Rotary telescopic massager

A rotary telescopic massager, comprising:

• a cylindrical shell comprising a first cylindrical housing and a second cylindrical housing, wherein a port of the first cylindrical housing is detachably joined to a port of the second cylindrical housing, a rotary telescopic apparatus is installed in an inner chamber of the first cylindrical housing and comprises a first installation bracket, a first motor, a rotary driver, a guide rod, a connection rod and a rotary disk, wherein a guide channel disposed in an axial direction of the cylindrical shell is formed on the first installation bracket, the rotary driver is at least partially movably disposed within the guide channel, the rotary disk is installed on a rotary shaft of the first motor, an axis of the guide rod is parallel to an axis of the rotary driver, the rotary driver is slidably connected to the guide rod, and two ends of the connection rod are rotatably connected to an outer side of the rotary driver and an eccentric portion of the rotary disk, respectively;
• and
• a massage element disposed in an inner chamber of the second cylindrical housing and comprising a cylindrical body and a flexible massage sleeve disposed within the cylindrical body, wherein a closed end of the cylindrical body is detachably connected to a rotary portion of the rotary driver, and an opening of the flexible massage sleeve is oriented in the same direction as an opening of the second cylindrical housing,
• wherein when the first cylindrical housing is detached from the second cylindrical housing, the massage element is fully exposed, such that the massage element is disconnected from a rotary output shaft of the rotary driver, thereby rendering both the massage element and the first cylindrical housing with the rotary telescopic apparatus independent of each other.
