Foldable hand tool
A foldable tool includes a first rod member, a second rod member and a pivoting device. The first rod member has a first length. The second rod member has a second length. The pivoting device is arranged between the first rod member and the second rod member. The first rod member and the second rod member are configured to be selectively pivotable to each other via the first pivoting device. A ratio of the first length to the second length is in a range between 1.1 and 6.
1. A foldable hand tool comprising:
a first rod member having a first distal end, a first proximal end opposite to the first distal end and a first length defined between the first distal end and the first proximal end;
a second rod member having a second distal end, a second proximal end opposite to the second distal end and a second length defined between the second distal end and the second proximal end, wherein a ratio of the first length to the second length is in a range between 1.1 and 6, and wherein the second rod member is provided with a working portion disposed at the second distal end;
a first pivoting device arranged between the first proximal end and the second proximal end, wherein the first rod member and the second rod member are configured to be selectively pivotable to each other via the first pivoting device; and
a second pivoting device arranged between the second distal end and the working portion, wherein the second distal end and the working portion are configured to be selectively pivotable to each other via the second pivoting device, wherein the second pivoting device includes a third pivoting member and a fourth pivoting member pivotally coupled to the third pivoting member, wherein the third pivoting member is fixed to the second distal end, and wherein the fourth pivoting member is formed at the working portion.
2. The foldable hand tool as claimed in claim 1 , wherein the ratio of the first length to the second length is in a range between 1.9 and 3.
3. The foldable hand tool as claimed in claim 1 , wherein the ratio of the first length to the second length is in a range between 3 and 4.
4. The foldable hand tool as claimed in claim 1 , wherein the ratio of the first length to the second length is in a range between 4 and 6.
5. The foldable hand tool as claimed in claim 1 , wherein the working portion is a gooseneck crowbar head, a 90 degree angled crowbar head, or an oblique crowbar head.
6. The foldable hand tool as claimed in claim 1 , wherein the first rod member and the second rod member are respectively hollow.
7. The foldable hand tool as claimed in claim 6 , wherein the first rod member is provided with a cover member mounted at the first distal end and a slip-proof portion formed on an outer periphery thereof and adjacent to the cover member.
8. The foldable hand tool as claimed in claim 1 , wherein the first pivoting device includes a first pivoting member and a second pivoting member pivotally coupled to the first pivoting member, wherein the first pivoting member is fixed to the first proximal end of the first rod member via a first fastening device, wherein the second pivoting member is fixed to the second proximal end of the second rod member via a second fastening device, and wherein the first pivoting member and the second pivoting member are configured to be switchable between a locked position and an unlocked position to selectively pivot relative to each other about a pivoting axis.
9. The foldable hand tool as claimed in claim 8 , wherein each of the first fastening device and the second fastening device includes two fastening holes and a fastener fixedly inserted through the two fastening holes.
