[0031] A coaxially arranged second worm gear 27 and a second transmission gear 28 are provided between the mobile output gear 24 and the worm 221 at the corresponding end. The second worm gear 27 is meshed with the worm 221 , and the second transmission gear 28 is meshed with the mobile output gear 24 .

[0032] The transmission between the first worm gear 25 and the first transmission gear 26, and between the second worm gear 27 and the second transmission gear 28 are both carried out through one-way bearings;

[0033] The massage head 3 is arranged on the surface of the housing 21, and the end surface of the massage output gear 23 is transmission-connected to the massage head 3;

[0034] The end surface of the movable output gear 24 is in transmission connection with the chassis 1 , and is used to drive the housing 21 to slide on the chassis 1 .

[0035] Through the above scheme, the utility model uses the worm 221 at both ends of the dual-axis motor 22 to drive the massage output gear 23 and the mobile output gear 24 respectively, so that a single motor can provide power for the sliding of the shell 21 and the massage action of the massage head 3, thereby achieving the purpose of simplifying the internal structure of the massage device, reducing costs, and making the product lighter and more convenient to use; the first worm gear 25 and the first transmission gear 26, the second worm gear 27 and the second transmission gear 28 respectively play a transmission role between the worm 221 and the massage output gear 23 and the mobile output gear 24, and the one-way bearing can satisfy the requirement that power can be transmitted to the corresponding gear only when the worm 221 rotates in one direction of forward or reverse, thereby realizing the corresponding action, so that the various functions do not interfere with each other and operate stably.

[0036] Specific embodiments of the present invention are shown below.

[0037] The housing 21 includes a detachably connected upper cover 21a and a lower cover 21b to facilitate installation of internal components.

The housing 21 is provided with a wing 211 on its side that slides onto the guide rod 11. A first roller 29 is provided on the end face of the movable output gear 24. The axis of the first roller 29 does not overlap with the axis of the movable output gear 24, so that when the movable output gear 24 rotates, the first roller 29 performs a circular motion around the axis of the movable output gear 24. The first roller 29 is movably engaged within the first movable groove 12. Through the cooperation between the wing 211 and the guide rod 11, and the first roller 29 and the first movable groove 12, when the movable output gear 24 rotates, the housing 21 reciprocates on the chassis 1. In this embodiment, guide rods 11 are provided on both sides of the chassis 1, and wing 211 is provided on both sides of the housing 21.

[0039] Furthermore, the housing 21 is provided with a first clearance hole 212 opposite to the movable output gear 24 .

The axis of the third roller 220 does not overlap with the axis of the massage output gear 23, allowing the third roller 220 to perform a circular motion around the axis of the massage output gear 23 when the massage output gear 23 rotates. A second movable groove 31 and a movable hole 32 are provided at each end of the massage head 3. The second roller 210 flexibly fits within the second movable groove 31, while the third roller 220 rotatably fits within the movable hole 32, acting as a bearing. The cooperation between the second roller 210 and the second movable groove 31, and the third roller 220 and the movable hole 32, enables the massage head 3 to perform a pinching and kneading action when the massage output gear 23 rotates.

[0041] Furthermore, the housing 21 is provided with a second paving hole 213 opposite to the massage output gear 23 .

[0042] The driving device 2 further includes a circuit board 230 and a power supply 240 installed in the housing 21 , which are respectively used to control the dual-axis motor 22 and supply power to the dual-axis motor 22 to achieve automation.
