As an improvement: the periphery of the first magnetic part at the two ends of the driving frame is provided with an isolation structure.

The utility model provides a beneficial effect is: adopt reverse effort drive frame in turn, the motor for drive the platform face of drive frame below rotatory can, need not eccentric structure, no eccentric loss promptly, for rotatory direct drive to the motor, the power mode of magnetomotive promotes the science and technology greatly and feels, and the directionless conversion is not influenced by tool bit face load pressure, and motor current changes for a short time, is the straight line basically. Because the acting force is magnetic force, namely the magnetic suspension arrangement is adopted between the two ends of the driving frame and the rotating platform, the magnitude and the frequency of the acting force can be adjusted through the magnetic strength of the acting sheet and the first magnetic part and the number of the acting positions, the adjusting domain is large, and the driving mode that reciprocating type eccentric driving can be realized is broken through. Meanwhile, the driving frame only needs to be coaxial above the rotating platform, and the horizontal plane is not limited by a connecting angle, so that the driving frame can be rotatably inserted and connected and installed in 360 degrees, and the whole machine, particularly the cutter head, has higher degree of freedom and flexibility.

The present invention will be described in further detail with reference to the accompanying drawings and examples.
