The pressing part 23 can press the wheel disc 201 of the wheel rim 200.

[0037] An acting cylinder 30 is disposed at the connecting portion 11 of the base 10. The acting cylinder 30 has a cylinder body 31 and a movable rod 32. The cylinder body 31 is locked at the connecting portion 11 of the base 10. The movable rod 32 is movably penetrated through the opening 111 of the base 10. The movable rod 32 can be extended and retracted relative to the cylinder body 31. In an embodiment of the utility model, the acting cylinder 30 is a pneumatic cylinder. The end of the movable rod 32 has a thread.

[0038] A disassembly piece 40 is arranged at one end of the movable rod 32. The disassembly piece 40 has a joint portion 41 and an action portion 42. The joint portion 41 is provided with a screw hole 411. The disassembly piece 40 is screwed to the movable rod 32 through the screw hole 411 of the joint portion 41; the action portion 42 is basically in the shape of a curved arc sheet, wherein, when the action cylinder 30 is actuated, the movable rod 32 can drive the disassembly piece 40 to press against the inner edge 301 of the tire 300 so that the tire 300 is detached from the wheel rim 200.

[0039] An adjusting valve 50 is provided on the base 10, and the adjusting valve 50 is located between the connecting portion 11 and the clamping portion 12. The adjusting valve 50 has a pressure gauge 51 and an adjusting knob 52. The adjusting valve 50 is connected in series between the cylinder 30 and a power source 60.

In an embodiment of the utility model, the power source 60 is an air compressor.

[0040] See also Figure 3 and Figure 5 As shown, the action groove 123 of the clamping portion 12 of the base 10 can clamp the wheel disc 201 of the wheel rim 200, and the pressing piece 20 can be screwed relative to the clamping portion 12 according to the thickness of the wheel disc 201, and the pressing portion 23 of the pressing piece 20 presses against the wheel disc 201 to firmly fix the wheel disc 201 in the action groove 123, wherein, since the connecting portion 11 and the clamping portion 12 of the base 10 are located at different horizontal planes, the disassembly piece 40 maintains a certain distance from the tire 300.

[0041] See also Figure 4 and Figure 6 As shown in the figure, after the tire 300 is punctured, the internal gas of the tire 300 is no longer full. Thus, the action of the cylinder 30 can drive the disassembly piece 40 to move toward the inner edge 301 of the tire 300 to press against the inner edge 301. Since the cylinder 30 has a certain output force, the disassembly piece 40 can be driven to press the inner edge 301 of the tire 300 downward and away from the outer flange 202 of the wheel rim 200 without manpower, so that the inner edge 301 of the tire 300 and the wheel rim 200 are aligned. Then, the user can use the long wrench 400 to extend into the opening S, and use the wheel rim 200 as a fulcrum to pry the tire 300 with the wrench 400, pry up the inner edge 301 of the tire 300, and pass over the position of the outer flange 202 of the wheel rim 200, and apply repeated prying actions along the outer flange 202 of the wheel rim 200, and finally remove the tire 300 from the wheel rim 200, so as to facilitate the subsequent tire changing operation.

[0042] Therefore, the disassembly device 100 of the present invention has the advantage of being small in size and can be placed on a vehicle and carried along with the vehicle for emergency use. When a vehicle has a flat tire, it can provide a quick tire change without having to wait for roadside assistance from a repair shop. In addition, during use, the user can complete the tire change operation independently with less effort.

[0043] Moreover, the present invention can quickly fix the base 10 to the wheel disc 201 of the wheel rim 200 through the clamping portion 12 of the base 10 and the pressing piece 20, so as to achieve the effect of fast tire changing with a simple tire changing procedure.
