Detailed description of the invention
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in Figures 2 to 11, a kind of Endo-GIA of assembly band cutter, comprises cover plate 1 and assembly clamping plate 2, and assembly clamping plate 2 front end is provided with nail bin 6, and assembly clamping plate 2 rear end is arranged can the cutter 3 of movement in nail bin 6.
The rear end of nail bin 6 is provided with cutter cover 7, and cutter cover 7 is formed through rotating shaft 8 and nail bin 6 and is rotationally connected, and this rotating shaft 8 being provided with torsion spring, forming resilient engagement between cutter cover 7 and nail bin 6 through reversing, and the rear end of cutter cover 7 forms lock cutter hook 71.
Cutter 3 comprise cutting knife 5 and push-pull piece 4, the rear end of cutting knife 5 and the mutual clamping in front end of push-pull piece 4, and the upper end of cutting knife 5 is provided with the lock edge of a knife 53 for matching with the lock cutter hook 71 of cutter cover 7.
Sickle is when dispatching from the factory, and cutter cover 7 is in pressing down shape, and the lock cutter hook 71 of cutter cover 7 is connected in the lock edge of a knife 53 of cutting knife 5.
As shown in Figs. 8 to 11; Fig. 8, cutting knife 5 is in original position, and cutting knife 5 is stuck; Fig. 9, cutting knife 5 is promoted forward by push-pull piece 4, and cutting knife 5 and cutter cover 7 break off relations, and cutter cover 7 overturns counterclockwise and upsprings under torsion spring effect; Figure 10, after percussion completes, cutting knife 5 is pulled backward to cutter cover 7 place by push-pull piece 4, and cutter cover 7 overturns clockwise under cutting knife 5 drives; Figure 11, when cutting knife 5 is through after cutter cover 7, returns to closure state at the effect lower cutter cover 7 of torsion spring, and now cutting knife 5 cannot driven forward, prevents cutter 3 two percussions, achieves the function of insurance.
