[0018] As shown in the drawing, Figure 1 The high-speed rotating high-frequency reciprocating movement mechanism in the embodiment includes: a rack 1, a reciprocating drive mechanism, a high-speed rotating motor 7 and a magnetic coupling rotating drive mechanism 8 arranged on the rack 1. The high-speed rotating motor 7 is connected with the outer rotor 81 of the magnetic coupling rotating drive mechanism 8 to drive the outer rotor 81 to rotate at high speed, and the rotating shaft of the inner rotor 82 of the magnetic coupling rotating drive mechanism 8 is arranged on the reciprocating drive mechanism in a rotatable manner, so that the rotating shaft of the inner rotor is driven by the reciprocating drive mechanism to reciprocate.

[0019] In this embodiment, the reciprocating drive mechanism includes a reciprocating drive motor 2, a cam 3, a connecting rod 6, a sliding block 4 and a sliding rail 5;The reciprocating drive motor 7 and the sliding rail are arranged on the rack 1, the cam 3 is arranged on the rotating shaft of the reciprocating drive motor 7, the sliding block 4 is arranged on the sliding rail 5 in a slidable manner, and the two ends of the connecting rod 6 are respectively hinged with the cam 3 and the sliding block 4.

The cam 3 is driven to rotate by the reciprocating drive motor 2, so that the sliding block 5 is driven to reciprocate along the sliding rail 4 through the connecting rod 6.

[0020] Further, the magnetic coupling rotating driving mechanism 8 is provided with a rotor support, an outer rotor 81 and an inner rotor 82 matched with the outer rotor 81, and a gap is arranged between the inner rotor 82 and the outer rotor 81.
