A screw rod 24 is threadedly connected inside the third thread groove 23. One end of the screw rod 24 extends into the marking block 22 and is connected with a friction block 25. The other side of the marking block 22 is fixedly connected with a measuring rod 26. The other end of the screw rod 24 extends to the outside of the marking block 22 to facilitate reading the scale at the position where the marking block 22 is located.

[0024] Embodiment 2

[0025] Please refer to Figure 1 、 Figure 2 and Figure 4 As shown in, the present utility model provides a technical solution: One side of the rotating frame 9 is fixedly connected with a fixed box 12. A rotating cavity 17 is opened inside the fixed box 12. One end of the rotating rod 10 extends into the rotating cavity 17 and is rotatably connected with one side of the inner cavity of the rotating cavity 17, so that the level of the scale 19 can be adjusted through the rotating rod 10. A driving groove 13 is opened inside the fixed box 12 and on one side of the rotating cavity 17. A bidirectional ball screw 14 is rotatably connected inside the driving groove 13. Moving blocks 15 are threadedly connected to positions on the outer side of the bidirectional ball screw 14 where the thread directions are opposite. One ends of the moving blocks 15 all extend into the rotating cavity 17 and are fixedly connected with friction sleeves 16. The inner sides of the friction sleeves 16 are all in contact with the outer side of the rotating rod 10, so as to limit the positions of the rotating rod 10, the connecting block 11 and the scale 19 by matching the friction sleeves 16 with the friction pads on the outer side of the rotating rod 10. The top end of the bidirectional ball screw 14 extends above the fixed box 12, which is convenient for the operator to rotate the bidirectional ball screw 14, so as to drive the moving blocks 15 and the friction sleeves 16 to move through the bidirectional ball screw 14.

[0026] In summary, when using the vehicle suspension measuring device, the user determines the number of screws on the vehicle wheel hub as required, takes the insertion block 3 provided on the sleeve 4 corresponding to the number of wheel hub screws, and inserts it into the slot 2 corresponding to the wheel hub screw hole. Then, the operator screws the first screw 7 in the first thread groove 6 into the second thread groove 8 to fix the insertion block 3 and the sleeve 4 on the limit plate 1. Then, the bolt 5 is screwed into the screw hole on the vehicle wheel hub. Then, the scale 19 is inserted into the connecting block 11. Then, the second screw 20 is turned, and one end of the second screw 20 passes through the scale 19 and penetrates out of one side of the connecting block 11. Then, the nut 21 is screwed on the outside of the second screw 20. By checking the universal level bubble installed on the top of the scale 19, the levelness of the scale 19 is adjusted. After adjusting the levelness of the scale 19, the operator rotates the bidirectional ball screw 14, so that the bidirectional ball screw 14 drives the moving block 15 and the friction sleeve 16 to move, so that the inner side of the friction sleeve 16 contacts the outer side of the rotating rod 10. Through the cooperation of the friction pad provided on the outer side of the friction sleeve 16 and the rotating rod 10, the position of the scale 19 is limited. Then, the marking block 22 is driven to move on the scale 19 until the measuring rod 26 on the marking block 22 contacts the air suspension frame. At this time, the screw 24 is tightened to fix the marking block 22 on the scale 19, and the scale value at the position where the marking block 22 is located is read. The scale value is the distance between the center of the wheel hub and the air suspension. When disassembly is required, the nut 21 is unscrewed from the outside of the second screw 20, then the second screw 20 is taken out from the scale 19 and the connecting block 11, then the scale 19 is taken out from the connecting block 11, and then the bolt 5 is unscrewed from the vehicle wheel hub screw hole, so as to remove this measuring device from the vehicle wheel hub.
