Summary of the invention
The object of the invention is to overcome above deficiency, provide a kind of permanent magnetic vacuum breaker operating grip, it is the structure with the integrated design of permanent magnetic vacuum breaker body, and the reliability that can permanent magnetic vacuum breaker be operated is greatly improved.
For achieving the above object, this invention takes following technical scheme.
A kind of permanent magnetic vacuum breaker operating grip, containing cantilever and handle, it is characterized in that, be provided with rotating disk in the front end of described cantilever, the inwall of described rotating disk is provided with roller, and the rotating shaft that described roller can block permanent magnetic vacuum breaker makes the front end of described cantilever be connected with described rotating shaft; Be provided with the second positioning threads in the front portion of described cantilever, be provided with the first positioning threads at the rear portion of described cantilever; Described handle is tube-in-tube structure, is provided with internal thread at described handle aperture end, and described internal thread is corresponding spiral link structure with described first positioning threads and the second positioning threads; Described taper knob is connected on described cantilever.
Further, the length of described cantilever is 2/3rds of described decreased food.
Further, in described handle, spring is installed.
Further, when described handle is connected with described second positioning threads spiral by internal thread, it is a bit of that permanent magnetic vacuum breaker panel is only stretched out in the rear end of described handle.
Further, when described handle is connected with described first positioning threads spiral by internal thread, the major part of described handle rear end stretches out the panel of permanent magnetic vacuum breaker.
Further, described roller and rotating shaft adopt overrun clutch structure.
The good effect of a kind of permanent magnetic vacuum breaker operating grip of the present invention is:
By permanent magnetic vacuum breaker operating grip and the integrated design of permanent magnetic vacuum breaker body, operating grip is contracted in circuit breaker panel when non operating state, when needs manual operation maintenance permanent magnetic vacuum breaker, operating grip is launched to operate, make the globality of permanent magnetic vacuum breaker stronger, decrease the workload of permanent magnetic vacuum breaker operational management, make permanent magnetic vacuum breaker operationally more reliable.

Embodiment
Provide the embodiment of a kind of permanent magnetic vacuum breaker operating grip of the present invention below in conjunction with accompanying drawing, but enforcement of the present invention is not limited to following execution mode.
See Fig. 2.A kind of permanent magnetic vacuum breaker operating grip, containing rotating disk 21, roller 22, cantilever 24, handle 25, spring 26, first positioning threads 28 and the second positioning threads 29.A length is adopted to be the cantilever 24 of handle 25 length 2/3rds.In the front end of described cantilever 24, rotating disk 21 is set, the inwall of described rotating disk 21 is provided with roller 22, described in the rotating shaft 23(that described roller 22 can block permanent magnetic vacuum breaker, roller 22 adopts overrun clutch structure with described rotating shaft 23), the front end of described cantilever 24 is connected with described rotating shaft 23.Second positioning threads 29 should be set in the front portion of described cantilever 24 (position near described cantilever 24), the first positioning threads 28 is set at the rear portion of described cantilever 24.
Described handle 25 is a tube-in-tube structure, arranges internal thread at described handle 25 mouthfuls of ends, and described internal thread is corresponding spiral link structure with described first positioning threads 28 and the second positioning threads 29.Described handle 25 to be socketed on described cantilever 24 and in described handle 25, a spring 26 to be installed.When described handle 25 is connected with described second positioning threads 29 spiral by internal thread, permanent magnetic vacuum breaker panel 27 a bit of (see Fig. 2) is only stretched out in the rear end of described handle 25.When described handle 25 is connected with described first positioning threads 28 spiral by internal thread, the major part of described handle 25 rear end stretches out the panel 27(of permanent magnetic vacuum breaker see Fig. 3).
