Abstract
An adjustable handle is attached to a power tool having a tool head and a motor housing. When the handle is loosened, the tool head can rotate relative to the motor housing and the handle can be rotated relative to the power tool. When the handle is tightened, the tool head does not rotate relative to the motor housing and the handle does not rotate relative to the power tool. The adjustable handle allows the user to easily reconfigure the power tool for use in confined spaces or special applications.
Claims20
An adjustable power tool comprising:
- a handle coupled to a threaded rod;
- a power tool housing;
- a locking mechanism coupling the handle to the housing, the locking mechanism comprising:
- a cam having a curved surface, a first hole and a second hole wherein the first hole and second hole intersect;
- an axle having a threaded hole wherein the axle is mounted within the second hole of the cam;
- a plunger that is mounted between the power tool housing and the curved surface of the cam;
- and
- a collar that is coupled to the axle and surrounds a portion of the power tool housing;
- wherein the threaded rod is coupled to the threaded hole in the axle and when the threaded rod is rotated in a first direction within the threaded hole, the collar and handle can rotate around a center axis of the power tool and when the threaded rod is rotated in a second direction within the threaded hole, the collar tightens around the power tool housing and the cam presses the plunger against the power tool housing locking the handle against rotation.

An adjustable power tool comprising:
- a power tool housing;
- a collar that is attached to the power tool housing;
- a locking mechanism that is coupled to the collar;
- and
- a handle that includes a threaded rod that is coupled to the locking mechanism;
- wherein when the threaded rod is rotated in a first direction relative to the locking mechanism, the collar is movable around the power tool housing and the handle is movable relative to the power tool and wherein when the threaded rod is rotated in a second direction relative to the locking mechanism, the locking mechanism tightens the collar around the power tool housing preventing the collar from moving around the power tool housing and locking the handle in place preventing the handle from moving relative to the power tool housing.
