Setting be more advantageous to the 51 transverse shear stress safety block 61 of proximal end of cutter 5 and be moved to the third place.
Fig. 9 shows the structural schematic diagram of the section B-B after cutter reset.As shown in figure 9, being back to first in cutter 5
During position, after cutter 5 is moved to the position for no longer generating interaction force with safety block 61, two pieces of safety blocks 61 it
Between lose the transverse shear stress of cutter 5, be moved again to the 4th position under the elastic force effect of elastomeric element (bullet block 62), be barred from
Between the first position and the second position.Due to the transverse gage for being smaller than cutter 5 between two safety blocks 61, and protect
The proximal end of dangerous block 61 does not have guide portion, and therefore, if to carry out secondary percussion, safety block 61 can stop cutter 5 by first
It sets to the second position and moves so that instrument can not carry out secondary percussion, could normally be fired after the nail bin only more renewed.
And when the nail bin more renewed, the convex block 32 of the percussion block of new nail bin can lead to above the spacing between two pieces of safety blocks 61
The guiding for crossing third inclined-plane 612 is squeezed between two pieces of safety blocks 61, while safety block 61 being forced to again return to the third place, that is, is returned
It is back to state as shown in Figure 5.Therefore, if the nail bin 2 not renewed, safety block 61 can not be entered the second limiting slot by transverse shear stress
14, then cutter 5 is stopped by safety block 61, can not be moved again to the second position, prevent nail-head component from not replacing to play
