Abstract
A drive mechanism of a switching device and the switching device are provided. The drive mechanism of the switching device comprises a drive shaft (10), a slide member (20) and an elastic drive assembly (40). The drive shaft is circumferentially provided with a first drive part (12) and a second drive part (14). The slide member has a first limiting part (22), a second limiting part (24) and a transmission part (26). The elastic drive assembly can be connected with the slide member, and can generate an elastic recovery force which acts on the slide member and prevents the slide member from moving. If the drive shaft is at a cutoff position, the first drive part is connected with the first limiting part and the second drive part is connected with the transmission part. If the drive shaft is at a test position, the first drive is connected with the first limiting part and the second limiting part. If the drive shaft rotates from the cutoff position or the test position towards the test position or the cutoff position, the first drive can overcome the elastic recovery force of the elastic drive assembly and push the first limiting part to drive the slide member to move in the slide direction.
