Bottom be provided with for clamping installation groove.
As a kind of improvement of the present utility model, the both sides of the inwall of the groove are respectively arranged with deck and top plate, institute
State top plate and be connected with the second spring being arranged in the chuck.
As further improvement of the utility model, the both ends of the chuck are provided with the peace for installing binding post
Fill hole.
Further improved as of the present utility model, fixed column, the contact shell fragment winding are provided with the boss
In the fixed column.
Further improved as of the present utility model, fore-set is provided with the chuck, the fore-set withstands described touch
One end of head shell fragment.
Further improved as of the present utility model, the groove width of the groove is 60 centimetres ~ 80 centimetres.
Further improved as of the present utility model, the groove width of the groove is 71 centimetres.
Further improved as of the present utility model, the boss is integrally formed with the chuck.
In the utility model, the chuck of boss and the lower section in boss is set on base body, is provided with boss tactile
Head shell fragment and the first spring for being connected with contact shell fragment, facilitate it to install lock and are attached, be provided with chuck first every
Arc wall and the second arc separating wall, arc-control device is installed to it and carries out arc isolation；Using the groove in chuck block admittedly simultaneously
Dingan County fills.
