[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] Example: Figures 1-11 As shown, the telescopic massager described in this embodiment includes a massage drive unit 1 and a massage unit 2. The massage drive unit 1 can drive the massage unit 2 to perform telescopic movements, thereby enabling the massage unit 2 to perform percussion massage on acupoints.

[0021] The massage drive unit 1 includes a housing 11, a telescopic drive device 12 disposed within the cavity of the housing 11, and a telescopic member 13. The housing 11 has a linear telescopic guide channel 110. The telescopic member 13 is at least partially movably disposed within the telescopic guide channel 110. The connecting end of the massage unit 2 is detachably connected to the telescopic member 13, and the massage body of the massage unit 2 is located outside. The inner wall of the telescopic guide channel 110 and the outer wall of the telescopic member 13 are respectively provided with a guide protrusion 133 and a linear guide groove disposed along the length of the telescopic guide channel 110. The guide protrusion 133 is correspondingly placed within the linear guide groove. The telescopic drive device 12 includes a motor, a drive gear 122, a rotating member 15, and at least one driven gear. The drive gear 122 is mounted on the motor. On the main shaft, the driven gear meshes with the driving gear 122 for transmission. The rotating member 15 is mounted on the shaft of the driven gear. The driving end of the telescopic member 13 is provided with a transverse elongated hole 131. The axis of the transverse elongated hole 131 is perpendicular to the axis of the telescopic member 13. The eccentric part 151 of the rotating member 15 is movably placed in the transverse elongated hole 131. The motor drives the driving gear 122 to rotate, which in turn drives the driven gear to rotate, thereby driving the rotating member 15 to rotate. Under the action of the eccentric part 151 rotating around the shaft of the driven gear, it pushes and pulls, causing the telescopic member 13 to make linear reciprocating motion in the telescopic guide channel 110. This causes the power output by the motor to be decelerated by the gear transmission and then output, thereby reducing the speed and telescopic frequency of the rotating member 15 and the telescopic member 13.

[0022] Preferably, the number of driven gears is set to multiple, and the multiple driven gears mesh with each other. The driven gear at the transmission start end of the multiple driven gears meshes with the driving gear 122, and the rotating member 15 is installed on the shaft of the driven gear at its transmission output end. Among them, the first stage driven gear 123 is a stepped gear. The large gear of the stepped gear meshes with the driving gear 122, the small gear of the stepped gear meshes with the second stage driven gear 124, and the second stage driven gear 124 meshes with the third stage driven gear 125. Therefore, the rotating member 15 is fixedly installed on the shaft of the third stage driven gear 125. The diameters of the large gear of the first stage driven gear 123, the second stage driven gear 124, and the third stage driven gear 125 are larger than the driving gear 122, and the diameter of the large gear of the first stage driven gear 123 is equal to the diameter of the driving gear 122.

The soft sleeve 3 is generally made of silicone material, and the deformable length of the deformable part 31 is adapted to the telescopic stroke of the telescopic member 13 to avoid pulling the connection of the port of the deformable part 31.

The sleeve clamp 8 abuts against the inner side of the ring body 311, and the end face of the deformable part 31 also abuts against the inner side of the convex ring, so as to fix the port of the deformable part 31 to the telescopic member 13. The fixing sleeve 7 and the end of the telescopic member 13 are fixed by a snap fastener. Both the telescopic member 13 and the fixing sleeve 7 are made of hard plastic, and the sleeve clamp 8 is made of metal. The above structure makes it easier to fix the port of the deformable part 31.

The insert 27 of the first column 23 passes through the perforation 26 at the end of the cylindrical elastomer 23 and is fixedly connected to the other half of the inner shell 211, so that the end of the cylindrical elastomer 23 is fixedly connected to the first column 21 and the second column 22 respectively. The two half of the inner shell 211 of the second column 22 are respectively provided with half of the inner groove 212 adapted to the second vibration motor.
