As shown in fig. 1 to 7, a reel 10 is provided according to an embodiment of a first aspect of the present application. The reel 10 includes a first shaft body 110, a second shaft body 120, a driving assembly 130, a first hinge 140, a second hinge 150, a third hinge 160, and a third shaft body 170.
As shown in fig. 1 to 3, specifically, the second shaft body 120 is axially spaced from the first shaft body 110. The driving assembly 130 is connected to the second shaft 120, and the driving assembly 130 is used for driving the second shaft 120 to move to approach or move away from the first shaft 110. One end of the first hinge 140 is hinged to the first shaft body 110. One end of the second hinge 150 is hinged to the second shaft body 120, and the other end of the second hinge 150 is hinged to the first hinge 140. One end of the third hinge 160 is hinged to the other end of the first hinge 140. The third shaft body 170 is disposed along the axial direction of the first shaft body 110, and is located at one side of the circumferential direction of the first shaft body 110 and the second shaft body 120. The third shaft body 170 is connected to the other end of the third hinge 160. The driving assembly 130 drives the second shaft 120 to approach the first shaft 110, and pushes the first hinge 140 and the second hinge 150 to rotate, so that the first hinge 140 drives the third hinge 160, and the third hinge 160 pushes the third shaft 170 to move away from the first shaft 110 in the radial direction, thereby increasing the radial dimension of the reel 10. When the driving assembly 130 drives the second shaft 120 to move away from the first shaft 110, the second shaft 120 pulls the first hinge 140 and the second hinge 150 to rotate, and at the same time, the first hinge 140 drives the third hinge 160, and the third hinge 160 pulls the third shaft 170 to be close to the first shaft 110 in the radial direction.

By adjusting the third shaft 170 to be radially far from or close to the first shaft 110, the crease generated by the flexible screen 210 on the reel 10 can be reduced. Meanwhile, by adjusting the third shaft 170 to be radially far away from or close to the first shaft 110, the retraction speed of the flexible screen 210 can be adjusted, so that the purpose of rapidly unfolding or folding the mobile phone with the flexible screen 210 is achieved. In addition, the third shaft 170 is radially far away from or close to the first shaft 110, so that the tightness of the flexible screen 210 can be adjusted.
