Quick-locking water pump pliers

Technical field

The utility model belongs to the hardware ﹠ tools field, relates to a kind of water pump pliers of locking fast that is used for.

Background technology

Existing pliers generally all is made up of the caliper of a pair of mutual correspondence, and caliper is made up of binding clip and pincers handle respectively, is provided with the hinge tipping and puts between binding clip and pincers handle.During use,, two calipers are rotated around the hinge contact, thereby can make binding clip that object is produced chucking power by the pincers handle is applied active force.But because the structure of this pliers is comparatively simple, and the maximum open scope of its binding clip fixes, and therefore, its scope of application is very restricted.

Summary of the invention

The purpose of this utility model is to provide a kind of quick adjustment binding clip relative position that carries out, thereby realizes the different quick-locking water pump pliers that need that use.

For realizing the purpose of this utility model, a kind of quick-locking water pump pliers, comprise left caliper and right caliper body that a pair of mutual hinge connects, left caliper is made up of binding clip and pincers handle, right caliper body is made up of binding clip and pincers handle, offer bar hole between the binding clip of described left caliper and the pincers handle, the both sides of bar hole are provided with the tooth bar of mutual correspondence, offer hinge hole between the binding clip of right caliper body and the pincers handle, it is fastening that hollow bolt passes bar hole and hinge hole and nut cap, the axial middle part of hollow bolt offers slotted eye, be provided with sliding part in the slotted eye, the inner of sliding part be provided with can with the tooth bar meshed gears, be provided with spring between the shrinkage pool of gear face and the inner face of nut cap, the slotted eye that the other end of sliding part passes hollow bolt connects with button.

The utility model has the advantages that: can carry out quick adjustment to the jaw relative position of pliers, serviceability is improved significantly.

The specific embodiment

As Fig. 1,2, shown in 3 and 4, a kind of quick-locking water pump pliers, comprise left caliper 1 and right caliper body 2 that a pair of mutual hinge connects, left caliper 1 is made up of binding clip 11 and pincers handle 12, right caliper body 2 is made up of binding clip 21 and pincers handle 22, offer bar hole 13 between the binding clip 11 of described left caliper 1 and the pincers handle 12, the both sides of bar hole 13 are provided with the tooth bar 14 of mutual correspondence, offer hinge hole 23 between the binding clip 21 of right caliper body 2 and the pincers handle 22, hollow bolt 3 passes bar hole 13 and hinge hole 23 is fastening with nut cap 4, the axial middle part of hollow bolt 3 offers slotted eye 31, be provided with sliding part 5 in the slotted eye 31, slotted eye 31 is not a circular hole, therefore sliding part 5 can not rotate slotted eye 31 in, can only be along the direction slip of slotted eye 31, the inner of sliding part 5 be provided with can with tooth bar 14 meshed gears 51, be provided with spring 6 between the shrinkage pool of gear 51 end faces and the inner face of nut cap 4, the slotted eye 31 that the other end of sliding part 5 passes hollow bolt 3 connects with button 7.

This quick-locking water pump pliers is when normal the use, sliding part 5 is in the ejection state under the elastic force effect of spring 6, button 7 then stretches out from the slotted eye 31 of air bolt 3 with an end of sliding part 5, the gear 51 of sliding part 5 other ends meshes with the tooth bar 14 of left caliper 1 at this moment, hollow bolt 3 just can not slide in the bar hole 13 of left binding clip, operate left and right caliper 1,2 this moment just can make binding clip 11,21 foldings, is used for locking and pulls object.

If adjust binding clip 11,12 openings of sizes when initial, as long as pin button 7, make sliding part 5 overcome the elastic force effect of its contained spring 6, sliding part 5 can inwardly slide along the slotted eye 31 of hollow bolt 3, when sliding into to a certain degree, the gear 51 of sliding part 5 the inners just can break away from engagement with tooth bar 14, at this moment, right caliper body 2 just can be along with hollow bolt 3 slides arbitrarily in the bar hole 13 of left caliper 1, and when being adjusted to desired location, release button 7 once more, sliding part 5 resets under the reaction of spring 6, gear 51 meshes a left side with tooth bar 14 again, right caliper body 1, locking device between 2 is reorientated them, and this water pump pliers can normally use again.
