The middle part that T connects transverse link has outward extending brace; This brace clamping connection is fixed on the straight line pole cross-arm and T connects between the longitudinal rod; Make T connect transverse link and connect with T that longitudinal rod is T-shaped to be connected, straight line pole cross-arm, T connect longitudinal rod and brace passes through bolt
Have two on each quarter bend stud and cooperate right angle pad and two nuts; Each cooperates a right-angle plane of right angle pad to be enclosed within on the quarter bend stud; The two ends of each quarter bend stud are combined with a nut respectively, and two quarter bend studs connect longitudinal rod with T and are fixedly connected with the straight line pole cross-arm.
Said T connects two locating slots of longitudinal rod upper edge horizontally set, and these two locating slots are used to realize spacing to two quarter bend studs.
Said two locating slots connect on the longitudinal rod at T and are symmetrical distribution along horizontal center line.
It also comprises boss, and this boss is arranged on the lateral middle that T connects longitudinal rod.
Advantage of the present invention is: the present invention is through installing one group of linkage additional on original straight line pole cross-arm; Original straight line pole cross-arm can effectively be connected with last fourth cross-arm easily; Make the livewire work process on the transmission line of electricity safer, and job practices is simple, convenient.
Safety of the present invention and economy are taken into account, and have both ensured work progress personnel's safety, make the process of charged installation become simply high efficiency again.
