[0021] Furthermore: in order to facilitate the labor-saving disassembly of the tire 7, the bottom of the extended end of the electric telescopic rod 3 is fixedly connected with a slide plate 8, and both sides of the bottom of the slide plate 8 are provided with a receiving skid 9 used in conjunction with the tire 7, and the bottom of the slide plate 8 is provided with an adjusting mechanism 10 used in conjunction with the receiving skid 9. The adjusting mechanism 10 includes a bidirectional threaded rod 101, and the bidirectional threaded rod 101 is rotatably arranged at the bottom of the slide plate 8 through a bearing. Both sides of the surface of the bidirectional threaded rod 101 are threadedly connected with a threaded drive sleeve 102, and the bottom of the adjacent threaded drive sleeve 102 is fixedly connected to the top of the receiving skid 9, and the bottom of the slide plate 8 is fixedly provided with a second motor 103 through a bracket. The output shaft of the second motor 103 is fixedly connected to one end of the bidirectional threaded rod 101 through a coupling, and sliders 17 are slidably provided on both sides of the inner cavity of the slide plate 8, and the bottom of the slider 17 on the same side is fixedly connected to the top of the threaded drive sleeve 102. As a detailed explanation: the first motor 2 and the second motor 103 are both servo motors.

[0022] Furthermore: in order to facilitate the lifting and hanging of the loose upper part of the tire 7, a lifting frame 11 is provided on one side of the receiving skid frame 9 through a slotted sliding arrangement, and a first threaded rod 12 is provided on the surface of the receiving skid frame 9 through a bearing rotation, and a first threaded sleeve 13 is threadedly connected to the surface of the first threaded rod 12, and one side of the first threaded sleeve 13 is fixedly connected to the side of the lifting frame 11, and a roller 14 is provided on the surface of the lifting frame 11 through a slotted rotation arrangement, and a guide slide hole 15 is provided on the surface of the lifting frame 11, and a guide slide rod 16 that slides and fits with the guide slide hole 15 is fixedly provided on the surface of the receiving skid frame 9.

[0023] When in use, the concentric movement of multiple inward-expanding fixing mechanisms 5 is used in advance to prompt the wheel hub 6 to be fixed on the top of the placement table 4, and then the crowbar is inserted into the gap between the tire 7 and the wheel hub 6, and the crowbar insertion position needs to be close to the receiving pry frame 9. When the tire 7 is partially deformed and tilted to appear a gap that can be inserted, the second motor 103 is started to prompt it to drive the bidirectional threaded rod 101 to rotate. The bidirectional threaded rod 101 rotates, and the threaded driving sleeves 102 on both sides of its surface will respectively carry the two receiving pry frames 9 to move in opposite directions, and finally prompt the two receiving pry frames 9 to be inserted from the tilted gap of the tire 7 to the two sides of the inner cavity of the tire 7. Then the first motor 2 is started to prompt the first motor 2 to drive the placement table 4, wheel hub 6 and tire 7 to rotate. The wheel hub 6 and tire 7 rotate, and the side of the tire 7 that fits the wheel hub 6 is circumferentially tilted to the top of the wheel hub 6 by the receiving pry frame 9;

[0024] After the upper side of the tire 7 is removed, the operator screws the first threaded rod 12, causing the first threaded sleeve 13 on the surface of the first threaded rod 12 to carry the lifting frame 11 to temporarily lift the loose upper half of the tire 7, so that the lower side of the tire 7 is close to the top of the wheel hub 6. Then, the crowbar is used to pry the tire 7 near the top of the wheel hub 6, causing the bottom of the tire 7 to bulge upward to form an insertion gap, and causing the deformed part of the bottom of the tire 7 to hang on the receiving prying frame 9. Then, the first motor 2 is started to drive the placement table 4 and the wheel hub 6, so that the tire 7 can be completely separated from the wheel hub 6.
