The rotating shaft mounting base 13 has a rotating shaft mounting hole, the extension direction of which is parallel to the extension direction of the slide rail 2a. The unwinding control mechanism includes a magnetic resistance device 4 and a hand-operated expansion shaft 5. The magnetic resistance device 4 is fixedly installed on one side of the rotating shaft mounting base 13, and the resistance device shaft 4a of the magnetic resistance device 4 is rotatably mounted on the rotating shaft mounting base 13. A controller 6 electrically connected to the magnetic resistance device 4 is also provided on the mounting frame 1. The controller 6 and the module bracket 3 are mounted on the same longitudinal beam of the mounting frame 1 for easy operation and arrangement.

[0029] The hand expansion shaft 5 is located on the other side of the rotating shaft mounting seat 13, and the extension direction of the hand expansion shaft 5 is parallel to the extension direction of the sliding rail 2a. The rotating shaft 5a of the hand expansion shaft 5 is coaxially connected with the resistance shaft 4a of the magnetic resistance device 4 and rotates synchronously. The damping size of the magnetic resistance device 4 can be adjusted by the controller 6, so as to control the damping size when the hand expansion shaft 5 rotates, and adjust the tension of the release cloth roll B mounted on the hand expansion shaft 5 during unwinding. The hand expansion shaft 5 comprises a rotating shaft 5a, an expansion assembly, an elastic sleeve 5b and a plurality of strip tiles 5c which are coaxially arranged in the radial direction from inside to outside in sequence. Both ends of the rotating shaft 5a are threaded segments 5a1 with external threads, and the thread directions of the two threaded segments 5a1 are opposite. The end of the rotating shaft 5a close to the rotating shaft mounting seat 13 is reduced in diameter to form a connecting segment 5a2 with the resistance shaft 4a. One end of the connecting segment 5a2 is connected with the threaded segment 5a1, and the other end has external threads and is screwed with the resistance shaft 4a. The rotating shaft 5a is integrally formed, and has high overall structural strength.

When the two adjusting nuts 5d are moved away from each other, each expansion strip 5e slides inward along the radial direction under the elastic force of the elastic sleeve 5b, thereby driving each strip-shaped tile 5c to move inward along the radial direction, and the hand expansion shaft 5 is tightened. The variable diameter function of the hand expansion shaft 5 makes the installation of the release cloth roll more convenient, and can effectively prevent the release cloth roll from deviating during unwinding.
