In order to make explanation more clear, the following stated front, rear, left and right all are as standard, with position opposite shown in the reality in the part rearview with Fig. 1.
See also Fig. 1, shown in Figure 2; Stiching instrument of the present invention comprises jaw 1, nail bin groupware 2, propulsive mechanism 3, firing lock 4, SR, fore-stock plate 5 and after-poppet plate 6; Wherein, Propulsive mechanism 3 comprises forward and backward assembly clamping plate 31,32, and closed locking plate 7 is installed between front assembly clamping plate 31 and the fore-stock plate 5, and percussion locking plate 8 is installed between back assembly clamping plate 32 and the after-poppet plate 6.
Specifically, please cooperate and consult shown in Figure 3ly, be provided with cylindrical protrusion 71 at the leading flank of closed locking plate 7, be provided with spring fixed hole 72 in the lower left of cylindrical protrusion 71, the upper left side of cylindrical protrusion 71 is provided with outstanding forward spacing preiection 73.Please cooperate and consult shown in Figure 4ly,, be provided with lock projection 74 at left upper end at the trailing flank of closed locking plate 7.
Please cooperate and consult shown in Figure 5ly, the cylindrical protrusion 71 of closed locking plate 7 is passed the circular hole of fore-stock plate 5, makes closed locking plate 7 can cylindric 71 rotate around fore-stock plate 5 for axle.Be fixed with spring 51 between spring fixed hole 72 and the fore-stock plate 5,, resist turning clockwise of closed locking plate 7 to the right so that tensile elastic force to be provided.Spacing preiection 73 extends to the top of fore-stock plate 5, to limit the scope that is rotated counterclockwise of closed locking plate 7.
Please cooperate and consult shown in Figure 6ly, the lock projection 74 of closed locking plate 7 is stuck in front assembly clamping plate 31 right parts (shown in Fig. 6 for left part) top, and front assembly clamping plate 31 are locating to be provided with closed locked groove 311 near its right-hand member (being left end shown in Fig. 6).
Please cooperate and consult Fig. 7, shown in Figure 8, the trailing flank of percussion locking plate 8 is provided with cylindrical protrusion 81, below the leading flank of pulling the trigger locking plate 8, cylindrical protrusion 81, is provided with arc fin 82, is provided with the protruding draw-in groove 83 of trigger in the lower left corner of arc fin 82.In addition, also be provided with spring fixed hole 84, also be provided with position limiting structure on the upper left side of cylindrical protrusion 81 in the lower left of cylindrical protrusion 81.Preferable, percussion locking plate 8 the protruding draw-in groove 83 of trigger forms by β shape convex surface as shown in the figure, position limiting structure comprises the zigzag convex surface 85 that is arranged on percussion locking plate 8 leading flanks, and is arranged on the spacing preiection 86 of pulling the trigger locking plate 8 trailing flanks.
Please cooperate consult shown in Figure 9; Firing lock 4 of the present invention mainly comprises trigger 41; Trigger 41 is rotatably connected through turning cylinder 42 and forward and backward supporting plate 5,6; And being provided with protrudingly 43 at the upper right side of trigger 41, the arc fin 82 of percussion locking plate 8 promptly is that protruding 43 movement locus right side is provided with when trigger 41 rotates.Preferable, the left upper end of trigger 41 is fixed with plectrum 44 through two screws, and promotes the forward and backward assembly clamping plate 31,32 of propulsive mechanism 3 through this plectrum 44.
Please cooperate and consult Figure 10, shown in Figure 11, the cylindrical protrusion 81 of percussion locking plate 8 is passed the circular hole of after-poppet plate 6, makes that percussion locking plate 8 can cylindrical protrusion 81 be that axle rotates around after-poppet plate 6.Be fixed with spring 61 between spring fixed hole 84 and the after-poppet plate 6, so that (shown in Figure 11 for left) to be provided to the right tensile elastic force, impel percussion locking plate 8 counterclockwise (shown in Figure 11 for clockwise) rotate.
Please cooperate and consult Fig. 6, Figure 10, shown in Figure 12, before percussion: the lock projection 74 of closed locking plate 7 is supported in the right part of front assembly clamping plate 31 (shown in Figure 6 is left part) upper edge; Convex surface 85 lower edges of percussion locking plate 8 are supported in the right-hand member upper edge of back assembly clamping plate 32, though the tension of spring 62 is arranged, closed locking plate 8 can not rotate.
In the percussion process; Hold trigger action 41; Plectrum 44 promotes propulsive mechanisms 3 to left movement: front assembly clamping plate 31 with respect to closed locking plate 7 left (shown in Fig. 6 for to the right) advance, lock projection 74 is slided in the upper edge of front assembly clamping plate 31, when the right-hand member that slides to front assembly clamping plate 31 (being left end shown in Fig. 6); Under the tension of spring 51; Closed locking plate 7 counterclockwise (being clockwise shown in Fig. 6) rotates, and lock projection 74 snaps in the closed locked groove 311 of front assembly clamping plate 31, thereby realizes closed and locked; Back assembly clamping plate 32 break away from convex surface 85 gradually, but the convexity 43 of trigger 41 props up the arc fin 82 of closed locking plate 8 always in motor process, and closed locking plate 8 still can not rotate.
Percussion finishes the back: unclamp trigger 41, because the locking effect of closed locking plate 7, does not return with trigger 41 propulsive mechanism 3 position that keeps moving to left; Protruding 43 of trigger breaks away from arc fins 82 with trigger 41; Closed locking plate 8 rotates counterclockwise under the tension of spring 62 and is state shown in Figure 12, and the upper edge of convex surface 85 and spacing preiection 86 have limited the scope that closed locking plate 8 rotates counterclockwise jointly, at this moment; Hold trigger action 41 again; Its convexity 43 promptly screws in the protruding draw-in groove 83 of trigger of closed locking plate 8, and trigger 41 can not be pressed, thereby has realized percussion locking.
When resetting: because SR is positioned at right-hand member (shown in Figure 6 the is left end) top of closed locking plate 7; Press SR; Closed locking plate 7 clockwise (being counterclockwise shown in Fig. 6) rotates; Lock projection 74 breaks away from closed locked groove 311, and propulsive mechanism 3 (shown in Fig. 6 for left) is to the right return initial position; In propulsive mechanism 3 moved to right process, the right-hand member of back assembly clamping plate 32 made percussion locking plate 8 clockwise rotate the state shown in Figure 10 of getting back to along zigzag convex surface 85 jack-up percussion locking plate 8.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
