The output end of the control motor 9 passes through the motor seat and is connected to a gear transmission unit for making the four horizontal screw rods 4 rotate synchronously. A fixed gear ring 10 is fixedly installed at the bottom of the placing table 3, and a mounting seat 11 is fixedly installed at the bottom of the annular workbench 1. A mounting hole is opened on the side of the mounting seat 11, and a driving shaft 12 is rotatably installed in the mounting hole. A driving gear 13 meshing with the fixed gear ring 10 is fixedly installed on one end of the driving shaft 12, and an adjusting dial 14 is fixedly installed on the other end of the driving shaft 12.

[0025] By means of the above structure, when the control motor 9 is started, the four horizontal screw rods 4 will be driven to rotate synchronously through the gear transmission unit. The simultaneous rotation of the four horizontal screw rods 4 will drive the four connecting columns 6 to move toward or away from each other at the same time through the movable arm 5, and then the inner wall or outer wall of the rim can be pressed and fixed through the inner wall abutment plate 7 or the outer wall abutment plate 8. Since the moving distances of the four connecting columns 6 are the same, the rim can always be pressed and positioned at the center of the placement table 3, and different fixing methods can be selected according to actual needs. The application range is wide. After the rim is pressed and positioned, when the adjusting dial 14 is rotated, the driving shaft 12 will drive the driving gear 13 to rotate. The rotation of the driving gear 13 will drive the fixed gear ring 10 to rotate, and then the placement table 3 and the rim can be driven to rotate together. There is no need for staff to carry tools to walk around the rim, which can greatly reduce the workload of staff. The operation is simple and convenient, and the practicability is good.

[0026] As a preferred implementation of this embodiment, the gear transmission unit includes a first bevel gear 15 fixedly mounted on the output end of the control motor 9, and the ends of the four horizontal screw rods 4 close to each other are fixedly mounted with second bevel gears 16 meshing with the first bevel gear 15. The advantage of this arrangement is that when the control motor 9 is running, it will drive the first bevel gear 15 to rotate, and the rotation of the first bevel gear 15 will drive the four second bevel gears 16 to rotate together, thereby driving the four horizontal screw rods 4 to rotate synchronously, playing a role of synchronous transmission.

[0027] As a preferred implementation of this embodiment, a fixing protrusion 17 is fixedly installed on the outer circumference of the annular workbench 1, a vertical sliding hole is provided on the top of the fixing protrusion 17, a locking pin 18 is slidably installed in the vertical sliding hole, and a plurality of locking sockets are evenly provided on the circumferential side of the adjusting dial 14, and the bottom end of the locking pin 18 extends into one of the locking sockets. The advantage of such a setting is that when the locking pin 18 is pulled upward to move out of the locking socket, the adjusting dial 14 can be unlocked, and when the locking pin 18 is moved downward to move into the locking socket, the adjusting dial 14 can be locked and cannot rotate, so that during use, the placing table 3 and the rim can be kept in a fixed state and cannot rotate automatically, and the stability is good during use.

[0028] In this embodiment, a limiting iron sheet 19 is fixedly sleeved on the locking pin 18, and a fixed magnet 20 adapted to the limiting iron sheet 19 is fixedly installed on the bottom of the fixed protrusion 17. The advantage of this arrangement is that when the locking pin 18 is pulled upward to unlock the adjustment dial 14, the limiting iron sheet 19 will be driven to move upward together. At this time, under the magnetic force of the fixed magnet 20, the limiting iron sheet 19 will be attracted and fixed, so that the adjustment dial 14 can always remain unlocked, which is more convenient to use.

[0029] As a preferred implementation of this embodiment, a mounting groove matched with the connecting column 6 is provided on the top of the movable arm 5, a rod sliding hole connected with the mounting groove is provided on the side of the movable arm 5, a fixed rod 22 is slidably installed in the rod sliding hole, a fixed plug hole is provided on the side of the connecting column 6, one end of the fixed plug rod 22 passes through the fixed plug hole, and a control pull block 21 is fixedly installed on the other end of the fixed plug rod 22, and an elastic reset unit is installed on the control pull block 21. The advantage of such a setting is that when the control pull block 21 is moved, the fixed plug rod 22 will be driven to move in or out of the fixed plug hole, and then the connecting column 6 can be fixed or loosened, thereby achieving the purpose of facilitating the disassembly, assembly and replacement of the connecting column 6, the inner wall abutment plate 7 and the outer wall abutment plate 8, and the practicality is better.

[0030] In this embodiment, the elastic reset unit includes a reset spring 23 sleeved on the fixed plug rod 22, and the two ends of the reset spring 23 are respectively fixedly mounted on the side of the movable arm 5 and the control pull block 21. The advantage of this arrangement is that when the control pull block 21 is released, the elastic force of the reset spring 23 will pull the control pull block 21 to automatically reset, and then the fixed plug rod 22 can be automatically inserted into the fixed plug hole, and the connecting column 6 can be automatically fixed, and the fixed state can be maintained all the time, which is stable and reliable.

[0031] As a preferred implementation of this embodiment, the inner wall abutment plate 7 and the outer wall abutment plate 8 are both fixed with anti-skid pads on the sides away from each other. The advantage of such an arrangement is that the friction between the inner wall abutment plate 7, the outer wall abutment plate 8 and the wheel rim can be effectively increased by the arrangement of the anti-skid pads, making it more stable when tightly fixed.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
