Further, the positioning convex one has four, and each two is one group, is symmetrically distributed in the two of lockset shell
End.
Further, the two ends of the medium position of the mounting seat are respectively provided with one gradually to the recessed of mounting seat central concave
Groove.
It is an advantage of the current invention that：In the present invention, the lockset in the present invention when mounted, is reserved on two conductive arms
Location hole, then using the cooperation of positioning convex and location hole, first can be arranged on lockset between two conductive arms, finally make
The installation of lockset is completed by being tightened by bolts two conductive arms, in dismounting, only the bolt on two conductive arms need to be turned on,
Lockset can be removed, it is very convenient.
By being related to groove structure in the middle part of mounting seat, on the basis of its structural strength is ensured, effectively mitigate peace
The overall weight of dress seat.
This lock structure is simple, and parts are few, and corresponding overall weight is light, is effectively reduced the overall weight of disconnecting switch
Amount.
