A joint locking mechanism of a passive robotic arm includes: an output assembly, including a joint output shaft, and a friction disk fixed to the joint output shaft; a braking assembly, including a threaded shaft arranged coaxially with the joint output shaft, a threaded sleeve threaded to the threaded shaft, a rotary disk connected fixedly to the threaded shaft, an end cap rotatable relative to the rotary disk, and a scroll spring generating a rotational force on the threaded shaft. The scroll spring has one end connected fixedly to the end cap and the other end connected to the rotary disk or the threaded shaft. The threaded sleeve is abutted tightly against the friction disk.
