Description

A kind of multifunctional pliers

Technical field

The utility model relates to a kind of multifunctional pliers, possesses wires such as shearing iron wire, steel wire, clamps metal bar, the nut function that tights a bolt, and is specially adapted to the occasion of tightening the tubing nut fast continuously.

Background technology

Kind, the quantity of the entrained instrument of Engineering operating personnel is often more, weight is heavier; On the other hand, when the Engineering operating personnel runs into demolition, installation tubing nut, typically use open-end wrench and carry out demolition, installation, employed open-end wrench can not carry out continuously, tighten fast or unclamp the tubing nut, inefficiency.

CN200510038740.5 discloses a kind of quick-locking water pump pliers, comprise left caliper and right caliper body, a left side, right caliper body is made up of binding clip and pincers handle respectively, offer bar hole between the binding clip of left caliper and the pincers handle, the bar hole both sides are provided with tooth bar, 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, hollow bolt middle part vertically offers slotted eye, be provided with sliding part in the slotted eye, its the inner is provided with gear, be provided with spring between the shrinkage pool of gear end and the nut cap, the other end of sliding part passes slotted eye and connects with button, and this pliers can carry out quick adjustment to the jaw relative position of pliers, serviceability is improved significantly, but function is comparatively single.

CN97213496.4 discloses a kind of multifunctional pliers, and these pincers are made up of inside and outside two pincers sheets, and are linked together by bearing pin, clamp outward and are processed with centre pilot chute, limit portion chute, a plurality of circular arc zigzag groove on the sheet.Make up tong and be processed with a circular arc on the sheet and protrude serrated teeth.During work, serrated teeth embeds in the zigzag groove.When need changing the jaw opening size, serrated teeth and zigzag groove are thrown off, and move the sheet that makes up tong and to change the jaw opening size, to finish clamping plurality of specifications size securing member along clamping sheet centre pilot chute direction outward.That this instrument still only can be realized is fastening, demounting bolt, nut function, and the functional diversities of being unrealized.

CN99256443.3 discloses a kind of multi-purpose type pliers, comprise handle, caliper and connecting axle, caliper two heads respectively are one tiny " L " shape, and the whole relative inner face of caliper all has cutting edge until " L " shape part termination, and is V-shaped after the two caliper inner face cutting edge interlocks.Filament vertically be clamped, pull out or be cut off to the curved mouth of " L " shape that this pliers is tiny can in the mouth of pipe of radius less than the degree of depth; Simultaneously, the toothed breach that has of caliper connecting axle rear end can make the operator clamp and turn tiny nut with the clamping power of pliers.This pliers is used for special purpose, and the structure that turns nut of its design can only be used for tiny nut, and uses inconvenience.

In sum, existing pliers instrument does not have obviously to reduce kind, quantity, the weight of the entrained instrument of Engineering operating personnel, particularly do not realize tightening continuously, fast or unclamping the tubing nut, reduced labourer's labour intensity, improved functions such as labor productivity.
