Abstract: A handle and motor housing structure of a circular sawing machine includes a hollow motor housing having a front side integrally formed with a handle lower casing plate. A handle upper casing plate is secured on the handle lower casing plate, such that the handle upper casing plate may be integrally screwed with the handle lower casing plate which is integrally formed with the front side of the hollow motor housing. Thus, the motor housing is integrally formed with the handle lower casing plate to form a modularized structure, thereby efficiently enhancing the assembly efficiency of the motor coil circuit and the press switch, and thereby further increasing the stability and rigidity of the press operation of the circular sawing machine.
