[0024] The following is a detailed description of the specific settings and functions of this embodiment. When in use, the tire edge is first separated from the wheel hub, and the tire is disassembled and transported using the cart. When disassembling, the pry bar 12 is first pressed against both sides of the bottom of the wheel to make one side of the triangular baffle 2 abut against the tire, and then the end of the Z-shaped plate 23 equipped with the limit plate 29 is rotated along the rotating shaft 21 to be close to the tire. At this time, the middle turning point of the Z-shaped plate 23 will abut against the edge of the tire, and then the lever 26 is driven along the slide groove 24 to drive the slide plate 25 to the rotating shaft 2 with the socket 22. 1 until the insertion rod 27 is inserted into the insertion hole 22, which can fix the angle of the Z-shaped plate 23 and the limit plate 29 at the end. Finally, the limit plate 29 is pulled out so that one end is stuck on the other side of the tire. The tire is fixed by the triangular baffle 2, the turning point of the Z-shaped plate 23, the pry bar 12 and the limit plate 29. The push rod 11 can be pressed to lift the end with the pry bar 12, so that the tire can be removed and pushed to the maintenance place. The lever principle makes it easier for the staff to remove the tire and load it.

[0025] Example 2, as Figure 1 、 Figure 2 and Figure 3 As shown, a cross bar 15 is fixedly installed in the middle of the frame 1, one side of the two triangular baffles 2 is fixedly connected to the cross bar 15 respectively, a support pulley 14 is fixedly connected to the lower middle part of the cross bar 15, both sides of one end of the frame 1 are fixedly connected to the pry bar 12, both sides of the middle of the other end of the frame 1 are fixedly installed with a push rod 11, and both sides of the middle of one end of the frame 1 are fixedly installed with a movable pulley 13, and the two movable pulleys 13 are respectively located on both sides of the two pry bars 12.

[0026] The effect achieved by the entire embodiment is that when in use, the edge of the tire is first separated from the wheel hub, and the tire is disassembled and transported using the cart. When disassembling, the pry bar 12 is first pressed against both sides of the bottom of the wheel to make one side of the triangular baffle 2 abut against the tire, and then the end of the Z-shaped plate 23 equipped with the limit plate 29 is rotated along the rotating shaft 21 until it is close to the tire. At this time, the middle turning point of the Z-shaped plate 23 will abut against the edge of the tire, and then the lever 26 is moved along the slide groove 24 to drive the slide plate 25 to the position where the socket 22 is provided. The rotating shaft 21 moves until the insertion rod 27 is inserted into the insertion hole 22, which can fix the angle of the Z-plate 23 and the limit plate 29 at the end. Finally, the limit plate 29 is pulled out so that one end is stuck on the other side of the tire. The tire is fixed by the triangular baffle 2, the turning point of the Z-plate 23, the pry bar 12 and the limit plate 29. By pressing the push rod 11, the end equipped with the pry bar 12 can be tilted, thereby removing the tire, and then it can be pushed to the maintenance site through the push rod 11 and the movable pulley 13.

[0027] The method of use and working principle of this device are as follows: when using, first separate the edge of the tire from the wheel hub, and then use the cart to disassemble and transport the tire. When disassembling, first press the pry bar 12 against both sides of the bottom of the wheel to make one side of the triangular baffle 2 abut against the tire, and then rotate the end of the Z-shaped plate 23 equipped with the limit plate 29 along the rotating shaft 21 until it is close to the tire. At this time, the middle turning point of the Z-shaped plate 23 will abut against the edge of the tire, and then move the lever 26 along the slide groove 24 to drive the slide plate 25 to move toward the rotating shaft 21 where the plug hole 22 is opened until the rod 2 is inserted. 7 is inserted into the socket 22, which can fix the angle of the Z-shaped plate 23 and the limit plate 29 at the end. Finally, the limit plate 29 is pulled out so that one end is stuck on the other side of the tire. The tire is fixed by the triangular baffle 2, the turning point of the Z-shaped plate 23, the pry bar 12 and the limit plate 29. By pressing the push rod 11, the end with the pry bar 12 can be tilted up, so that the tire can be removed and then pushed to the maintenance place by the push rod 11 and the movable pulley 13. The lever principle makes it easier for the staff to remove the tire and load it.
