In one embodiment of the invention, draw the rotating part 14 of board to be disposed proximate to circular arc, connect the downside that through hole 16 is arranged on the center of circle of rotating part 14, so when board is drawn in pull-up, shell fragment 4 is applied bigger pressure by rotation section branch, makes the further flexural deformation of shell fragment, with pressing spring at present.
As shown in figs. 10-11, when drawing board 1 to keep flat, the rotating part 14 drawing board is against on shell fragment 4, connecting axle 3 will draw board 1 to be fixed on pull head base 2, shell fragment 4 is in the state being slightly curved, and spring 5 is in oppressed state, and elongated insertion part 11 stretches in locking through hole 21a simultaneously, it is against on zipper sprocket, stops the slip of pull head；Along with drawing board 1 to be pulled up, rotating part 14 presses shell fragment 4 gradually downward, and shell fragment degree of crook increases, further lower pressing spring 5, and elongated insertion part also leaves slide fastener coupling element gradually, and pull head can slide；When drawing board 1 to be pulled up to the limit, stopping part 15 can contact with the back concave surface 21c of semicircular concave, makes to draw board to further pull up, and elongated insertion part 11 deviates to lock through hole 21a.
As shown in figure 12, in one embodiment of the invention, draw the stopping part 15 of board to be provided with prominent angle, when rotation draws board to be against on semicircular concave to prominent angle, draw board to rotate further.
When unclamp draw board time, due to the force action of spring and shell fragment, shell fragment reduces bending, drives and draws board to rotate, pull-up return to flat condition, and elongated insertion part snaps in locking through hole simultaneously, is against on slide fastener coupling element, stops pull head slip.
Drawing board keeping flat, when pull-up and complete pull-up, shell fragment is in differently curved state, draws board rotating part to contact with shell fragment all the time, and shell fragment is pressuring spring all the time, cannot continue pull-up with the back concave surface 21c of semicircular concave when stopping part 15 contacts.
Shell fragment is arranged in arc concave surface 24, by breach 41 is stuck in fixed position on boss 22, it is prevented that come off.When breach 41 damages, shell fragment position offsets, and front vertical 24b and rear vertical 24c can stop shell fragment landing, departs from arc concave surface 24.
As shown in figure 13, in one embodiment of the invention, connect axle 3 and be provided with the cylinder of fixing end 33 for top, bottom is for being set to hollow tubular, after installation, bottom is carried out punching press, hollow pipe can form ledge arrangement by turned-out volume, and lug external diameter is more than described connection through-hole diameter, it is prevented that connects axle and comes off.
As shown in figure 14, in one embodiment of the invention, connect axle 3 and be set to cylinder, one end is provided with the fixing end 32 of gear-like, the tip diameter of gear is more than the diameter of the first through hole and the second through hole, during installation, connection axle 3 is stretched into the first through hole 23a of upper panel, second through hole 23b and draw the connection shaft through-hole 16 of board 1, then fixing end 32 is applied external force, the shape of fixing end 32 is destroyed, snap in the first through hole 23a or the second through hole 23b of upper panel by force, connect axle 3 at the first through hole 23a and the second through hole 23b place all without exposing, all snap in through hole.
As shown in figure 15, upper panel side is additionally provided with the ring-shaped platform 29 prominent to the second through hole side around the first through hole 23a place, when board is drawn in installation, board 1 is drawn to be against on ring-shaped platform 29, reduce and draw the side of board and the contact area of upper panel side, only contact at ring-shaped platform place, it is ensured that draw the board 1 can flexible rotating.
Locking through hole 21a is arranged on the axis of described upper panel, equal with the distance of the first through hole 23a and the second through hole 23b, elongated insertion part 11 snaps in locking through hole 21a, just stretches into slide fastener coupling element occlusion place, elongated insertion part 11 is avoided to be stuck in zipper cloth belt place, it is ensured that locking effect.
Convex front surface 24e is provided with the block 24g exceeding convex front surface in the position relative with boss 22, reduces the side of shell fragment and the contact area of upper panel side, makes the shell fragment 4 can flexural deformation flexibly and reinstatement.
When board 1 is drawn in pull-up, along with the pull-up drawing board, rotating part 14 pressure shell fragment 4 down gradually, increases shell fragment 4 crooked radian, unclamps when drawing board 1, effect due to shell fragment 4, drawing board 1 meeting automatic rebounding, reply the position kept flat, elongated insertion part 11 stretches into locking through hole 21a simultaneously,, unexpected slip will not be there is in pull head locking position.
The announcement of book and instruction according to the above description, above-mentioned embodiment can also be modified and revise by those skilled in the art in the invention.Therefore, the invention is not limited in detailed description of the invention disclosed and described above, some modifications and changes of invention be should also be as falling in the scope of the claims of the present invention.Although additionally, employ some specific terms in this specification, but these terms are intended merely to convenient explanation, and the present invention does not constitute any restriction.
