[0024] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the locking assembly includes multiple groups of fixing seats 7 respectively installed on the output end of the cylinder 3 and the adjusting mechanism, the fixing seat 7 is provided with a mounting groove inside, a limiting seat 8 is installed at one end of the inner side of the mounting groove, the inner side of the limiting seat 8 is slidably connected with a limiting plate 9, and a first spring is installed between one side of the limiting plate 9 and the inner side of the limiting groove. First, the docking block 12 on the connecting plate 11 is aligned with the docking groove and inserted, so that the docking block 12 contacts and squeezes the inclined surface on the extrusion block 10, so that the extrusion block 10 drives the limiting plate 9 to compress the first spring to retract, and at the same time, compresses the second spring to retract.

[0025] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, an extrusion block 10 is installed at one end of the limiting plate 9, and a first groove is provided on one side of the extrusion block 10. A connecting plate 11 is attached to one side of the fixing seat 7, and a docking block 12 is installed at one end of the connecting plate 11. A docking groove is provided on one side of the fixing seat 7, and the docking groove and the docking block 12 are slidably connected. A second groove is provided on one side of the docking block 12, and the opposite ends of the docking block 12 and the extrusion block 10 are provided with inclined surfaces that fit each other. A fixing groove is provided on the other side of the extrusion block 10, and a second spring is installed between the inner side of the fixing groove and the inner wall of the installation groove. Then, after the inclined surfaces on the docking block 12 and the extrusion block 10 are misaligned with each other, the protruding ends of the two are inserted into each other's first groove and second groove for locking and connecting.

[0026] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, the closing buckle pulling assembly includes a pulling rod 13 installed on one side of the extrusion block 10. An extension groove is formed on one side of the fixed seat 7. The inner wall of the extension groove is provided with a pulling groove extending to the inside of the installation groove. The pulling rod 13 is slidably connected to the pulling groove. One end of the pulling rod 13 extending to the inside of the extension groove is rotatably connected with a buckle ring. A closing plate 14 is slidably connected to the inside of the extension groove. The closing plate 14 is hinged to the fixed seat 7 through a hinge. A buckle pulling groove is formed on one side of the closing plate 14. A magnetic strip is embedded at one end of the closing plate 14. An iron block 15 adsorbed to the magnetic strip is embedded on the inner wall of the extension groove. One end of one group of connecting plates 11 is fixedly connected to one side of the correction body 6. One end of the other two groups of connecting plates 11 is fixedly connected to one side of the two inner clamping plates 4. One end of the other two groups of connecting plates 11 is fixedly connected to one side of the two outer clamping plates 5. The output end of the air cylinder 3 is fixedly connected to one side of one of the fixed seats 7. Further, buckling the buckle pulling groove and cooperating with the hinge can drive the closing plate 14 to flip and unfold. The magnetic strip and the iron block 15 move away from each other and no longer adsorb. At this time, the buckle ring is exposed. Buckling the buckle ring drives the pulling rod 13 to slide inside the pulling groove, driving the extrusion block 10 to cooperate with the limiting plate 9 and the limiting groove to actively extrude the first spring and the second spring to retract. At this time, the connecting plate 11 can be held to drive the docking block 12 to separate, and the inner clamping plate 4, the outer clamping plate 5 and the correction body 6 can be separated and disassembled for replacement.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the adjusting mechanism includes an adjusting groove formed inside the adjusting seat 2. A threaded rod 16 is rotatably connected to the inside of the adjusting groove. Both ends of the outer side of the threaded rod 16 are threadedly connected with adjusting plates 17. The adjusting plates 17 are slidably connected to the inside of the adjusting groove. One end of the adjusting plate 17 is fixedly connected to one side of four of the fixed seats 7. A first motor is installed at one end of the adjusting seat 2. The driving end of the first motor extends to the inside of the adjusting groove and is fixedly connected to one end of the threaded rod 16. Further, place the edge of the tire spacer between the inner clamping plate 4 and the outer clamping plate 5. Then start the first motor to drive the threaded rod 16 to rotate, so that the two adjusting plates 17 drive the inner clamping plate 4 and the outer clamping plate 5 to clamp and position the tire spacer. Then start the air cylinder 3 to drive the correction body 6 to perform a repair operation.

[0028] The implementation principle of a calibration tool for a tire spacer sleeve in an embodiment of the present application is as follows: Align the docking block 12 on the connecting plate 11 and insert it into the docking groove, so that the docking block 12 contacts and presses against the inclined surface on the extrusion block 10, causing the extrusion block 10 to drive the limit plate 9 to compress the first spring and retract, and at the same time compress the second spring to retract. When the inclined surfaces of the docking block 12 and the extrusion block 10 are misaligned with each other, the protruding ends of the two snap into the first groove and the second groove of each other respectively for locking and clamping. By pulling the buckle groove in cooperation with the hinge, the closing plate 14 can be driven to flip and unfold, and the magnetic strip and the iron block 15 move away from each other and no longer adsorb. At this time, the buckle ring is exposed. Pulling the buckle ring drives the drag rod 13 to slide inside the drag groove, driving the extrusion block 10 to cooperate with the limit plate 9 and the limit groove to actively compress the first spring and the second spring to retract. At this time, the connecting plate 11 can be held to drive the docking block 12 to separate, and the inner clamping plate 4, the outer clamping plate 5 and the calibration body 6 can be separated and disassembled for replacement. Place the edge of the tire spacer sleeve between the inner clamping plate 4 and the outer clamping plate 5, and then start the first motor to drive the threaded rod 16 to rotate, so that the two sets of adjusting plates 17 drive the inner clamping plate 4 and the outer clamping plate 5 to clamp and position the tire spacer sleeve. Then start the cylinder 3 to drive the calibration body 6 to perform the repair operation.
