RELATE APPLICATIONS 
     This application is a national phase entrance of and claims benefit to PCT Application for Spine Rehabilitation Exercise Device thereof, PCT/CN2013/000022, filed on Jan. 14, 2013, which claims benefit to Chinese Patent Application 201210414931.7, filed on Oct. 25, 2012. The specifications of both applications are incorporated here by this reference. 
     FIELD OF THE INVENTION 
     The present invention relates to a health care equipment, particularly to a human spine rehabilitation exercise device. 
     DESCRIPTION OF THE PRIOR ART 
     As an axial skeleton of a human being, spine (also known as backbone), called “the second lifeline of human body” by medical experts, not only has functions of supporting the body and buffering the stress and shock on the body, but also is a support center of chest and abdomen with functions of protecting visceral organs of chest and abdomen and spinal cord, therefore, the importance of the spine to human heath is self-evident. 
     For most people, one of the main causes of spinal injury is keeping a post unchanged for a long time. For example, people, working over a desk, generally sit in front of a computer for a long time. Keeping the head forward becomes a normal state both in work and life, which brings large loads to the spine; as a result, it is likely to cause spinal abnormality. Spinal abnormality may not only cause neck pain, shoulder pain, back pain and numbness of limb, but also affect blood vessels near the spine and disrupt nerves managing the viscera, thereby resulting in disorder of breath, digestion, circulation and other systemic functions. Consequently, many people are in ailment or sub-health status, and the quality of work and life is influenced seriously. 
     To prevent and treat various spinal diseases, there has been various health care appliances and medical facilities for massaging the spine in the prior art. For example, U.S. Pat. No. 6,899,688 disclosed a cervical spine massager, the massager has a driving device, two shaft seats are disposed on the driving device, and each of the shaft seats is provided with a shaft lever in connection with a roll sleeve; and when the driving device moves, the roll sleeves can move along the curve of the cervical spine of the user, which meets the requirement of the physiological radian of the human cervical spine, so that the user is allowed to be massaged comfortably. Furthermore, Chinese Utility Model Patent No. CN202342417U (Patent No.: ZL201120385769.1), entitled “Human Spine Curve Massager”, disclosed a human spine curve massager, where the human spine curve massager consists of a soleplate, a massage block and a supporting block fixed on the soleplate, and an electronic oscillator; the upper surfaces of the massage block and the supporting block form a curved surface similar to the human spinal curve; and, when a person lies on the massager on his back, the spine may be in a completely relaxed state, at this moment, the tired and sore parts are massaged using the massage block in the presence of high frequency pulse current generated by the electronic oscillator, accompanied by radio wave stimulation for physiotherapy, thereby generating excellent effects in relieving fatigue and pains. 
     However, the massages described in the above patents have a common problem that they need to be connected to a power supply when in service. The action of the massagers is to be driven by a motor or generated by an electronic oscillator. Once the electronic circuit is damaged or breaks down, the massagers are unable to operate normally so that the service life of the massagers is limited by electronic equipment. Furthermore, a risk of current leakage of the electronic equipment may cause safety problems in service. Second, massagers applying an electronic driving device generally have large size, complicated structure and poor mobility and portability, thereby resulting inflexible use. In addition, when the massagers described in the above patents are in service, generally, the position of a person is kept unmoved relatively while the massage heads on the massagers do reciprocating motion, so that only parts of acupuncture points of cervical spine or spine can be massaged passively, and the active training and exercise to intraspinal nerves and visceral organs in the chest and abdomen cannot be further realized. The effect of comprehensive health care is not ideal. Hence, in order to solve the problems existed in the above patents and achieve the purpose of optimizing the structure and improving the health care effect, such massagers need to be further improved.
