By adopting technique scheme, twisting control part drives top board to rotate in a circumferential direction, when described top board rotates in a circumferential direction certain angle, described linkage portion is stirred fixed lever, described fixed lever is laterally dialed to inconsistent with rectangular channel inwall time, described two springs bar that is fixed is squeezed to largest deformation amount, when two springs are extruded after energy storage, spring is in order to reset, the elastic potential energy of storage is discharged, promotion fixed lever moves to another direction of rectangular channel rapidly, described fixed lever promotes the direction that terminal block moves to fixed lever simultaneously and moves, reach dividing of terminal block, the control object of closing a floodgate, adopt this design, the feature of using spring storage power and releasing energy, avoided the operate miss causing because of manually-operated speed, and use two springs to push terminal block motion simultaneously, terminal block is being divided, in the process of closing a floodgate, reaction speed is faster, further improved the speed that isolating switch is cut off the electricity supply, prevent because operated the situation that causes that slowly isolating switch damages.
Not only that, described two springs are arranged at respectively the both sides up and down of terminal block, make terminal block in the process of dividing, closing a floodgate, that moves is more steady, there will not be terminal block minute, the upper and lower both sides of terminal block are caused by force unbalance in making process the unsettled situation of terminal block movement locus, also reduced the possibility that causes the accident appearance that isolating switch damages because movement locus is unstable.
Described control part passes upper cover and controls for outside, externally just can carry out dividing, closing a floodgate of isolating switch by direct control control part, reaches the effect of handled easily.
The utility model is further set to: the long edge of described rectangular channel longitudinally arranges.
By adopting technique scheme, can be so that the action that less angle just can make terminal block divide, close a floodgate be rotated in operating side by the longitudinal setting in long edge of rectangular channel, that is to say, carry out isolating switch minute, can react faster when closing a floodgate, improve the reaction speed of isolating switch, further reduced the possibility of the damage of isolating switch.
The utility model is further set to: described linkage portion arranges in the form of sheets.
By adopting technique scheme, linkage portion is made as to sheet, make the internal structure of isolating switch compacter, reduced the overall structure of isolating switch, make isolating switch miniaturization more.
