[0029] Among them, the number of support plates 2 is three, the number of adjusting screws 41 is two, one end of the two adjusting screws 41 are rotatably connected to the two sides of the middle support plate 2, the other ends of the two adjusting screws 41 pass through the front and rear support plates 2, one end of the limiting rod 42 is fixedly connected to the middle support plate 2, and the other end passes through the front and rear support plates 2 respectively.

[0030] In addition, threaded holes located on the outside of the adjusting screw 41 are opened inside the front support plate 2 and the rear support plate 2. The threaded holes cooperate with the threads on the outside of the adjusting screw 41, so that when the adjusting screw 41 on one side is rotated, the support plate 2 on the same side can be driven to move forward and backward to adjust the distance with the middle support plate 2.

[0031] Secondly, the lower end of the placement plate 1 is convex, and the upper end of the support plate 2 is concave. The convex end of the placement plate 1 is matched with the concave end of the support plate 2, so that the lower end of the placement plate 1 and the upper end of the support plate 2 can be plugged and placed.

[0032] Then, a limiting groove is opened on the outside of the convex end of the placing plate 1 and is located on the outside of the pull rod 43.

[0033] See also Figure 4-5 In this embodiment, a placing piece 5 for placing arc-shaped steel bars is provided at the upper end of the placing plate 1, and the placing piece 5 includes a sliding block 53. A mounting groove 51 is opened at the upper end of the placing plate 1, and the sliding block 53 is slidably connected to the inner side of the mounting groove 51. A support rod 52 with one end passing through the sliding block 53 is fixedly connected to the inner side of the mounting groove 51, and a placing block 55 with one end extending to the outside of the mounting groove 51 is fixedly connected to the upper end of the sliding block 53.

Since the sliding block 53 can be slid and adjusted in the installation groove 51 by the support rod 52, and the rotating nut 56 can limit and fix the sliding block 53, during the process of preparing the steel cage, the position of the sliding block 53 in the installation groove 51 can be adjusted by loosening the nut 56, so as to adjust the placement spacing of the main reinforcement to adapt to the steel cage preparation with different requirements, thereby improving the adaptability of the entire tire frame.
