The multiple groups of dial indicators 18 are respectively fixedly connected to the front ends of the multiple groups of adjustment seats 26 and the other side of the bearing seat 15. The adjusting seat 26 plays the role of adjusting the dial indicator 18. A fixed block 27 is fitted and penetrated at the upper rear edge of the adjusting seat 26. The fixed block 27 fits and penetrates the upper and lower end surfaces of the extending frame 19. A pressure head 31 is fixedly installed at the lower end of the fixed block 27. The fixed block 27 plays a role in ensuring that the pressure head 31 moves vertically up and down, and the pressure head 31 is pressed tightly against the upper end surface of the fixed plate 21.

[0033] The upper and lower end surfaces of the extending frame 19 are penetrated by a through slot 38, and the fixing block 27 is fitted into the inside of the through slot 38.

The tightening spring 28 can press the pressure head 31 onto the fixed plate 21.

[0035] During damage identification detection, the base 43 of the driving mechanism 34 is placed on the top seat 9 and the connecting frame 11. At this time, the four groups of threaded columns 7 are passed through the mounting holes on the base 43 for positioning, so that the driving shaft of the driving mechanism 34 can be located directly below the dial indicator 18. Then the threaded cap 42 is placed on the threaded column 7 and tightened. During the tightening process, the reset spring 41 will shrink and the top seat 9 will move downward, thereby driving the No. 2 gear plate 23 to move downward, so as to drive the No. 2 gear 24 engaged on the No. 2 gear plate 23 to rotate, thereby driving the connecting rod 25 to rotate. The rotating connecting rod 25 drives the No. 1 gear 29 to rotate, thereby driving the No. 1 gear plate 22 engaged on the No. 1 gear 29 to move downward, thereby driving the carrier 3 to move downward. At this time, the dial indicator 18 first presses On the drive shaft, the guide wheel 17 is then pressed onto the drive shaft to keep the position of the dial indicator 18 stationary, so that the dial indicator 18 is in full contact with the drive shaft, that is, the dial indicator 18 is kept in normal use, and then the threaded cap 42 is continued to be tightened to press the base 43 against the top ring 8 for locking and fixing. At this time, the carrier 3 continues to move down to the lowest position. When the carrier 3 continues to move down, the dial indicator 18 will remain stationary. At this time, the spring body 14 is deformed to offset the downward force of the carrier 3. Then the drive mechanism 34 is driven to make the drive shaft rotate slowly, and the dial indicator 18 pressed on the drive shaft is observed to detect whether the shaft runout of the drive shaft is within the normal range, that is, to achieve the purpose of damage identification.
