The left base 1 and the right base 2 are also provided with a plurality of pin storage devices 11, a tooling box 12, a marking pin 13, a detection pin 14 and a dial indicator 15. When the inspection fixture is used, the shock absorber tower is firstly placed on the support component 3, and then the shock absorber tower is fixed by the positioning component 4. Then the detection component 5 is pressed against each surface of the shock absorber tower. Finally, the marking pin 13, the detection pin 14 and the dial indicator 15 are used to inspect the hole position and size of the shock absorber tower. The marking pin 13 is used to determine the position deviation of the shock absorber tower hole, and the detection pin 14 is used to detect the position and size of the shock absorber tower hole.
