As a modification of the present invention, it also comprises fixing handle on the bracket, and this handle is provided with the starting switch controlling described motor.Be convenient to like this move cutting machine exactly, change handle in prior art and be arranged on motor, reduce motor oscillating to the impact promoting cutting machine.
In order to promote a kind of circular knife cutting machine like a cork, described handle becomes the angle of 0 ° to 60 ° with described chassis.
As a modification of the present invention, described handle is fixed with the motor gear switch controlling described motor.
Conveniently change circular knife, as a modification of the present invention, described rotating shaft is fixed with blade holder, described circular knife is removably fixed on this blade holder.
As the further improvement of technique scheme, described blade holder is the column structure with large footpath section and path section, and the part that this large footpath section is greater than path section forms locating surface, and this path section is formed with screw thread; The blade hold-down nut be screwed onto in this path section makes the described circular knife be fastened in path section be close to this locating surface, thus this circular knife of axial restraint.
In order to better setting circle blade, the locating surface of described blade holder is provided with elastic cylindrical pin, and described circular knife is provided with the locating hole corresponding to this elastic cylindrical pin, and this elastic cylindrical pin stretches into this described circular knife in locating hole circumference location.
As the further improvement of technique scheme, described blade holder is fixedly connected in described rotating shaft by key, and the axle head of this rotating shaft is bolted with the blade bearing hold-down screw of axial location blade holder.
As the further improvement of technique scheme, described support is fixed with the described circular knife protective cover of protection.
As the further improvement of technique scheme, described motor is non-brush permanent-magnet DC motor.
