Top 42 the first spring 33, the seesaw 3 be used for when the arrester 4 drops first spring 33 effect under left side
Push, right end, which rises, to be made second card slot 32 leave second top 51 and fall the fuse.In lightning stroke, keep away
Disengaging bar on thunder device（That is disconnector）Fracture, arrester drop under gravity, further, can be equipped with connecting rope
Preventing from falling earthward and injure by a crashing object, the top pressure there is no the first top on the left of such seesaw, can push under the action of the first spring,
Therefore it can rise on the right side of seesaw, the second card slot is left the second top, fuse can fall under gravity, prevent secondary
Lightning stroke, can be fuse switch as preferable fuse, and the present invention provides combined type lightning protection fuse, is cut with scissors on its pillar
Seesaw is connected to, seesaw both ends are opposite to be arranged on pillar both sides and be arranged with the first card slot and the second card slot, arrester upper end and first
Card slot is engaged by clamping, and lower end is equipped with and is connected by departing from bar with mounting bracket, and departing from fracture when bar is used to be struck by lightning makes arrester
Drop；Fuse upper end is engaged by clamping with the second card slot, and fuse lower end is hinged with mounting bracket, and seesaw is used to fall in arrester
Left side pushes under the effect of the first spring when falling, and right end, which rises, to be made the second card slot leave the second top and fall fuse.
During lightning stroke, arrester, which drops, drives seesaw to rise, and falling fuse prevents secondary lightning stroke.It is simple in structure, it is easy for installation, use
Safety.
In the present embodiment, as shown in the figure, being correspondingly provided with installing plate 21 with the seesaw 3 on the pillar 2, spiral shell is further included
Bolt 211,211 lower end of bolt sequentially passes through the seesaw 3 and installing plate 21 and equipped with the nut 212 being threadedly coupled, described
211 upper end of bolt is arranged on the top of seesaw 3 and is equipped with door 213, and institute is equipped between 3 opposite face of the door 213 and the seesaw
State the first spring 33.It can not only realize the pressure downward to seesaw, when necessary, can also be lifted up by adjusting bolt to adjust
