Compound saw

According to the compound saw, a beveling station used for beveling is arranged on a base, a table cutting station used for table cutting is arranged at the top of a rack, the rear end of the rack is rotatably connected to the base so that the front end of the rack can swing up and down relative to the base, and therefore the compound saw can be switched between a beveling mode and a table cutting mode. Through relative positioning of the saw blade and the machine frame, the edge parts, capable of being cut, of the upper side and the lower side of the saw blade are correspondingly exposed out of the top and the bottom of the machine frame respectively, in the cutting mode switching process of the compound saw, the saw blade and the machine frame do not move relatively any more, and therefore complex driving or locking or unlocking is avoided; meanwhile, only the upper protective cover and the lower protective cover need to be controlled, so that one of the upper side and the lower side of the saw blade is in
