As a preferred embodiment of the invention, the section of the fixing ring 2 is C-shaped, and the invention prefers the C-shaped fixing ring 2, and the opening of the C-shaped fixing ring 2 faces the direction of the steel plate conveying roller way. In the present invention, the C-shaped fixing ring 2 is only one convenient and most suitable embodiment, but the present invention is not limited thereto, and the shape of the fixing ring 2 is not limited to the C-shape.
The chute 3 is disposed in the fixing ring 2. As a matching component with the above embodiment, the cross section of the chute 3 is also preferably C-shaped, that is, the invention preferably selects the C-shaped chute 3 and can rotate in the C-shaped fixed ring 2, the opening of the C-shaped chute 3 is parallel to the steel plate rollgang, and the opening of the C-shaped chute 3 faces the steel plate rollgang direction.
Three sliders 5 are arranged in the C-shaped sliding chute 3 and respectively comprise a left slider 51, a right slider 52 and a middle slider 53, the left slider 51 and the right slider 52 are connected through a connecting rod 8, the middle slider 53 is provided with a through hole at the position corresponding to the connecting rod 8, and the connecting rod 8 passes through the through hole. The distance between the center position of the left slide block 51 and the center position of the right slide block 52 is 2.4 meters, a positioning bayonet is arranged on the connecting rod 8 at the position 1.6 meters between the center position of the left slide block 51 and the center position of the middle slide block 53, and a positioning bayonet is also arranged on the connecting rod 8 at the position 1.6 meters between the center position of the right slide block 52 and the center position of the middle slide block 53. In a preferred embodiment of the present invention, the connecting rod 8 is metal.
