Abstract

The utility model discloses a pliers which can implement not only the traditional pliers function but also the wire stripping function and comprises one pair of pliers head, one pair of pliers stalk and a connecting pin. A fixed blade set is fixed on one of the pliers stalk. And the other pliers stalk is provided with a movable blade through a positioning pin. One end of the movable blade is kinetically arranged on the connecting pin through a positioning pin. A circular oriented groove is also arranged on the movable blade. Through the oriented groove, the size of the wire stripping blade edge can be adjusted. The spike teeth are arranged on the bottom edge of the movable blade. The paw arranged on the clamp stalk used for the restrictions of the counter clockwise rotation of the movable blades plays a role of the locking of the wire stripping blade edge. After the wire stripping structure above is added on the traditional pliers, on one hand the specialized wire stripping tools is not necessary to be carried any more during the outing works, on the other hand, the trouble of frequent tool replacements during the operation can be avoided.

Description

Pliers

Technical field

The utility model relates to a kind of pliers, refers more particularly to a kind of pliers with wire stripping mechanism.

Background technology

Pliers is as a kind of traditional hand-operated tools, all obtained utilization widely in all trades and professions, it mainly comprises cutting pliers, nipper plier, tiltedly chews pincers, wire stripper etc., their structure is quite similar, comprise: a pair of binding clip, a pair of pincers handle and be connected bearing pin, common left binding clip fuses with right pincers handle and forms a caliper, and right binding clip fuses with left side pincers handle and forms another caliper, and these two calipers intersect stacked and are hinged by connecting bearing pin.During use, a pair of pincers handle of operator grasps, by be applied to the power of pincers on the handle realize to object clamping, reverse, function such as shearing.When the operator uses this traditional pliers to carry out field operation,,, utilize the jaw wire stripping relatively harder but also injure heart yearn easily because this tradition pliers do not have special wire stripping mechanism in case need wire stripping; When meeting this situation certainly, can use special-purpose stripping tool, but do like this, increase the daily burden of carrying on the one hand, always varying on the other hand, it is cumbersome to operate.

Summary of the invention

Technical problem to be solved in the utility model provides the pliers that a kind of function that can realize traditional pliers can realize the wire stripping function again.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: pliers, comprise a pair of binding clip, a pair of pincers handle be connected bearing pin, on a pincers handle, be set with a ledger-plate, ledger-plate is provided with the wire stripping cutting edge half, on another pincers handle, be provided with a movable blades by alignment pin, movable blades can rotate around alignment pin, also be provided with the wire stripping cutting edge on the movable blades half, half wire stripping cutting edge on the ledger-plate can close up into a complete wire stripping cutting edge with half wire stripping cutting edge on the movable blades, and also being provided with between movable blades and pincers handle can be with the buckling and locking device of movable blades kayser location.

The a kind of of above-mentioned buckling and locking device specifically is set to: the bottom margin place at movable blades is provided with ratchet, and the pincers handle is provided with the ratchet that matches with ratchet; Ratchet is movably arranged on the pincers handle by screw, also is provided with torsion spring on screw, and the end of torsion spring rides against respectively on ratchet and the pincers handle.

A kind of concrete set-up mode of above-mentioned movable blades is: an end of movable blades is movably arranged on by alignment pin and connects on the bearing pin, also is provided with a circular arc gathering sill on movable blades, and the pincers handle is provided with the screw that matches with this circular arc gathering sill; And the setting of staggering mutually of movable blades and ledger-plate that is: makes the lower surface of movable blades be positioned at the top of ledger-plate upper surface.

The outer side edges of above-mentioned movable blades is provided with plectrum.

The beneficial effects of the utility model are: after having installed above-mentioned wire stripping mechanism on traditional pliers additional, needn't carry special stripping tool again when going out operation on the one hand, avoid the trouble of frequent replacing instrument in the operating process on the other hand.

Fig. 2 is an A-A cutaway view among Fig. 1;

Fig. 3 is the partial enlarged drawing of B part among Fig. 1.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing, but the utility model should not only limit to this embodiment.

As shown in Figure 1, the novel described pliers of this full mold comprises: a pair of binding

clip

11,12, a pair of

pincers handle

21,22 and be connected bearing pin 3; Be set with a ledger-plate 4 on a pincers handle 21, ledger-plate 4 is provided with wire stripping cutting edge 41 half; One end of movable blades 5 is movably arranged on the connection bearing pin 3, also can rotates around alignment pin 7 by alignment pin 7, and the bottom of movable blades 5 is provided with a circular arc gathering sill 52, pincers handle 22 is provided with the screw 53 that matches with this gathering sill 52; Can close up into a complete wire stripping cutting edge with half wire stripping cutting edge 41 on the ledger-plate 4 also being provided with half wire stripping cutting edge 51 and this half wire stripping cutting edge 51 on the movable blades 5; Movable blades 5 is the setting of staggering mutually with ledger-plate 4, that is: the lower surface of movable blades 5 is positioned at the top of the upper surface of ledger-plate 4---as shown in Figure 2; Bottom margin place at movable blades 5 is provided with ratchet 54, pincers handle 22 is provided with the ratchet 6 that matches with ratchet 54, ratchet 6 is movably arranged on the pincers handle 22 by screw 9, also be provided with torsion spring 8 on screw 9, an end of torsion spring 8 can stretch in the aperture of ratchet 6, the other end can be arranged in the cavity of pincers handle 22---as shown in Figure 3.For easy to use, also can on two

pincers handles

21,22, install additional and grip comfortable handle, the outside of movable blades 5 can be provided with a plectrum 55.During use, pliers described in the utility model realize clamping, reverse, during traditional function such as shearing, in full accord with the using method of traditional pliers, do not repeat them here; When using pliers described in the utility model to carry out wire stripping, regulate wire stripping cutting edge size two kinds of situations arranged: first kind of situation---when ledger-plate 4 and movable blades 5 close up the external diameter of the internal diameter size of wire stripping cutting edge and heart yearn do not match, in the time of need turning the wire stripping cutting edge down, relatively do not move to left owing to ratchet 6 can not hinder movable blades 5 this moment, therefore only need to push the plectrum 55 that is arranged on the movable blades 5, allow movable blades 5 turn clockwise left and just can turn the wire stripping cutting edge down to correct position along ratchet 6; Second kind of situation---when ledger-plate 4 and movable blades 5 close up the external diameter of internal diameter size and the heart yearn of wire stripping cutting edge do not match, during the big wire stripping cutting edge of needs accent, this moment is because ratchet 6 has hindered moving to right relatively of movable blades 5, therefore, apply a thrust that makes progress, make ratchet 6 unload lock at first will for ratchet 6 terminal bottoms, that is: ratchet 6 leaves the ratchet 54 that is arranged on the movable blades 5, and keeps this state; Then, according to the thickness of heart yearn, outwards pushing is arranged on plectrum 55 on the movable blades 5, is in the position that an external diameter with heart yearn is complementary up to movable blades 5, at this moment unclamps ratchet 6 and allow itself and ratchet 54 mesh to get final product.
