The utility model discloses technical scheme that child arm adopted is torn open to double-end tire is, including the slide bar with set up two dish wheels in slide bar one end from top to bottom, still including setting up bedplate behind dish wheel one side and slide bar vertical fixation's pinch roller, bedplate outer end sets up the pinch roller that stands side by side with the dish wheel behind the pinch roller.

The utility model relates to a preferred embodiment is, the base plate is the bent plate of outer end to dish wheel one side bending behind the pinch roller, and crooked angle alpha is 25-35.

Further, the bending angle alpha of the pinch roller rear seat plate is 30 degrees.

Further, the pinch roller is a tapered roller.

Still further, the pinch roller is rotatably connected with the pinch roller rear seat plate through a pinch roller shaft.

The utility model relates to a preferred embodiment is, two the dish wheel passes through dish wheel axle rotatably with sliding rod connection.

Furthermore, an included angle beta is formed between the two dish wheels, and the included angle beta is 40-45 degrees.

The utility model discloses a preferred embodiment is, the slide bar is hexagonal.

The utility model relates to a tire detacher adopts the technical scheme that, tire detacher adopts above-mentioned double-end tire to detach child arm.

The utility model has the advantages that: the tire disassembling arm of the double-head tire disassembling machine is of a double-head structure of a disc wheel and a pressing wheel, tire bead openings are pressed through the double disc wheels and the pressing wheel, a symmetrical surface between the two disc wheels and an axial surface of the pressing wheel are the same plane, when the tire is disassembled and assembled, the disc wheels firstly apply pressure to the tire bead openings to enable the tire bead openings to be preliminarily separated, and the pressing wheel further rolls the tire bead openings to enable the tire bead openings to be completely separated from a rim and cannot be rebounded. And the bending angle of the pressing wheel rear seat plate, the conical shape of the pressing wheel and the angle design between the two disc wheels are adopted, so that the effect of disassembling and assembling the wheel type amphibious armored vehicle tire is better, the tire can be prevented from being damaged, and the efficiency of disassembling and assembling the tire is high.
