[0003] In the prior art, a person first places the tire on the bottom plate so that the tire is aligned with the rubber column, and then the person moves the hub and places the hub on the upper end of the tire. The person uses two fingers to fix the hub, and then the person moves the rotary handle to make the extrusion device extrude the hub into the tire. Since there is no limiting device on the bottom plate, when the person places the tire and the hub, most of the time, the person judges whether the placement positions of the tire and the hub are directly below the rubber column by eyes.

The sliders drive the compression springs to contract. Then the person moves the hub body so that the hub body is located between the two extrusion plates. Then the person releases the pull rings. At this time, the compression springs rebound and drive the sliders to move toward the hub body. The sliders drive the extrusion plates to move toward the hub body until the two extrusion plates abut against the hub body. At this time, the person moves the rotary handle downward so that the extrusion device moves downward. The extrusion device drives the rubber column to move downward. The rubber column will first abut against the hub body during the downward movement and then drive the hub body to move downward. The hub body drives the two extrusion plates to move downward. The extrusion plate is a PVC plate. The PVC plate has good wear resistance and relatively high strength and is not easily worn significantly during short-term use. The extrusion plate drives the slider to move downward. The slider drives the adjusting block to move downward. The adjusting block drives the connecting rod and the protective pad to move downward. The connecting rod slides on the inner wall of the connecting groove. The protective pad can protect the adjusting block and the positioning plate and prevent direct contact between the upper surface of the adjusting block and the positioning plate when the spring rebounds and drives the adjusting block to move. Then the adjusting block drives the spring to contract. The adjusting block slides on the arc surface of the limiting rod. The limiting rod can limit the adjusting block and prevent the adjusting block from being misaligned when sliding on the inner wall of the connecting groove. When the hub body contacts the tire, the person moves the rotary plate downward again. At this time, the hub body slides on the side where the two extrusion plates are close to each other until the hub body slides into the interior of the tire. At this time, the person moves the moving plate upward. The moving plate drives the moving disk to move upward. The moving plate drives the assembled hub body and tire to move upward until the hub body and tire slide out of the inner wall of the moving disk. The anti-slip grooves formed on the lower surface of the moving plate can increase the friction between the person's hand and the moving plate and prevent the person from slipping when moving the moving plate. By setting the limiting structure,It has achieved the ability to conveniently position the tires and wheel hubs of the car model by personnel quickly, thereby improving the work efficiency of personnel.

[0027] Working principle: When assembling the wheel hub body 7 of the car model, the operator first places the tire 8 on the bottom plate 1 so that the tire 8 faces the rubber column 6. Then the operator moves the wheel hub body 7 and places it on the upper end of the tire 8. The operator then uses two fingers to fix the wheel hub body 7. Next, the operator moves the rotary handle 4 downward, and the rotating plate drives the extrusion device 3 to move downward. The extrusion device 3 drives the rubber column 6 to move downward until the rubber column 6 abuts against the wheel hub body 7 and drives the wheel hub body 7 to move downward until the wheel hub body 7 slides into the interior of the tire 8. When the operator needs to assemble the wheel hub body 7, the operator can first slide the tire 8 into the inner wall of the limiting groove 502. Then the operator moves the two pull rings 516 so that the two pull rings 516 move away from each other. The two pull rings 516 drive the connecting rods 515 to move away from each other respectively. The pull ring 516 can facilitate the operator to move the connecting rod 515 and improve the operation convenience of the operator. Then the two connecting rods 515 drive the sliders 519 to move away from each other respectively. The two sliders 519 drive the extrusion plates 512 to move away from each other respectively. The slider 519 drives the compression spring 517 to contract. Then the operator moves the wheel hub body 7 so that the wheel hub body 7 is located between the two extrusion plates 512. Then the operator releases the pull ring 516. At this time, the compression spring 517 rebounds and drives the slider 519 to move towards the wheel hub body 7. The slider 519 drives the extrusion plate 512 to move towards the wheel hub body 7 until the two extrusion plates 512 abut against the wheel hub body 7. At this time, the operator moves the rotary handle 4 downward to make the extrusion device 3 move downward. The extrusion device 3 drives the rubber column 6 to move downward. The rubber column 6 will first abut against the wheel hub body 7 during the downward movement and then drive the wheel hub body 7 to move downward. The wheel hub body 7 drives the two extrusion plates 512 to move downward. The extrusion plate 512 is a PVC plate. The PVC plate has good wear resistance and large strength and is not easily worn significantly during short-term use. The extrusion plate 512 drives the slider 519 to move downward. The slider 519 drives the adjusting block 510 to move downward. The adjusting block 510 drives the connecting rod 515 and the protective pad 518 to move downward. The connecting rod 515 slides on the inner wall of the connecting groove 508. The protective pad 518 can protect the adjusting block 510 and the positioning plate 507 and prevent the upper surface of the adjusting block 510 from directly contacting the positioning plate 507 when the spring 513 rebounds and drives the adjusting block 510 to move.

The limiting rod 511 can limit the adjusting block 510 and prevent the adjusting block 510 from being misaligned when sliding on the inner wall of the connecting groove 509. When the wheel hub body 7 contacts the tire 8, the operator moves the rotating plate downward again.At this time, the hub body 7 will slide on the side where the two pressing plates 512 are close to each other until the hub body 7 slides into the interior of the tire 8. At this time, the operator moves the moving plate 505 upward. The moving plate 505 drives the moving disk 504 to move upward. The moving plate 505 drives the assembled hub body 7 and the tire 8 to move upward until the hub body 7 and the tire 8 slide out of the inner wall of the moving disk 504. The anti-slip grooves 506 formed on the lower surface of the moving plate 505 can increase the friction between the operator's hand and the moving plate 505, preventing the operator from slipping when moving the moving plate 505. By providing the limiting structure 5, it is convenient for the operator to quickly position the tire 8 and the hub body 7 of the car model, thereby improving the working efficiency of the operator.
