Detailed description of the invention
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 8, button 4 is made up of jointly upper lower plate and separation cone and the clamping type structure coordinated with zipper strip 15, the train wheel bridge of button 4 offer corresponding respectively with left and right zipper strip 15 and run through left chute 12 and the right rail 9 of train wheel bridge, guide holder 6 is the reclinate Rectangular Plate Structure in rear and front end, and guide holder 6 is set in parallel in the top of left chute 12 and right rail 9 and is connected by the train wheel bridge of front and back elbow with button 4.Left driving head 5 and right driving head 10 are eccentric wheel type structure, left driving head 5 and right driving head 10 all offer stopper slot 13, driving shaft 3 is horizontally installed between the train wheel bridge of guide holder 6 and button 4, driving shaft 3 is provided with left and right alignment pin 14, the left axle journal of driving shaft 3 is connected with left driving head 5 axle be positioned on the left of guide holder 6, the right axle journal of driving shaft 3 is connected with right driving head 10 axle be positioned on the right side of guide holder 6, stopper slot 13 on left driving head 5 and right driving head 10 coordinates with the left and right alignment pin 14 on driving shaft 3 respectively, torsionspring 11 is provided with between left driving head 5 and driving shaft 3, torsionspring 11 is provided with between right driving head 10 and driving shaft 3, left driving head 5 and right driving head 10 align with left chute 12 and right rail 9 respectively.Determine handle 1 and fixed handle 2 is semi-circular shape structure, the follower head of the lower end and guide holder 6 of determining handle 1 is connected by rotating shaft 7, the lower end of fixed handle 2 is connected with the left and right spindle nose key of driving shaft 3, determine the upper end of handle 1 and the upper end chain connection of fixed handle 2, determine handle 1 and form cirque structure with fixed handle 2, determining to be provided with back-moving spring 8 between handle 1 and fixed handle 2.
In Fig. 1, Fig. 6, Fig. 7, Fig. 8, Fig. 9, in using, when zipper strip 15 is fixed, button 4 can be promoted move forward and backward along zipper strip 15 by determining handle 1.When zipper strip 15 is not fixed, by compression set handle 1 and fixed handle 2, fixed handle 2 can promote driving shaft 3 and move backward along guide holder 6, the eccentric end of left driving head 5 and right driving head 10 will overturn and enter in left chute 12 and right rail 9 respectively under the effect of torsionspring 11 simultaneously, when left driving head 5 or right driving head 10 engage with left zipper strip 15 or right zipper strip 15, left driving head 5 or right driving head 10 will be located by alignment pin 14 and stopper slot 13, continue to press compression set handle 1 and fixed handle 2, determine handle 1 and can promote button 4 and move forward along zipper strip 15.Unclamp when determining handle 1 and fixed handle 2, fixed handle 2 returns promoting driving shaft 3 under the effect of back-moving spring 8 along guide holder 6, due to the single effect of alignment pin 14 and stopper slot 13, therefore left driving head 5 and right driving head 10 can return along left chute 12 and right rail 9 respectively.When left driving head 5 and right driving head 10 get back to start position, left driving head 5 can be separated with zipper strip 15 with the eccentric end of right driving head 10.
