Abstract
This disclosure provides a tool or an apparatus that can be held and operated with one hand to attach a corner bead to an outside corner of drywall. In one example, the tool includes a frame, a pair of contact surfaces rigidly coupled to the frame, a handle pivotally attached to the frame, a pair of stapler units rigidly coupled to the frame, and a linkage mechanism comprising a pair of transmission arms and mechanically coupling the handle to the stapler units for translating a force displacing the handle from a first position into a controlled motion of the transmission arms, thereby triggering the stapler units to release fastening pieces.

An apparatus for enabling single-handed attachment of corner beads comprising:
- a frame;
- a pair of contact surfaces rigidly coupled to the frame;
- a handle pivotally attached to the frame;
- a pair of stapler units rigidly coupled to the frame;
- and
- a linkage mechanism comprising a pair of transmission arms and mechanically coupling the handle to the stapler units for translating a force displacing the handle from a first position into a controlled motion of the transmission arms, thereby triggering the stapler units to release fastening pieces.
An apparatus for enabling single-handed attachment of corner beads, the apparatus comprising:
- a frame;
- a pair of contact members, the contact members being formed to define a ridge of the frame;
- a handle pivotably coupled to the frame;
- a support post disposed on the ridge, the support post defining a flat surface facing toward an end of the frame;
- a pair of stapler units disposed on the contact members;
- and
- a force transmission mechanism disposed on the flat surface of the support post, wherein the force transmission mechanism is coupled to an end of the handle to receive a force, and wherein the force transmission mechanism transfers the force from the handle to the pair of the stapler units.
