By accompanying drawing as can be known, the utility model has the overcoat (5) of band slit (15) and end slot (14) (referring to figure 3), its design feature is, it also has central shaft shown in Figure 2 (4), and this central shaft is set with on (4) Movable hollow rotating shaft (3), namely hollow rotating shaft (3) can be upper around the axis flexible rotating at central shaft (4), Hollow rotating shaft (3) places cylinder (1), the circumferential weld between hollow rotating shaft (3) and cylinder (1) inwall In torsion spring (being torque spring) (2) is housed, the two ends of this torsion spring (2) respectively with corresponding locking plug ( 6) be fixedly connected with (referring to Fig. 1), one of them locking plug (6) is fixedly connected on one of cylinder (1) End and another locking plug (6) with place cylinder (1) other end and cylinder (1) can be relatively its around axis The location gear ring (7) that rotates is fixedly connected with, and described cylinder (1) places overcoat (5) and makes the location gear ring (7) positioning tooth on is connected in the end slot (14) of overcoat (5), is wound on rectangular on the cylinder (1) One end of shape drawing (8) is fixedly connected on the upper and other end of this cylinder (1) by the slit (15) of overcoat (5) In stretch out and at this end bending dop (9) be housed, the opening end of overcoat (5) be equipped with end-sealing cap (13) ( Referring to Fig. 4), an end of central shaft (4) places the axle sleeve of overcoat (5) bottom and the other end places end socket In the cap (13) and which is provided with locating ring (11), in this locating ring (11) and end-sealing cap (13) between the top Holddown spring (12) is housed.

Syndeton between described locking plug (6) and the torsion spring (2) can be to establish at plug (6) Put the external screw thread corresponding to the circle distance of torsion spring (2), make the two screw connection with thread connecting mode, also available its Its prior art method is fixedly connected with, and each locks plug (6) and corresponding cylinder (1) one end or location gear ring (7) be fixedly connected with, can be the syndeton of employing voussoir and wedge groove shown in Figure 1, also available gluing Gum deposit is the two fixed bonding, or with the alternate manner of prior art the two is fixedly connected with. Described strip drawing The making material can be other class of various paper materials, plastics, cloth (silk fabric) material, nonwoven or prior art Like material, it on contained pattern or literal or the combination of the two can arrange according to actual needs, such as souvenir picture, electricity Words number etc. Pattern can be documented in the one or both sides of drawing.

Design principle of the present utility model and using method are, because the two ends of torsion spring (2) are stifled by two lockings Head (6) is an end and the connection of being connected through positioning tooth figure (7) of same cylinder (1) respectively) overcoat (5) one ends Be fixedly connected with, when pulling out the drawing (8) that is wound on the cylinder (1) through dop (9), because cylinder (1) rotation (rotating around central shaft (4)) is taken up torsion spring (2), and the drawing of pulling out (8) supplies The people watches; When unclamping dop (9), drawing (8) can bounce back under torsion spring (2) reseting elasticity effect On the cylinder (1), because hollow rotating shaft (3) can be at the upper flexible rotating of central shaft (4), so make drawing (8) Pull out and bounce back lighter, reliable.
