[0026] Please see Figures 1-4 This utility model proposes a tire fixing device for automobile repair, including a base 1, a trapezoidal support seat 2 fixedly connected to the upper side of the base 1, a support component 3 provided inside the trapezoidal support seat 2, a bracket 4 fixedly connected to the upper side of the base 1, and a fixing component 5 provided on the bracket 4.

[0027] In this embodiment of the invention, in order to support the tire, the support assembly 3 specifically includes an inner groove 31, in which an electric cylinder 32 is fixedly installed. A sliding plate 33 is fixedly connected to the output end of the electric cylinder 32. The sliding plate 33 is slidably connected in the inner groove 31. A rotating roller 34 is rotatably connected to the upper side of the sliding plate 33. A support roller 35 is rotatably connected in the inner groove 31. Two sets of support rollers 35 are provided, and the two sets of support rollers 35 are symmetrically arranged with the center line of the inner groove 31 as the axis of symmetry. By rolling the tire onto the trapezoidal support seat 2, the two sets of support rollers 35 can support the tire. When the tire needs to be removed, the output end of the electric cylinder 32 drives the sliding plate 33 to rise, so that the rotating roller 34 can push out the tire, making it easier for the tire to be removed from the inner groove 31 and thus easier to remove the tire from the trapezoidal support seat 2. This method is applicable to tires of different specifications and models, reducing the labor intensity of maintenance personnel.

[0028] Furthermore, to secure the tire, the fixing assembly 5 specifically includes a motor 51, an arc-shaped rod 54, and a hinge rod 57. A turntable 52 is fixedly connected to the output shaft of the motor 51. A small cylinder 53 is fixedly connected to the side of the turntable 52 away from the motor 51. One end of the arc-shaped rod 54 is rotatably connected to the small cylinder 53, and the other end of the arc-shaped rod 54 is hinged to a moving block 55, which is slidably connected in the guide rail 56. One end of the hinge rod 57 is hinged to the outer wall of the moving block 55, and the other end of the hinge rod 57 is hinged to the outer wall of the rotating arm 58. A pressure roller 510 is fixedly connected to the outer wall of the rotating arm 58. The motor 51 is fixedly connected to the outer wall of the bracket 4, and the rotating arm 58 is rotatably connected to the fixed... Positioning rod 59 is fixedly connected to the outer wall of bracket 4. Limiting sleeve 511 is fixedly connected to the side of bracket 4 near turntable 52. The output shaft of motor 51 passes through limiting sleeve 511 and is rotatably connected to limiting sleeve 511. The output shaft of motor 51 drives turntable 52 to rotate, thereby driving arc rod 54 and moving block 55 to move in guide rail 56. The rotating arm 58 is rotated by the action of hinge rod 57, so that pressure roller 510 presses the tire. At the same time, the cooperation between pressure roller 510 and support roller 35 ensures the stability of tire during maintenance and effectively prevents tire loosening or slippage when rotating the tire, providing a safer and more stable maintenance environment for maintenance personnel.

[0029] It should be noted that the above electrical components are all existing technology products.

[0030] In use, the tire is first rolled onto the trapezoidal support seat 2, where two sets of support rollers 35 support the tire. Then, the motor 51 is started, and the output shaft of the motor 51 drives the turntable 52 to rotate, which in turn drives the arc rod 54 and the moving block 55 to move in the guide rail 56. The rotating arm 58 is rotated by the action of the hinge rod 57, so that the pressure roller 510 presses the tire. At the same time, the cooperation between the pressure roller 510 and the support roller 35 fixes the tire. After the staff has finished inspecting the tire, the electric cylinder 32 is started. The output end of the electric cylinder 32 drives the sliding plate 33 to rise, so that the rotating roller 34 can push out the tire, making it easier for the tire to be removed from the inner groove 31 and thus easier to remove the tire from the trapezoidal support seat 2.
