Benefits of technology
[0008]The main objective of the invention is to provide a swing training bat which can cushion a bumping force and relieve damage to a batter's hands.
[0009]A swing training bat has a main body, a connecting tube, a handle, an extension spring, a fastening device, a striker and a securing device. The extension spring, the fastening device and the striker are mounted in the connecting tube. The extension spring is extendable and has two ends securely connected with the fastening device and the striker. The striker is capable of bumping the securing device when the swing training bat is swung. Because the extended extension spring generates a covering force capable of pulling back the striker and reducing a big bumping force between the striker and the securing device, to reduce the bumping force can relieve damage to a batter's hands.
Problems solved by technology
However, a big bumping force between the sliding weight 84 and the blocker 83 easily causes damage to the batter's hands.
The big bumping force is not safe for the batter.

Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a bat of baseball or softball, and more particularly to a swing training bat which can reduce a bumping force and relieve damage to a batter's hands.[0003]2. Description of Related Art[0004]A conventional swing training bat is used to train a batter's swing in baseball or softball. With reference to FIG. 8, the conventional swing training bat has a rod 81, a handle 82, a blocker 83 and a sliding weight 84. The rod 81 has two ends. The handle 82 and the blocker 83 respectively are mounted securely around the ends of the rod 81. The sliding weight 84 is slidably mounted around the rod 81 between the handle 82 and the blocker 83 and normally abuts the handle 82.[0005]When the conventional swing training bat is swung by a batter in a correct way, the sliding weight 84 is quickly slid and bumps the blocker 83 to make a loud sound which allows the batter to know whether the batter's swing is c...
