With the connection structure that plane is in clamping connection on phase cross-arm in steel tower；
Wire tensioning screw is provided in the middle part of the snap-gauge；
The connection structure of snap-gauge both ends setting is and planar dimension matches on phase cross-arm in steel tower groove；For snap-gauge
Clamping fixation is carried out with plane on middle phase cross-arm；
The Wire tensioning screw bottom is connected with insulation pull-rod, and the bottom end for the pull-rod that insulate is linked up with equipped with yoke plate；
The yoke plate hook is connected on " V " type insulator chain yoke plate of pylon；
The yoke plate hook is that LF type yoke plate is linked up with；
The snap-gauge material be LC4 aluminium alloy, possess it is firm, be not easy the advantages of corroding, wearing；
The beneficial effects of the utility model are: the utility model, which is mounted on plane on middle phase cross-arm, can increase screw rod in
The distance of phase conductor improves operational security to increase the security combination gap of operating personnel；And the fixture is mounted on middle phase
Plane on cross-arm, the tower operator may stand in middle phase cross-arm lower plane, and upright body tightens screw rod, to reduce operation people
Member's labor intensity；The utility model provides advantage for the safe livewire work of realization.The installation and removal of this product are compared
It is convenient, to reduce the work load of installation personnel；This product mounting means in operation is simple and convenient, reduces the use of device
Difficulty, while reducing the workload and work difficulty of operator, to improve the working efficiency of operator；
The service life of device also can be improved in simple and durable apparatus structure, reduces the use cost of user.
