The rotary telescoping mechanism 2 further comprises a guide assembly 43 and a connecting assembly 44; the guide assembly 43 is arranged between the second magnetic guide shell 32 and the output shaft 41 and is used for guiding the output shaft 41 to stretch and rotate; one end of the connecting assembly 44 is fastened to the mover 33, and the other end of the connecting assembly 44 passes through the second magnetically conductive shell 32 and then is fastened to the output shaft 41. When the mover 33 moves between the first magnetic conductive shell 31 and the second magnetic conductive shell 32, the output shaft 41 is driven to perform telescopic motion (i.e., move along the Z axis) through the connecting assembly 44; when the second driving assembly 20 drives the second magnetic conductive shell 32 to rotate, the second magnetic conductive shell 32 drives the output shaft 41 to rotate through the connecting assembly 44.

The guide assembly 43 can guide the output shaft 41 to move telescopically relative to the second magnetic conduction shell 32, and meanwhile, the guide assembly 43 can also keep the output shaft 41 and the second magnetic conduction shell 32 to rotate synchronously, so that the output shaft 41 is supported, friction between the connecting assembly 44 and the second magnetic conduction shell 32 when the second magnetic conduction shell 32 rotates is reduced, and the control precision of the output shaft 41 is improved.

The flange can reduce the gap between the first magnetic conductive shell 31 and the second magnetic conductive shell 32, so that the polarity of the first surface of the magnetic member 34 can be transmitted to the second magnetic conductive shell 32 through the first magnetic conductive shell 31, thereby forming a magnetic field between the second surface of the magnetic member 34 and the surface of the second magnetic conductive shell 32, and ensuring that the mover 33 makes reciprocating linear movement between the magnetic member 34 and the second magnetic conductive shell 32. Meanwhile, the flange can also play a limiting role to limit the moving range of the mover 33. The gap of 0.1-1 mm is adopted, so that smooth conduction of a magnetic field between the first magnetic conduction shell 31 and the second magnetic conduction shell 32 can be ensured, sufficient gap can be provided for rotation of the second magnetic conduction shell 32, friction between the second magnetic conduction shell 32 and the first magnetic conduction shell 31 is prevented, and interference of the first magnetic conduction shell 31 on rotation of the second magnetic conduction shell 32 is prevented.

The hollow transmission shaft 42 is fixedly inserted into the second magnetic guiding shell 32, the hollow transmission shaft 42 is rotatably connected with the first magnetic guiding shell 31, and the output shaft 41 is inserted into the hollow transmission shaft 42. The hollow transmission shaft 42 can support the second magnetic conductive shell 32, prevent the second magnetic conductive shell 32 from contacting with the first magnetic conductive shell 31 to generate friction, and is beneficial to improving the control precision of the rotation of the output shaft 41. Meanwhile, the hollow transmission shaft 41 is fixed to the second magnetic conductive shell 32, which is beneficial to reducing the impact of the hollow transmission shaft 41 or the second magnetic conductive shell 32 on the connecting assembly 44 during rotation.
Specifically, two bearings 35 are sleeved at two ends of the hollow transmission shaft 42, and two ends of the first magnetic guide shell 31 are sleeved on the two bearings 35, so that the frictional resistance of the hollow transmission shaft 42 during rotation is reduced, and the hollow transmission shaft 42 is supported.

By engaging the first guide rail 431 and the second guide rail 432, the rotation of the hollow transmission shaft 42 can be transmitted to the output shaft 41 through the first guide rail 431 and the second guide rail 432, and the output shaft 41 and the hollow transmission shaft 42 can rotate synchronously. Meanwhile, the guide rail set is adopted, so that the output shaft 41 is prevented from directly contacting the hollow transmission shaft 42, the resistance of the telescopic motion of the output shaft 41 is reduced, the load of the connecting assembly 44 is reduced, the connecting assembly 44 is prevented from being abraded, and the precision of the telescopic motion of the output shaft 41 is improved.
Further, the guide assembly 43 includes two rail sets disposed on opposite sides of the output shaft 41. By adopting the two guide rail groups which are oppositely arranged, the output shaft 41 can be well supported, the gravity centers of the two guide rail groups can fall on the rotating axis of the output shaft 41, and the output shaft 41 is prevented from eccentric motion.

The avoidance groove 320 is adopted to avoid the connecting block 441, on one hand, the connecting block 441 transmits the movement of the mover 33 along the Z axis to each output shaft 41 to enable the output shafts 41 to stretch and retract, and on the other hand, the connecting block 441 is in clearance fit with the second magnetic guide shell 32, so that friction between the connecting block 441 and the inner wall of the avoidance groove 320 is avoided, and interference of the inner wall of the avoidance groove 320 on the movement of the connecting block 441 is prevented.

Not only can the friction generated between the mover 33 and the second magnetic conduction shell 32 and the first magnetic conduction shell 31 be avoided, but also the friction generated by the direct contact between the output shaft 41 and the second magnetic conduction shell 32 can be avoided, and further the control precision of the extension and retraction and rotation motion of the output shaft 41 is improved. Preferably, a gap is formed between the second magnetic conduction shell 32 and the output shaft 41, so that the second magnetic conduction shell 32 can be prevented from directly contacting with the output shaft 41, the resistance of the movement of the output shaft 41 is reduced, and the control precision of the telescopic movement of the output shaft 41 is improved.
