The invention discloses a transmission device of an electric control mechanism for an isolating switch, the transmission device comprises an isolating base, a transmission assembly and a locking assembly, when the transmission device is connected, a lifting moving block moves downwards, and a driving connecting rod and an insulating connecting rod drive a switch blade to rotate downwards to a horizontal state to realize circuit connection; in the process, the locking moving rod automatically moves towards the direction of the knife switch and completes limiting, and the knife switch is prevented from being turned upwards accidentally to be disconnected. During disconnection, the lifting moving block firstly moves downwards, the locking moving rod is driven by the moving sleeve to automatically release limiting, then the lifting moving block moves upwards, the knife switch is driven to rotate upwards to achieve disconnection, automatic locking during connection and automatic unlocking before disconnection are achieved through pure mechanical linkage, an electromagnetic lock or an electrical control element is not needed, electrical fault points are reduced, and the reliability of the device is improved. The reliability of long-term operation under severe working conditions is remarkably improved, accidental disconnection of the knife switch caused by vibration or misoperation is effectively prevented through mechanical limiting, and the stability of circuit connection and operation safety are guaranteed.

The utility model discloses a kind of self-locking structures for servo electric clamping jaw, including servo motor, the lower end of servo motor is provided with gear box, and the side of servo motor is located at the upper position of gear box and is provided with cylinder barrel, the upper end of cylinder barrel is provided with self-locking box, the side of self-locking box is equipped with clamping jaw structure, the inside of gear box is provided with first synchronous wheel, the first synchronous wheel is installed on the power shaft of servo motor, and the outside of first synchronous wheel is sleeved with synchronous belt, one end of synchronous belt is sleeved on synchronous wheel. The design is used for the clamping of automatic production line, without the case of self-locking, servo motor can be controlled to be disabled, clamping at any angle, when the workpiece needs to be self-locked, through the cooperation of driving shaft, first connecting rod and second connecting rod, the self-locking function is realized, and the reliable self-locking function can ensure that the clamping jaw maintains the grabbing state in the case of sudden situation, avoids material falling, and improves operation safety and reliability.
