[0033] The top of the front strut lower bracket 2 is provided with two fork arm holes 21, and the bottom is provided with a stabilizer bar mounting hole 22. Between the fork arm holes 21 and the stabilizer bar mounting hole 22, there are a shock absorber locking hole 23 and a shock absorber mounting hole 24. There is a certain gap between the shock absorber locking hole 23 and the shock absorber mounting hole 24. During detection, the position tolerance shim 8 is inserted into this gap to accurately measure the deviation between the actual position and the theoretical position of the shock absorber locking hole 23 and the shock absorber mounting hole 24, improving the detection accuracy.

[0034] Furthermore, the pressing mechanism 4 includes a pressing bracket 41, a connecting groove 42, a pressing head 43, and a lifting component 44. The pressing bracket 41 is fixedly installed on the inspection table 1. The top of the pressing bracket 41 is rotatably installed with the connecting groove 42. The pressing head 43 is slidably installed on the connecting groove 42. The pressing head 43 presses against the front strut lower bracket 2. The lifting component 44 is used to lift the pressing head 43 to press downwards. Multiple pressing mechanisms 4 can be provided according to actual pressing needs.

[0035] Specifically, a screw rod 16 is fixedly installed above the pressing head 43. The screw rod 16 is threadedly connected to a clamping plate 17 clamped on both sides of the connecting groove 42. The screw rod 16 penetrates through the clamping plate 17 and the position of the clamping plate 17 is fixed by a nut 18.

[0036] To meet the actual pressing needs, an extension plate 19 can also be fixedly installed on the connecting groove 42.

The rotation of the linkage plate 442 further drives the upward movement of the connecting groove 42, so that the pressing head 43 can be lifted, and then the pressing is released; since there is a protrusion 12 at the front end of the linkage plate 442, the protrusion 12 can achieve a good limiting and pressing effect, applying a downward pressure to the pressing head 43, and the pressing effect is good.

[0040] Further, the sliding mechanism 9 includes a sliding bracket 91, an extension rod 92 and a plug rod 93. The sliding bracket 91 is fixedly installed on the inspection table 1.

A position degree plug 8 is fixedly installed at the front end of the extension rod 92.

[0041] Further, a limit seat 13 is fixedly installed at one end of the extension rod 92 away from the position degree plug 8. The setting of the limit seat 13 can prevent the extension rod 92 from detaching from the connecting seat 20 when sliding along the connecting seat 20 on the top of the sliding bracket 91, and the limiting effect is good.
