Manual locking mechanism of high-voltage isolating switch

The utility model provides a manual locking mechanism of a high-voltage isolating switch, and belongs to the field of electrical equipment. The problem that an existing mechanism is poor in safety is solved. The manual locking mechanism of the high-voltage isolating switch comprises a supporting plate and a baffle vertically and fixedly arranged on the front side of the supporting plate, a front-back through manual operation hole is formed in the middle of the baffle, a guide plate is vertically and slidably arranged between the baffle and the supporting plate, and a front-back through receding hole used for being aligned with the manual operation hole is formed in the middle of the guide plate. A positioning hole penetrates through the lower end of the baffle front and back, a locking hole capable of being aligned with the positioning hole penetrates through the lower end of the guide plate front and back, and the same positioning pin is inserted into the locking hole and the positioning hole which are align
