The main working principle of the disposable clip applier is shown in figure 4: when a practitioner presses down the handles at two sides with fingers, the handles rotate inwards to generate inward compression force on the push sheet 10 through the push sheet fixing pins 13, the push sheet 10 converts the inward compression force into forward thrust on the push pipe 7 and the return spring 14 through the push sheet connecting pins 12, the push pipe 7, the push head 4 and the connecting shaft 2 are connected together through the push pipe connecting pins 6, so that the forward thrust of the push pipe is transmitted to the push head, and the front end of the spring is propped against the U-shaped boss of the shell 8. Finally, the return spring 14 is compressed, and the push pipe 7, the connecting shaft 2 and the push head 4 move forwards. When the pushing head 4 moves forwards, the two sides of the forceps head 1 of the disposable forceps are extruded, and because the two sides of the front end of the pushing head 4 are provided with clamping grooves (clamping grooves are shown in figure 14) for correcting and fixing the forceps head, the forceps head 1 is clamped in the clamping grooves, the clamping grooves can position and correct the forceps head, therefore, when the push head 4 extrudes the two sides of the disposable clip applier head 1, the disposable clip applier head 1 can not rotate or move with bad effect, only can move inwards as shown in figure 4, the titanium nail clamped on the disposable clip applier head can be closed together with the head, the titanium nail can be ensured to be completely closed by designing and researching the included angle on the inner side of the binding clip from the front end when the titanium nail is ensured to be closed, and the titanium nail can be ensured to be completely closed by the shape and the thickness of the binding clip and the forward pushing distance of the pushing head and other factors, and the closed titanium nail is ensured to be not staggered by the symmetry degree of the clamping nail grooves on the two sides of the binding clip. When the titanium nail is closed and the handle is released, the return spring 14 which is compressed before can be bounced, and the front end of the return spring 14 is the U-shaped boss of the shell 8, so the return spring 14 can only be bounced backwards, the push pipe 7, the connecting shaft 2 and the sleeve head 4 can move backwards by the thrust generated when the return spring 14 is bounced, at the moment, when the extrusion force of the sleeve head 4 does not act on the disposable clip pliers head 1, the disposable clip pliers head can be opened towards two sides under the elastic recovery action of the disposable clip pliers head, the backward thrust generated when the return spring 14 is bounced can also enable the push sheet 10 to generate outward supporting thrust, and the outward supporting thrust of the push sheet 10 can enable the handle 9 to generate outward rotating motion. When the return spring 14 pushes the push tube 7, the connecting shaft 2 and the push head 4 to move backwards, the push tube 7 finally touches the adjusting bolt 15, at this time, the push tube 7, the connecting shaft 2 and the push head 4 stop moving backwards, the opening of the disposable clip head 1 returns to the state before nail closing, the handle 9 and the push piece 10 also stop moving and return to the position and state before nail closing, at this time, the return spring 14 returns to the length before nail closing but still has a certain amount of compression (namely, the compression amount also exists before nail closing), the elastic force generated by the compression amount can enable the disposable clip applier to be in a backward stress state all the time, so that the handle 9 and the push piece 10 are stressed all the time and cannot be loosened or shaken, and similarly, the clip head 1 of the disposable clip applier can also be extruded by the push head 4 by a certain amount and is in a stress state all the time, and the clip can not be shaken to move towards two sides during clipping to hold the titanium nail and firmly guarantee that the titanium nail cannot fall off.
