Bar 3；The threaded rod 3 is located in the wire clamp 1 and coordinated with the screw thread of wire clamp 1, and the dynamic folder 2 of the wire connects
It is connected on one end of the threaded rod 3；
In use, shorten the distance between the dynamic folder of wire and wire clamp by rotating clockwise or counterclockwise threaded rod
Or increase, clamp so as to realize or unclamp wire.
And in order to which remote operation threaded rod rotates, the present invention is also provided with transmission mechanism, and the transmission mechanism includes the
One articulated elements 41, the second articulated elements 42, first gear 43, second gear 44, connector 45, drive link 46 and insulated hollow bar
47, first articulated elements 41 is hinged and connected with second articulated elements 42, and the activity of connector 45 is located in described first
On articulated elements 41, the activity of drive link 46 is located on second articulated elements 42, and the insulated hollow bar 47 is set in institute
State outside drive link 46 and be fixedly connected with second articulated elements 42, the first gear 43 is fixed on leaning on for the connector 45
One end of nearly second articulated elements 42, the second gear 44 are fixed on close first articulated elements of the drive link 46
41 one end, the other end of the threaded rod 3 are detachably connected with the connector 45.
In use, rotating drive link, drive link drives second gear to rotate, and then second gear drives first gear to turn
Dynamic, then first gear band follower link rotates, and final connector drives threaded rod to rotate, and due to the first articulated elements and second
Articulated elements is hinged and connected, thus adjustable angle between the two, also allows for the adjustable angle of connector and drive link, is realized
Multi-angle changes, and meets actual installation angle demand.In addition, on the one hand the insulated hollow bar set plays protection staff's
Effect, the effect for fixing the second articulated elements is on the other hand provided, it is convenient to rotate drive link.
And in the present invention, threaded rod is detachably connected with connector, after installing ground wire, removable underdrive machine
Structure, insulated part will not be exposed in extraneous air for a long time, avoid influenceing the service life and insulating properties of insulated part.
In specific implementation, insulated hollow bar 47 is made of transparent material, convenient to observe operational circumstances；Wire clamp 1 is big
It is on bodyShape, for the dynamic folder 2 of wire in the opening of wire clamp 1, both clamping faces are arcwall face；The dynamic folder 2 of the wire
It is rotatably assorted with the threaded rod 3, the dynamic folder 2 of the wire is provided with chute, and the chute is axially parallel to the threaded rod 3
Axially, the middle part of the wire clamp 1 is caught in the chute and the slide coordinates.So dynamic folder 2 of wire is in moving process
In will not rotate, convenient clamping.

It is to be made up of multiple teeth 401 of a rotating disk 400 and the outer peripheral face for being arranged on the rotating disk 400, and the first gear 43
On one end of close second articulated elements 42 of the teeth 401 outwards exceed the first gear 43, second tooth
One end of close first articulated elements 41 of the teeth 401 on wheel 44 outwards exceeds the second gear 44.This tooth
The key point of wheel construction is that teeth outwards exceed, so, when needing connector with drive link coaxial transmission, the first tooth
Wheel and second gear can end face fitting be in coaxial state, both teeth can be intermeshed, and realize transmission, when need connector and
During the non-coaxial transmission of drive link, referring to Fig. 6, the axis of first gear and second gear forms an angle, now both teeth
Also can be intermeshed, realize transmission, so as to realize that Arbitrary Rotation is driven, realize the dynamic folder of wire and insulated hollow bar in 0~
180 ° of any angle changes.
When device leaves unused, direction of the drive link away from the first articulated elements is promoted, makes first gear and second gear
It is located remotely from each other, prevents both linkages, in use, first adjusting the angle between the first articulated elements and the second articulated elements, make both sets
Then drive link is promoted into coaxial state, makes first gear and second gear end by pipe towards close to the direction of the first articulated elements
Face is bonded, and the teeth intermeshing in first gear and second gear, now rotatable drive link carries out coaxial transmission, if needed
The angle of threaded rod and insulated hollow bar is adjusted, can now readjust the angle between the first articulated elements and the second articulated elements again
Degree, reaches the angle that needs meet, then rotates the rotation that drive link realizes threaded rod.
In specific implementation, the diameter of the rotating disk 400 is more than the internal diameter of described sleeve pipe 402, can prevent connector, transmission
Bar comes off.
In one embodiment, it is real by following structure with the connector 45 referring to Fig. 3, the other end of the threaded rod 3
It is now detachable to be connected：Inserting column 48 and sleeve 49 are respectively equipped with the other end and the connector 45 of the threaded rod 3, it is described to insert
Post 48 is provided with more than one limit stick 481, is provided with more than one stopper slot 491 on the sleeve 49, described during connection
Inserting column 48 is stretched into the sleeve 49, and the limit stick 481 is stretched into the stopper slot 491.This structure, connection are equal with dismounting
Very convenient, fast, practicality is high.
In one embodiment, it is embedded with magnet in the sleeve 49.This structure, inserting column and docking sleeve can be facilitated, carried
High joint efficiency, and attachment force can be increased, improve stability.
