It connects, holder glide direction is parallel to pinching screw axial direction, and pinching screw is in below holder, and head of screw is in below hook seat；
The Metallic hook be equipped with handle hole 1a for allowing short wire crosspiece to protrude into and for wait tear open set up it is standby
The connecting hole 1b of the connecting terminal connection of drainage thread.Metal hyphen rod segment diameter is less than or equal to operation bore dia.Stud and axis
It holds inner ring coaxially to fix, holder is fixed with bearing outer ring.
The package slot 12a to lower recess is equipped at the top of the holder, in handle hole axial direction, package slot penetrates through holder.Packet
Wrapping up in slot can preferably be bonded with high pressure bare conductor, improve clamping effect.
The insulation erects long rod segment perpendicular to metal hyphen rod segment, operates axially bored line and is parallel to connection axially bored line, hook seat is sliding
Dynamic direction is vertical.
When carrying out equipment and the overlap joint of high pressure bare conductor using the present invention, by the connecting terminal of equipment drainage thread, (equipment is drawn
After streamline is crimped with connecting terminal) it is fixed with connecting hole；By in the metal hyphen rod segment insertion operation hole for the rod piece that insulate, lift
Long rod segment is erected in insulation, Hook is suspended on high pressure bare conductor, high pressure bare conductor is between holder and Hook at this time.
Then by insulating sleeve turn pinching screw, band dynamic holder is moved up, thus with holder and Hook that high pressure is naked
Conductor clamping (since pinching screw is threadedly engaged with hook seat, stud and holder are rotatablely connected by bearing, holder and with hook seat
It is slidably connected, so turn pinching screw can be moved up and down with dynamic holder).Finally extract insulation rod piece (metal hyphen bar
Section), just complete band electrical bonding.If wanting electrification disassembly, by insulating sleeve turn pinching screw, band dynamic holder is moved down,
High pressure bare conductor is unclamped, is then protruded into insulation rod piece (metal hyphen rod segment) in handle hole, then lift insulation and erect long rod segment, take
Lower Metallic hook.
Embodiment 2: the basic structure and embodiment of the present embodiment are same to apply example 1, the difference is that, such as Fig. 3 to Fig. 6
Shown in, the auxiliary through slot 1c that the Metallic hook is equipped with cleaning cylinder body 4 and is in below handle hole, auxiliary through slot and handle hole connect
It is logical, starting air bag 51 and the starting plate 52 with starting balloon contacts are equipped in auxiliary through slot, starting plate is in above starting air bag, opens
Movable plate is slidably connected with Metallic hook, and starting plate glide direction is vertical, is equipped with to be slidingly sealed with cleaning cylinder body in cleaning cylinder body and match
The cleaning piston 41 of conjunction, cleaning piston glide direction is horizontal, cleaning piston will clear up cylinder interior be separated into the first cavity 4a and
Second cavity 4b, the second cavity is interior to be equipped with reset spring 42, reset spring one end connection cleaning piston, reset spring other end company
Connect cleaning cylinder body；
First cavity is connected to by main tracheae with starting air bag, and cleaning cylinder body is equipped with several auxiliary tracheaes 61, overdose space
Interior to be equipped with injection nozzle carrier 6, injection nozzle carrier is equipped with several air nozzles 62, has overdose space, folder between holder bottom surface and hook seat top surface
It is screw modulation section that tight screw, which is in the part in overdose space, and air nozzle is towards screw modulation section, air nozzle and auxiliary tracheae one
One is corresponding, and air nozzle is connected to the second cavity by corresponding auxiliary tracheae.
The reset spring axis is parallel to cleaning piston glide direction, and Metallic hook is equipped with down auxiliary slot, clears up cylinder body
Under being in auxiliary slot, all auxiliary tracheaes both pass through down the notch of auxiliary slot.
The cleaning piston is equipped with horizontal piston rod 43, and horizontal piston rod is equipped with tranverse connecting rod 431, and tranverse connecting rod both ends are equipped with
Brush board 432 forms between two brush boards at tranverse connecting rod both ends and cleans space with water, and brush board is equipped with multiple for cleaning screw modulation section with water
Elastic wire bristle, each air nozzle and all elastic steel wire bristle be in and clean with water in space, and brush board is in overdose space,
Horizontal piston rod one end is protruded into the second cavity, and horizontal piston rod length direction is parallel to any brush board, in horizontal piston rod length direction
On, the first cavity, the second cavity clean space with water and screw modulation section is sequentially arranged.
The tranverse connecting rod is horizontally disposed, and tranverse connecting rod length direction is perpendicular to horizontal piston rod length direction, tranverse connecting rod is in clearly
It brushes in space.
After having overlapped equipment, the present invention is in a fixed state.When needing to charge disassembly, as previously mentioned, needing
It to be moved down by insulating sleeve turn pinching screw come band dynamic holder, i.e. screw modulation section needs move down.But, due to the present invention
Situations such as being in outdoor environment, entrance (biggish) impurity can be inevitably encountered at screw modulation section, so as to cause turn
When pinching screw, pinching screw cannot smoothly descend turn mobile, and the present invention be both electrification and aloft, worker is very
It is difficult directly to being cleared up at screw modulation section.
It in the present embodiment,, can be first by metal hyphen bar when needing to charge disassembly shown in by taking visual angle in Fig. 3 to 6 as an example
Section protrudes into handle hole, and drop-down insulation erects long rod segment and will drive metal hyphen rod segment when the drop-down of long rod segment is erected in insulation and move down, from
And pushing starting plate, starting plate flatten starting air bag, a part of gas enters the first cavity through main tracheae in starting air bag, cleaning
Piston moves right (reset spring compression), to gas in the second cavity be extruded from each air nozzle, to screw modulation section
Place carries out blowing-out, to remove the impurity at screw modulation section.
At the same time, cleaning piston drives brush board to move to right by horizontal piston rod, tranverse connecting rod, thus the elastic wire on brush board
Bristle directly cleans screw modulation section with water, acts in conjunction with above-mentioned blowing-out, can further effectively remove impurity, ensures screw tune
Becoming section can smoothly move down.And insulate and erect after long rod segment is pulled down, then discharged, under action of reset spring, each structure can be with
It resets.The pulling operation that long rod segment is erected in insulation can carry out repeatedly, to carry out multiple blowing-out and clean with water.
Then, it can be moved down by insulating sleeve turn pinching screw come band dynamic holder, to unclamp high pressure bare conductor, then again
Insulation is lifted to erect long rod segment, remove Metallic hook.
