When the transverse distance between the guide plates needs to be adjusted, the extrusion slide plate 26 can slide towards the inner wall of one side of the switch box 12 by virtue of the support slide plate 27, when the guide plates on two sides need to slide close or separate at the same time, the extrusion slide plate 26 compresses the support spring 31 and slides downwards relative to the support slide plate 27, then slides towards the inner wall of one side of the switch box 12, the extrusion slide plate 26 can simultaneously extrude and act on the first extension control pressure switch 37 and the second extension control pressure switch 38 or simultaneously extrude and act on the first extension control pressure switch 24 and the second extension control pressure switch 25, so that the hydraulic telescopic rods 11 in the two groups of support assemblies synchronously contract or elongate, so that the guide plates transversely synchronously move oppositely, and the distance is adjusted, and if only one guide plate needs to transversely move relative to the other guide plate on one side, the extrusion slide plate 26 does not need to be pressed downwards, and only the extrusion slide plate 26 directly transversely moves on the corresponding first extension control pressure switch 37 or the first extension control pressure switch 24;
When the extrusion slide plate 26 transversely moves to extrude the first pressure sensing switch group or the second pressure sensing switch group on the side wall each time, the extrusion slide plate 26 can be extruded to act on the first pressure switch piece 32, the first pressure switch piece 32 enables the electric telescopic rod 21 to retract, the pressing plate 22 is separated from the synchronous belt 6, the synchronous belt 6 is restored to a state capable of being rolled or stretched, when the transverse interval between the two side guide plates is adjusted, the synchronous belt 6 is influenced, the synchronous belt 6 can be pulled out from the rolling cylinder 19 for one section, or the winding column 20 rolls up a part of the synchronous belt 6 by means of coil spring resilience, so that the length of the synchronous belt 6 is synchronously adjusted along with the transverse interval adjustment of the two side guide plates, after the transverse interval adjustment of the two side guide plates is finished, the extrusion slide plate 26 can be slid back to reset under the resilience force of the limit spring 29, the second pressure switch piece 33 enables the electric telescopic rod 21 to be stretched, the synchronous belt 6 is re-pressed by the pressing plate 22, and the synchronous belt 6 can enable the two side transmission shafts 5 to synchronously rotate in pairs by means of the pressing plate 22, and the longitudinal interval between the first guide plates 7 and the second guide plates 8 can be continuously adjusted.
