1. An angle-adjustable power tool comprising a handle, a driving head, and a positioning group, wherein:
the handle has
an engaging mount mounted in a top of the handle and having
a communicating recess formed in the engaging mount; and
a fixing recess formed in the engaging mount, communicating with the communicating recess, and faced to the driving head; and
an engaging disk mounted in the fixing recess of the engaging mount;
the driving head is pivotally connected to the handle and has
a pivot base disposed in a bottom of the driving head and rotatably connected to the handle to dispose the engaging mount and the engaging disk between the handle and the pivot base; and
a head portion disposed on a top of the driving head and connected to the pivot base; and
the positioning group is disposed between the handle and the driving head to fix an angle of the driving head relative to the handle, and has
a positioning mount rotatably and movably disposed between the handle and the pivot base, and selectively engaging with the engaging disk;
an elastic element disposed in the communicating recess of the engaging mount and abutting against the positioning mount to push the positioning mount to engage with the engaging disk;
an abutting mount disposed on an external surface of the handle opposite to the pivot base, connected securely to the engaging mount, and abutting against the elastic element, the abutting mount having at least one sliding slot formed in an external surface of the abutting mount; and
a toggling element connected to the positioning mount and rotatably abutting the abutting mount, the toggling element having at least one protrusion formed on and protruding from a side of the toggling element facing the abutting mount, and being selectively mounted in the at least one sliding slot or abutting against the external surface of the abutting mount to move the positioning mount relative to the engaging disk with the rotation of the toggling element;
wherein the toggling element is rotated relative to the abutting mount, the positioning mount is moved by the toggling element to separate from the engaging disk and to compress the elastic element, an angle of the driving head relative to the handle is adjusted via the pivot base, after angle-adjustment, the positioning mount is moved toward and engages with the engaging disk for positioning by the compressed elastic element.
