A gimbal assembly and a handheld gimbal using same. The gimbal assembly comprises a first rotating shaft section (41) and a first connecting arm (42). One end of the first rotating shaft section (41) is rotatably connected to a first connecting device (30), and the other end of the first rotating shaft section (41) is connected to a second connecting device (43) by means of the first connecting arm (42). The first rotating shaft section (41) is further pivotally connected to the first connecting arm (42), so that the first rotating shaft section (41) is capable of rotating with respect to the first connecting arm (42). Thus, the first rotating shaft section (41) and the first connecting arm (42) are switched between a state of being superimposed and a state of being separated from each other. Therefore, the gimbal assembly is switched between a folded state and an unfolded state.
