Thus, the outer wall of the winding shaft 13 can be used for winding the safety rope 14, so that the structural utilization rate of the winding shaft 13 can be improved, and the structural compactness of the winding device 1 can be improved.

The fastening portion 131 of the spool 13 may be a fastening hole, a fastening groove, or a protruding fastening platform, and one or more elastic hooks 121 on the rotating handle 12 may be correspondingly disposed. For example: the winding shaft 13 can be provided with a clamping hole, and the rotating handle 12 is correspondingly provided with an elastic clamping hook 121; alternatively, as shown in fig. 5, two elastic hooks 121 are arranged on the rotating handle 12, the two elastic hooks 121 are circumferentially distributed at the bottom end of the connecting part of the rotating handle 12, and each elastic hook 121 comprises: a resilient arm 1211 formed by extending a bottom edge of the connecting portion of the rotary handle 12 downward in the axial direction, and a hook 1212 formed by extending a bottom of the resilient arm 1211 outward in the radial direction; the inner wall of the winding shaft 13 opposite to the connection part of the rotary handle 12 extends toward the central axis to form a convex ring, the bottom surface of the convex ring forms an annular clamping platform (i.e. the clamping part 131 of the winding shaft 13), and the clamping hook 1212 of the elastic clamping hook 121 on the rotary handle 12 is clamped on the clamping platform.

Wherein, the plurality of elastic hooks 121 are arranged, so that the connection firmness between the winding shaft 13 and the rotating handle 12 can be improved; the elastic arm is formed by extending the bottom of the connecting part of the rotating handle 12, so that the strength and rigidity of the elastic hook 121 can be improved; in addition, the strength and rigidity of the spool 13 can be improved by providing a projecting ring on the inner wall of the spool 13 and forming a catching portion of the spool 13 from the bottom surface of the projecting ring.

Wherein, the distance between the thread blocking wheel 151 and the thread blocking cylinder 152 can be smaller than the diameter of the safety rope 14 to improve the thread blocking effect.

In addition, as shown in fig. 8, one end of the winding shaft 13 near the rotating handle 12 (i.e., the top end of the winding shaft 13) may be extended outward in the radial direction to form the wire blocking wheel 151, so as to further improve the wire blocking effect.

In order to facilitate the wire outlet, a wire outlet hole (referred to as a second wire outlet hole 153) may be formed in the sidewall of the wire blocking cylinder 152, and the free end of the safety rope 14 may extend out of the housing 11 through the second wire outlet hole 153 and the first wire outlet hole 1113 in sequence.
