Described scalable lead I one end is pressed in the wiring hole on peg by nylon screw, its other end It is pressed on by clamping screw and wing nut on the long hangers of cathode substrate.
Described scalable lead II one end is pressed in the wiring hole on peg by nylon screw, its other end It is pressed on by clamping screw and wing nut on the short hangers of cathode substrate.
It is fixed on peg to described peg beam vertical.
Described bolt picks and places groove I and bolt picks and places shape of cross section of the groove II shape of cross section with Inner arc chute It is identical.
The present invention has advantages below compared with prior art:
1st, it is time saving and energy saving, it is practical.The present invention need to only rotate cathode substrate to required when realizing the rotation of cathode substrate Angle, shorten operating process and operating time, alleviate labour.In addition, in the present invention cathode substrate rotation Angle can be adjusted according to being actually needed, and more flexibly, practical value is high.
2nd, it is easily achieved, it is simple to operate.The present invention only need to unscrew fixed negative pole substrate when realizing the rotation of cathode substrate Wing nut, then cathode substrate is rotated to required angle and screws wing nut again.In addition, operating process In cathode substrate need not be removed from hanger, avoid the repeated disassembled and assembled to cathode substrate, simplify operating process, more just Just.
