Hand tool with pivotable head
View Patent ↗A hand tool includes a handle and a head which includes a protrusion having a toothed portion. The handle includes a connection portion formed on one end thereof. Two lugs extend from the connection portion to form a recess between the two lugs and the connection portion. Two ribs respectively extend from the connection portion and ARE located between the two lugs. The two ribs are integral with the two lugs and the connection portion. The protrusion of the head is pivotably connected between the two lugs and the toothed portion is engaged with a control unit located in the recess. The two ribs restrict the angle that the head is pivoted relative to the handle.
1. A hand tool comprising:
a head having a protrusion extending therefrom, the protrusion having a toothed portion;
a handle having a connection portion formed on one end thereof, two lugs extending from the connection portion so as to form a recess between the two lugs and the connection portion, two ribs respectively extending from the connection portion and located between the two lugs, the two ribs being integral with the two lugs and the connection portion, the protrusion of the head pivotably connected between the two lugs, and
a control unit located in the recess and engaged with the toothed portion, the two ribs restricting an angle that the head is pivoted relative to the handle.
2. The hand tool as claimed in claim 1 , wherein a first axis passes through a center of an inner end of the recess, a second axis extends along a top of each of the ribs, a restriction angle is formed between the first axis and each of the second axes, the restriction angle is between 60 degrees to 75 degrees, including 60 degrees and 70 degrees.
3. The hand tool as claimed in claim 2 , wherein the protrusion of the head and each of the two lugs has a hole, a pin extends through the holes of the protrusion of the head and each of the two lugs to pivotably connect the protrusion of the head between the two lugs.
4. The hand tool as claimed in claim 1 , wherein the protrusion of the head and each of the two lugs has a hole, a pin extends through the holes of the protrusion of the head and each of the two lugs to pivotably connect the protrusion of the head between the two lugs.
5. The hand tool as claimed in claim 1 , wherein the ribs each have a first height, the two ribs each have a second height which is higher than the first height.
