[0038] When the transmission shaft 20 rotates, under the guidance of the spiral guide groove 31, the telescopic rotating cylinder 30 moves along the guide member 12 to form a transmission mechanism that can reciprocate, telescope and rotate.

[0039] like Figure 2 As shown, the telescopic rotating mechanism includes a mounting seat 10, a transmission shaft 20 and a telescopic rotating cylinder 30. Among them, the mounting seat 10 is a component used to be installed inside the massager, and is used to accommodate the telescopic rotating cylinder 30 and the transmission shaft 20. A fixed guide member 12 is also provided on the mounting seat 10. The transmission shaft 20 is used to connect the actuator 40 of the massager, and is driven by the actuator 40 to rotate along its own axis. A spiral guide groove 31 is provided on the outer surface of the telescopic rotating cylinder 30. The telescopic rotating cylinder 30 is movably sleeved on the transmission shaft 20, and is driven to rotate by the transmission shaft 20. The telescopic rotating cylinder 30 rotates coaxially with the transmission shaft 20.

[0040] The innovation of the present invention is that when the transmission shaft 20 rotates to drive the telescopic sleeve to rotate, the spiral guide groove 31 and the guide member 12 interact with each other to make the telescopic rotating cylinder 30 move along the guide member 12 in the mounting seat 10, and the telescopic rotating cylinder 30 rotates while performing a reciprocating telescopic action, thereby forming a transmission mechanism that can reciprocate, telescope and rotate. Specifically, the specific structure provided by the present invention is used for explanation.

The guide member 12 is adapted to be inserted in the spiral guide groove 31. When the transmission shaft 20 rotates to drive the telescopic sleeve to rotate, under the guidance of the spiral guide groove 31, the telescopic rotating cylinder 30 moves along the guide member 12 to form a transmission mechanism that can reciprocate, telescope and rotate.

[0047] One end of the telescopic rotating cylinder 30 is used to movably cover the transmission shaft 20, and the other closed end of the telescopic rotating cylinder 30 is used to be fixedly connected to the massage component 50 to drive the massage component 50 to telescope and rotate.
