Description
Technical field
A kind of electric construction tool is the utility model is related to, more particularly to a kind of cable grip.
Background technology
In electric system overhead high voltage line laying construction or tour, the tension of high-tension line is one very important
Work, directly influences the use of whole power circuit, if power line passes by pine, sag is excessive, easily swings, mutually
Short circuit occurs for collision；If power circuit tension, broken string easily occurs or breaks line bar.Cord holder is indoor for tightening
The conducting wire specific purpose tool of porcelain vase circuit and outdoor aerial circuit, is made of clamp binding clip, locating groove, tightening gear and handle etc..
In use, drag hook must construct stringing stent or cross-arm, clamp binding clip clamps the end for needing stringing lead, repeatedly rotational handle,
Conducting wire is set gradually to tighten.
Publication No. CN105914657A Chinese patents disclose a kind of portable double plate circulation cord holder and its application
Line tightening method, including ratchet thread tensioning mechanism and be separately positioned on ratchet thread tensioning mechanism both ends activity pull strings mechanism and fixation lead
Line end, the ratchet thread tensioning mechanism include being mounted side by side on two twisted wire boxes on bearing bracket stand, the twisted wire box respectively with two groups
Coaxial ratchet is connected and is together rotatablely installed in the wire box shaft on bearing bracket stand, and two groups of ratchets are respectively equipped with crevis and biography
Pawl, the crevis are installed on bearing bracket stand, and the driving click is installed on the switching handle being connected with wire box shaft
On, promote ratchet one-way to rotate by pulling switching handle；Two groups of driving clicks are connected with ratchet clutch adjuster respectively；It is described
Activity pulls strings mechanism as two groups, is connected respectively by draught line with two twisted wire boxes, and fixation end of pulling strings is connected with bearing bracket stand.
Above-mentioned this portable double plate circulation cord holder, when stringing, need to use manual operation, but as conducting wire is thicker, circuit
The increase of span and line footpath, since the length of switching handle is constant, that is, arm of force when rotating is constant, the power of labor costs during stringing
Gas can gradually increase, so that time-consuming and laborious.
Utility model content
The purpose of this utility model is to provide a kind of cable grip, and according to lever principle, tightening force can be increased by having
The arm of force so that required power reduces when rotating switching handle, reach time saving and energy saving effect.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of cable grip, including ratchet thread tensioning mechanism, be located at ratchet thread tensioning mechanism both ends activity pull strings mechanism and
Fixed end of pulling strings, switching handle is connected with the ratchet thread tensioning mechanism；
The switching handle inner is hollow, and prolonging handle is connected with by telescoping mechanism in the switching handle.
By using above-mentioned technical proposal, operation prolonging handle tightens cable, adds arm of force during rotation, according to
Lever principle, so that the power acted on switching handle reduces, reaches time saving and energy saving effect.
Further, the telescoping mechanism includes setting along the radial direction of switching handle and runs through the location hole one of switching handle
With location hole two, the telescoping mechanism further includes the location hole three being located on prolonging handle, is equipped with and positioning in the location hole three
The latch that hole one and location hole two coordinate；
When location hole one is overlapped with location hole three, the prolonging handle is partially submerged into switching handle；
When location hole two is overlapped with location hole three, the prolonging handle stretches out switching handle.
By using above-mentioned technical proposal, when extension rod is not required to stretch out switching handle, location hole one is moved to positioning
At hole three, latch is inserted into location hole one and location hole three；When extension rod needs to stretch out switching handle, location hole one is moved
Move to location hole two, latch is inserted into location hole one and location hole two to the position for fixing prolonging handle.By prolonging handle to electricity
Cable is tightened, and adds arm of force during rotation, so that the power acted on switching handle reduces, reaches time saving and energy saving effect
Fruit.
Further, the location hole one is set with location hole two each along switching handle same length direction；
The prolonging handle is equipped with guide pad, and the guide groove coordinated with guide pad is equipped with the switching handle；
