  • The handle 30 is mounted securely around the second end 22 of the connecting tube 20, is elongated, extends to the middle segment 23 of the connecting tube 20 and is adjacent to the main body 10.
  • The extension spring 40 is axially and extendably mounted in the connecting tube 20 and has a fastener end and a striker end opposite to the fastener end. As long as the extension spring 40 is extendable and can recover to an original position, the present invention does not limit a spring constant, a size or a weight of the extension spring 40.
  • With further reference to FIG. 4, the fastening device 50 is connected securely with the connecting tube 20 and the extension spring 40. The fastening device 50 is mounted in the middle segment 23 of the connecting tube 20 and has a base 51, a cushion spring 52, a fastener 53, a fastener bolt 54 and multiple screws 55. The base 51 is mounted securely in the connecting tube 20. The cushion spring 52 is compressibly mounted between the base 51 and the first end 21 of the connecting tube 20 and abuts the base 51. The fastener 53 is slidably mounted between the first end 21 of the connecting tube 20 and the cushion spring 52, abuts the cushion spring 52 and has an outer surface and a threaded section 531. The threaded section 531 is formed around the outer surface of the fastener 53 and is axially inserted securely into the fastener end of the extension spring 40. The fastener bolt 54 is mounted through the fastener 53 and the cushion spring 52 and is screwed securely into the base 51 to offer a force that makes the fastener 53 press the cushion spring 52. The screws 55 are radially mounted into the middle segment 23 of the connecting tube 20 and are radially screwed securely into the base 51.
  • The striker 60 is slidably mounted in the connecting tube 20 between the extension spring 40 and the first end 21 of the connecting tube 20. The striker 60 has a knob 61, a threaded segment 62 and a rod 63. The knob 61 is mounted outside and abuts the striker end of the extension spring 40. The threaded segment 62 is axially inserted securely into the striker end of the extension spring 40 and is securely connected with the knob 61. The rod 63 is mounted in the extension spring 40 and is connected securely with the threaded segment 62.
  • With further reference to FIG. 5, the securing device 70 is mounted in the main body 10, is mounted between and securely connected with the first end of the main body 10 and the first end 21 of the connecting tube 20 and has a securer 71, a washer 72 and a washer bolt 73. The securer 71 is axially screwed securely into the first end 21 of the connecting tube 20 and is securely connected with the first end of the main body 10. The washer 72 is mounted in the connecting tube 20 and abuts the securer 71. The washer bolt 73 is mounted in the connecting tube 20, is axially mounted through the washer 72 and is axially screwed securely into the securer 71.
  • With further reference to FIGS. 2, 6 and 7, when the swing training bat in accordance with the present invention is in use, the handle 30 is gripped by a batter and the swing training bat is swung in a correct way to generate a centrifugal force. The centrifugal force is applied to the striker 60 and makes the striker 60 slide toward the securing device 70. Accordingly, the extension spring 40 is expanded by the striker 60 because the threaded segment 62 is securely connected with the striker end of the extension spring 40. Consequently, the striker 60 strikes the securing device 70 to make a sound which allows the batter to know whether the batter's swing is correct. Accordingly, the expanded extension spring 40 generates a recovering force capable of pulling back the striker 60 and reducing a big bumping force between the striker 60 and the securing device 70. To reduce the bumping force can relieve damage to the batter's hands.
  • When the striker 60 is pulled back to compress and push down the extension spring 40, the fastener 53 compresses the cushion spring 52. Consequently, the cushion spring 52 can cushion the fastener 53, the extension spring 40 and the striker 60.
  • Additionally, different spring constant, size or weight of the extension spring 40 can be chosen to fit different batter's needs. From the above description, it is noted that the present invention has the following advantages:
  • 1. Relieving damage to a batter's hands:
  • Because the extended extension spring 40 generates a covering force capable of pulling back the striker 60 and reducing a big bumping force, to reduce the bumping force can relieve damage to a batter's hands.
  • 2. Cushioning the fastener 53, the extension spring 40 and the striker 60:
  • When the striker 60 is pulled back to compress the extension spring 40, the fastener 53 compresses the cushion spring 52. Therefore, the fastener 53, the extension spring 40 and the striker 60 can be cushioned by the cushion spring 52 when the striker 60 is pulled back.
  • 3. Good versatility for different batters:
  • Because different spring constant, size or weight of the extension spring 40 can be chosen to fit different batter's needs, the swing training bat in accordance with the present invention is versatile in use.
  • Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
