The specific embodiment
The present invention has disclosed a kind of linear type closer; As shown in Figure 1; Consistent with prior art, said linear type closer comprises that pivot is arranged on the handle 1 on the shell (not shown), and said handle 1 promotes nail bin 3 through bin pushing rod 2; Make said nail bin 3 with respect to nail anvil 4 motions that are fixed on the outer casing stand, be arranged on tissue between the two thereby be fixedly clamped.Said nail bin 3 is with respect to nail anvil 4 motion the time, and anti-overflow pin push rod 9 moves to nail anvil 4 with ejector pin bar 8 together, is arranged on that anti-overflow pins in the nail bin 3 are released by said anti-overflow pin push rod 9 this moment and in alignment with said nail anvil 4.Said ejector pin bar 8 can be arranged in the cavity of said anti-overflow pin push rod 9 relatively slidably.
Said handle 1 also connects with ejector pin bar 8 through a percussion brake(-holder) block 6, and the suturing nail that said ejector pin bar 8 will be arranged in the nail bin 3 in the process of motion is pushed out of outside the nail bin 3, and said support is provided with an interlocking block 5; When said ejector pin bar 8 promotes the pushing slice of nail motion forward; Pushing slice of nail and then will follow closely and pull the trigger out, the ejector pin bar resets then, and pushing slice of nail is left on the position after the percussion; Interlocking block on the support is after the restriction that loses pushing slice of nail at this moment; Put empty location deflection to the below of pushing slice of nail, thereby stop the ejector pin bar to travel forward, reached the effect that prevents that apparatus from being pulled the trigger by secondary.The rear end of linear type closer also is provided with a release-push 7, after seamed, pushes this release-push 7, and said nail bin, bin pushing rod, ejector pin bar all can be retreated to initial position together.
