When the guide connecting rod 902 swings, the distance between the magnetic shielding plate 903 and the center of the colloid support plate 8 will be changed, so that the magnetic shielding plate 903 slides along the colloid support plate 8 until it slides off the colloid support plate 8. At this time, the positioning magnetic plate 801 is exposed, and the positioning mounting rod 3 is pressed down. The positioning magnetic plate 801 will be adsorbed on the F-shaped steel 1, thereby realizing the connection between the F-shaped steel 1 and the colloid support plate 8.
