Description

Multiduty pliers

The utility model is electrician, the requisite common tool of repair of machine worker, also be do in the daily life some odd jobs (nail pulling, cut off galvanized wire, the binding galvanized wire) utility.

Though former combination pliers has the function of cutting off electric wire or galvanized wire, binding galvanized wire, twisting round nut (bicycle valve nut), does not have the wire stripping function, set bolt cap and stubborn hexagonal primary nut function do not have the nail pulling function yet.There is not the wire stripping function, the electrician is when the wiring operation, must with combination pliers electric wire be cut off earlier, change the line skin that wire stripper peel off the end of a thread then, changing combination pliers again tightens the end of a thread, so whenever, connect a end of a thread and all will repeat the replacing instrument, it is neither coherent also inconvenient to operate, and carries to the electrician and to have increased weight.

The mechanic also is combination pliers commonly used when repairing, the one, and with combination pliers set bolt cap, the 2nd, twist the hexagonal primary nut.Ovalisation is done at former combination pliers nutting position, in the slip teeth of setting up defences, stubborn round nut still is relatively good usefulness, but it is just not too practical that the mechanician is twisted the hexagonal primary nut.Because six side's contact-making surfaces of its shape and anti-slop serrations and hexagonal primary nut seldom, just toe joint touches, and twists so get with very big strength nut to be fixed again earlier when nutting, and strength is all done and is used on the binding nut, but also usually circle is gnawed at the angle of hexagonal primary nut, cause the dismounting difficulty.

The carpenter usually will extract reprocessing with the nail on the old timber when doing woodwork.Former combination pliers does not have the nail pulling function, and carpenter's often first handy chisel when nail pulling is dug out the timber below the head of a nail around nail, and then pulls out with combination pliers, because it does not have leading edge, so pull up very hard.Also have and dailyly do that some odd jobs also need be with combination pliers, limited because of former combination pliers function, also just restricted its work efficiency.

The purpose of this utility model just provides a kind of multiduty pliers that multinomial function is arranged.The effect of the more effective performance combination pliers of its energy makes the gram silk function of its existing combination pliers, and the wire stripping function of wire stripper is arranged again, and set bolt cap and stubborn hexagonal primary nut function also have the nail pulling function.Just can do multi-mode operation with a pair of tongs, make work more convenient, faster.

The purpose of this utility model is achieved in that on the basis of former combination pliers the cutting edge position of former combination pliers being processed into two uses part, a part by the cutting edge root toward the last period approximately (5-7) mm still as the gram silk position of cutting off electric wire or galvanized wire, because this position is to cut off not only laborsaving but also active component of electric wire or galvanized wire.Another part is formed the wire stripping position by the little cutting edge that (5-7) mm is processed into different-diameter more forward.The little cutting edge that the different-diameter at this wire stripping position has been arranged just can be cut off the electric wire line skin of different-diameter, gets final product wire stripping.

With the processing growth hexagon space, opposite side space at gram silk position and wire stripping position, fix the nuts of M8-M12 with this long hexagon space.The slip teeth of setting up defences in the ellipse hole with combination pliers changes to be processed into and establishes fine and closely woven non-skid thread in the diamond hole, twists the hexagonal primary nut of M4-M6 with this diamond hole.The relative obtuse angle on diamond hole both sides all is processed into 120 °, and fine and closely woven non-skid thread is processed in the inboard.The angle of hexagonal primary nut also is that 120 ° of angles with diamond hole match like this, and is not only laborsaving but also circle can not gnawed in the angle of hexagonal primary nut when twisting primary nut.Because of the inboard is provided with fine and closely woven non-skid thread, so still can twist round nut.And the jaw position also is processed into two uses parts, a part is still made the plane, and annular knurl in the plane, makes binding galvanized wire or tightens electric wire usefulness with this annular knurl plane.Another part is beaten groove in small holes of the side of jaw processing and cambered surface and is joined and constitute the little leading edge of a folding, has had so little leading edge just can nail pulling.

The concrete structure of utility model is provided by following embodiment and accompanying drawing.Fig. 1 is the front view and the cutaway view of the multiduty pliers function that the utility model proposes of root a tree name.Fig. 2 is the schematic diagram of the multiduty pliers set bolt cap function that the utility model proposes of root a tree name.

Fig. 3 is the schematic diagram of twisting hexagonal primary nut function according to the multiduty pliers that the utility model proposes.

Describe details and effect in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3 according to the multiduty pliers function that the utility model proposes.What wherein every parenthetic sequence number was not indicated Fig. 2, Fig. 3 all is the sequence number of Fig. 1.

