[0002] Currently, with social progress and the rapid development of human civilization, the pace of work and life is constantly accelerating. People from all walks of life are busy striving for a better life, leaving little time for physical exercise. As a result, people's health is declining, especially among office workers who spend long hours in front of computers and drivers who sit for extended periods. These individuals suffer from severe muscle strain in the neck and shoulders, poor blood circulation, and are prone to conditions such as frozen shoulder and cervical spondylosis. To address this, a massage device has emerged. This device's massage mechanism includes a first massage mechanism, a second massage mechanism, and a drive mechanism to drive these mechanisms. It can perform kneading massage on the neck and shoulders and tapping massage on the back and shoulders, thereby relaxing the neck and shoulder muscles and relieving neck and shoulder pain. The drive mechanism of this massage mechanism includes a motor and a transmission shaft. The motor's output shaft is connected to the first massage mechanism via a first transmission component, and the second transmission component is connected to the transmission shaft, which in turn drives the second massage mechanism to perform tapping massage. However, the drive mechanism of this massager requires multiple sets of transmission components and a drive shaft, resulting in a complex overall structure and high cost. Utility Model Content

[0035] This utility model discloses a massage mechanism in which, during operation, the motor 2 starts, driving the worm gear 21 to rotate, which in turn drives the first gear 52 to rotate via the worm wheel 51 and the second gear 53. The first gear 52 then drives the eccentric component 32 to rotate, causing the swing sleeve 31 to swing left and right, thus enabling the second massage head 33 to perform kneading massage. At the same time, the eccentric component 32 drives the transmission arm 8 to swing left and right at a small angle, which in turn drives the swing arm 41 to swing left and right at a small angle via the connecting rod 9. The eccentric wheel 6 then drives the swing arm 41 to swing back and forth, enabling the first massage head 42 to achieve a wide range of tapping function, thereby increasing the range and rhythm of the tapping massage and enhancing the massage experience.
[0036] Therefore, this utility model can realize the tapping massage function of the second massage mechanism 4 without the need for additional drive shaft and transmission components between the drive shaft and the motor, resulting in fewer overall parts, a more compact rhythm, and lower cost.
