Abstract: A table saw includes a movable rip fence and a base including an upper cutting surface through which a blade extends. The rip fence includes front and rear clamping mechanisms connected to front and rear ends of a casing respectively. The front clamping mechanism includes a frame, a lever pivotably secured to the frame to be pivotal between a locked position and a released position, the lever having an internal cam member, a clamping member pivotably secured to the lever, the clamping member having a hook at an open end, a spring biased shaft, and a C-clip for retaining an inner end of the shaft in the frame. A pivotal movement of both the lever and the clamping member causes the cam member to push the shaft inward until the shaft is pushed outward to urge against the cam member in the locked position.
