By adopting technique scheme, when needs hands off device, initial condition is plugged in the first handle bar pull-out in the second handle bar, lengthen the length of the second handle bar, because be that the second handle bar is fixedly connected with Shell of circuit breaker pivot pin, distance stress point is elongated, thus improve the moment of torsion of the second handle bar, reach labour-saving effect, again because the first handle bar is plugged in the second handle bar, during use, only need the first handle bar to be pulled out in the second handle bar part, easy to operate, when first handle bar is pulled out in the second handle bar, length twitches the first handle bar by card, fixture block is slippage in chute, until fixture block and draw-in groove clamping, increase the stability of the first handle bar and the second handle bar, first handle bar shrinks in the second handle bar in initial condition constantly, save taking up room of the first handle bar, after iron plate is threaded off, the landing of iron plate one end and contact, illuminating lamp and storage battery is made to form a closed circuit, illuminating lamp works, because, circuit breaker is generally that manual driving handle closes after disconnecting, illuminating lamp is arranged on handle, clearly can tell the position of handle in the dark, handled easily.

The utility model is set to further: be provided with in described second handle bar and be connected tension spring with the first handle bar.

By adopting technique scheme, be provided with in second handle bar and be connected tension spring with the first handle bar, for being pulled out to the outer part of the first handle bar at the first handle bar and after completing close circuit breaker, first handle bar is returned to initial condition, while easy to operate, preventing from, because forgetting, the first handle bar is returned to initial condition, encountering the first handle bar by mistake and making it from fractureing with the second handle bar junction or being opened by circuit breaker, impact normally works.

The utility model is set to further: described second handle bar is provided with some reinforcements, and some reinforcements of telling are interspersed.

By adopting technique scheme, the second handle bar being distributed with some the reinforcements be crisscross arranged, for increasing the intensity of the second handle bar, preventing it from use fractureing, increase it and be provided with the life-span.

The utility model is set to further: described first handle bar and the second handle bar are evenly made up of vulcanie, all with layer of metal sheet on the first handle bar and the second handle bar, sheet metal is electroplate with one deck insulating material.

By adopting technique scheme, the the first handle bar be made up of vulcanie and the second handle bar, quality is light, old low, and hardness is high, long service life, all with layer of metal sheet on the first handle bar and the second handle bar, in the useful life of both hardness raisings of further increase by first handle bar and the second handle bar, one deck insulating material that sheet metal is electroplated, for insulation, prevents electric leakage from damaging human body.
