DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] As Figures 1-3 shown, a bracket for repairing automobile wheels in the figure includes a main body 1 and a clamping mechanism arranged inside the main body 1. The clamping mechanism includes a clamping assembly and a pushing assembly;

[0025] The clamping assembly includes a chassis 2. The chassis 2 is arranged inside the main body 1. A first connecting piece 3 is fixedly connected to the outer wall of the chassis 2. A first connecting rod 4 is rotatably connected to the inner wall of the first connecting piece 3. One end of the first connecting rod 4 is rotatably connected to a clamping body 5. A second connecting rod 6 is rotatably connected to the inner wall of the clamping body 5. One end of the second connecting rod 6 is rotatably connected to a second connecting piece 7. A disc 8 is fixedly connected to the outer wall of the second connecting piece 7.

[0026] The pushing assembly includes a push rod 9. The push rod 9 is fixedly connected to the outer wall of the chassis 2. One end of the push rod 9 is fixedly connected to a hydraulic rod 10. The end of the hydraulic rod 10 away from the push rod 9 is slidably connected to a cylinder 11.

[0027] Among them, as Figure 3 shown, there are three groups of clamping bodies 5. The positional relationship of the three groups of clamping bodies is equidistantly distributed about the midpoint of the chassis 2, which is beneficial to more stable and steady clamping and fixing operations on the main body 1, avoiding the problem of secondary damage during repair due to instability during fixing, and realizing the control operation of fixing the main body 1.

[0028] Among them, as Figure 3 shown, the clamping body 5 and the push rod 9 form a pushing structure through the first connecting rod 4 and the second connecting rod 6, which is beneficial to the relatively simple process of clamping and fixing and disassembling the main body 1 by the clamping body 5, avoiding the need for relatively cumbersome fixing and disassembling of the main body 1, and realizing the control operation of clamping and fixing the clamping body 5.

[0029] Among them, as Figure 3 shown, the disc 8 and the push rod 9 form a sliding structure through the cylinder 11 and the hydraulic rod 10, which is beneficial to using the cylinder 11 to more quickly fix or disassemble the main body 1, avoiding the problem of obstacles during repair caused by errors during manual fixing, and realizing the control operation of fixing the main body 1. Embodiment

[0030] As Figure 1 、 Figure 2 and Figure 4 shown, a hook 12 is arranged at the top inside the main body 1. The top of the hook 12 is fixedly connected to a threaded column 13. The top of the threaded column 13 is rotatably connected to a fixing column 14. The top of the fixing column 14 is fixedly connected to a clamping plate 15. A rivet 16 penetrates through the outside of the clamping plate 15. A gantry 17 is arranged on the inner wall of the clamping plate 15. The bottom of the gantry 17 is fixedly connected to a base 18.

[0031] Among them, as Figure 4As shown, the appearance of the lifting hook 12 is in a "C" shape. The lifting hook 12 and the fixed column 14 form a rotating structure through the threaded column 13, which is beneficial for the lifting hook 12 to stably lift the main body 1, avoiding unexpected situations during the repair process due to the shaking of the main body 1 during repair and the problem that the lifting hook 12 cannot be replaced due to wear during long-term use, and realizing the control operation of fixing the lifting hook 12.

[0032] Among them, as Figure 4 shown, a limiting groove matching the rivet 16 is opened on the outer wall of the gantry 17. The lifting hook 12 and the gantry 17 form a sliding structure through the clamping plate 15 and the rivet 16, which is beneficial for fixing and repairing main bodies 1 of various models, avoiding the problem of excessive limitations caused by the inability to repair main bodies 1 of other sizes, and realizing the control operation of sliding the clamping plate 15.

[0033] During use: First, the cylinder 11 is fixed on the gantry 17 through setting. When the main body 1 needs to be repaired, the hole in the middle of the main body 1 is aligned with the chassis 2 and then inserted. The cylinder 11 pushes the hydraulic rod 10 outward, causing the push rod 9 to push the chassis 2 outward synchronously, so that the first connecting rod 4 in the first connecting piece 3 on the chassis 2 pulls the clamping body 5 outward, and the second connecting rod 6 pulls the disc 8 on the second connecting piece 7 to clamp and fix the main body 1, avoiding the problem of secondary damage during repair caused by inaccuracy due to instability during fixing.

[0034] Finally, the gantry 17 is fixed on the base 18 through setting. After the main body 1 is fixed, the two lifting hooks 12 are inserted into the main body 1 to hook it. When fixing main bodies 1 of other sizes, the rivet 16 fixed to the clamping plate 15 and the gantry 17 is removed, and then the clamping plate 15 is moved outward or inward of the gantry 17 to align the hole positions on its surface with the hole positions on the gantry 17, and then the rivet 16 is inserted. When the lifting hook 12 needs to be replaced, the lifting hook 12 is rotated to turn it out of the fixed column 14 through the threaded column 13, avoiding unexpected situations during the repair process due to the shaking of the main body 1 during repair and the problem that the lifting hook 12 cannot be replaced due to wear during long-term use.
