发明名称 Massaging structure with a buffer function
摘要 A massaging structure with a buffer function includes a threaded rod positioned in a frame, and a coil spring respectively provided at an upper end section and a lower end section of the threaded rod. When a moving member of a massaging roller moves to the highest point or to the lowest point of the threaded rod, a micro switch at the highest point and at the lowest point of the threaded rod is contacted by the moving member, turned on and activating a motor to reverse its rotating direction. If the motor stops in case of a disorder, the coil springs can let the moving member jump up and down so that a user may know a disorder happened and correct it. Thus, the threads of the threaded rod and the moving member can be protected from damage.
