Abstract: A bed-type circular saw blade grinder includes: a bed section; a support section fixedly connected with the bed section, a circular saw blade being rotatably connected with the support section; a rotary seat pivotally disposed on the bed section via a pivot shaft and reciprocally rotatable about the pivot shaft between a first position and a second position, the rotary seat having a first connection section and a second connection section positioned on two sides of the pivot shaft; a circular saw blade restriction section disposed at the first connection section for driving the circular saw blade to intermittently rotate; and a grinding unit disposed at the second connection section for grinding saw teeth. When the rotary seat is pivotally rotated between the first and second positions, the rotary seat drives the circular saw blade restriction section and the grinding unit to move with the rotary seat.
