[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-8 The utility model provides a technical solution: a new baseball training device, which consists of a base 1, an aluminum hollow tube 2, a glass fiber support rod 3, a connecting piece 4 and a rubber ball holder 5. The ball holder 5 is trumpet-shaped, and the ball can be placed directly on the ball holder 5. Specifically,

[0025] The base 1 includes a bottom plate 11 and a bottom plate 2 12. The bottom plate 11 and the bottom plate 2 12 are vertically distributed on the horizontal plane to form a "cross"-shaped base. Compared with the previous base, this base 1 is further lighter in weight while meeting the stability, so that the gravity of the entire baseball training device is lighter and more convenient to carry. In addition, in order to make the bottom plates 11 and 12 fit better when spliced, a raised portion 121 is provided in the middle of the bottom plate 2 12. The width of the raised portion 121 is the same as that of the bottom plate 11, and the inner angle of the raised portion 121 is the same as that of the bottom plate 11. The corners with the bottom plate 11 are all set to right angles. The top of the raised part 121 is connected with a wire cylinder 122. The bottom of the hollow tube 2 is provided with an external thread 21. The external thread 21 is threadedly connected to the wire cylinder 122. When splicing and disassembling, the hollow tube 2 can be directly rotated. In order to facilitate the disassembly of the bottom plate 11 and the bottom plate 2 12, a through hole 111 is opened in the middle of the bottom plate 11, and a threaded hole 123 is opened at the bottom end of the raised part 121. When assembling, a screw 13 is passed through the inside of the through hole 111 and then threadedly connected to the threaded hole 123. The same applies to disassembly.

[0026] In order to facilitate the connection of the top end of the support rod 3 to the ball holder 5, the top end of the support rod 3 is connected to the upper convex shaft 31, and the bottom end of the ball holder 5 is integrally connected to the rubber head 51. When the support rod 3 and the ball holder 5 are connected, the rubber head 51 can be directly sleeved on the outside of the upper convex shaft 31. The rubber head 51 can be tightly sleeved on the outside of the upper convex shaft 31 by utilizing the contraction force generated by the deformation of the rubber head 51 itself.

[0027] To facilitate the connection between the bottom end of the support rod 3 and the hollow tube 2, a lower inner groove 32 is connected to the bottom end of the support rod 3, and a threaded hole 321 is opened inside the lower inner groove 32. In addition, a connecting piece 4 is used as a transition piece to connect the hollow tube 2 and the support rod 3. The connecting piece 4 includes a rubber sleeve 41 that is sleeved on the top of the hollow tube 2. The top of the rubber sleeve 41 is opened with a plurality of exhaust holes 411. The exhaust holes 411 are provided to allow the rubber sleeve 41 to balance the pressure inside and outside the hollow tube 2 when it is sleeved. The interior of the hollow tube 2 is provided with a buffer ring 42 made of sponge material. The support rod 3 passes through the rubber sleeve 41, the buffer ring 42 and the washer 43 and is fixedly connected to the screw 13. Because the bottom through hole of the washer 43 is compatible with the outer diameter of the screw, this allows these accessories to be locked. Then, the buffer ring 42 moves up and down by friction on the inner wall of the hollow tube 2. In this way, the support rod 3 can be hidden inside the hollow tube 2 or pulled up.

[0028] When assembling the baseball training device, first the base 1 is spliced, then the support rod 3 inside the hollow tube 2 is pulled up, and then the ball holder 5 is spliced ​​on the top of the support rod 3. Finally, the hollow tube 2, support rod 3, connector 4, and ball holder 5 are spliced ​​together with the base 1. The disassembly is done in the same way.

[0029] It should be noted that several hollow tubes 2 and support rods 3 can be provided and assembled according to the needs of the user. It is only necessary to set a small hollow tube 2 inside the hollow tube 2 to connect and fix it. These are all existing technologies and are therefore not shown in the figure.
