The specific embodiment

Reach the aspect relevant for structure composition of the present utility model, technological means and effect, careful conjunction with figs. and embodiment further specify in the back:

As Fig. 1～shown in Figure 7, the instrument pincers of a kind of replaceable pincers jaw of the utility model, its first part 10 comprises two elongate handgrip 12,14, wherein handle 12 1 ends are lever 16, an opposite in addition end then is the chimeric end 18 of pincers jaw, same, handle 14 also is a lever 20 and the chimeric end 22 of a pincers jaw, and this handle 12,14 material is preferable with rigid metal material, the rigid material of right non-metallic material also can use, and a hollow chamber 24 is contained in handle 12 inside, has separated handle 12 and has made it to become two parallel embedding versions 26,28, and be entrenched in embedding version 26 with a pin 30, between 28, embedding version 26 in addition, respectively has a hole 32 on 28,34;

Under similar circumstances, handle 14 comprises a hollow chamber 36, wideer slightly than handle 12, so the reason of design is because handle 12 will slide in hollow chamber 36, hole 38 alignings on the embedding version 40 of hole 32 and handle 14, hole 42 alignings on the embedding version 44 of this hole 34 and handle 14 simultaneously, and be fixed between the embedding version 40,44 with pin 46.Precision architecture arrangement between handle 12,14 does not singly have only first part 10 of the present utility model in addition, also uses second part 48;

When hole 32 and hole 38 alignings, utilize pivot spigot 50 chimeric, hole 34 and hole 42 then utilize pivot spigot 52 chimeric, utilize rivet, trip bolt or snapping bolt as after the pivot spigot 50,52, because pivot spigot 50,52 is chimeric handle 12,14, therefore, handle engages with the mutual hinge of the form of scissors;

Merge the operating head that the chimeric end 18,22 of pincers jaw is first part 10, and the operating head between two pivot spigot 50,52 is to have one to be used for placing the inner cavity 54 that engages pincers jaw group 56, it is chimeric with the mutual hinge of scissors form that this pincers jaw group 56 comprises a pair of jaw, and this pincers jaw group 56 is to be to form first pair to link 58,60 and second pairs of bindings of jaw jaw 62,64;

This jaw 58 is to link with jaw 64 lockings with a core 66, jaw 60 then is to link with core 68 and jaw 62 lockings, this core 66 is provided with one and includes the sleeve 70 that penetrates path 72, and penetrate path 72 chimeric helical spring 74, the two ends of helical spring 74 respectively are connected to a metal balls 76, and this metal balls 76 is subject to and penetrates in the path 72 and can not break away from, yet helical spring 74 go all out move under this metal balls 76 can protrude in the side of pincers jaw group 56 slightly, when handle 12 inserts hollow chamber 36, metal balls 76 will be pushed into and penetrate path 72, when ball 76 and hole 32,34,38, during 42 alignings, 76 of metal balls can be promoted by the strength of helical spring 76 and give prominence to, this ring spring 78 is looped around the outside of sleeve 70 in addition, and the hole (not shown) that an end 80 of this ring spring 78 connects on the core 66, and the other end 82 has connected the hole 84 on the core 68, because ring spring 78 lasting generation active forces make this pincers jaw group 56 be remained on aperture position at this two holes (not shown) 84 and (consult Fig. 1, Fig. 4, Fig. 6), this ring spring 78 is entrenched in the annular groove 86 of core 66 in addition;

Jaw 58 be provided with a tool plane before grab face 88 and one row serrated face 90 the grasping object is more prone to, and jaw 60 also have a tool plane before grab face 92 and a gang saw flank of tooth 94 and also make the grasping object simpler and easy, grab face 88 before when object is clamped, being positioned at two, between 92, and when pincers jaw group 56 as Fig. 1 and when shown in Figure 6, wherein a metal balls 76 can be connected the aperture 96 on the embedding version 28,76 of another metal balls link to each other with aperture 98 on the embedding version 26, and aperture 96 and hole 42 are located along the same line, aperture 98 then is located along the same line with hole 32, this aperture 96,98 act as connects the metal balls 76 chimeric jaw groups 56 that firmly clamp, and makes it accurately to be positioned at hole 54;

The chimeric end 18 of pincers jaw has an inner plane 100, and the chimeric end 22 of pincers jaw also has similar inner plane 102, and inner plane 100 flushes applying with the lateral surface of jaw 58 or jaw 64; And plane 102 also flushes applying with the lateral surface of jaw 60 or jaw 62; Be provided with can lock outer recess 108 on jaw 58 of a pin 104 on this inner plane 100 in addition, can lock in the outer recess 108 of jaw 60 and also be provided with pin 106 on the inner plane 102;

When first pair of jaw 58,60 when externally extended position (this is the main use location of the utility model first part 10) and user force in lever 16,20, pincers jaw chimeric end 18,22 can make jaw 58,60 move and can grip object to the other side respectively, if the application of force is at the pliers of first part 10 always, pin 104,106 recesses 108,110 chimeric with it will make pincers jaw group 56 break away from handle 12,14; Unique pincers jaw group 56 that makes is from handle 12, the method that breaks away from 14 is not clamp any object and be positioned at as Fig. 1 at first part 10, aperture position shown in Figure 6, the user with hand with two jaws 58,60 can make pin 104 after forcing together, 106 by recess 108,110 break away from, be that available hand will clamp jaw group 56 from inner cavity 54 dial-outs (as shown in Figure 2), if the user inserts hole 54 up to metal balls 76 chimeric firmly apertures 96 again clamping jaw group 56 after pincers jaw group 56 rotations 1 80 degree again, 98 o'clock, this second pair of jaw 62,64 (these are needle nose pliers) promptly are positioned at the use location that can clamp object, jaw 64 has the recess 112 of chimeric pin 104, jaw 62 then has the recess 114 of chimeric pin 106, and this jaw 62 is provided with a folder object plane 116 with a gang saw flank of tooth 118, and jaw 64 also is provided with a folder object plane 120 with a gang saw flank of tooth 122;

First part 10 of the present utility model is for can manual operation being extracted pincers jaw group 56 and reinstall by hole 54 rapidly, change the structure of pliers, hence one can see that, utilize different complex pincers jaw groups 56 that many different types of pincers jaws can be arranged, by force in pin 30 extruding jaws 64 force in pin 46 extruding jaws 62 can closed jaw 58,60, when pincers jaw group 56 is positioned at opposite location (as shown in Figure 4), the strength of pin 30 is just corresponding to jaw 58, and the strength of pin 46 is then corresponding to jaw 60;

See also Fig. 8～shown in Figure 10, be the utility model second part 48, its structural principle is similar in appearance to the structure of aforementioned first part 10, but unlike pincers jaw group 56 replacement of can overturning, change and must insert hole 54 with single pincers jaw 126 or 128, the shape of pincers jaw 126 is same as jaw 58,60, pincers jaw 128 shape then with jaw 62,64 is identical, this pincers jaw 126 has jaw 130,132 and utilize metal balls 76 fixing in the same way, and pincers jaw 128 has jaw 134,136, and also by metal balls 76 chimeric apertures 96,98 and be attached in the hole 54, so this pincers jaw 126 can have various different structures and increase its scope of application.
