CANVAS STRETCHING TOOL

摘要

Disclosed is a handheld canvas stretching tool used to stretch canvas across a stretcher frame. The tool can include upper and lower jaw plates with slip resistant surfaces configured to firmly grasp a portion of the canvas to be stretched. The tool includes wide “locking pliers” technology, and a second class lever action. These features give the user the mechanical advantage needed to apply a taut stretch to the canvas, while permitting one hand, and sometimes both hands, of the user to be free to apply staples that secure the canvas to the stretcher frame.
