Abstract
A saw blade clamping device has a first clamping device for clamping a first working element and a second clamping device for clamping a second clamping element, wherein the first clamping device and the second clamping device are parallel to each other and mounted to a transmission controlling mechanism. The two clamping devices can be controlled by the transmission control mechanism to can not only clamp a single saw blade but to allow for replacement of the single saw blade by double saw blades without changing the clamping system, which enables the replacement of the saw blade to be more convenient and quick.
