Wherein, please cooperate and consult shown in Figure 3ly, indicator collet 21 is provided with chute 212, and is provided with the elasticity protrusion 216 that dwindles slot pitch at chute 212 middle parts.
Preferable; As shown in the figure, the overall structure of indicator collet 21 is preferably arc, and groove 211 is offered in the left side; 212 of chutes are arranged on the front face and/or rear surface of groove 211; Smooth and easy, steady that two chutes 211 more help moving is set, and one of them chute 212 inboard is provided with elasticity protrusion 216, and another chute 212 can be declined and establish elasticity protrusion 216.
In addition, also can the convexity 215 that reset be set, in the arranged outside indication icon or the scale printed layers of indicator collet 21 in the upper end of indicator collet 21.Indication icon or scale printed layers comprise at least two kinds of different indicator diagrams, and instruction content can be color, numeral, letter, Chinese character etc.
During installation, at first the lower end with indicator collet 21 is inserted in the groove of drag hook 22, and at this moment, the limited step 213 that is provided with on the baffle plate 222 of drag hook 22 and the indicator collet 21 offsets, and limited step 213 stops drag hooks 22 to clockwise rotate with respect to indicator collet 21.The bearing pin 24 that torsion spring 23 will be installed again is installed in the pin-and-hole 214,221 set on indicator collet 21 and the drag hook 22; One end of torsion spring 23 is against on the groove inner bottom surface of drag hook 22; The other end is stuck on the rib of indicator collet 21 lower ends; When drag hook 22 lower ends are stressed, compression torsion spring 23, drag hook 22 can be rotated counterclockwise with respect to indicator collet 21.
Please cooperate consult shown in Figure 4; A kind of straight line stiching instrument of this utility model; The indicating device 2 that comprises jaw, nail bin groupware, propulsive mechanism, firing handle 3, percussion connecting rod 1, SR 4 and this utility model, wherein, please cooperate consult shown in Figure 5; The rear end of percussion connecting rod 1 is connected with sliding pin 25, and sliding pin 25 is installed in the chute 212 of indicating device indicator collet.
Preferable, the arcuate structure of rear end for matching with the groove 211 of indicator collet 21 of percussion connecting rod 1 is provided with a pin-and-hole on arcuate structure, and sliding pin 25 promptly is fixedly connected with percussion connecting rod 1 through this pin-and-hole.And, shifting block 31 is set in the upper end of firing handle 3 at the indication icon or the corresponding indicating window convex lens of scale printed layers of stiching instrument afterbody installation with indicating device indicator collet 21.
In addition, the upper end of this utility model indicating device 2 should be positioned at the below of SR 4, and SR 4 is installed on the stiching instrument through the middle part rotating shaft, and at left lower end and bottom righthand side connecting rod is set respectively and resets and protruding 42 reset protruding 41 with indicating device.
Below to indicate as state at indicator collet 21 outsides printings green color bars and red ribbon, specify the course of action of this utility model, wherein: green color bars is positioned at the top, representes original state; Red ribbon is positioned at the below, expression percussion final state.
Please cooperate and consult Fig. 4, shown in Figure 5, when apparatus is in initial original state, the corresponding green color bars of indicating window convex lens, the expression stiching instrument is in original state.
Please cooperate and consult shown in Figure 6ly, hold firing handle 3, jaw is closed, and percussion connecting rod 1 moves, and indicating device 2 does not stress, and together rotates with percussion connecting rod 1 tail end, percussion connecting rod 1 forwards make position to stop after, indicating device 2 also stops with percussion connecting rod 1.
Please cooperate and consult shown in Figure 7ly, unclamp firing handle 3, get back in the initial position process in firing handle 3; Shifting block 31 on the firing handle 3 is against the upper surface of drag hook 22; And to its generation pressure, torsion spring 23 is compressed, and drag hook 22 rotates counterclockwise with respect to indicator collet 21.Shifting block 31 on the firing handle 3 slips over from drag hook 22 upper surfaces, and drag hook 22 is returned to original state under the effect of torsion spring 23, and at this moment, the shifting block 31 on the firing handle 3 is got back to the below of drag hook 22 from the top of drag hook 22.
Please cooperate and consult Fig. 8, shown in Figure 9, hold firing handle 3 once more and carry out firing action, the shifting block 31 on the firing handle 3 upwards promotes drag hook 22; Because the effect of limited step 213, drag hook 22 can not relatively move with indicator collet 21, therefore; Indicator collet 21 rotates counterclockwise with respect to percussion connecting rod 1 with drag hook 22, and sliding pin 25 slides to the bottom from the top of chute 212, in the sliding process; The elasticity protrusion 216 at sliding pin 25 extruding chutes 212 middle parts produces resistance to sliding, makes sliding pin 25 can send auditory tone cues clearly when arriving the bottom of chutes 212; The prompting percussion is accomplished; Simultaneously, because indicating device 2 has taken place to rotate counterclockwise, the indication that the indicating window convex lens is corresponding becomes red ribbon by the preceding green color bars of percussion.
When apparatus resets; Press SR 4; Indicating device on the SR 4 resets protruding 41, and to act on resetting of indicator collet 21 upper ends protruding 215, promotes indicating device 2 and clockwise rotate with respect to percussion connecting rod 1, and sliding pin 25 is got back to the top from chute 212 bottoms; Show in the indicating window convex lens to become green again, prompting indicating device 2 is accomplished and is resetted.Again the connecting rod of SR 4 is resetted afterwards and protruding 42 depress, promote percussion connecting rod 1 and reset.
The above; It only is the preferred embodiment of this utility model; Be not that this utility model 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 the protection domain of this utility model.
