Embodiment 1
[0035] The B-type mechanism that can lift and swing the massage head, see figure 1 , figure 2 , this mechanism is provided with a guide seat 6 with a transverse notch, the motor mounting seat 5 is arranged in the said transverse recess of the guide seat, and a coaxial vertical hole is opened on the guide seat 6 and the motor mounting seat 5, and the vertical hole A guide tube 2 is inserted in the center, the guide tube is loosely sleeved on the vertical hole of the guide seat 6, and the guide tube is tightly sleeved and fixed on the vertical hole of the motor mounting seat 5, and a swing rod 7 is arranged inside the guide tube 2. The middle part of the swing rod is radially connected with a swing rod pin 8, and the two ends of the swing rod pin are pivotally connected to the radially corresponding pipe wall position of the guide tube 2, and the outer diameter of the swing rod is smaller than the inner diameter of the guide tube (or the swing rod is upward from the swing rod p...
Embodiment 2
[0038] This example is different from the previous example in that the middle part of the swing rod is connected with a ball joint 12, replacing the swing rod pin 8, and the outer wall of the ball joint is connected with the inner wall of the guide tube, see image 3 . The middle part of the swing rod 7 supports the ball joint, which can realize the swing of the swing rod in any direction.
Embodiment 3
[0040] In this example, on the basis of Example 1 or Example 2, a slide block 14 is connected to the guide seat, and the slide block is equipped with a vertical slide rail 13, and the vertical slide rail is connected with a traversing plate 3, and the traversing plate 3 and the guide seat 6 is provided with a lifting device that cooperates with each other, that is: a screw motor 15 is installed on the traversing plate, the guide seat 6 is connected with a screw frame 601, the output shaft of the screw motor is equipped with a screw 17, and the screw nut 16 of the screw The nut frame 601 connected to the guide seat; see Figure 4 .
[0041] The screw motor 15 runs, and the screw rod 17 drives the screw nut 16 together with the screw nut frame 601, the guide seat 6, the motor mounting seat 5, the motor A4, the guide tube 2, the swing rod 7 and the massage head 1 according to the vertical slide rail 13 moves to realize the adjustment of the up and down position of the massage he...
