by arranging the first loop bar and the second loop bar, when a user utilizes the lifting adjusting mechanism for bus maintenance to fix buses, the user can rotate the first nuts at the two ends of the telescopic clamp arm according to the diameter of a wheel, so that the first nuts drive the two groups of first loop bars between the lifting clamp and the telescopic clamp arm to rotate, thereby drawing out the first loop bar, thereby adjusting the distance between the two groups of telescopic clamp arms, simultaneously, the second nuts at one end of the telescopic clamp arm are rotated according to the width of the wheel, so that the second nuts drive the second loop bars in the telescopic clamp arm to rotate, the second loop bar is drawn out by utilizing the thread structure between the second loop bar and the telescopic clamp arm, the size of the arc-shaped clamp groove on the telescopic clamp arm is adjusted, and the wheel fixing size of the lifting clamp can be adjusted by utilizing the arrangement of the first loop bar and the second loop bar, thereby the lifting adjusting mechanism can be suitable for buses with different models, the lifting adjusting mechanism for bus maintenance has a fixed adjusting structure, so that the application range of the lifting adjusting mechanism is widened;
through setting up the side fagging, when the user utilizes this bus to maintain and carry out the vehicle lifting operation with lift adjustment mechanism, the user can utilize the dwang to rotate the side fagging, take the side fagging out from fixed foot rest, rotate simultaneously and twist and tie admittedly, make and loosen between side fagging and the rotatory cardboard, utilize the draw-in groove of rotatory cardboard to rotate rotatory cardboard, press down rotatory cardboard, make the rubber pad top of rotatory cardboard subaerial, it is fixed to rotate to twist to tie admittedly and lock between side fagging and the rotatory cardboard, utilize the rotatory cardboard of side fagging cooperation to carry out the auxiliary stay to this lift adjustment mechanism's bottom, avoid it to appear the slope phenomenon at the vehicle lift in-process, promote its stability.
