Abstract
The utility model discloses a pair of cutting pliers, which comprises an upper jaw, a lower jaw, a handle, a shaft, an oil cavity, an oil pumping system and the like. The pair of cutting pliers is characterized in that the lower jaw is connected with the handle-shaped oil cavity; an oil pumping device is arranged in the oil cavity; and the upper handle is movably connected with the upper jaw. When the cutting pliers are used, the upper handle is connected with the upper jaw by that a pivot is moved by an 8-shaped shaft hole, the pressure of a jacking rod of the oil pumping device is released, and at the time, the cutting pliers can be used as common cutting pliers. If thicker iron wires or small-specification reinforcing steel bars need to be broken, the upper handle is backwards pulled and connected, the upper handle is separated from the upper jaw, the upper handle is pressed and pinched to pump oil, the rear end of the upper jaw is jacked up by a jacking device, and thereby strong breaking force is generated by the cutter point of the front part of the upper jaw. Thus, the purposes of strong breaking force and simple structure are realized, and the cutting pliers are flexible to use.
Description
Technical field
The utility model relates to a kind of machinery repair tool, specifically a kind of bolt clipper.
Background technology
At present, the cutting pliers that sell in market, common people's hand-power maximum can only clamp disconnected No. 8 galvanized wires, a little bit smaller slightly No. 8 galvanized wires of strength also clamp constantly, but in actual use, the reinforcing bar of the diameter of No. 5 galvanized wires or thicker galvanized wire or 6mm just is difficult to disrumpent feelings, must makes bigger broken string instrument disrumpent feelings, inconvenient operation lacks flexibility like this.
The utility model content
In order to overcome the little deficiency of existing cutting pliers broken string strength, the utility model provides a kind of cutting pliers, and these cutting pliers utilize hydraulic principle to realize more powerful broken string ability.
The utility model solves the technical measures that its technical problem takes, the head of cutting pliers is made lower jaw, connect with minor axis between the last lower jaw, front end is established the jaw and the edge of a knife, the rear end connects goes up lower handle, the rear portion downside of the upper jaw is tilted to, jaw shape axis hole is made in the rear end, and the rear portion upside of lower jaw is tilted to down and connects lower handle, and this handle upwards enlarges, in establish oil pocket, oil pump is set in oil pocket, and the high pressure flowline of oil pump passes to the lower jaw rear portion of oil pocket front portion and connects jacking apparatus (prior art), and being provided with near jacking apparatus drains the oil dials bolt, the push rod of jacking apparatus stretches out rear portion jaw upside, and push rod is aimed at upper jaw downside.The rear portion of described oil pocket is provided with oil filler, and oil filler seals with bolt.Oil pocket front end upside is set up post, column upper end bifurcated, and the top of two forks connects pivot.Upper handle is made arc, front end is made sphere, just in time stretch in the jaw shape axis hole of upper jaw rear end, and each other can be movable, the downside of upper handle front portion is opened the axis hole of the figure of eight, pack in the axis hole pivot of column upper end, handle can pivot, handle middle front part downside is opened chute at the rear of figure of eight axis hole, the piston rod of oil pump stretches out the upside of oil pocket, and its top is provided with in the chute that slide block is installed in the upper handle downside, and the cylindrical of piston rod is provided with spring between last lower handle, under the promotion of spring force, piston can be driven and upper handle makes progress together.During use, upper handle is pushed away forward, its spherical head stretches in the jaw shape axis hole of upper jaw rear end, pivot is positioned at the rear portion of 8 font axis holes, open the directly pressure release of oil that makes in the oil pump dialling bolt, push rod place lowest order is failure to actuate, press upper handle, prize the rear end of the upper jaw by pivot, the upper jaw rotates counterclockwise around axle the jaw closure can be bitten by the pincers thing, release handle opens at the effect lower jaw of spring force, unclamp by the pincers thing, if disrumpent feelings during than crude iron silk or reinforcing bar, upper handle is pulled back, make spherical head leave jaw shape axis hole, pivot is positioned at the front portion of 8 font axis holes, closes and dials bolt, and pressure is pinched upper handle and promoted the oil pump piston bar, make oil pump pump oil, hydraulic oil makes push rod to rising by pipeline, push the downside at upper jaw rear portion, make the edge of a knife closure of lower jaw head cut off iron wire, because the strength of its disrumpent feelings iron wire is from hydraulic system, therefore strength is bigger, thereby reaches the purpose that strengthens cutting pliers broken string strength.
The beneficial effects of the utility model are, and are easy to use, flexible operation, and broken string strength is big, simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a kind of structural representation of cutting pliers.
Among the figure, 1, head, 2, the upper jaw, 3, the edge of a knife, 4, minor axis, 5, lower jaw, 6, jaw shape axis hole, 7, ballhead, 8, pivot, 9, figure of eight axis hole, 10, top pincers handle, 11, spring, 12, piston rod, 13, dial bolt, 14, jacking apparatus, 15, oil pipe, 16, oil pump, 17, oil pocket, 18, oil filler.
The specific embodiment
In the drawings, the head 1 of cutting pliers is made the upper jaw 2 and lower jaw 5, connect with minor axis 4 between the last lower jaw, the oblique lower handle that connects down of the rear portion upside of lower jaw, this handle upwards enlarges, in establish oil pocket 17, establish oil pump 16 in oil pocket, the high-pressure oil pipe 15 of oil pump passes to the lower jaw rear portion of oil pocket front portion and connects jacking apparatus 14, is provided with near ejection device and dials bolt 13, at the rear portion of oil pocket oil filler 18 is set, oil pocket front end upside is set up post, and column upper end bifurcated connects pivot 8, and upper handle 10 is made arc, front end is made the downside of ballhead 7 handle front portions and is opened figure of eight axis hole 9, and pivot 8 is packed in this axis hole.The middle front part downside of handle is opened chute, and the piston rod 12 of oil pump stretches out the oil pocket upside, and its top is provided with slide block, is installed in the chute, and the piston rod cylindrical between last lower handle is provided with spring 11, and oil filler seals with bolt usually.
