The pulling force opened between insulator and conducting wire is transferred on stringing frame, convenient for being replaced to insulator.Due to being adjusted using lead screw,
So will not skid after being tensed, it is more effortless more reliable than traditional cord holder without relocking, it is safe.
Further, the gripper is equipped with U-shaped ring, and the preceding snap-gauge is equipped with card column, and the gripper is by U-shaped ring with before
The card column of snap-gauge connects.Using the cooperation of U-shaped ring and card column, replacement dismounting can be carried out to gripper, it is easy to carry and use, it carries
For the working efficiency of operating personnel.
Further, the gripper is equipped with safety plug.Increase safety plug further to the double fastener part ambulatory splint of gripper
It is locked, so that conducting wire is consolidated when carrying out clamping not easily to fall off.
Further, the rear snap-gauge, which is equipped with, extends ring, and the extension ring is fixedly connected by bolt with rear snap-gauge.Extend ring
It is connected and fixed convenient for the device and the cross-arm on Electric wire support, to prevent abjection insurance occurs.
Further, the rear snap-gauge is equipped with arc section, and the extension ring is arranged on the top of arc section.The circular arc of snap-gauge afterwards
The adhered shape of section and insulator, it is more firm when carrying out clamping, it is not easy to skid, extension ring is arranged is conducive to pulling force on top
It transmits, the power of stringing frame is shared to the cross-arm being connect with rear snap-gauge in the form of triangle.
The utility model has the beneficial effects that；
One, gripper is improved, easier installation gripper, safety, insurance are made；
Two, the stringing frame constituted using double lead, it is more effortless more reliable than traditional cord holder, it will not skid, it is safe；
Three, traditional gripper and the merging of cord holder function are designed as a set of new fixture, reduce connecting component, makes
Work tool uses more convenient, safety.
