Detailed ways

As shown in the accompanying drawings, the multi-section hinge device proposed by the utility model is composed of a fixed part 1 and a rotary part 2, wherein:

The fixing part 1, as shown in Fig. 1 to Fig. 3, is constituted as a hollow cylinder, and a plurality of grooves 11 are arranged around the inner wall at one end thereof, and each of the grooves 11 can be constituted as a continuous concave-convex wavy structure. The bottom of the plurality of grooves 11 is provided with an inner convex ring 12 with a smaller diameter to form a through hole 121, and an arc-shaped gap with a larger diameter is provided at the inner ring wall of the inner convex ring 12 to form a guide groove 13. The two ends of the guide groove 13 respectively form a stopper 131, 132 (see Figures 4 and 5); wherein, the appearance configuration of the fixing member 1 is not limited to a specific shape, and can be circular, rectangular or other shape, and the wall at the other end of the fixing part 1 can be provided with slots 14 and several projections 15, which can be assembled and combined with other items.
