[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the fabric compresses the tensioning segment, the fabric drives the first articulated arm and the second articulated arm to be hinged to each other. The upward movement of the piston mainly overcomes the weight of the weight, that is, when the fabric applies pressure to the tensioning segment, the interaction force between the fabric and the tensioning segment is mainly provided by the gravity of the weight.

When the piston moves downward, the piston injects the pressure oil in the fixed tube into the interior of the driving box through the second connecting hole, and injects it into the interior of the liquid storage box through the plug-in tube, thereby allowing the pressure oil to enter the interior of the bellows through the through groove and the first connecting hole, and drive the mounting block to move toward one end of the tensioning shaft. When the mounting block moves toward one end of the tensioning shaft, the mounting block cooperates with the movable rod, the movable block and the connecting block to drive the mounting ring to move toward one end of the tensioning shaft, thereby allowing the mounting ring to cooperate with the first articulated arm and the second articulated arm to drive the tensioning pipe segment to move away from the tensioning shaft position, thereby allowing the tensioning pipe segment to always fit the surface of the fabric, and the interaction force thereof remains unchanged when the fabric is pressed and moved away.

[0020] 3. At the same time, by setting the first articulated shaft and the first articulated seat, when the first articulated arm and the second articulated arm are hinged to each other, the relative movement of the tensioning shaft and the tensioning pipe segment can be stably supported, and by setting the third articulated arm to cooperate with the fourth articulated arm, the second articulated seat and the second articulated shaft, the first articulated arm and the second articulated arm can be assisted to work, thereby making the relative movement of the tensioning shaft and the tensioning pipe segment more stable.

[0045] Working principle: When in use, the invention winds the cloth between the winding roller 2 and the tensioning tube segment 4. The usage method in the figure is to place the cloth at the bottom of the tensioning tube segment 4, or the winding rollers 2 at both ends can be moved downward and the cloth can be placed on the top of the tensioning tube segment 4 for use. The usage method to be used is selected according to different usage scenarios. When in use, first hang the weight of the target weight on the hook 707 as needed. When the cloth puts pressure on the tensioning tube segment 4, the tensioning tube segment 4 will drive the first articulated arm 511 and the second articulated arm 512 to be hinged to each other, and the distance between the tensioning tube segment 4 and the tensioning shaft 3 will be reduced. At this time, the tensioning tube segment 4 drives the mounting ring 510 to move to the end away from the tensioning shaft 3 through the first articulated arm 511. Then, the mounting ring 510 injects the pressure oil in the bellows 507 into the liquid storage box 701 through the connecting block 509, the movable block 504, the movable rod 505, the mounting block 506, the bellows 507, the first connecting hole 515 and the through groove 702, and then the pressure oil in the liquid storage box 701 enters the interior of the fixed tube 704 through the plug-in tube 709 and the second connecting hole 708 and increases the height of the piston 705. Since the piston 705 is hung with a weight through the piston rod 706 and the hook 707, the upward movement of the piston 705 is mainly to overcome the weight of the weight. That is to say, when the cloth applies pressure to the tensioning segment 4, the interaction force between the cloth and the tensioning segment 4 is mainly provided by the gravity of the weight. Since gravity is not 706, and the piston 705 moves downward. When the piston 705 moves downward, the piston 705 injects the pressure oil in the fixed tube 704 into the driving box 703 through the second connecting hole 708, and injects it into the liquid storage box 701 through the plug-in tube 709, so that the pressure oil passes through the through groove 702. The first connecting hole 515 enters the interior of the bellows 507 and drives the mounting block 506 to move toward one end of the tensioning shaft 3. When the mounting block 506 moves toward one end of the tensioning shaft 3, the mounting block 506 cooperates with the movable rod 505, the movable block 504 and the connecting block 509 to drive the mounting ring 510 to move toward one end of the tensioning shaft 3, so that the mounting ring 510 cooperates with the first hinged arm 511 and the second hinged arm 512 to drive the tensioning pipe segment 4 to move away from the tensioning shaft 3, so that the tensioning pipe segment 4 is always in contact with the surface of the cloth, and the interaction force thereof remains unchanged when the cloth is pressed and moved away. By setting the first hinged shaft 513 and the first hinged seat 514, when the first hinged arm 511 and the second hinged arm 512 are hinged to each other,It can stably support the relative movement of the tensioning shaft 3 and the tensioning tube segment 4, and by setting the third hinge arm 601 to cooperate with the fourth hinge arm 602, the second hinge seat 603 and the second hinge shaft 604, it can assist the first hinge arm 511 and the second hinge arm 512 to work, thereby making the relative movement of the tensioning shaft 3 and the tensioning tube segment 4 more stable. By setting the connecting pipe 711, and the two ends of the connecting pipe 711 are respectively connected to the liquid storage box 701, under the principle of the communicating vessel principle that the liquid pressure is equal everywhere, the two ends of the tensioning tube segment 4 and the cloth are completely equal under the interaction, so that the tensioning tube segment 4 is always in a constant pressure state with the cloth.
