Abstract
The utility model belongs to a hand cutting tool stripping the cable insulation on some end for electrician purpose. The elementary structure is an adjustable bearing rod of radial distribution of annular frame and a tool rod with the function of realizing circumferential direction and longitudinal slitting the cable insulation layer on the cable end. The utility model has the advantages of simple and light structure, convenient operation and high reliability, which can be used for the operation of installation and repair of cable in the field of telecommunication, electric power, architecture, chemical industry, etc.
Description
The utility model belongs to a kind of electrician's specialized hand cutter that divests cable insulation from its end.
Each discloses a kind of hand-operated tools that divests cable insulation in CN86205924U, CN87200539 U and CN86208004U.Its common drawback is that structure is loaded down with trivial details, troublesome poeration and carry inconvenience.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and the electrician's specialized hand cutter that divests cable insulation from its end that a kind of ring-type three fulcrums are provided.
The purpose of this utility model can reach by following structure:
A kind of electrician's specialized hand cutter that divests cable insulation from its end is made up of by major part ring-type framework, radially-arranged two cramp bars of framework and one or two knife bar and knife bar feeding cover.Be connected by threaded engagement between the external diameter of cramp bar and feeding cover and the framework.The shape of knife bar is that front end is that blade, middle part are that anti-rotation cylinder, the rear portion of rib body or splined shaft is the revolving body of garden post or step axle.The internal diameter matched in clearance of the rear portion external diameter of knife bar and feeding cover, and its middle part forms axial sliding fit with framework.In order to realize that knife bar rotates and the location, between knife bar and framework, be provided with a moving runner.The middle part anti-rotation cylinder of knife bar does not directly cooperate with framework, but earlier with the interstitial hole axial sliding fit of moving runner, the turned position of the flexible positioning and locking accessory restriction moving runner formed of rigidity positioning and locking screw of packing into by the race restriction moving runner axial location offered at the end face of framework with from the external diameter of framework or ball spring screw reaches the purpose that the control knife bar rotates again.In order to reduce friction resistance and be convenient to operation, be equiped with the ball cover and the ball in the ball cover of its threaded engagement and be provided with handle in its back-end at the supported end of cramp bar.For knife bar is promoted smoothly, at the withdrawing shaft shoulder of major part screw of the rear end of knife bar assembling or screw back-up ring composition.
The utility model has the rapidly convenient and laborsaving advantage such as reliable of light and handy and compact and reasonable simple in structure and operation compared to existing technology.
Accompanying drawing is the utility model specific embodiment sectional arrangement drawing.
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment:
The axis of garden ring-type framework 1 radially-arranged cramp bar 2,3 and knife bar 4 meets at the garden heart of framework 1.Angle is 90 ° between cramp bar 2,3 axis, and the axis of knife bar 4 overlaps with its angle bisector.The front end of knife bar 4 is that curved blade, middle part are that four-prism, rear portion are that diameter is less than the garden post of prismatic external garden, middle part column diameter, the shaft shoulder 9 that the rear end is made up of back-up ring and screw.The external diameter of cramp bar 2,3 and feeding cover 5 cooperates with framework 1 by screw thread.The internal diameter matched in clearance of knife bar 4 rear portion external diameters and feeding cover 5, its middle part then with the center square hole axial sliding fit of moving runner 6.Flexible positioning and locking accessory 8 restrictions that the axial location of moving runner 6 then is made up of ball, spring and screw end face groove 7 its turned positions of restriction of framework 1.The supported end of cramp bar 2,3 is equipped with ball cover 10,11 and ball 12,13 by screw thread.The knob of being convenient to operate respectively is processed in the rear end of cramp bar 2,3 and feeding cover 5.
