For example, the movable processing device is a tractor chuck, one end of the profile is clamped by the tractor chuck, the profile can be continuously extruded from the extruder, and the floating platform is used for supporting the profile so as to prevent the profile from deforming, firstly, the tractor starts clamping the profile from one end of the floating platform, which is close to the profile, and then, the profile is continuously supported by a plurality of assemblies, and each time the plurality of assemblies are close to one assembly, the pressing device 11 on the tractor presses down the assembly, so that the lowering position of the conveying roller 1 is avoided, the tractor can smoothly pass through, and the conveying rollers 1 of other assemblies are kept still, so that the profile is continuously supported.
Preferably, as shown in fig. 2, the assembly further comprises two bearing seats 2, a rotating shaft 3 with two ends respectively installed on the two bearing seats 2, a supporting block 4 and a lever block 5 fixed on the rotating shaft 3; the lever block 5 comprises a resistance arm 501 and a power arm 502, the resistance arm 501 is connected with the power arm 502, the lever block 5 takes a fixed connection position with the rotating shaft 3 as a lever fulcrum, and the resistance arm 501 and the power arm 502 are connected together at the lever fulcrum.

Thus, according to the lever principle, the whole lever block 5 can rotate around the rotating shaft 3 by applying force to the resistance arm 501 or the power arm 502. The conveying roller 1 is provided with a central shaft 6, and the tail end of the resistance arm 501 and the supporting block 4 respectively support the two ends of the central shaft 6 in a common rotation mode, namely the central shaft 6 can rotate relative to the resistance arm 501 and the supporting block 4; the conveying roller 1 is parallel to the rotating shaft 3, and the resistance arm 501 and the supporting block 4 support the conveying roller 1 and can rotate by taking the axis of the rotating shaft 3 as the shaft; the resistance arm 501 of the lever block 5 is provided with a pressing part 10, the pressing part 10 is arranged between the tail end of the resistance arm 501 and the rotating shaft 3, the pressing part 10 is pressed down, the rotating shaft 3 is pressed to rotate in the bearing seat 2 in the positive direction, and the resistance arm 501 can be driven to rotate downwards, so that the position of the conveying roller 1 is driven to descend, and the effect of avoiding can be achieved when the movable processing device moves close to the conveying roller; the end, far away from the connection part of the resistance arm 501, of the power arm 502 of the lever block 5 is connected with the automatic resetting mechanism.
