and the middle part of the bottom of the slider 4 is provided with a limiting recess 44 , which is parallel to the groove 42 receiving the ball seating 7 , having two end walls for limiting the stopping block 81 when the slider slides on the soleplate , the stopping block 81 and a sliding shaft 82 are disposed within the limiting recess 44 ; in order to prolong the service life of the stopping block 81 , the limiting recess 44 further comprises two shockproof pads 83 for pressing against the stopping block 81 , the shockproof pads 83 may eliminate the shock generated during the horizontal movement of the slider 4 to the limit end , and also reduce collision noise , each shockproof pad disposed at one end wall of the limiting recess 44 , and each shockproof pad 83 has a positioning hole 831 for receiving the sliding shaft 82 ; the stopping block 81 further comprises a damping adjustment hole 812 is formed at a bottom of the stopping block 81 communicating with the shaft hole 811 , the soleplate 1 is provided with a through hole 12 , and a damper 84 is inserted through the through hole 12 and the damping adjustment hole 812 , the damper 84 can adjust the gap between the sliding shaft 82 and the shafting hole 811 , in order to control the speed and strength of the slider 4 during the horizontal movement , so as to adapt to users of different constitution . for convenient processing , the pillow 2 , the spring seat 6 , the supporting base 3 with semicircle bottom surface , the slider 4 and soleplate 1 in this embodiment are all formed by injection molding in one time , while the elastic cushion 21 disposed on the pillow 2 is formed by impact molding in one time . standard fasteners are preferably used as fasteners ( screws , etc .) between all components . in this embodiment , the curve top surface of the pillow 2 , matching a natural physical curvature of human spine , is mainly used for realizing the exercise of cervical spine . when in service , the rehabilitation exercise device is placed on a horizontal plane ; a person lies on his back with both lower limbs bent at 90 degrees and both feet spaced apart at an interval equal to the shoulders ; and the exercise device is placed below the neck , with the center of the cervical spine facing the center of the curved face of the pillow 2 . a new user is better to hold the two ends of the pillow 2 by both hands so as to assist the cervical spine to do horizontal movement back and forth on the camber . when the user lowers his head so that the shoulders go down , the pillow 2 moves upward ; and when the user raises his head so that the shoulders and the waist rise up , the pillow 2 moves downward . each back - and - forth movement of the pillow 2 is a period of exercise . for a new user , the number of the periods of exercise should be increased progressively from less to more , depending on individual difference , such as constitution . embodiment 2 , as shown in fig8 and fig9 , the difference between this embodiment and embodiment 1 is that , in this embodiment , the pillow has a curve top surface special for thoracolumbar spine , mainly for the exercise of thoracolumbar spine ; and the pillow 2 comprises an elastic cushion 21 , wherein the middle part of the curve top surface special for thoracolumbar spine is formed with an arc depression 24 matching spinel evagination . the arc depression 24 is soft and flexible , and the portion of the arc depression 24 is formed with an elastic bump 25 matching the depression in size , so that the outer surface of the elastic cushion 21 forms a block protruding outward . therefore , a user with thoracolumbar spine kyphosis may feel more conformable when doing exercise and the effect of rehabilitation by exercise may be ensured . when in service , the rehabilitation exercise device in this embodiment is placed on a horizontal plane , and a person lies on his back with both lower limbs bent at 90 degrees and both feet spaced apart at an interval equal to the shoulders . the specific massage method will be described as below : ( 1 ) exercise of lumbosacral spine : the rehabilitation exercise device is placed in the center of the waist corresponding to the navel , with the center of the spine facing the center of the pillow . when the jaw and the lower back rise up and the hip goes down , the pillow 2 moves upward ; and when the jaw and the lower back go down and the hip rises up , the pillow 2 moves downward . each back - and - forth movement of the pillow 2 is a period of exercise . for a new user , the number of periods of exercise should be increased progressively from less to more , depending on individual difference , such as constitution . ( 2 ) exercise of lower thoracic spine : the rehabilitation exercise device is placed under the back at three inches above the navel ( four transverse fingers ) corresponding to the stomach , with the center of the spine facing the center of the pillow 2 . when , the jaw and the shoulders rise up and the waist and the hip go down , the pillow 2 moves upward ; and when the jaw and the shoulders go down and the waist and the hip rise up , the pillow 2 moves downward . each back - and - forth movement of the pillow 2 is a period of exercise . for a new user , the number of periods of exercise should be increased progressively from less to more , depending on individual difference , such as constitution . ( 3 ) exercise of upper thoracic spine : the rehabilitation exercise device is placed under the chest - back taking the nipple as center , with the center of the thoracic spine facing the center of the pillow 2 . when the jaw and the shoulders rise up and the waist and the hip go down , the pillow 2 moves upward ; and when the jaw and the shoulders go down and the waist and the hip rise up , the pillow 2 moves downward . each back - and - forth movement of the pillow 2 is a period of exercise . for a new user , the number of periods of exercise should be increased progressively from less to more , depending on individual difference , such as constitution .
