[0039] Embodiment 2:

[0040] On the basis of Embodiment 1, its specific working principle is as follows:

[0041] This anti-slip coefficient detector combines the central substrate 10 and the side substrate 11 to form a sliding plate assembly. First, install the two on the outside of the mounting base 13 so that the ends of the central substrate 10 with through holes are in contact with each other. At the same time, energize the electromagnet so that the electromagnet adsorbs the central substrate 10 on the outside of the mounting base 13. Since there is a certain slope on the inner side of the limit block 14 and there are also slopes on both sides of the mounting base 13, during the process of installing the central substrate 10 on the outside of the mounting base 13, the sloped side of the limit block 14 will be in contact with both sides of the mounting base 13, so that when the central substrate 10 approaches the mounting base 13, the position of the central substrate 10 is automatically adjusted by the sliding of the two limit blocks 14 on both sides of the mounting base 13. Furthermore, the central substrate 10 and the side substrate 11 are automatically combined and installed inside the mounting base 13 to form a sliding plate assembly. During the combined installation process, only the single central substrate 10 or side substrate 11 needs to be carried, preventing inconvenience in carrying due to the excessive weight of the parts;

[0042] After the central substrate 10 and the side substrate 11 are combined and installed to form a sliding plate assembly, at this time, start the hydraulic rod 4 to drive the clamping seat 8 to slide inside the positioning rod 7 through a plurality of positioning sleeves 9 until the two clamping seats 8 respectively clamp and fix the mutually remote ends of the two central substrates 10. Then, cut off the power supply of the electromagnet and start the telescopic rod 6 to drive the moving plate 12 to move, so that the mounting base 13 drives the electromagnet away from the central substrate 10 and the side substrate 11;

[0043] After the central substrate 10 and the side substrate 11 are combined and installed to form a sliding plate assembly, it is necessary to install the bolt 15 inside the through holes inside the central substrate 10 and the side substrate 11. Start the telescopic rod 6 to drive the moving frame 23 away from the central substrate 10, install the bolt 15 inside the sensor 24, so that the head of the bolt 15 is magnetically attracted to the magnetic ring 25. At this time, drive the moving frame 23 to drive the bolt 15 to approach the central substrate 10 and the side substrate 11 through the telescopic rod 6 until the bolt 15 is installed inside the through holes of the central substrate 10 and the side substrate 11;

[0044] When the bolt 15 is installed inside the through holes of the central substrate 10 and the side substrate 11, install the gasket 17 at one end of the bolt 15 away from its head. Start the telescopic rod 6 to drive the clamping seat 8 to drive the screw sleeve 21 away from the central substrate 10 and the side substrate 11, install the nut 16 inside the nut 16. When all the nuts 16 are installed, at this time, drive the drive shaft 19 to rotate inside the motion box 18 through the rotation of the motor, so that the drive shaft 19 drives the bevel gear ring 20 to rotate. Furthermore, drive the driven bevel gear 22 to rotate through the rotation of the bevel gear ring 20, and drive the screw sleeve 21 and the nut 16 inside it to rotate through the rotation of the driven bevel gear 22. During the rotation of the nut 16, drive the screw sleeve 21 and the nut 16 to approach the bolt 15 through the telescopic rod 6, so as to install the nut 16 at the end of the bolt 15, realizing the automatic installation of the bolt 15.
