[0002] Utility model patent application number CN201620689624.3 discloses a portable tennis practice device, including a base, a support, a cross arm, and a hitting assembly. The support is telescopic and detachably connected to the base. One end of the cross arm is hinged to the support, and the other end is connected to the hitting assembly. The hitting assembly consists of a ball and a hanging arm connected to the ball. This portable tennis practice device is easy to carry, allowing for training anytime, anywhere. Furthermore, the hitting assembly can be fixed at any angle, facilitating practice.

[0003] The aforementioned patent features a telescopic bracket and crossarm, with a detachable connection between the bracket and the base. A rotating component is installed on the crossarm to allow the ball to rotate along the arm. However, during tennis hitting training, the tennis ball causes the arm to rotate around the circumference of the crossarm, resulting in the tennis ball and arm getting tangled on the crossarm. Trainees need to repeatedly remove the tennis ball and arm from the crossarm, which is exhausting and results in poor training continuity.

[0004] Therefore, we made improvements and proposed a portable tennis training machine. Utility Model Content

The training frame 4 has a slide bar 19 in the middle, and slide grooves 12 are opened on both sides of the slide bar 19. Multiple fixing grooves 13 are opened at the bottom of the slide grooves 12. The movable block 5 has a limiting groove 14 inside, and a slider 16 that slides with the slide groove 12 is slidably engaged in the limiting groove 14. A threaded groove 15 is opened through the inner wall of the limiting groove 14. A threaded rod 17 that is threaded in the threaded groove 15 is rotatably engaged on the side of the slider 16. A fixing block 18 that mates with the fixing groove 13 is installed on the other side of the slider 16.

[0036] Implementation process: A baffle 801 is installed above the training frame 4. The baffle 801 is installed in the connecting groove 805 and mounting groove 804 of the training frame 4 through the connecting column 802 and mounting block 803 at the bottom. This prevents the tennis ball 6 at the bottom of the moving block 5 from being blocked when it rotates through the baffle 801 after being hit, thus preventing the hanging arm 11 on the tennis ball 6 from getting tangled on the sliding rod 19 of the training frame 4. This ensures the continuity of the training when the trainee is practicing with the tennis ball 6. By rotating the threaded rod 17, the slider 16 can be moved in the limiting groove 14. When the slider 16 is in the sliding groove 12 and the fixed block 18 is away from the fixed groove 13, the moving block 5 can be slid on the sliding rod 19 to adjust the position of the tennis ball 6. When the slider 16 moves into the limiting groove 14 and away from the sliding groove 12, the moving block 5 can be rotated on the sliding rod 19.
