Abstract
A rotating self-locking actuator includes a housing, a self-locking device, and a motor shaft at least one end of which extends out of the housing. The self-locking device includes a pin rod, a friction cap which is disposed outside the housing and sleeved over the motor shaft, and an arc-shaped groove extending helically about an axial direction of the motor shaft and provided on a side wall of the friction cap. The pin rod rotates synchronously with the motor shaft and is sliding-fitted with the arc-shaped groove. The motor shaft causes the pin rod to rotate such that the friction cap is driven by the pin rod to move axially to contact the housing, whereby friction self-locking is enabled, and the friction cap is driven by the pin to move axially to detach from the housing, whereby the friction self-locking is released.
