The lower part of the bearing special-shaped piece 4 is of a hyperboloid structure, and a plurality of inner sliding ways 41 arranged along the height direction are arranged on the outer surface of the bearing special-shaped piece 4. The elastic attaching piece 5 is an arc-shaped component with elasticity, the elastic attaching piece 5 is connected with the sliding block 8 which is arranged in the inner sliding way 41 in a sliding way and is in sliding connection with the bearing special-shaped piece 4 through the sliding block 8, two end parts of the elastic attaching piece 5 are arranged up and down and face the outer side of the bearing special-shaped piece 4, the upper end and the lower end of the elastic attaching piece 5 are connected with the supporting claw 3, the supporting claw A31 is positioned at the lower end, and the supporting claw B32 is positioned at the upper end. At least the supporting claw A31 at the lower end is provided with an electromagnetic chuck structure, and the electromagnetic chuck structure, the electromagnetic switch 6 and the power supply 7 form a loop. The supporting claw B32 may be provided with an electromagnetic chuck structure as required. When the elastic attaching piece 5 is connected with the sliding block 8, the distance between the supporting claw A31 at the lower end and the central line of the bearing special-shaped piece 4 is ensured to be larger than the distance between the supporting claw B32 at the upper end and the central line of the bearing special-shaped piece 4.
