Electric spring mechanism and high-voltage switch

The invention relates to an electric spring mechanism and a high-voltage switch, and belongs to the technical field of high-voltage electrical equipment. The electric spring mechanism comprises a machine shell, an output shaft, a driven connecting lever, a driving connecting lever and an opening and closing spring. The electric spring mechanism further comprises a worm gear or a gear driving the driving connecting lever to rotate. The electric spring mechanism further comprises a locking device, the locking device comprises a cam part assembled on the output shaft in a rotation stopping mode, the cam part is located in the interval space between the worm gear or the gear and the machine shell, the locking device further comprises a collision rod assembled on the machine shell in a telescopic mode in the axial direction of the output shaft, and the collision rod is located on one side of the output shaft. The striking rod has an extending state in which the striking rod extends out to be matched with the cam p
