Telescopic assembly and occlusion mechanism

A telescopic assembly, comprising:

• a rotating shaft, spiral orbits extending in an axis direction being disposed on the circumferential side of the rotating shaft, the spiral orbits comprising a first spiral orbit and a second spiral orbit opposite to the first spiral orbit in rotation direction, the initial end of the first spiral orbit communicating with the tail end of the second spiral orbit, and the tail end of the first spiral orbit communicating with the initial end of the second spiral orbit;
• a telescopic piece, the telescopic piece being located on one side of the rotating shaft and doing linear reciprocating movement in the axis direction;
• and
• a connecting piece, the connecting piece being located between the rotating shaft and the telescopic piece, one end of the connecting piece being movably connected to the telescopic piece, and the other end thereof being abutted with the spiral orbits;
• an occlusion mechanism, comprising a first rocking bar comprising a first connecting end and a first occluding end;
• a second rocking bar comprising a second connecting end and a second occluding end;
• wherein both of the first connecting end and the second connecting end are movably connected to the telescopic piece, and the telescopic piece does reciprocating movement in the axis direction so that the first occluding end is adjacent to or away from the second occluding end;
• then, the telescopic assembly pushes the first rocking bar and the second rocking bar to achieve an occlusion action so that an effect of simulating automatic occlusion of a mouth is achieved in the technical field of health care products.
