It should be noted that the second sheath 322 includes a hook-shaped limiting surface, one end of the power steel sheet 321 includes a hook-shaped power surface matching with the hook-shaped limiting surface to prevent the power steel sheet 321 from sliding out of the second sheath 322, the second sheath 322 further includes a straight limiting surface, and one end of the power steel sheet 321 further includes a straight power surface parallel to the straight limiting surface; the height of the hook-shaped power surface is less than that of the hook-shaped limiting surface; and the height of the straight power surface is smaller than that of the straight limiting surface, so that the second sheath 322 has a certain space, and an up-and-down telescopic space is conveniently provided for the power steel sheet 321 when being bent.

The first sheath 312 includes a first sheath face and a second sheath face that are parallel, the first sheath face having a height that is less than the height of the second sheath face; one end of the constraint block 311 comprises a first constraint surface and a second constraint surface which are parallel, the height of the first constraint surface is smaller than or equal to that of the first sheath surface, the height of the second constraint surface is larger than that of the first constraint surface and smaller than that of the second sheath surface, the first constraint surface is matched with the first sheath surface, and the second constraint surface is matched with the second sheath surface to limit the telescopic distance. The power part is located the top of restraint piece, and when the power part realized buckling, the better limit of the restraint piece of below was the degree of buckling of power part, and is more excellent, and restraint piece 311 of restraint piece is the metal material to increase intensity, the metal upper surface of restraint piece 311 places power steel piece 321 and crosses the bend.

The connecting and restraining member and the power member in this embodiment may be formed by stamping, cutting, or the like.

Preferably, wearable equipment in this embodiment includes smart watch, intelligent bracelet etc. and it has flexible screen module wherein smart watch and intelligent bracelet, can carry out deformation in the scope of buckling that allows.
