Specifically, during clip 224 is from reset condition trend interlocking pattern, cylinder 2241 promotes the water of pushing block 2241 Flat reach, pushing block 2242 promotes first rotating shaft 2247a and the movement of the forward direction of ambulatory splint 2243 simultaneously, and at this moment, due to even Strap is rotatably fixed in the lower end for being connected to the first connecting rod 2246a and second connecting rod 2246b of ambulatory splint 2243 2244 both sides, therefore ambulatory splint 2243 is simultaneously by the way that first connecting rod 2246a is using the second rotating shaft 2247b as turning point and passes through Second connecting rod 2246b is moved downwards using the 4th rotating shaft 2247d as turning point, at the same time, and first rotating shaft 2247a is from breach 2242c top is gradually moved to breach 2242c bottom, until upper grip 2245a is engaged fixed lower chuck Untill 2245b.That is, with being pushed away before pushing block 2242, ambulatory splint 2243 is forwardly and downwardly moved while continuous.

It will be apparent that passing through first connecting rod 2246a and second connecting rod 2246b common setting so that clip 224 can be with Double link synergy is carried out, the stability of the occlusion of clip 224 is improved.

Because when being engaged using plain connecting rod (such as second connecting rod 2246b), although ambulatory splint 2243 can be with Bite down on, but because the tie point of second connecting rod 2246b and ambulatory splint 2243 is two points, do not constitute the knot in a face Structure, hence in so that the occlusion of ambulatory splint 2243 and unstable；And use the setting of double link, i.e. first connecting rod 2246a and the Two connecting rod 2246b, because the tie point of two connecting rods and ambulatory splint 2243 is four points, constitute a complete face knot Structure, hence in so that the more stable entirety of ambulatory splint 2243 is moved down and is engaged.

Further, because the first connecting rod 2246a being vertically arranged fits with the side interior wall of ambulatory splint 2243, vertically The second connecting rod 2246b of setting fits with the sidepiece outer wall of ambulatory splint 2243 so that first connecting rod 2246a and second connecting rod The tie point of 2246b and ambulatory splint 2243 is formed at the isosceles trapezoid in same level, and it will be apparent that in mechanics In angle, the stability of isosceles trapezoid framework is higher than the framework of parallelogram.Therefore it is such to set so that ambulatory splint 2243 during being engaged, more stable.

In addition, first connecting rod 2246a top two sides respectively with lug boss 2242b and the sidepiece of ambulatory splint 2243 2243b inwalls are fitted, the setting that second connecting rod 2246b fits with the sidepiece outer wall of ambulatory splint 2243 so that when pushing block 2242 When driving ambulatory splint 2243, it is to avoid first connecting rod 2246a is offset in the hollow-out parts 2243c of ambulatory splint 2243, from And the phenomenon for driving ambulatory splint 2243 to offset, so as to improve ambulatory splint 2243 and the anterior essence being engaged of strap 2244 Accuracy and stability；

Because the clip of stable occlusion, the interlaced occlusion of sawtooth on the folder face of upper lower chuck (2245a, 2245b), one Denier ambulatory splint 2243 is offset, it is likely that the upper grip 2245a's for causing to be arranged on ambulatory splint body 2243a bottoms Sawtooth and lower chuck 2245b sawtooth occur between the phenomenon to top, i.e., the sawtooth of upper lower chuck without progress patho-occlusion, and So that the occlusion of upper lower chuck is unstable, therefore first connecting rod 2246a top two sides are pressed from both sides with lug boss 2242b and activity respectively The sidepiece 2243b laminatings of plate 2243, the setting that second connecting rod 2246b fits with the sidepiece outer wall of ambulatory splint 2243, it is to avoid Above-mentioned phenomenon.Certainly it should be noted that the uniform geometrical clamp of first connecting rod 2246a and second connecting rod 2246b lower side Plate 2244 is fitted.
