Detailed description of the invention
Core of the present utility model is to provide a kind of stiching instrument, and this stiching instrument can avoid the accident under severe impact to pull the trigger.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1 to Figure 10, according to the stiching instrument that an embodiment of the present utility model provides, comprise fixed handle 1, the firing handle 2 that can rotate relative to fixed handle 1, the assembly clamping plate be connected with firing handle 2, nail pushing plate 5 and the nail bin 6 being arranged on assembly clamping plate far-end, also comprise sliding pin 7, left jaw assembly 31, right jaw assembly 32, assembly clamping plate are provided with the clamping plate projection 441 with sliding tray 442, the at least side inwall of fixed handle 1 is provided with rail groove 101, sliding pin 7 passes sliding tray 442 and can move up and down in sliding tray 442, at least one end of sliding pin 7 is arranged in rail groove 101, the far-end of rail groove 101 is lower than the near-end of rail groove 101, nail pushing plate 5 is provided with the stopping means that can coordinate to limit nail pushing plate 5 with sliding pin 7 and move.When stopping means is spacing preiection 501, as shown in Figures 2 and 3, this stiching instrument is (see Fig. 6 and Fig. 8) when original state, because the spacing preiection 501 of nail pushing plate 5 is blocked by sliding pin 7, even if make stiching instrument under accidental impact or collision, nail pushing plate 5 also distally cannot move separately relative to assembly clamping plate, and therefore nail pushing plate 5 can not pull the trigger the staple in nail bin 6, thus ensure that stiching instrument can not surprisingly be pulled the trigger when severe impact.When using stiching instrument, front when holding firing handle 2 for twice (, first time holds firing handle 2 makes jaw be in semi-closed state, second time holds firing handle 2 makes jaw be in closure state), assembly clamping plate drive nail bin 6 and nail pushing plate 5 to travel forward simultaneously, now sliding pin 7 proximally slides to far-end along rail groove 101, as shown in Figure 9 and Figure 10, and sliding pin 7 is from the ionized motion of sliding tray 442 to bottom, thus the spacing preiection 501 of nail pushing plate 5 is no longer blocked by sliding pin 7.Therefore, when third time holds firing handle 2, firing handle 2 drives nail pushing plate 5 distally to move, and nail pushing plate 5 is relative to assembly clamping plate motion (now assembly clamping plate no longer distally move), then nail pushing plate 5 promotes the staple of nail bin 6 inside, completes the percussion of staple.
Further, as shown in Figure 4 and Figure 5, above-mentioned stopping means can be also stopper slot 502, and described sliding pin 7 is positioned at stopper slot 502 under the original state of stiching instrument.Stopper slot 502 is as stopping means, sliding pin 7 is stuck in stopper slot 502 thus, when pulling the trigger stiching instrument, front hold firing handle 2 for twice after, assembly clamping plate drive nail bin 6 and nail pushing plate 5 to travel forward, now sliding pin 7 proximally slides to far-end along rail groove 101, and sliding pin 7 is from the ionized motion of sliding tray 442 to bottom, thus sliding pin 7 skids off from the stopper slot 502 of nail pushing plate 5.Therefore, when third time holds firing handle 2, firing handle 2 drives nail pushing plate 5 distally to move, and nail pushing plate 5 is relative to the motion of assembly clamping plate, and nail pushing plate 5 promotes the staple of nail bin inside, completes the percussion to staple.Further, one of the proximal edge and remote edge of stopper slot 502 or both can be hypotenuse, namely tilt certain angle, moving down of sliding pin of being more convenient for (7).
Preferably, assembly clamping plate comprise left assembly clamping plate 43 and right assembly clamping plate 44, and laying respectively at nail pushing plate 5 left and right sides, left assembly clamping plate 43 and right assembly clamping plate 44 are provided with sliding tray 442, and left assembly clamping plate 43 are substantially relative with the sliding tray 442 of right assembly clamping plate 44.Sliding pin 7 runs through the sliding tray of left assembly clamping plate 43 and right assembly clamping plate 44.Two assembly clamping plate all arrange the stability that sliding tray 442 ensure that sliding pin 7.The shape of sliding tray 442 can be oval or rectangle or rhombus, also can be suitable for the sliding pin 7 smooth and easy shape moved up and down wherein for other is any.
Further, the both sides inwall of fixed handle 1 is respectively arranged with two corresponding rail grooves 101, and the two ends of sliding pin 7 are arranged in two rail grooves 101 respectively.Two rail grooves ensure that the stability that sliding pin 7 moves.
Further, the edge of rail groove can be stair-stepping.Further, the edge of rail groove can be also continuously smooth, makes sliding pin 7 more smooth in motor process, makes the feel of operator better.
Near-end herein refers to that, from the one end close to operator, far-end refers to from the one end away from operator.
Above stiching instrument provided by the utility model is described in detail.Apply concrete example herein to set forth principle of the present utility model and embodiment, but the explanation of above embodiment just understands principle of the present utility model and core concept thereof for helping, the restriction not to this utility model protection domain.Should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also carry out some improvement and modification to this utility model, these improve and modify and also fall in the protection domain of this utility model claim.
