Abstract

The utility model discloses multifunctional labor-saving pincers. The pincers comprises a first pincer body and a second pincer body which are symmetrically shaped and oppositely arranged, wherein each pincer body includes a pincer handle, a pincer gill and a pincer head; a small clamping part and a small cutting edge cutting part are arranged on the pincer heads; the two pincer bodies are movably connected at the pincer gills through a pin shaft, and the connecting point is arranged on the pincer gills in a position deviated from the geometrical center of the pincer gills and close to the pincer heads; a large cutting edge is arranged on each pincer gill in a position close to each pincer handle respectively, and the two large cutting edges are matched with each other to form a large cutting edge cutting part; and an arc-shaped bump is arranged on each pincer handle in a protruding manner respectively, and the two arc-shaped bumps are oppositely arranged and matched with each other to form a large clamping part. The connecting point of the two pincer bodies is arranged in the position deviated from the geometrical center of the pincer gills and close to the pincer heads, so as to synchronously reduce the resisting arm and enlarge the power arm for the labor-saving effect; and the large cutting edge cutting part and the large clamping part are additionally arranged on the pincers, thereby achieving higher practicability.

Description

A kind of multi-functional laborsaving pliers

Technical field

The utility model relates to a kind of multi-functional laborsaving pliers.

Background technology

Pliers is machinery assembling, the maintenance tool of using always, using that pliers is sheared, all need clamp during clamping and apply very big power on the handle at it, existing pliers is in order to reach the labour-saving purpose, conventional method is that the pincers handle is extended, to cause use inconvenient and the pincers handle is long, and make it in narrow space, not use.

The utility model content

At the problem that existing situation exists, the purpose of this utility model is to improve the improved multi-functional laborsaving pliers of a kind of structure.

For achieving the above object, a kind of multi-functional laborsaving pliers of the utility model, comprise shape symmetry, first caliper and second caliper that direction is opposite, two calipers comprise pincers handle, the pincers gill and binding clip respectively, binding clip is provided with little clamping part and little cutting edge cut part, two calipers flexibly connect by bearing pin mutually at pincers gill place, tie point is located at and is departed from the pincers gill on pincers gill geometric center, the close position of binding clip, on the position near the pincers handle of the two pincers gills big cutting edge is set all, these two big cutting edges match to form big cutting edge cut part; All outwards convex with nock shape projection on two pincers handles, this two nocks shape projection is oppositely arranged, and the big clamping part of formation that matches.

Tie point with two calipers in the utility model departs from pincers gill geometric center, close binding clip, increases power arm when reducing resistance arm, thereby makes pliers reach the labour-saving effect.And on pliers, set up big cutting edge cut part and big clamping part, improved its practicality.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is two caliper open configuration structural representations.

Wherein Reference numeral is as follows:

First caliper 1, second caliper 2, binding clip 3, the pincers gill 4, pincers handle 5, big cutting edge cut part 6, big clamping part 7, little clamping part 31, little cutting edge cut part 32, bearing pin 41, breach 42, big cutting edge 43, nock shape projection 51.

The specific embodiment

As Fig. 1, shown in Figure 2, a kind of multi-functional laborsaving pliers of the utility model, comprise the shape symmetry, first caliper 1 that direction is opposite and second caliper 2, first caliper 1 and second caliper 2 comprise pincers handle 5 respectively, the pincers gill 4 and binding clip 3, binding clip 3 is provided with little clamping part 31 and little cutting edge cut part 32, first caliper 1 flexibly connects by bearing pin 41 at the pincers gill 4 places mutually with second caliper 2, tie point is located at and is departed from the pincers gill 4 geometric centers on the pincers gill 4, near on the position of binding clip 3, on the pincers gill 4, be provided with breach 42, when making the pliers folding, avoided the binding clip position of the pincers gill position of first caliper 1 and second caliper 2 inconsistent.On the position near pincers handle 5 of the two pincers gills 4 big cutting edge 43 is set all, these two big cutting edges 43 match to form big cutting edge cut part 6; On two pincers handles 5, all outwards convex with nock shape projection 51, two nock shape projections 51 and be oppositely arranged, and the big clamping part 7 of formation that matches.Tie point with first caliper 1 and second caliper 2 in the utility model departs from the pincers gill 4 geometric centers, also close binding clip 3, makes to increase power arm when reducing resistance arm, thereby makes pliers reach the labour-saving effect.And big cutting edge cut part 6 and big clamping part 7 on pliers, have been set up, big cutting edge cut part 6 can be used for shearing thicker object, big clamping part 7 can be used for the thicker object of clamping, thereby make the multi-functional laborsaving pliers of the utility model be applicable to the shearing and the clamping of the object of multiple thickness, improved its practicality.

Claims

1, a kind of multi-functional laborsaving pliers, it is characterized in that, comprise shape symmetry, first caliper and second caliper that direction is opposite, two calipers comprise pincers handle, the pincers gill and binding clip respectively, binding clip is provided with little clamping part and little cutting edge cut part, two calipers flexibly connect by bearing pin mutually at pincers gill place, tie point is located at and is departed from the pincers gill on pincers gill geometric center, the close position of binding clip, on the position near the pincers handle of the two pincers gills big cutting edge is set all, these two big cutting edges match to form big cutting edge cut part; All outwards convex with nock shape projection on two pincers handles, this two nocks shape projection is oppositely arranged, and the big clamping part of formation that matches.
