When necessary, the strong and weak adjustment gear rotates, and through its meshing action with the fan-shaped rack 2, the fan-shaped rack 2 and the frame 86 are driven to rotate relative to the frame 66 and around the strong and weak rotation axis 1, so as to drive the front massage head 23 and the rear massage head 45 to move in the direction of approaching and moving away from the human body, so as to adjust the massage intensity. At the same time, as Figure 2 and Figure 4 As shown, in this embodiment, a strong and weak limit member 7 is provided on the other end of the frame 86, and a first limit protrusion and a second limit protrusion are provided at both ends of the strong and weak limit member 7. The first limit protrusion and the second limit protrusion are both used to conflict with the limit part on the frame 66 to limit the rotation range of the frame 86 relative to the frame 66, thereby preventing the massage force from being too large or too small.

[0073] like Figure 1 As shown, in this embodiment, a front roller is installed on the other end of the front massage arm 26, and the front roller constitutes the front massage head 23. A rear roller is installed on the other end of the rear massage arm 30, and the rear roller constitutes the rear massage head 45.

[0075] like Figure 3 As shown, the kneading assembly 65 in this embodiment also includes a grabbing and kneading motor 15, which drives the worm gear transmission mechanism through a belt transmission mechanism, and transmits the torque to the drive shaft 58 after deceleration through the worm gear transmission mechanism. Specifically, the first pulley 11 is installed on the output shaft of the grabbing and kneading motor 15, the second pulley 13 is installed on the worm 10, the first belt 14 is sleeved on the first pulley 11 and the second pulley 13, the worm 10 is meshed with the worm wheel 6 installed on the drive shaft 58, and the worm wheel 6 adopts a helical gear.

[0076] like Figure 1 and Figure 3 As shown, in this embodiment, the knocking shaft 52 is connected to the reduction box 8, and the knocking motor 18 drives the knocking shaft 52 to rotate through the reduction box 8. The reduction box 8 is provided with a third pulley 16, a second belt 17 and a fourth pulley 19. The knocking motor 18 transmits torque to the knocking shaft 52 after deceleration through the third pulley 16, the second belt 17 and the fourth pulley 19.

[0077] In this embodiment, the front massage arm 26 and the rear massage arm 30 are both curved arms. The first connecting rod 50 and the second connecting rod 39 are both ball-end connecting rods. The first eccentric wheel 27, the front massage arm 26, the first connecting rod 50, the knocking shaft 52, and the reduction box 8 together constitute the first five-bar linkage; the second eccentric wheel 28, the rear massage arm 30, the second connecting rod 39, the knocking shaft 52, and the reduction box 8 together constitute the second five-bar linkage. In this embodiment, the front roller is mounted on the front massage ball shaft at the other end of the front massage arm 26; the rear roller is mounted on the rear massage ball shaft at the other end of the rear massage arm 30.

[0078] like Figure 1 As shown, in this embodiment, the drive shaft 58 transmits torque to the first eccentric wheel 27 and the second eccentric wheel 28 through two cylindrical pins 59. When the drive shaft 58 drives the first eccentric wheel 27 and the second eccentric wheel 28 to rotate together, the first eccentric wheel 27 drives the front massage arm 26 to swing forward and backward and in the radial direction, and the second eccentric wheel 28 drives the rear massage arm 30 to swing forward and backward and in the radial direction. In this embodiment, the side edge of the first eccentric wheel 27 farthest from the driving inclined shaft section 582 and the side edge of the second eccentric wheel 28 farthest from the driving inclined shaft section 582 are respectively located on both sides of the driving inclined shaft section 582, and are symmetrically distributed. In this way, when the first eccentric wheel 27 drives the front massage arm 26 to swing forward, the second eccentric wheel 28 drives the rear massage arm 30 to swing backward; when the first eccentric wheel 27 drives the front massage arm 26 to swing backward, the second eccentric wheel 28 drives the rear massage arm 30 to swing forward, so that the grabbing action is achieved. At the same time, due to the inclined structural design of the drive shaft 58, the front massage arm 26 and the rear massage arm 30 can achieve the kneading action, and the combination of the two can achieve the action of grasping and kneading. In addition, the knocking shaft 52 is based on the eccentric structural design of its shaft end, and the front massage arm 26 and the rear massage arm 30 are driven by the first connecting rod 50 and the second connecting rod 39 to respectively achieve the action of knocking, shaking or knocking. The knocking and grasping and kneading functions are combined together to achieve the effect of grasping and kneading while shaking. The strength adjustment gear of the strong and weak driving component 72 drives the fan-shaped rack 2, driving the kneading and knocking component 65 to rotate up and down around the strong and weak rotating shaft 1 to achieve the strong and weak changes in the massage force. In summary, the three functions of grasping and kneading, shaking and up and down strength are used together to achieve the effect of imitating the grasping, kneading and pinching massage of human hands.
