The specific embodiment
Referring to Fig. 1 to Figure 11, present embodiment comprises that a jump ring leads to heart screw 1, a support bar 2, a torsion spring 3, a portable plate 4, two stators 5, a deduction sheet 6, a gear shift sheet 7 and a jump ring 8, the logical heart screw 1 of jump ring is provided with the mesopore 102 of the external screw thread 101 and the logical heart, mesopore 102 is hexagon at the top, at middle part and bottom is circular, mesopore 102 matches with the external diameter of support bar 2 at the internal diameter at middle part, gapped therebetween, the logical heart screw 1 of jump ring also is provided with the groove 103 that communicates with mesopore 102 above its external screw thread 101, insert in the mesopore 102 of the logical heart screw 1 of jump ring the lower end of support bar 2, jump ring 8 is stuck in the groove 103 of the logical heart screw 1 of jump ring and with the position, hole 201 of support bar 2 and cooperates, support bar 2 is automatically locked, support bar 2 also can arbitrarily be extracted simultaneously, the other end of support bar 2 is fixedlyed connected with two stators 5, torsion spring 3, deduction sheet 6, gear shift sheet 7 and portable plate 4 are installed between two stators 5, fixedly connected by pin with deduction sheet 6 and be installed on two stators 5 in the bottom of portable plate 4, portable plate 4, but deduction sheet 6 and pin unitary rotation, outer rim at deduction sheet 6 is provided with tooth 601, gear shift sheet 7 usefulness pins are installed on two stators 5 and can rotate around pin, gear shift sheet 7 is provided with the endoporus of band tooth 701, its profile of tooth is corresponding with the profile of tooth of deduction sheet 6, deduction sheet 6 is arranged in the endoporus of gear shift sheet 7, and the two ends of torsion spring 3 are separately fixed on stator 5 and the gear shift sheet 7.
Said fixing sheet 5, torsion spring 3, deduction sheet 6, gear shift sheet 7 and portable plate 4 belong to the backrest angle governor motion.The utility model can also adopt other similar means.
Referring to Fig. 9 figure to Figure 11, the mesopore 102 of the logical heart screw 1 of jump ring is a hexagon at the top, is convenient to cooperate with instrument carry out the logical heart screw of installation or removal jump ring.
Referring to Figure 12 to Figure 14, the principle of present embodiment is as described below:
When portable plate 4 by initial position shown in Figure 12 during to position shown in Figure 14 motion, it is moving that portable plate 4 promotes deduction sheet fortune 6, gear shift sheet 7 is under the effect of torsion spring 3, can make portable plate 4 make one-stage movement, the tooth of diverse location is meshed with tooth on the gear shift sheet 7 successively on the deduction sheet 6 in this process, promptly formed different gears in each position, between each gear deduction sheet 6 and gear shift sheet 7, played the non-return effect, as shown in figure 13 by the engagement of tooth.The quantity of gear is provided with as required, is determined jointly by the number of teeth of deduction sheet 6 with gear shift sheet 7.
When portable plate 4 moves to position shown in Figure 14, portable plate 4 reaches maximum open configuration, deduction sheet 6 breaks away from mutually with the tooth of gear shift sheet 7, be neutral position this moment, deduction sheet 6 jack-up gear shift sheets 7, portable plate 4 from then on position to initial position is in free state, and portable plate 4 can come back to initial position.
