In order to solve the above technical problems, the technical scheme that the utility model uses is：There is provided it is a kind of it is adjustable it is anti-every
Pass conjunction instrument by mistake is left, including support bar, anchor ear, the top of support bar are provided with buckle, anchor ear is adjustable structure or integral type
Structure, snap ring is provided with anchor ear side, and buckle is connected with snap ring.
In one preferred embodiment of the utility model, the adjustable anti-disconnecting switch, which misses conjunction instrument, also to be included insulating adding
Stock, insulated lengthened bar are threadedly coupled with support bar, to be actually needed the length that support bar is adjusted flexibly according to scene.
Further, buckle is in upside down funnel shape, including opening portion, guiding bar, cross bar, the bottom of guiding bar and opening portion
Connection, cross bar are horizontally fixed on opening portion and the junction of guiding bar, and opening portion is fastened on the top of support bar.
Further, snap ring is in the cylindrical shape of upper and lower opening, and a groove is provided with the side wall of snap ring.Buckle is matched somebody with somebody with snap ring
When closing connection, the guiding bar of buckle is passed through in the middle part of snap ring, and cross bar is stuck in the groove of snap ring just.
Further, the middle part of adjustable hoop or both wings are divided into some sections, are connected between section by nut, so as to
The length of adjustable hoop is adjusted by rotary nut, to adapt to the disconnecting switch of different sizes conductive arm up and down.
Further, the bottom of support bar, the one or both ends of insulated lengthened bar are equipped with screw thread, for lengthening support bar
Length.
The beneficial effects of the utility model are：The utility model is simple in construction, using flexible, conveniently, can be according to power transformation
Stand being actually needed of Overhaul site, freely adjust the length of support bar and anchor ear, pass through mechanical snap and fix the upper of disconnecting switch
Lower conductive arm, facilitate the replacing service work of disconnecting switch universal joint and bearing, effectively prevent disconnecting switch in maintenance process
Mistake close, improve station work security.
