Abstract: A power-controlled sawing machine provided with a clamping and angle-adjusting mechanism and a safety alignment mechanism. The clamping and angle-adjusting mechanism consists of first and second clamping plates to clamp an object to be cut therebetween. The second clamping plate further effects the adjustment of the angular position of the second clamping plate relative to the sawing direction. The safety alignment mechanism includes a stop plate which can be moved and turned to align with the second clamping plate so as to prevent a cut piece from bouncing out and injuring people.

Abstract: An anti-sway device for a saw web mounted on a cutting machine, comprises a pin shaft, a pin sleeve, two nuts, a compression spring, a bronze pressing member, and a bolt. The pin shaft has an internally threaded bore formed at one end for the bolt to thread there into. The pin sleeve has external threads to engage with the two nuts so that the pin sleeve can be fixed to a protective housing of the cutting machine by the nuts, The pin sleeve further has a spring cavity to contain the compression spring therein, By means of the bolt, the bronze pressing member is screwed to the pin shaft and contacts the compression spring while the latter always pushes the bronze pressing member against the saw web to prevent the same from swaying during the cutting operation.
