A miter saw. The saw includes a base on which a scale disk is connected and a bench is rotatably connected on the disk. An angle position device is connected to the bench. Notches are defined in an underside of the scale disk and the angle position device is engaged with one of the notches. A position member is movably connected to the body of the angle position device and a lever is connected to the position member which is pushed to contact a periphery of the scale disk to position the scale disk. A connection member is connected to the bench and a circuit saw assembly is pivotally connected to the connection member. A handle on the circular saw assembly can be pulled out and rotated to adjust an angle thereof.

What is claimed is: 1. A miter saw comprising: a base and a scale disk connected on said base, a bench rotatably connected on said disk and a plurality of notches defined in an underside of said scale disk, an angle position device connected to said bench and having a tongue engaged with one of said notches, a lever pivotally connected to a body of said angle position device and an eccentric portion extending from an end of said lever, a mediate member pivotally connected to said eccentric portion, a support member connected to said body of said angle position device and a position rod movably extending through said support member, an end of said position rod pivotally connected to said mediate member and the other end of said position rod contacting a periphery of said scale disk when said lever is pivoted to push said position rod, and a connection member connected to said bench and a circular saw assembly pivotally connected to said connection member. 2. The miter saw as claimed in claim 1 further comprising a position member movably extending through said body of said angle position device, said tongue connected to said position member, said tongue being lowered to disengage from one of said notches when pushing said position member. 3. A miter saw comprising: a base and a scale disk connected on said base, a bench rotatably connected on said disk and an angle position device connected to said bench; a connection member connected to said bench and a circular saw assembly pivotally connected to said connection member, said circular saw assembly having a handle pivotably connected thereto; said circular saw assembly has a block to which said handle is pivotally connected, a first connection port located on an end of said block and a recessed area defined in a surface of said first connection port, a first central hole defined through an inside of said recessed area and a plurality of concavities defined in said inside of said recessed area; said handle having a second connection pot port which has a protrusion extending from a first surface thereof, said protrusion removably engaged with said recessed area and a second central hole defined through said protrusion and said second connection port, a plurality of rods extending from said protrusion and engaged with said concavities, the number of said concavities being more than the number of said rods, a seat member connected to a second surface of said second connection port and a passage defined through said seat member, a flange extending from a periphery defining said passage, said passage communicating with said second central hole; a pin extending through said passage, said second central hole and said first central hole, a clamp connected to an end of said pin to prevent said pin from dropping from said first central hole, a spring mounted to said pin and biased between said flange and a head of said pin, a thread hole defined in said head of said pin and said head of said pin being sized to be movably received in said passage; and a locking member having an eccentric hole defined therethrough and a bolt extending through said eccentric hole and engaged with said thread hole, said locking member freely rotated about said bolt, a section extending from said locking member and said eccentric hole defined through said section which is sized to be inserted in said passage. 4. The miter saw as claimed in claim 3 further comprising a groove defined in said surface of said first connection port and a position tube extending from said first surface of said second connection port, said position tube movably received in said groove. 5. The miter saw as claimed in claim 3 further comprising an eccentric convex surface extending from a distal end of said section and said eccentric convex surface contact said head of said bolt. 6. A miter saw comprising: a base, and a bench rotatably connected to said base; a saw assembly having an arm pivotally connected to said bench and a saw attached to the arm; a handle assembly connected to the saw assembly and having a handle axially moveable between a first position allowing handle rotation and a second position preventing handle rotation; and a locking mechanism cooperative with the handle assembly and saw assembly, said locking mechanism having a biasing member for biasing the handle towards the second position, wherein when engaged the locking mechanism maintains the handle at the second position and prevents axial movement of the handle towards the first position, whereby the handle is fixed at a selected rotational orientation of the handle relative to the saw assembly during a cutting operation of the saw; wherein: the handle assembly further comprises: a block attached to the saw assembly, a first connection port located on an end of said block and a recessed area defined in a surface of said first connection port, a first central hole defined through an inside of said recessed area and a plurality of concavities defined in said inside of said recessed area; a second connection port on the handle which has a protrusion extending from a first surface thereof, said protrusion removably engaged with said recessed area and a second central hole defined through said protrusion and said second connection port, a plurality of rods extending from said protrusion and engaged with said concavities, a seat member connected to a second surface of said second connection port and a passage defined through said seat member, a flange extending from a periphery defining said passage, said passage communicating with said second central hole; and a pin extending through said passage, said second central hole and said first central hole, a clamp connected to an end of said pin to prevent said pin from dropping from said first central hole; the biasing member comprises a spring mounted to said pin and biased between said flange and a head of said pin, a thread hole defined in said head of said pin and said head of said pin being sized to be movably received in said passage; and the locking mechanism further comprises a locking member having an eccentric hole defined therethrough and a bolt extending through said eccentric hole and engaged with said thread hole, said locking member freely rotated about said bolt, a section extending from said locking member and said eccentric hole defined through said section which is sized to be inserted in said passage.
