[0050] The specific implementation process is as follows:

[0051] Embodiment 1, the position of the nursing bed is conveniently moved by rollers. In specific implementation, the rollers can be brake universal wheels to facilitate the movement or fixation of the nursing bed. After the position of the nursing bed is fixed, the user lies on the nursing bed, with the user's legs placed on the placement plate 46 and the back placed on the upper side of multiple support blocks 11. Part of the support blocks 11 are squeezed by the user's back, and the piston is made to slide in the fixed cylinder 9 through the sliding rod 10, so that the hydraulic oil in part of the fixed cylinder 9 (that is, the fixed cylinder 9 on the lower side of the support block 11 squeezed by the user's body) is squeezed, and the hydraulic oil is made to flow in different converging cylinders 8 through the connecting pipe 12, so that the piston is squeezed inside the fixed cylinder 9 on the lower side of the support block 11 not squeezed by the user's body, and the sliding rod 10 is pushed, so that the fixed block not squeezed by the user's body rises, so that the support block 11 squeezed by the user's body always fits the user, and the support block 11 not squeezed by the user's body moves up to limit the user's body, and at the same time, the elastic rope 42 is used to make the support block 11 rotate with the body shape of the user;

[0052] Among them, different push switches 14 on each telescopic component 6 are used by the controller to control the extension and retraction of all electric push rods 13 on the corresponding single telescopic component 6. When any sliding rod 10 moves downward and any first push switch 14 on any telescopic component 6 is squeezed by the first squeezing plate 15, the generated electrical signal is transmitted to the controller, and the controller automatically controls all electric push rods 13 on the corresponding telescopic component 6 to be pushed out, so that the rubber sleeve 17 moves up to a fixed position to close the lower end of the tube body 18, so that the hydraulic oil in the corresponding fixed cylinder 9 does not flow, and then the position of the corresponding sliding rod 10 is fixed by the piston, so that the vertical position of the support block 11 on the row of the current corresponding telescopic component 6 is fixed. After the support blocks 11 on all the telescopic components 6 are fixed, the user's back is adaptively fitted and fixed, so that the support blocks 11 are prevented from shaking during massage, thereby improving the massage effect. The support blocks 11 that are not squeezed by the user move up to limit the user's sideways position, thereby improving the stability of the user's body fixation.

[0053] After the user's body is fixed, the massage operation begins. The drive motor 40 is turned on to drive the reciprocating screw 38 to rotate, and then the sliding plate 25 reciprocates horizontally. Figure 4As shown, the push rods 27 are arranged obliquely, and the push cylinders 26 are arranged in a "one" shape. In the initial state, one of the sliding columns 33 and one of the limiting rods 45 are against each other, so that the push cylinder 26 is limited, and the first permanent magnet 36 and one of the second permanent magnets 37 are attracted to each other for limiting. In the figure, when the sliding plate 25 slides, it first moves toward the direction of the drive motor 40. At this time, all the push cylinders 26 are oriented toward the push rods 27, and all the push rods 27 are oriented toward the push cylinder 26. As the sliding plate 25 moves toward the direction of the drive motor 40, different The push cylinder 26 pushes the push rod 27 in sequence according to the arrangement order of the telescopic components 6 and the push rod 27, so that the push rod 27 is inserted into the push cylinder 26, and then the first frame 7 corresponding to the corresponding telescopic component 6 is moved up, and the convergence cylinder 8, the fixed cylinder 9, and the sliding rod 10 are sequentially cooperated to drive the support block 11 to move up, so as to squeeze and massage the user's back. At the same time, the convergence cylinder 8 cooperates with the sliding column 23, the sliding column 23, the rotating tube 30, and the bearing to rotate on the outside of one end of the incomplete gear 29. As the sliding plate 25 moves toward the driving motor The first permanent magnet 36 and the second permanent magnet 37 are attracted to each other, so that the push rod 27 is limited. Then, the sliding plate 25 moves to the maximum position in the direction of the driving motor 40 (that is, when the last push cylinder 26 and the last push rod 27 are separated), and the second sliding column 33 and one of the limit rods 45 are against each other, and at the same time, the first permanent magnet 36 and one of the second permanent magnets ... The movable plate 25 slides away from the driving motor 40, and then the multiple pushing rods 27 are pushed in sequence again through the multiple pushing cylinders 26, so that the support blocks 11 of different telescopic components 6 are lifted and lowered again in sequence, thereby realizing a reciprocating massage effect on the user's back. In addition, by adjusting the distance between the first frames 7, the length of the pushing rods 27, etc., when one of the pushing cylinders 26 pushes the pushing rod 27 but has not yet separated, the next pushing cylinder 26 starts to push the corresponding pushing rod 27, thereby realizing a wave-like pushing of the first frame 7 to reciprocate and rise and fall.

[0054] In Example 2, when the pushing cylinder 26 pushes the pushing rod 27, the sliding plate 25 connected to the rod body 32 rises and falls back and forth on the gear teeth on the incomplete gear 29, and at the same time, the sliding column 33 slides and limits on the rod body 32. The above scheme realizes the shaking effect of the floating plate 31 on the incomplete gear 29, and then cooperates with the shaking effect of the rod body 32 and the converging cylinder 8 on the pushing rod 27, and realizes the shaking of the support block 11 driven by the first frame 7, the converging cylinder 8, the fixed cylinder 9, and the sliding rod 10 to push the user's back, thereby improving the massage effect through vibration.
