Elongated insertion part 11 snaps in locking through hole 21a, is against at zipper sprocket, and locking zipper prevents pull head from sliding.
In one embodiment of the invention, draw the rotating part 14 of board to be disposed proximate to circular arc, connect through hole 16 and be arranged on
The downside in the center of circle of rotating part 14, so when board is drawn in pull-up, rotation section branch applies bigger pressure to shell fragment 4, makes
The further flexural deformation of shell fragment.
In one embodiment of the invention, the stopping part 15 of board is drawn to be provided with prominent angle, when rotation draws board to support to prominent angle
Time on semicircular concave,
As shown in figs. 10-11, when drawing board 1 to keep flat, drawing the rotating part 14 of board to be against on shell fragment 4, connecting shaft 3 will be drawn
Board 1 is fixed on pull head base 2, and shell fragment 4 is in the state being slightly curved, and elongated insertion part 11 stretches into locking through hole 21a simultaneously
In, 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 gradually downward
4, shell fragment degree of crook increases, and elongated insertion part the most gradually leaves slide fastener coupling element, and pull head can slide；It is pulled up to pole when drawing board 1
In limited time, stopping part 15 can contact with back concave surface 21c of semicircular concave, makes to draw board to further pull up, and locks
11 abjection locking through hole 21a.
Drawing board keeping flat, when pull-up and complete pull-up, shell fragment is in differently curved state, draw board rotating part all the time with shell fragment
Contact, cannot continue pull-up with back concave surface 21c of semicircular concave when stopping part 15 contacts.Unclamping when drawing board, shell fragment 4 inclines
To in reinstatement, reduce flexibility, pressure can be applied to drawing board 1, make to draw board 1 to reply the position kept flat.
Shell fragment is arranged in arc concave surface 24, by breach 41 is stuck in fixed position on boss 22, prevents from coming off.
When breach 41 damages, and shell fragment position offsets, front vertical plane 24b and rear vertical plane 24c can stop shell fragment landing, departs from
Arc concave surface 24.
As shown in figure 14, in one embodiment of the invention, connecting shaft 3 is provided with the cylinder of fixing end 33 for top,
Bottom, for being set to hollow tubular, carries out punching press to bottom after installation, and hollow pipe can form ledge arrangement by turned-out volume, convex
Ear external diameter is more than described connection through-hole diameter, prevents connecting shaft from coming off.
As shown in figure 15, in one embodiment of the invention, connecting shaft 3 is set to cylinder, and one end is provided with gear-like
Fixing end 32, the tip diameter of gear is more than the first through hole and the diameter of the second through hole, during installation, connecting shaft 3 is stretched into
First through hole 23a of upper panel, the second through hole 23b and draw the connecting shaft through hole 16 of board 1, then apply fixing end 32
External force, the shape of fixing end 32 is destroyed, and snaps in the first through hole 23a or the second through hole 23b of upper panel by force, connects
Axle 3 all without exposing, all snaps in through hole at the first through hole 23a and the second through hole 23b.
As shown in figure 16, upper panel side is additionally provided with the ring-shaped platform prominent to the second through hole side at the first through hole 23a
29, when board is drawn in installation, draw board 1 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, it is ensured that draw the board 1 can be with flexible rotating.
Locking through hole 21a is arranged on the axis of described upper panel, with the first through hole 23a and the distance of the second through hole 23b
Equal, elongated insertion part 11 snaps in locking through hole 21a, just stretches at slide fastener coupling element occlusion, it is to avoid elongated insertion part 11 is stuck in zipper cloth
At band, 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 with upper
The contact area of fin side, makes the shell fragment 4 can flexural deformation flexibly and reinstatement.
When board 1 is drawn in pull-up, along with drawing the pull-up of board, rotating part 14 presses down shell fragment 4, increases shell fragment 4 crooked radian,
Unclamp when drawing board 1, due to the effect of shell fragment 4, draw board 1 can automatic rebounding, reply the position kept flat, elongated insertion part 11 simultaneously
Stretching into locking through hole 21a, pull head position locks, unexpected slip will not occur.
The announcement of book and teaching according to the above description, above-mentioned embodiment can also be entered by those skilled in the art in the invention
Row change and amendment.Therefore, the invention is not limited in detailed description of the invention disclosed and described above, to some invented
Modifications and changes should also be as falling in the scope of the claims of the present invention.Although additionally, this specification employing one
