The technical scheme in the invention for solving the above technical problem is: this lightning rod comprises shank and wire clamp, shank is served as reasons and is gone up the crosspointer structure of pin and side pin composition, wire clamp is movably connected to form by upper and lower wire clamp piece and rotational pin, its design feature is also to be provided with pretension frame, push rod, pad, spring and alignment pin, shank and pretension frame are structure as a whole, the fixture block that rolls off the production line is positioned at a side of pretension frame and is structure as a whole with the pretension frame, and the fixture block of reaching the standard grade has an outward extending latch segment; Alignment pin and push rod are structure as a whole and are positioned at the pretension frame, and an end of alignment pin and push rod stretches out the pretension frame respectively, and spring and pad are sleeved on the alignment pin, and alignment pin is fixed on latch segment on the pretension frame.
Latch segment described in the utility model is provided with the breach that is complementary with the alignment pin head.
Spring and pad that the utility model is sleeved on the alignment pin are positioned by the nut that is positioned at the pad below.
Be threaded on the shaft of push rod described in the utility model.
The pin of going up described in the utility model is perpendicular to horizontal plane.
The head of going up pin and side pin described in the utility model is provided with guide's syringe needle.
The utility model compared with prior art has following beneficial effect: 1, wire clamp is positioned at a side of pretension frame, has saved the balance ball, and structure is more simple; 2, utilize spring can the elasticity that ground wire is positioned at upper and lower wire clamp be automatically adjusted, make its installation more solid and reliable, improved security performance; 3, screwed push rod and spring all can be used for regulating the upper-lower position of alignment pin, both reached can install by hand, the also robotic arm purpose of installing, easy for installation, efficient is high.
