[0032] Embodiment 2:

[0033] See also Figure 1-10 As shown, on the basis of embodiment 1, the present invention provides a technical solution: a stopper 11 is movably installed on one side surface of the spindle 8, an outer end movable cover 12 is movably installed on one side surface of the outer tube 1, an inner end cover 13 is detachably installed on the top of one side of the outer tube 1, a second connecting spring 14 is movably connected to one side surface of the spindle 8, a buckle sliding limit groove 15 is provided on one side surface of the inner end cover 13, a locking groove 121 is provided on the top surface of one side of the outer end movable cover 12, a locking hook 123 is fixedly connected to the side surface of the outer end movable cover 12 close to the locking groove 121, a locking ring 122 is movably connected to the top of one side of the spindle 8, the connection relationship between the locking ring 122 and the locking hook 123 is a movable snap connection, the connection relationship between the locking groove 121 and the locking ring 122 is a movable snap connection, the inner end cover 13 includes a top sealing cover 131, a connecting column 132 is fixedly connected to the top of one side of the top sealing cover 131, and a connecting buckle claw 133 is fixedly connected to the top of one side of the connecting column 132.

[0037] 1. When locked, the outer end cover is fixed, extending outward, and the built-in compression spring is in a stressed state, which can provide compression force for the assembly of the curtain and the side panel;

[0038] Second, when unlocked, the mandrel is in a free state and can be retracted in the inner tube, and the outer end cover is also retracted. This structure solves the technical barrier of being unable to be stored due to excessive compression force generated by long-distance compression, and realizes a linkage mechanism with compression force during loading and free retraction during storage;

[0039] By setting the sliding adjustment position of the outer end movable cover 12 on the outer tube 1, the length of the device can be directly adjusted, and the two ends of the long-distance telescopic curtain can be retracted. This product structure will realize the ultra-long telescopic storage function, which is very effective in solving the problem that the curtain cannot be stored. This structure can achieve a telescopic extension of more than 200 mm and achieve segmented compression force (there is compression force when loading, and there is no compression force when storing after unlocking), avoiding the possibility that the product cannot be realized due to the very large compression force generated by long-distance compression;

[0040] By setting the spindle 8 to rotate and adjust the position of the vertical stop block 9 and the vertical stop block 10, the vertical stop block 9 and the vertical stop block 10 are used to realize the locking and unlocking states of the device. When there is no need to adjust the position of the outer end movable cover 12, the entire device can be fixed, and the locking ring 122 is hooked to the locking hook 123 to further increase the locking stability. By setting the first connecting spring 6 and the second connecting spring 14, the effect of damaging the internal components during sliding can be avoided, which has a certain buffering effect and increases the service life of the device.
