Room 2 includes the vacuum arc-extinguishing chamber contact 22 of connecting rod 21 and the rear end of connecting rod 21；The front end of connecting rod 21 by attaching nut 15 with
The rear end of insulated tension pole 11 connects；Characterized in that, the rear end of pull bar adjusting set 13 is provided with the first flange 16, insulated tension pole 11 is provided with
Second flange 17, is provided with preceding torsion spring 18 and rear torsion spring 19 between the first flange 16 and the second flange 17, the preceding front end of torsion spring 18 and the
One flange 16 is connected, and the rear rear end of torsion spring 19 is connected with the second flange 17, and the preceding rear end of torsion spring 18 extends obliquely, and holds in its back-end
Portion connects vertical extension 181, and the rear front end of torsion spring 19 extends obliquely, and extends laterally section 191 in the connection of its forward end.
Further, preceding torsion spring 18 rotate to vertical extension 181 it is relative with extending laterally section 191 when, vertical extension 181
Middle height is consistent with extending laterally section 191, and the preceding width of torsion spring 18 is consistent with the rear width of torsion spring 19.
The beneficial effects of the utility model are：
During operation, insulated tension pole 11 is connected and is driven with pull bar adjusting set 13 by freewheel clutch 12.When adjusting the excess of stroke,
Adjusting nut 14 is screwed, now freewheel clutch 12 separates insulated tension pole 11 and pull bar adjusting set 13, and preceding torsion spring 18 is with after
Torsion spring 19 uses Split type structure, when the vertical rotary collision of extension 181 is to when extending laterally section 191, vertical extension 181 by
The stop of section 191 is extended laterally, the torsion that the rotating band of adjusting nut 14 comes is greatly reduced, reduces vacuum arc-extinguishing chamber contact 22
Rotate and cause vacuum interrupter to damage.
