[0025] See also Figure 4 , is a schematic diagram of the structure of a vehicle brake drum, the brake drum 100 is used to be installed on the axle, and a plurality of screws 101 for installing wheels are installed on one side of the brake drum 100.

[0026] See also Figure 1-3 A vehicle brake drum disassembly auxiliary device includes a horizontal jack 10, a support platform 20, a traction rod 30 and a fixing ring 40. The support platform 20 is installed on the lifting arm 11 of the horizontal jack 10. One end of the traction rod 30 is connected to the horizontal jack 10, and the other end is installed with a fixing ring 40. The brake drum 100 is supported by the support platform 20, and the fixing ring 40 is sleeved on a screw rod 101 on the lower side of the brake drum 100 and then a nut is installed on the screw rod 101. The device has a simple connection method and is more convenient to use.

[0027] Horizontal jack 10 is a finished product purchased from the market.

[0028] In one solution, the support platform 20 is an arc-shaped groove.

[0029] In another embodiment, the support platform 20 is a flat plate, and two ends of the support platform 20 are connected to side panels 21 .

[0030] See also Figure 1 , 2 A connecting rod 12 is installed on the horizontal jack 10, a rotating sleeve 13 is movably installed on the connecting rod 12, and one end of the traction rod 30 connected to the horizontal jack 10 is connected to the rotating sleeve 13. Through the above structure, the connecting rod 12 is convenient for swinging.

[0031] exist Figure 2 In the embodiment, the length of the rotating sleeve 13 is smaller than the length of the connecting rod 12 between the two side walls of the horizontal jack 10, so that the rotating sleeve 13 can move axially along the connecting rod 12 to adjust the position.

[0032] Furthermore, a hinge seat 31 is installed at one end of the traction rod 30 connected to the fixing ring 40, a hinge block 41 is fixed to the fixing ring 40, and the hinge seat 31 and the hinge block 41 are hinged via a pin 32. With the above structure, when the ground is uneven, it is convenient to adjust the angle of the fixing ring 40 so that the screw rod 101 can easily enter the fixing ring 40.
