[0045] Example 1

[0046] This embodiment relates to a basketball training device that can correct the user's incorrect shooting posture and help the user maintain the correct shooting posture. Figures 1 to 8 As shown, the basketball training device of this embodiment includes a base 1 , a transfer rod 12 arranged on the base 1 and extending in the height direction, and a training device body 2 arranged at the upper end of the transfer rod 12 .

[0047] Among them, the training device body 2 includes a hollow connecting tube 21 mounted on the upper end of the adapter rod 12, a shooting assembly 22 hinged at one end of the hollow connecting tube 21, and an elbow assist device 23 fixedly connected to the other end of the hollow connecting tube 21. The shooting assembly 22 and the elbow assist device 23 are arranged on the same side of the hollow connecting tube 21, and a telescopic rod 24 is provided between the two.

[0048] The shooting assembly 22 includes an arm 221, a semicircular bracket 222 mounted on the arm 221, and two clamps 223 slidably mounted on either end of the semicircular bracket 222. The two clamps 223 are positioned close to each other to secure the basketball. The elbow assist device 23 includes an elbow 231, a connecting rod 232 mounted on the elbow 231, and a support 233 connected to the connecting rod 232 to stabilize the elbow.

[0049] At this time, as set up above, the arm rod 221, the semicircular bracket 222, and the clamping member 223 in the shooting assembly 22 can fix the basketball and determine the position of the user's palm. The elbow rod 231, the connecting rod 232, and the supporting seat 233 in the elbow auxiliary device 23 can ensure that the user's elbow remains stable. At the same time, the coordination between the above components can correct the user's incorrect shooting posture and help the user maintain a correct shooting posture.

[0050] During specific implementation, the user places the elbow on the support seat 233. If the upper arm cannot be parallel to the ground and perpendicular to the body at this time, it is necessary to adjust the height between the trainer body 2 and the base 1 until an appropriate and comfortable position is reached. Then, the semicircular bracket 222 is pulled down to near the palm, and the shooting angle is kept at about 45 degrees when shooting.

[0051] At the same time, by adjusting the positions of the various components in the shooting assembly 22 and the elbow assist device 23, it is ensured that the user's shoulder and upper arm are at 90 degrees, the upper arm and forearm are at 90 degrees, and the wrist and forearm are at 90 degrees. After completing the above preparations, training can begin, thereby ensuring that the user maintains the correct shooting posture.

[0052] Based on the above overall introduction, in this embodiment, as a preferred implementation form, Figure 1 、 Figure 4 and Figure 8 As shown, both ends of the semicircular bracket 222 are spirally provided with connecting members 224.
