Abstract
The utility model discloses a long handle locking pliers adopts the nut of inlaying at large handle rear portion to adjust the structure that the binding clip opened and shut the angle alive, has lengthened the pincers handle, has increased the arm of force, consequently is using this long handle locking pliers to carry out light laborsaving when pipe fitting or screw, nut are pulled the operation to can not only replace the hand vice to press from both sides the lock work piece and carry out the operation, light nimble in addition is fit for daily general maintenance installation operation requirement, has really played the function of spanner, pipe vice.
Description
The utility model relates to a kind of long handle locking pliers, belongs to wrench class hand-held tool.
Locking pliers is big because of jaw opens regulated quantity, and clamping force is big, and unique folder lock function has the effect of cutting pliers, hand vice, pipe vice, spanner, has become indispensable kind in the current hand-held tool.
But owing to locking pliers (refers to promote to throw off that handle is unblanked or promote to throw off handle outwardly unblanks in two kinds inwardly, locking pliers such as the round mouth of universal models, Ping Kou, cucurbit mouth, down together) because reasons in structure, length all is no more than 250mm (10 inches), this is big when pulling torsion to needing as switching pipe fitting, screw, nut, just seems hard especially.Modern is example with nominal dimension 250mm (10 inches) locking pliers, vice body always is about 225mm, remove the adjustment screw length that handle tail exposes, actual have only about 200mm, promptly be equivalent to adjustable wrench 200mm (8 inches) length, according to overlapping maximum screw, the nut pulled is M16, and this that is to say that for the screw more than the M16, nut locking pliers is just powerless.Therefore, can not really bring into play the effect of similar spanner, pipe vice although the workpiece that can reliable grip be reversed of locking pliers has the advantage that is difficult for skidding.If locking pliers is amplified in proportion, though length overall can reach more than the 300mm (12 inches), because whole heavy and inconvenience is used, particularly jaw is when opening, and size surpasses palm between big handle and the stalklet that struts, so with the hands also difficult kneading locker.
The purpose of this utility model provides a kind of long handle locking pliers, specification length can reach 400mm (16 inches), and existing jaw folder power is big, presss from both sides advantages such as thing can pin, light and flexible makes the effect of its real performance spanner, pipe vice to be fit to the requirement of daily general maintenance and installation switching operation again.
For achieving the above object, the utility model is done following improvement on known locking pliers architecture basics, and the variation of the binding clip folding angle of living is regulated by the nut that is embedded in big handle rear portion.When jaw does not press from both sides lock, the rotation nut, the screw clamp between support thick stick and nut moves with screw rod is forward and backward, because hinge is tied in the stalklet of the binding clip of living and is cut with scissors knot with the support thick stick again, and support thick stick afterbody and screw clamp hinge are tied, thereby have realized the variation of binding clip folding angle alive, and structure can add the handle of growing up thus.Because 250mm (10 inches) locking pliers clamping size can reach 46mm, be equivalent to M30 screw, nut size that 375mm (15 inches) adjustable wrench cover is pulled, therefore 400mm (16 inches) long handle Dali clipper head length is as long as suitably strengthen lengthening than 250mm (10 inches) Dali clipper head, the stalklet of all the other locker parts, disengagement handle, support thick stick etc. then need not strengthen, and just can reach the function with adjustable wrench same size size.
Owing to adopt such scheme, the utility model long handle locking pliers can not only press from both sides the lock workpiece and process operation, and because only by adding the handle of growing up, suitable increasing binding clip just can adapt to daily switching pipeline and screw, nut carry out small-sized machine installation and maintenance, really can bring into play the effect of pipe vice and spanner.
Below in conjunction with the embodiment of accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is first example structure figure of the present utility model.
Accompanying drawing 2 is A-A profiles in the accompanying drawing one.
Accompanying drawing 3 is another example structure of the utility model figure.
1. pincers 2. are decided binding clip 3. binding clip 4.5.6. rivet 7. extension springs 8. rivets 9. support thick sticks 10. screw clamps 11 rivets 12. little rivet 13. stalklets 14. screw rods 15. nuts 16. disengagement handles 17. big handle 18. torsion springs alive 19. holes among the figure.
Accompanying drawing 1 is that the utility model promotes inwardly to throw off handle and implements structure chart of the present invention on the locking pliers architecture basics of unblanking, among the figure explanation the utility model long handle locking pliers by decide binding clip 2, the binding clip 3 of living, extension spring 7, support thick stick 9, screw clamp 10, stalklet 13, screw rod 14, nut 15, throw off handle 16, handle 17, torsion spring 18, rivet 4,5,6,8,11 and little rivet 12 are formed greatly.Decide binding clip 2 and be fixed on the big handle 17 by rivet 4, the binding clip 3 of living is tied on big handle 17 by rivet 6 hinges.Live binding clip 3 around the rotation (1 of two jaw produce opening and closing to be changed) of rivet 6, is to realize by the nut 15 that rotation is embedded in big handle 17 rear portions.When pliers is in (when the center of rivet 8 is in diagram rivet 5,11 line of centres another sides) when not pressing from both sides the lock state, rotation nut 15, place the screw clamp 10 between support thick stick 9 and the nut 15 forward and backward mobile with screw rod 14, thus, support thick stick 9 and stalklet 13 produce interlock because of the hinge knot of rivet 11,8, by rivet 5 stalklet 13 and binding clip 3 hinges of living are tied again, thereby binding clip 3 alive is rotated around rivet 6.Above structure, big handle 17 can increase length as required.For guaranteeing the intensity behind big handle 17 embedding nuts 15, adopt the rectangle frame structure in the relevant position, and welding opposite joint (seeing accompanying drawing 2).Big handle tail is established hole 19 so that carry and extension is deposited.
Accompanying drawing 3 is that the utility model promotes outwardly to throw off handle and implements structure chart of the present invention on the locking pliers architecture basics of unblanking.Adopt welding to fix though as seen decide binding clip among the figure, the form of unblanking is also different with first embodiment, does not influence and adopts the nut 15 that is embedded in big handle rear portion to regulate the structure that binding clip 3 alive rotates around rivet 6.
