See also Fig. 3, Fig. 4, the clamping orientation tool of the utility model first embodiment includes first lamellar body 1, second lamellar body 2, first flexible member 3 and second flexible member 4 etc. partly.

This first lamellar body 1 is by on the identical appearance, following lamellasome 1a, 1b forms, be provided with a pair of jaw end 11a, 11b, a pair of handle end 13a, 13b and a pair of central neck 12a, 12b, and at this neck 12a, 12b is respectively equipped with a teeth groove 14a, 14b, this teeth groove 14a, 14b is respectively equipped with a ratchet face 15a, 15b and a pair of sliding surface 16a, 16b, on above-mentioned first lamellar body, 1 handle end 13, following lamellasome 1a, be provided with an interlayer body 17 between 1b, this interlayer body 17 is being provided with a retaining hole 171 in the face of second lamellar body, 2 about sides, in the present embodiment, on being somebody's turn to do, following lamellasome 1a, 1b is to combine with pin 18 to fix with interlayer body 17, and at this interlayer body 17 near neck 12a, 12b establishes the position opening 172, and makes a pin 18 be revealed in this opening 172.

Above-mentioned second lamellar body 2 is equally also by on the identical appearance, following lamellasome 2a, 2b forms, be provided with a pair of jaw end 21a, 21b, a pair of handle end 23a, 23b and a pair of central neck 22a, 22b, and at this neck 22a, 22b is provided with a pair of locating hole 28a, 28b, be embedded in this locating hole 28a with an inserted tooth 24, among the 28b, in the present embodiment, this locating hole 20a, 20b and inserted tooth 24 have identical appearance, this inserted tooth 24 also has a ratchet face 241 and a sliding surface 242, and with locating hole 28a, the chimeric contact-making surface of 28b is established the matsurface 243 that has the roller flower, can be closely chimeric, this inserted tooth 24 is located at the teeth groove 14a of first lamellar body 1, among the 14b, make first and second lamellar body 1,2 cross-shaped attitudes, and inserted tooth 24 can be at teeth groove 14a, slide among the 14b.And be provided with a pair of card division 27a, 27b in the face of opening 172 positions of first lamellar body, 1 interlayer body 17 at neck 22a, 22b, between upper and lower lamellasome 2a, the 2b of the handle end 23 of second lamellar body 2, be provided with an interlayer body 25, this interlayer body 25 is provided with a breach 251 in the side in the face of first lamellar body 1, in the present embodiment, this upper and lower lamellasome 2a, 2b also combine fixing with interlayer body 25 with pin 26.Two above-mentioned interlayer bodies also can be spirally connected with first and second lamellar body respectively.

And, the retaining hole 251 that is positioned at second lamellar body 2 than the retaining hole 171 of first lamellar body 1 more near neck 12a, 12b.

Above-mentioned two retaining holes 171,251 are positioned at the adjacent inboard of first and second lamellar body 1,2 handle end 13a, 13b, 23a, 23b, first end 31 and second end 32 of rabbeting first flexible member 3 respectively, in the present embodiment, first flexible member 3 is a torsionspring, this first end 31 and second end 32 bend a bent angle respectively, so as to embed two the retaining holes 171,251 in and unshift.Strut so as to the handle end 13,23 that makes present embodiment, and make jaw end 11,21 present the original state of maximum open.

The first above-mentioned flexible member can be a leaf spring, also can be a helical spring.

4 card division 27a, 27b that are engaged in second lamellar body 2 with its first end 41 of above-mentioned second flexible member, second end 42 then engages with pin 18 in first lamellar body, 1 interlayer body, 17 openings 172, in the present embodiment, second flexible member 4 is helical springs, and the elastic force of second flexible member 4 is less than the elastic force of first flexible member 3.

See also Fig. 5, by above-mentioned structure, when desire is used the tool holding object 5 of the utility model first embodiment, need force in handle end 13,23, when object 5 external diameters less than jaw end 11, during 21 extended distances, because second flexible member, 4 elastic forces are less than first flexible member 3, make the stressed earlier and stretcher strain of second flexible member 4, therefore, in relative motion, when first lamellar body 1 is set transfixion, first lamellar body 1 that second lamellar body 2 owing to need supports by first flexible member 3 and the distance of second lamellar body 2 remain unchanged under the situation, just serve as that axle changes a fulcrum A with the retaining hole 171 of first lamellar body, 1 interlayer body 17, inserted tooth 24 is slided with the drawing direction of arrow in teeth groove 14, make jaw end 21 move to shorten spacing and contact with object 5 outer rims to the jaw end 11 of first lamellar body 1.

See also Fig. 6, above-mentioned teeth groove is being established a ratchet face in the face of the jaw extreme direction, and above-mentioned inserted tooth is at the ratchet face that also is provided with a correspondence in the face of teeth groove ratchet face direction.When jaw end 21 with after object 5 contacts, continue the application of force, when this application of force during greater than the elastic force of first flexible member 3, just oppress first flexible member 3 and make its flexural deformation, at this moment, second lamellar body 2 serves as that axle changes fulcrum B with this jaw end 21 and object 5 contact points just, inserted tooth 24 is rotated with the drawing clockwise direction, and make ratchet face 241 be embedded in the ratchet face 15 of teeth groove 14, and be fulcrum just afterwards with this inlay card position, compress handle end 13,23 with clamping article 5.

After removing the application of force, the ratchet face 241 of inserted tooth 24 is subjected to the effect of first and second flexible member 3,4 elastic-restoring forces immediately and separates with the ratchet face 141 of teeth groove 14, makes this two jaws end 11,12 be returned to the original state of maximum open.

It should be noted that: the utility model first embodiment is poor with the elastic force of two kinds of different elastic force flexible members, in order to clamping the object of different size, and by inserted tooth 24 to reach predetermined effect of the present utility model:

1, assembling rapidly.Because locating hole 28 contour shapes of second lamellar body 2 are identical with inserted tooth 24, therefore when assembling, only need directly squeeze in the locating hole 28 and get final product, utilize matsurface 243 increases of inserted tooth 24 and the frictional force of locating hole 28, avoid axial disengaging.

2, fast moving.Because inserted tooth 24 has a sliding contact surface with teeth groove 14, therefore, when the beginning application of force, inserted tooth 24 just produces relative slip with teeth groove 14, so as to the spacing of rapid adjustment jaw end 11,21 so that contact with object 5.

3, clamping is laborsaving.Because inserted tooth 24 has a ratchet contact-making surface with teeth groove 14, therefore, when jaw end 11,12 with after object contacts, this inserted tooth 24 just is that fulcrum produces relative rotation in teeth groove 14 with the contact point, ratchet 24 is embedded in the teeth groove 14, is re-used as a balance pivot whereby and makes 21 pairs of objects 5 of jaw end play the effect of pivot folder.

See also Fig. 7, the utility model second embodiment also can be provided with a wavy teeth groove ratchet face, cooperates the inserted tooth of a semicircle, can make inserted tooth equally when rotating, end face with semicircle inserted tooth is embedded in the wavy teeth groove, reaches the same function of compeling clamping article of supporting.

See also Fig. 8 and Fig. 9, the 3rd embodiment of the present utility model is located at the structure of above-mentioned second embodiment on a kind of slip-joint pliers, makes these slip-joint pliers reach the same effect of sliding fast and rotating clamping article with first and second embodiment.

Certainly, except that above-mentioned three kinds of embodiment of the present utility model, still have many examples, therebetween the only variation on the details.Especially, be located at the torsionspring of the handle end of first, second and third embodiment, replaceable is a leaf spring or a helical spring.
