Utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition overcomes the defect that existing pliers uses effort, function singleness, provides a kind of multifunctional force saving to clamp.

For achieving the above object, multifunctional force saving pincers of the present utility model, comprise the first caliper, second caliper, described first caliper comprises the first anterior binding clip, first neck at middle part, first lever at rear portion, described second caliper comprises the second anterior binding clip, second neck at middle part, second lever at rear portion, the first described binding clip is provided with the first shear blade, the second described binding clip is provided with the second shear blade, the first described neck and the second neck are through pinned connection, it is characterized in that: described bearing pin departs from described first neck, the geometric center of the second neck is near described first binding clip, the position of the second binding clip, the first described caliper, second caliper is provided with the Function-expandable architecture cooperatively interacted.

As optimization technique means: described Function-expandable architecture comprises the half round cut of the correspondence be divided on described first binding clip, the second binding clip, the half round cut of described correspondence forms wire stripping hole when described first binding clip, the second binding clip close up.

As optimization technique means: Function-expandable architecture comprises groove, the projection of the correspondence be divided on described first binding clip, the second binding clip, in the groove described in the projection described in when described first binding clip, the second binding clip close up embeds.

As optimization technique means: the external diameter that the first described neck and the second neck set up screwed hole separately, shearing perforation and the diameter of described shearing perforation are greater than described screwed hole, the first described binding clip and the second binding clip close up shearing perforation described in process corresponding described in screwed hole.

As optimization technique means: this labor-saving plier is cutting pliers or diagonal cutting pliers.

The beneficial effects of the utility model are: by bearing pin is departed from the first neck, the second neck geometric center near the position of the first binding clip, the second binding clip, reduce resistance arm when shearing the object such as steel wire, use laborsaving; And on the first caliper, the second caliper, be provided with the Function-expandable architecture cooperatively interacted, as wire stripping can be realized, and crimps, cut off the functions such as screw.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described further.

As Fig. 1-2, shown in 3-4, multifunctional force saving pincers of the present utility model, comprise the first caliper 01, second caliper 02, first caliper 01 comprises the first anterior binding clip 11, first neck 12 at middle part, first lever 13(first lever at rear portion does not all show), second caliper 02 comprises the second anterior binding clip 21, second neck 22 at middle part, second lever 23 at rear portion, first binding clip 11 is provided with the first shear blade 14, second binding clip 21 is provided with the second shear blade 24, first neck 12 is connected through bearing pin 03 with the second neck 22, bearing pin 03 departs from the first neck 12, the geometric center of the second neck 22 is near the first binding clip 11, the position of the second binding clip 21, first caliper, second caliper is provided with the Function-expandable architecture cooperatively interacted.The lap that described first neck, the second neck are determined when bearing pin 03 relatively rotates by the first caliper 01, second caliper 02.

Concrete, Function-expandable architecture comprises the half round cut of the correspondence be divided on the first binding clip 11, second binding clip 21, and corresponding half round cut forms wire stripping hole 04(see Fig. 1, Fig. 3 when the first binding clip, the second binding clip close up).During wire stripping, open two levers, cable is put into the corresponding wire stripping hole in aperture, two levers of holding with a firm grip make it mutually draw close, and the insulation sheath of cable can be cut off, and cut-off insulation sheath can be departed from cable core by tractive cable.

Function-expandable architecture also comprises groove 25, the projection 15 of the correspondence be divided on the first binding clip 11, second binding clip 21, and when the first binding clip 11, second binding clip 21 closes up, projection 15 embeds (see Fig. 1, Fig. 3) in groove 25.This structure realizes crimping function: open two levers, and will the object of crimping be needed to be placed in groove position, two levers of holding with a firm grip make it mutually draw close, and projection pressure holding makes object realize crimping to groove internal strain by force on object.

(external diameter of screw thread is and the imaginary cylinder diameter coincided at the bottom of external screw thread crest or internal thread tooth the external diameter that first neck 12 and the second neck 22 set up screwed hole 26 separately, shearing perforation 16 and the diameter of shearing perforation 26 are greater than screwed hole 26.The nominal diameter of screw thread and external diameter, also claim large footpath), the first binding clip 11 closes up the corresponding screwed hole of shearing perforation in process with the second binding clip 21.Realize accordingly cutting off bolt function: open two levers overlapping with screwed hole to shearing perforation, by the bolt for cutting off by screwed hole, need the part sheared to extend in shearing perforation, two levers of holding with a firm grip make it mutually draw close, screwed hole and shearing perforation misplace and produce shearing force, cut off bolt.

This labor-saving plier can show as cutting pliers or diagonal cutting pliers.
