[0031] When the two dual-axis motors 3 are running, the four rotating shafts 4 will drive the four rotating rods 5 to rotate, and then the four circular shafts 6 will rotate and squeeze to drive the four rectangular blocks 7 to rotate, so that the four rotating blocks 8 will drive the four circular wheels 10 to rotate with the movable shaft 9 as the axis.

[0032] Among them, the left and right sides of the top of the rectangular plate 1 are fixedly connected with fixed plates 11, the number of fixed plates 11 is two, the tops of the two fixed plates 11 are fixedly connected with a workbench 12, the inside of the workbench 12 is fixedly connected with a limiting plate 13, the outer surface of the limiting plate 13 is movably connected with a splint 14, the number of splints 14 is two, and the outer surfaces of the two splints 14 are movably connected to the inner surface of the workbench 12.

[0033] The design of the limiting plate 13 serves to limit the two clamping plates 14 .

[0034] The top of the rectangular plate 1 is fixedly connected with a driving motor 15 located between the two fixing plates 11 , and the other end of the output shaft of the driving motor 15 is fixedly sleeved with a lead screw 16 , and the other end of the lead screw 16 is movably connected to the inner side of the fixing plate 11 .

[0035] When the driving motor 15 is running, the lead screw 16 will rotate.
