Description

Technical Field

[0001] The utility model relates to a sports apparatus, specifically an apparatus for tennis hitting training. Background Art

[0002] With the continuous development of the global regional economy and the continuous improvement of people's pursuit of the quality of life, tennis attracts more and more ordinary people because of its high ornamental and entertaining properties, and now more and more people begin to learn it. Using tennis training equipment is an effective means for practitioners to practice the correct hitting posture, and a large number of tennis hitting training equipment has been developed. For the need to facilitate practice on sites without special requirements, some tennis trainers adopt a portable design. For example, the portable tennis trainer disclosed in the application number 201920872237.7 uses a detachable bracket and a rotatable tennis ball on the ball seat. Since its tennis ball is in a completely exposed state and the ball seat is small, it is not conducive to guiding the trainer to form the correct hitting action and the hitting difficulty is high, and it is easy to touch the ball seat. At present, there are also tennis training apparatuses with hitting actions on the market. For example, the tennis trainer disclosed in the design patent with the patent application number CN202030354530.2 uses a bent steel bar as the ball seat, and the ball seat can swing simultaneously, which can make the tennis ball have a better hitting space. At the same time, it has a guiding racket located above the tennis ball to guide the trajectory of the tennis racket (the tennis racket swings along the surface of the guiding racket and cannot touch the guiding racket). In order to achieve portability and reliable hitting, the above two can be combined to obtain a solution with corresponding advantageous combinations more easily, but it still has the following deficiencies: 1. There is only a guiding racket above the tennis ball, which cannot better standardize the hitting action; 2. The bracket structure is complex and the disassembly and assembly operations are inconvenient; 3. The adjustability of the bracket is insufficient, which is not conducive to different trainers to adjust according to their needs. Summary of the Invention
