The specific embodiment
The present invention has disclosed a kind of straight line stiching instrument, and is consistent with prior art as shown in Figure 1, comprising: housing 1, be fixed in support 2 on the housing 1, be arranged at the nail anvil 3 of support 2 far-ends, and a pivot is arranged at the percussion handle 4 on the support 2.Straight line stiching instrument of the present invention also comprises a nail bin groupware 5, and is concrete with reference to shown in Figure 2, and described nail bin groupware comprises that plug-in is located at the nail bin frame 6 of rack far end, is provided with the ejector pin film perforation 8 that passes for pushing slice of nail 7 in the described nail bin frame.The shape of described pushing slice of nail 7 with arrange all consistent with prior art, for inside and outside two row staggered.
Be provided with a columniform rotary-type nail bin 9 in the described nail bin frame 6, be evenly equipped with at least 2 groups nail hole 10 on the periphery of described rotary-type nail bin, in this example be 3 groups, namely every group of center of circle angle of following closely between the hole 10 is 60 °, and one group of nail hole 10 is 2 staggered rows.Every group of nail hole 10 all is arranged with on blow fermentation 16.Be connected in the columniform periphery in the described percussion face 16.
All be placed with suturing nail in each nail hole 10, each nail hole 10 is through the periphery of rotary-type nail bin 9.Be provided with between described rotary-type nail bin 9 and the nail bin frame 6 be used to the rotating shaft mechanism that described rotary-type nail bin 9 is rotated with respect to nail bin frame 6, and be used for optionally making described wherein one group nail hole 10 and described ejector pin film perforation 8 position-limit mechanism one to one.Described rotating shaft mechanism and position-limit mechanism are formed selecting apparatus of the present invention.
Specifically, described rotating shaft mechanism comprises two rotating holes 11 being located on the described nail bin frame, and the corresponding rotating shaft 12 of being located at two end faces of described rotary-type nail bin 9 respectively, and described rotating shaft 12 can insert in the described rotating hole 11.Certainly, the position of rotating hole 11 and rotating shaft 12 also can exchange, and certainly, also can adopt the pin-and-hole structure except disclosing in this case, still can adopt other pivot structures, for example increases bearing etc.
Described position-limit mechanism comprises the groove of being located on the described nail bin frame 6 13, and the corresponding position rotating muscle 14 of being located at the end face of described rotary-type nail bin 9.In this example, be provided with two extensions 15 on the described nail bin frame symmetrically, respectively be provided with a groove 13 on the facing surfaces of described two extensions 15, described groove 13 on two extensions 15 respectively is coplanar.Described each groove 13 all passes described rotating hole 11, and described each position rotating muscle 14 all passes described rotating shaft 12.In this example, every group of nail hole 10 namely rotates muscle 14 in a corresponding location.In the time of in described position rotating muscle 14 snaps in described groove 13, described wherein one group nail hole 10 is corresponding one by one with described ejector pin film perforation 8.
Preferably, as shown in Figure 3, the cross section of described position rotating muscle 14 comprises a right-angle side 141 and a round edge 142 respectively.Like this, when described rotary-type nail bin 9 rotates, only allow to enter in the groove 13 from round edge 142 1 sides, so just prevented the reversing of described rotary-type nail bin 9.
The operating process of present embodiment below underdraws.
Under the original state, have one group of nail hole 10 corresponding with described ejector pin film perforation 8, the relative formative tissue with nail anvil of percussion face 16 this moment is pulled the trigger regional, and described percussion face 16 is all parallel with relative nail anvil face 17, ejector pin frame surface 18 immediately.When needs were pulled the trigger, pushing slice of nail 7 can directly enter in ejector pin film perforation 8 and the nail hole 10, and the suturing nail in the nail hole 10 is pushed out of outside the nail hole 10.By clockwise or counterclockwise direction rotating wheel formula nail bin 9, direction of rotation is decided on the place of round edge 142 then.After snapping in the described groove 13 with next group nail hole 10 corresponding position rotating muscle 14, then instantly this group to follow closely hole 10 namely corresponding with described ejector pin film perforation 8.At this moment just can continue percussion.In like manner, the suturing nail in the 3rd group the nail hole is pulled the trigger after the same method.After the suturing nail in three groups of nail holes is all finished by percussion, have the prompting of color or sound this moment, at this moment just need to change whole nail bin groupware.
Fig. 4 has disclosed the second embodiment of the present invention, is to be evenly equipped with 2 groups of nail holes 10 on the periphery of described rotary-type nail bin 9 with the difference of first embodiment, and namely the center of circle angle between every group of nail hole 10 is 90 °, and all the other all features are all identical with first embodiment.The present invention can finish the repeatedly function of percussion like this.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