1. the gram silk position (1) of this multiduty pliers, it is that cutting edge position separated into two parts with former combination pliers uses, gram silk position (1) is that the sub-fraction of former combination pliers cutting edge is not changed, and grows (5-7) mm approximately.(length can be decided according to jaw length).Cut off electric wire or galvanized wire not only effectively but also laborsaving with this short section cutting edge, again from (5-7) mm forward by the circular little cutting edge (diameter of little cutting edge is fixed by the metal-cored diameter of electric wire) of pore diameter size order addition different-diameter, form wire stripping position (2).It is individual that the cutting edge at wire stripping position (2) generally can be made (4-6), decides according to the length of jaw.When shelling electric wire the end of a thread of different-diameter, the hand of holding pincers opens cutting edge electric wire the end of a thread of different-diameter is put into wire stripping position (2) and the corresponding little cutting edge of electric wire wire diameter, the pliers of holding with a firm grip is then promptly cut off the closed electric wire line skin like this of cutting edge.Because identical with the little cutting edge diameter of selecting for use, so when the cutting edge closure, just the line skin of electric wire can only be cut off and can not hinder metal wire by the electric wire metal wire cut.After the line skin is cut off, holding the hand of pincers exerts oneself a little with the reciprocal direction of palmistry of holding line, the end of a thread line skin is promptly peeled off, this be because electric wire line skin no matter be plastics or rubber retractility all arranged, the metal wire surface is all very smooth again, line skin within 3 centimeters is easy to be stretched out, firmly just can finish the wire stripping operation a little thus.

2. this multiduty pliers set bolt cap function is the processing growth hexagon space (3), opposite side space with gram silk position (1) and wire stripping position (2), fixes the nuts of M8-M12 with these long six side spaces (3).(1) in the accompanying drawing 2 is fixing M8 nuts, and multiduty pliers is in closure state.Because the nuts relative edge's of M8 width S is 12mm, the diameter D of relative angle is 16.2mm, and relative edge's width S of M12 nuts is 17mm, and the relative angle diameter is 19.6mm.So the width in this long hexagon space (3) is processed into 12mm by two relative edges' of M8 nuts width S.The longest relative angle length in this long hexagon space (3) is processed into 19.6mm by two relative angle diameter D of M12 nuts.The width that 12mm has been arranged is put into this long hexagon space (3) with the M8 nuts, and two limits are just in time blocked simultaneously.The diameter that the 19.6mm relative angle has been arranged, multiduty pliers opens an angle, the M12 nuts is put into this long hexagon space (3), 1/2 limit of nuts just in time matches with one side that this grows hexagon space (3), as long as another side blocks an angle and just nuts can be fixed, its duty is provided by (3) in the accompanying drawing 2.The M10 nuts is the intermediate sizes of M8 and M12 nuts, and promptly M8 and M12 nuts can both be stuck, and that M10 nuts just can be stuck.Its duty is provided by (2) in the accompanying drawing 2.The mechanician is with this long hexagon space (3) set bolt cap, as long as just can be with nut screwing clamping with the equidirectional rotation of nut with nuts.As difference because of pliers specification size.Sky can be cut in 19.6mm angle in front.

3. the diamond hole of this multiduty pliers (4) is that the ellipse hole with former combination pliers is processed into diamond hole (4).The obtuse angle, both sides of diamond hole (4) all is processed into 120 °.Be processed into fine and closely woven non-skid thread (5) in the inboard of diamond hole (4), the direction of non-skid thread (5) is parallel with the through hole direction of diamond hole (4).Width between the degree of depth of non-skid thread (5) and mutual line all is 0.6mm.When mechanician or electrician twist the primary nut of M4, M5, M6,, the angle of primary nut matches with two relative obtuse angles of diamond hole (4) because of all being 120 °.The distance at the relative obtuse angle, both sides of diamond hole (4) is 8.1mm, and this is that two relative angle diameters according to the M4 primary nut are 8.1mm and fixed.120 ° of the angles that two relative obtuse angles have been arranged have had the relative distance 8.1mm at two relative obtuse angles again, and the distance of such two relative acute angles is 13.9mm.And the distance of two relative angles of M6 primary nut is 11.5mm, so no matter be that the primary nut of M4, M5, M6 can both be stuck and tightens, its duty is provided by accompanying drawing 3.(1) in the accompanying drawing 3 is the duty of twisting little six square nuts of M4, and (2) in the accompanying drawing 3 are the duties of twisting M5 six side's primary nuts, and (3) in the accompanying drawing 3 are the duties when twisting the M6 primary nut.Again because of diamond hole (4) inboard is provided with fine and closely woven non-skid thread (5), so still can twist round nut.

4. the jaw position of this multiduty pliers also is processed into two and is used parts, a part still to make plane and annular knurl (6) in the plane, with this plane annular knurl (6) still as the binding galvanized wire or tighten electric wire usefulness.And the front of the plane annular knurl (6) of jaw and side all are operable.Another part is in the another side of a jaw processing small holes (7), small holes (7) but diameter addition 6mm, the degree of depth also is processed into 6mm.Transverse plane before the jaw of former combination pliers is processed into cambered surface (8), and small holes (7) and cambered surface (8) are beaten groove (9) and are joined, and just constitute a little leading edge (10).So little leading edge (10) has been arranged, when the carpenter works as must nail pulling just can be with this little leading edge (10) nail pulling.This little leading edge (10) and long hexagon space (3) are on same side.
