Therefore, the present invention is adopted the following technical scheme that：A kind of conical friction formula fixing-line device, including wire cramping body, institute
The wire clamping stated is external to be cased with an outer frame body, one end of each one connecting plate of connection in the both sides of the outer frame body, two connecting plates it is another
One end is fixedly connected using fastening assembly；
Described wire cramping body is formed by two circular cone docking, and the cross section of the circular cone is in semi-circular shape, and described is outer
Framework is used to lock two circular cones.
The present invention grips wire by the assembling of above-mentioned each parts, and under tension, circular cone can be from circumference
Face diameter is effectively uniformly transferred to steel core frictional force to clamping skin aluminum steel.
Further, two described circular cones are achieved a butt joint using the structure that groove coordinates with projection.Using concavo-convex knot
Structure is mutually twisted, it is to avoid relative movement is produced between two circular cones.
Further, each circular cone is equipped with a groove and a projection, sets up the front and back ends in circular cone separately, can be effective
Avoid producing relative movement between two circular cones.
Further, two described circular cones are embedded with magnet, using magnet that two circular cones are attracting integral, square
Just its assembling with outer frame body.
Further, described outer frame body is formed by two half shell docking, and one end is connected using fixed hinge, the other end
Using activity pin connection.The folding of outer frame body is realized using the rotation of fixed hinge, facilitates the dress of outer frame body and wire cramping body
Match somebody with somebody.
Further, the outside of the outer frame body is provided with boss, and the end of connecting plate is provided with the company used cooperatively with boss
Connect hole.By the cooperation of boss and connecting hole, one end of connecting plate is set to be positioned on outer frame body.
Further, described fastening assembly is by a nut used through the screw of two connecting plates and one and screw fit
Composition.
Further, the madial wall of the outer frame body is in truncated cone-shaped.
Further, the inwall of described two circular cones is provided with the helicla flute for increasing frictional force.Helicla flute can be with
Substantially increase the frictional force between the inwall and conductive line surfaces of circular cone.
The invention has the advantages that：The present invention is applied to all kinds wire, is particularly well-suited to gap-type conductor,
Effectively tension force can be applied to gripping wire, simple structure is easy to assembly.
