[0005] Furthermore, the frame is hemispherical and hollow inside.

[0006] Furthermore, the frame is circular.

[0007] Furthermore, adjusting nuts are provided on both sides of the connecting hole, and the fixed shaft is threadedly connected to the adjusting nuts.

[0008] Furthermore, the mounting connector is provided with mounting holes.

[0009] Furthermore, the concave surface of the glue-free pressure plate is provided with a central round tooth, and the back of the central round tooth is connected to a fixed shaft via a bearing.

[0010] Compared with the prior art, the advantages of this utility model are: This symmetrical pressure plate structure fixes the ball with a glue-free pressure plate, which is convenient to install and disassemble without damaging the ball itself; the positioning is stable and accurate, and the stability is high when rotating; it can improve children's hands-on ability and increase fun.

Therefore, they should not be construed as limitations on this utility model. Example 1

[0015] Please refer to Figure 1-3This embodiment provides a symmetrical pressure plate structure, including a frame 1, a glue-free pressure plate 2, a bearing 3, an adjusting nut 4, and a fixed shaft 5. The frame 1 is a hemispherical and hollow cover. The frame 1 has connecting holes I6 on both sides for connecting the fixed shaft 5. The frame 1 has adjusting nuts 4 on both the inner and outer sides at the connecting holes I6. The top of the frame 1 has a mounting joint 7 with mounting holes 8. The glue-free pressure plate 2 is an arc-shaped disc. The concave side of the glue-free pressure plate 2 has several evenly distributed round teeth 9. The round teeth 9 can position the ball without glue, avoiding damage to the ball. The center of the concave side has a central round tooth 10, which positions the ball concentrically and coaxially, facilitating rotation. The back of the central round tooth 10 has a connecting hole II. The bearing 3 is fixed in the connecting hole II of the glue-free pressure plate 2. One end of the fixed shaft 5 has an external thread and is screwed to the adjusting nut 4. The fixed position can be adjusted by adjusting the adjusting nut 4 to accommodate balls of various sizes. The other end is rotatably connected to the glue-free pressure plate 2 through the bearing 3.

[0016] This embodiment provides a symmetrical pressure plate structure. When in use, a ball such as a basketball or soccer ball is placed inside the frame 1. After pushing the glue-free pressure plate 2 against the basketball, the adjusting nut 4 is rotated until it is against both sides of the frame 1 to achieve fixation. After fixation, when the ball rotates, it drives the glue-free pressure plates 2 on both sides to rotate, forming a spherical tire. The mounting joint 7 on the frame 1 can be connected to a push rod for playing, or it can be connected to a car frame to form a toy car. Example 2

[0017] Please refer to Figure 4 The symmetrical pressure plate structure provided in this embodiment can be improved as follows compared with the technical solution of embodiment 1: the frame 1 is circular, and a mounting joint 7 is provided on one side of the frame 1. The mounting joint 7 is provided with a mounting hole 8, and the mounting joint 7 is perpendicular to the fixed shaft 5.
