Abstract:

A rotary shaft (100) and a terminal device (200) comprising the rotary shaft (100). The rotary shaft (100) comprises a central shaft (10), a first support (20), a second support (30), an elastic member (60) and a concave-cam assembly (50); the first support (20) is rotatably arranged on the central shaft (10); the second support (30) is fixed on the central shaft (10); the elastic member (60) is disposed on the central shaft (10); the elastic member (60) has a hollowed-out shape and is an integrated structure; the concave-cam assembly (50) is disposed on the central shaft (10), and the concave-cam assembly (50) may enable the elastic member (60) to deform; when the first support (20) rotates relative to the second support (30), the concave-cam assembly (50) produces a pressing force that acts on the elastic member (60), so that the hollowed-out elastic member (60) deforms, so that a certain included angle exists between the first support (20) and the second support (30). The elastic member (60) of the rotary shaft (100) is an integrated structure, which is convenient for installation and improves installation efficiency. The hollowed-out elastic member (60) is frequently used, and the elastic member (60) has a constant force characteristic.
