[0002] When buses need to replace or repair tires, a tire changer is needed to remove the tires from the rims. Existing tire changers are fixed in position, and the workbench is about 1.2 meters high. Bus tires are usually 275 / 70R22.5, 11R22.5, etc., and a single tire (including the rim) can weigh 50-80kg, far exceeding the weight of ordinary car tires. Therefore, unloading the tires from the bus, transporting them to the tire changer, and then lifting them onto the workbench is time-consuming, laborious, and very inconvenient.

A motor and a right-angle reducer are located at the bottom of the base, with the output end of the motor connected to the reducer. The base has a hub positioning hole and a fixed cylinder. A transmission device is located inside the fixed cylinder and connected to the output end of the reducer. The transmission device is also connected to a crossbar, which is connected to a bird's head.

[0005] Furthermore, the transmission device is a first transmission sleeve, which is connected to the output end of the right-angle reducer, and the crossbar is provided with a first transmission shaft corresponding to the first transmission sleeve.

[0006] Furthermore, the crossbar is a second transmission sleeve, and the bird head is provided with a second transmission shaft corresponding to the second transmission sleeve.

[0007] Furthermore, the second transmission sleeve is provided with a fixed screw, the fixed screw is provided with two movable nuts, the second transmission shaft is provided with a mounting seat, the mounting seat is provided with a through hole, the fixed screw can pass through the through hole, and the movable nuts are respectively located on both sides of the mounting seat.

[0008] Furthermore, the base is provided with a bracket, the bracket is provided with a telescopic rod, and the telescopic rod is provided with a separation pressure plate.

[0009] Furthermore, the telescopic rod is an electric telescopic rod or a pneumatic telescopic rod.

[0010] Compared with the prior art, the advantages of this utility model are: the tire changer has wheels at the bottom, which can be easily pulled to any position, reducing the time spent moving tires; the base is low to the ground, making it easy to lift the tires up, reducing the time spent moving them.

[0015] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] A portable tire changer includes a base 1, wheels 2 at the bottom of the base 1, a movable handle 3, a motor 4 and a right-angle reducer 5 at the bottom of the base 1, the output end of the motor 4 being connected to the right-angle reducer 5, a hub positioning hole 6 and a fixed cylinder 7, which can be configured with multiple sets of hub positioning holes 6 with different diameters and positions to accommodate tires of various sizes, a transmission device inside the fixed cylinder 7, the transmission device being connected to the output end of the right-angle reducer 5, the transmission device being connected to a crossbar 8, the crossbar 8 being connected to a bird head 9, the transmission device being a first transmission sleeve 10, the first transmission sleeve 10 being connected to the output end of the right-angle reducer 5, the crossbar 8 having a first transmission shaft 11 corresponding to the first transmission sleeve 10, the crossbar 8 being a second transmission sleeve 12, and the bird head 9 having a second transmission shaft 13 corresponding to the second transmission sleeve 12.
