Angle cutting machine with exchangeable cutting members

An angle cutting machine with exchangeable cutting members, comprising:

• a base portion stably rested on a flat surface;
• an adjusting device, disposed on the base portion, wherein the adjusting device comprises a base board, an adjusting portion and a position limiting portion, and wherein the base board is fixedly disposed on the base portion and an adjusting area and a position limiting area are formed in the base board, and wherein the position limiting area is in communication with the adjusting area and the adjusting portion is disposed in the adjusting area and can spin around, and wherein several exterior walls and several position limiting slots are provided on the adjusting portion and each of the exterior walls of the adjusting portion has a different inclination or arc shape and the position limiting slots are formed between each pair of the exterior walls, and wherein the position limiting slots and the exterior walls are arranged in an alternating manner, and wherein the position limiting portion is disposed in the position limiting area and can spin around and a position limiting protrusion is provided on the position limiting portion, and wherein as the position limiting protrusion enters the position limiting slot, the adjusting portion would not be able to rotate;
• a cutting device, having a vertical axle and a plurality of cutting members, wherein the vertical axle can carry out a reciprocating up-down motion and spin, and wherein the cutting members circumferentially encircle the cutting device;
• a powering device, disposed on the base portion, wherein the powering device can provide power to the vertical axle so that the vertical axle can carry out the reciprocating up-down motion;
• and
• a positioning device, wherein the positioning device moves along with the cutting device to ensure the correct positioning of the cutting device.
