Therefore, in addition to the usual use of the pitching machine for dynamic strike practice, and placing the stick and the softball on the combat exercise base for static strike practice, another method is to slide the sleeve on the bat strike end by a swing weighter. The upper part is fixed to increase the weight of the bat, provide weight training, and strengthen the strength and speed of the striker's swing, thereby increasing the score and the chance of winning the game. However, the position of the swing jack stuck on the striking end of the bat is fixed and cannot be adjusted as needed. Therefore, it cannot be applied to the strikers of different arm forces, and the swing jack position cannot be freely adjusted. Let the muscles grow under the best conditions, and make the strike ability more refined. In addition, since the swing weighter is directly slid on the bat striking end, the swing weighter is prone to slippage and injury when used. The surface of the bat is quite unsatisfactory.
