 4 when in operation as shown in
After use the selected tool blade 25 can be unlocked and rotated back into the tool storage slots 8 as shown in
The storage handle head 3 of the storage handle 11 indents into the housing head 4 because of a housing head flaring 26 on the housing head 4 that extends circumferentially around the storage handle head 3 of the storage handle 11 and over top of the tool blade 5 pin 1 ends which prevents the unselected tool blades 5 from being extracted out of the tool storage slots 8 as shown in
The housing head slot 7 cuts into the housing head flaring 26 which allows for a passageway for a selected tool blade 25 as shown in
Those skilled in the art to which this invention relates too are able to do variations in its practice and modes of construction. Thus this invention is not intended to be limited by the illustrative description presented hereinabove, but should be encompassed in the spirit and scope of the appended claims.
