It is connected to body rear end, lighting device is equipped with above body, handle front is equipped with control switch and light switch, control is equipped in handle
Circuit board processed, control circuit board are clamped with body, and handle base is equipped with supply unit, lighting device and control circuit board and illumination
Electrical connection is switched, motor is electrically connected with control circuit board and control switch, and supply unit is switched respectively with control and light switch
Electrical connection.
Specifically, heat radiation rack includes blinds and thermovent, blinds is the trapezoidal shape of interior narrow outer width, and blinds is fixed on heat dissipation
In frame, thermovent is uniformly distributed between blinds.
Beneficial effects of the present invention：Reasonable design of the present invention, can by control switch connection radiator active heat removal,
So that the motor of electric hammer is radiated always in working condition, will not overheat, to protect motor, improves the working efficiency of electric hammer, prolong
The service life of long electric hammer, meanwhile, the present invention is equipped with lighting device, can equally work under dim environment.
