Hacksaw with Blade Tensioning Mechanism |
摘要 |
A hacksaw with an improved mechanism for applying and adjusting the tension on a blade mounted to a blade mount on a front arm and a blade mount on a rocker arm. The rocker arm is pivotally coupled to a handle and is spring biased to place an initial tension on a blade held by the rocker arm and the front arm. A rotatably mounted lever is positioned on the handle for vertically displacing a nut captured in the rocker arm to pivot the rocker arm and adjust the tension on the rocker arm-held blade. An elongate top frame bar of the hacksaw defines a hollow I-beam cross-section accessible from the face of the front handle and is capable of storing saw blades. A bale screw is positioned in the front member for securing the blades in a position extending past the front handle.
