[0033] Working principle: During operation, first place the mounting plate 2 on the insulating rubber mounting base, then loosen the locking nut 33 to release the positioning of the contact pair drive shaft rod 21. Then, drive the adjusting disc 25 to rotate by the adjusting rod 26. The adjusting disc 25 drives the drive shaft rod 27 to rotate inside the positioning disc 30, which can ensure better stability of the drive shaft rod 27 during rotation.
