[0012] Beneficial effects:

[0013] 1. In the application, through the setting of two fixed plates, two movable plates and two groups of connecting springs, the installation and removal of the flexible protective cloth can be conveniently and quickly realized by the limiting between the movable plate and the fixed plate and the elastic force of the connecting spring. Compared with the existing screw or welding fixing mode, the flexible protective cloth will not be damaged, so that the flexible protective cloth can be reused, and at the same time, it can ensure that the flexible protective cloth will not appear folding phenomenon, improve the aesthetic effect, in addition, the elastic force of the connecting spring can also be used to effectively buffer the falling debris, prolong the service life of the flexible protective cloth and avoid the safety risk caused by the secondary falling of the debris, improve the protection effect of the steel shed, and when the debris falls on the flexible protective cloth, the kinetic energy of the debris will cause the flexible protective cloth to be indented, so as to drive the connecting springs on both sides to stretch, in this process, through the elasticity of the flexible protective cloth itself and the buffering of the two groups of connecting springs, the kinetic energy of the falling debris can be offset, and the sliding connection of the adjusting assembly and the fixed plate through the movable plate can meet the installation of flexible protective cloth of different thickness.

[0014] 2. In the application, through the setting of two groups of compression springs and two pressing plates, on the one hand, the elastic force of the compression spring can improve the fixing effect of the flexible protective cloth, and further improve the wind resistance of the flexible protective cloth, on the other hand, the flexible protective cloth can also be flattened, further preventing the flexible protective cloth from folding; through the setting of the first roller shaft, the frictional resistance of the flexible protective cloth during movement can be reduced, the installation and removal efficiency can be improved, and the damage of the flexible protective cloth due to friction can be prevented; combined with the setting that the two first roller shafts are respectively installed on the side of the two fixed plates away from each other, it can be ensured that the flexible protective cloth will not contact the side surface of the fixed plate at the corner, further reducing the frictional resistance of the flexible protective cloth during movement.

[0015] 3. In the application, through the sliding connection of the bracket and the side surface of the support frame, the shielding area of the flexible protective cloth to the side surface of the support frame can be conveniently adjusted to meet different use requirements, and combined with the setting of the bolt locking, the initial elastic force of the connecting spring can be adjusted, so that the installation and removal efficiency can be improved while ensuring the structure is firm.

[0016] 4、In the present application, through the setting of the winding assembly, the winding and release of the flexible protective cloth can be realized, the fixed effect of the flexible protective cloth is ensured, the phenomenon of damage to the flexible protective cloth due to pulling is avoided, and the protective effect is reduced or even lost when the support slides upward and the flexible protective cloth at the top is loose and falls. At this time, the excess flexible protective cloth is wound by the winding assembly, so that the flexible protective cloth at the top always has a certain tension. When the support slides downward, the elasticity of the flexible protective cloth is damaged due to the limited length of the flexible protective cloth, and the flexible protective cloth is torn in severe cases. At this time, the flexible protective cloth is released by the winding assembly to compensate for the length of movement. In combination with the settings of the at least two second roller shafts, the mounting frame fixing rod and the movable rod, the length change of the flexible protective cloth during the movement of the support can be compensated by the movement of the movable rod, so that the flexible protective cloth at the top is always in the best state. Through the setting of the reset spring, automatic compensation can be realized, that is, when the support slides upward, the second roller shaft will move away from the side of the support frame under the driving of the movable rod, and when the support slides downward, the second roller shaft will move close to the side of the support frame under the driving of the movable rod. In combination with the setting that when the support is located at the bottom end of the side of the support frame, the reset spring is in a compressed state and has the maximum elastic force, the position of the support sliding downward can be limited.

[0017] 5、In the present application, through the settings of the two mounting holes, the two slide columns, the two pin shafts and the plurality of through holes, the height of the clamping space between the movable plate and the fixed plate can be adjusted by the cooperation of the through holes of the pin shafts, so as to meet the installation of flexible protective cloths of different thicknesses.
