The invention discloses an automatic locking mechanism of a rotary shaft. A cylindrical hole is formed in a locking support. A toothed cylinder sliding block is arranged in the cylindrical hole through a linear bearing. A notch is formed in the front end of the toothed cylinder sliding block, and a potentiometer induction sheet is arranged in the notch. A sliding groove is formed in the rear end of the toothed cylinder sliding block. A limiting nut is arranged in the sliding groove. A base body of a push rod base is fixed to the rear end of the toothed cylinder sliding block. A guide through hole is formed in the push rod base. The front end of a guide stud penetrates through the guide through hole and is in threaded connection with the limiting nut. A linear motor is fixedly connected with the rear end of the locking support through a motor mounting base. A power output shaft of the linear motor is fixedly connected with the guide stud in a coupling hole. One end of a spring is connected with the base body of the push rod body, and the other end of the spring is connected with the positioning face of the motor mounting base. A potentiometer is fixed to the locking support, the potentiometer induction sheet is connected with the induction end of the potentiometer, and the control signal output end of the potentiometer is connected with a control signal input end of the linear motor. The automatic locking mechanism of the rotary shaft is high in environmental adaptability and compact in structure.
