DETAILED DESCRIPTION

[0019] Based on the embodiments of the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4The adjustable tire centering structure comprises a base 1, a support frame 2 arranged above the base 1, a driving piece 3 embedded in the middle part of the upper side of the base 1, and a gear 4 connected to the lower side of the support frame 2 and driven by the driving piece 3. The upper side of the support frame 2 is provided with sliding frames 5 at the left and right ends, and the upper side of the support frame 2 is symmetrically provided with strip-shaped sliding grooves 6. The front and rear sides of the support frame 2 are provided with guide rods 13, and the lower side of the sliding frame 5 is slidably connected with the guide rods 13.

[0022] The lower side of the sliding frame 5 is slidably connected with the strip-shaped sliding groove 6, the lower side of the support frame 2 is provided with a gear rack 7 engaged with the gear 4, and the upper side of the base 1 is provided with a stable sliding groove slidably connected with the lower side of the gear rack 7.

[0023] One side of the gear rack 7 is provided with a transmission block 8, the upper side of the transmission block 8 penetrates through the strip-shaped sliding groove 6 and is connected with the lower side of the sliding frame 5, the upper side of the sliding frame 5 is provided with a strip-shaped opening extending forward and backward, the strip-shaped opening is rotatably connected with a bidirectional screw rod 9 through a bearing, and two limit assemblies are arranged on each bidirectional screw rod 9 through screw connection. A triangular reinforcing block 14 is arranged at the connection position of the connecting seat 11 and the moving seat 10.
