when the detection arm mechanism 3 clings to the flat curved glass for movement detection through the detection wheel 61, the detection wheel 61 loses support along with the change of the rotation angle of the detection arm mechanism 3, and the detection plate 6 loses support, so that the double-end threaded rod 7 moves under the pulling of the conductive ring 71, the resistance wire 33 and the elastic wire-rewinding device 32, namely the detection plate 6 extends out of the plate sleeve 5 and always butts against the surface of the flat curved glass;
