| 摘要 | A device and method for teaching a person the proper way to swing a baseball bat. The swing trainer comprises an elongated shaft having a circular cross-section with a grip handle on one end of the shaft and a head on the other end. A stop is located in the area where the shaft and handle meet and a slide is mounted on the shaft for movement along the shaft between the head and the stop. To use the trainer, the user places one hand on the handle of the swing trainer and the other on the slide. As the user swings the trainer, the user moves the slide along the shaft toward the handle until the handle contacts the stop and the user's hands are close together. This movement of the hands and slide during the swing causes the batter to swing the bat outwardly, away from the body. | ||||||
