Abstract
An foldable electric traction machine comprises a front beam, a rear beam and a joint connecting the front beam and the rear beam. A motor is mounted beneath the rear beam. A sliding bracket is mounted on an extension beam and can be moved by the motor. The body of a patient lying on the traction machine will be stretched by the motor driving the sliding bracket along the extension beam. A rope is provide under the front and the rear beam and will be gradually tensioned with the movement of the sliding bracket. Therefore, when the motor is operated, the traction machine not only can improve the user's body condition, but also raise the user's waist.
