This embodiment is another modified scheme based on embodiment 4, and the main structure thereof is the same as embodiment 4, and the improvement point is that: as shown in fig. 6, 7 and 8, the bottom end of the second moving rod 302 is hinged to the neck support mechanism 2, so that the neck support mechanism 2 synchronously drives the head supporting plate 301 to descend during the lifting process, and synchronously drives the head supporting plate 301 to ascend during the descending process of the neck support mechanism 2; the neck support mechanism 2 comprises a neck support plate 201 and support rod groups symmetrically arranged on two sides of the neck support plate 201, each support rod group comprises a first positioning rod 202 and a first moving rod 203, the surfaces of the first positioning rod 202, the first moving rod 203, the neck support plate 201 and the support frame plate 1 form a four-bar linkage mechanism, the bottom of the first moving rod 203 is located in a track groove 404, and a cam mechanism 4 arranged in the support frame plate 1 drives the first moving rod to move in the track groove 401 to adjust the distance between the first positioning rod 202 and the first positioning rod 203, so that the neck support plate 201 is lifted, the bottom end of the second moving rod 302 is hinged to the lower portion of the first moving rod 203, and the second moving rod 302 is driven to move simultaneously when the first moving rod 203 reciprocates.

Example 7

This embodiment is another modified scheme based on embodiment 4, and the main structure thereof is the same as embodiment 4, and the improvement point is that: as shown in fig. 6, 7 and 8, the swing support plate 304 has two grooves perpendicular to the swing direction of the swing mechanism 5, each groove is slidably provided with a positioning block 306, the bottom ends of the second positioning rods 303 in the two sets of support assemblies are respectively rotatably connected with the tops of the two positioning blocks 306, each positioning block 306 is provided with a limiting block 305, and the limiting block 305 and the second moving rod 302 are respectively located at opposite sides of the second positioning rods 303 to prevent the head supporting plate 301 from falling down.

In this embodiment, as shown in fig. 6, the second moving rod 302 is located between the second positioning rod 303 and the neck support mechanism 2, and the limiting block 305 is vertically disposed and adjacent to the second positioning rod 303; the limiting block 305 is fixed at any position of the groove through a screw, when the height of the head supporting plate 301 needs to be adjusted, the screw is screwed out, the limiting block 305 is moved to a suitable position in the groove and then is screwed and fixed through the screw, the screw is fixed, and how the limiting block 305 moves in the groove is not shown in the figure.

Example 8

The present embodiment is another modified scheme based on embodiment 1, and the main structure of the present embodiment is the same as that of embodiment 1, and the improvement point is that: as shown in fig. 3, the support frame plate 1 is a plate-shaped member, an upper bearing portion 105 and a lower bearing portion 106 are respectively disposed on an upper surface and a lower surface of one end of the support frame plate, and an end of the lower bearing portion 106 extends beyond an end of the upper bearing portion 105, so as to form a bearing platform 103 for supporting the head support mechanism 3, and a horizontal cavity 102 which is communicated with the bearing platform 103 and accommodates the swing mechanism 5 is formed between the upper bearing portion 105 and the lower bearing portion 106; the upper bearing part 105 has a transmission chamber 101 therein, and the transmission chamber 101 has a cam mechanism 4 therein for providing a periodical lifting power to the neck support mechanism 2.

Example 9

The embodiment is an improved scheme based on the embodiment 8, and the main structure of the embodiment is the same as that of the embodiment 8, and the improvement point is that: as shown in fig. 3, the lower bearing portion 106 has a power cavity 104 therein, the power cavity 104 has a driving assembly 6 therein, the driving assembly 6 includes a driving motor and a multi-stage reducer, the multi-stage reducer has two power output ends with different rotation speeds, one power output end with a high rotation speed drives the swing mechanism 5, and one power output end with a low rotation speed drives the cam mechanism 4 to drive the neck support mechanism 2 to periodically lift.

In this embodiment, the connection mode and the control mode of the power assembly 6 are known by those skilled in the art, and are not described herein, it should be noted that the control and adjustment of the power assembly 6 can be preferably designed into a control board, the control board is led out by a lead wire, so that a user can conveniently grasp and use the adjustment by himself or herself, buttons are provided on the control board, and the user can realize the autonomous adjustment and start and stop by the buttons with different functions.
