Rotatable handle for wrench
View Patent ↗A rotatable handle for a wrench includes a fixation rod, a first handle body, and a second handle body. An end of the first handle body is rotatably and axially movably sleeved onto to an end of the fixation rod, and the other end of the first handle body is adapted for being fixed with a wrench head. An end of the second handle body is rotatably and axially movably sleeved onto the other end of the fixation rod, and the other end of the second handle body is adapted for being fixed with another wrench head. Therefore, the relative angle between the two wrench heads can be adjusted appropriately by the relative rotation of the first handle body and the second handle body.
1. A rotatable handle for a wrench, comprising:
a fixation rod;
a first handle body having a first inner end surface, at least two positioning holes recessed inwardly from the first inner end surface, a first outer end surface opposite to the first inner end surface, and a first mounting slot located between the first inner end surface and the first outer end surface, the first handle body being rotatably and axially movably sleeved onto an end of the fixation rod via the first mounting slot; and
a second handle body having a second inner end surface, at least one positioning pillar protruding outwardly from the second inner end surface, a second outer end surface opposite to the second inner end surface, and a second mounting slot located between the second inner end surface and the second outer end surface, the second handle body being rotatably and axially movably sleeved onto the other end of the fixation rod in such a way that each of the at least one positioning pillar is selectively inserted into one of the positioning holes.
2. The rotatable handle as defined in claim 1 , wherein the first mounting slot stepwise extends from the first inner end surface toward the first outer end surface to form a stop surface, and the fixation rod has a rod head and a rod body connected with the rod head; a restoring spring is sleeved onto the rod body and abutted between the rod head of the fixation rod and the stop surface.
3. The rotatable handle as defined in claim 2 , wherein the second mounting slot stepwise extends from the second inner end surface toward the second outer end surface.
4. The rotatable handle as defined in claim 3 , further comprising a first rectangular fixation block and a second rectangular fixation block; wherein the first rectangular fixation block is fixed inside a first rectangular fixation slot that extends from the first outer end surface of the first handle body toward the first inner end surface of the first handle body and is communicated with the first mounting slot of the first handle body; the second rectangular fixation block is fixed inside a second rectangle fixation slot that extends from the second outer end surface of the second handle body toward the second inner end surface of the second handle body and is communicated with the second mounting slot of the second handle body.
5. The rotatable handle as defined in claim 1 , wherein the first handle body comprises four said positioning holes arranged around the first mounting slot equiangularly.
6. The rotatable handle as defined in claim 1 , wherein the second handle body comprises at least two said positioning pillars corresponding in number to the at least two positioning holes of the first handle body.
