In the first support element 10 and the second support element 20, by unfolded state, (the first support element 10 and the second support element 20 are symmetrical The opposite sides of connection component 70 being arranged on, as shown in Figure 1) variation is folded in one for the first support element 10 and the second support element 20 During the state (shown in Fig. 4) risen, the first articulated section 31 is supported around central shaft 72 (or first adapter 71) and towards second 20 side of part rotates, and opposite first support element 10 of the first limiting section 32 slides, and the second articulated section 41 is around central shaft 72 (or first Adapter 71) and rotated towards 10 side of the first support element, 42 opposite second support element 20 of the second limiting section slides；Meanwhile first Rotation section 52 rotates with respect to the first connecting shaft 73 and the first sliding part 51 opposite first support element in the first sliding groove 11 10 slide (towards the first sliding part 51 farther away from the direction of the end of the first sliding groove 11 17), the second rotation section 62 opposite second Connecting shaft 74 rotates and the second sliding part 61 opposite second support element 20 in second sliding slot 21 is slided and (slided towards second Portion 61 is farther away from the direction of the end of second sliding slot 21 27).

In the first support element 10, by folded state, (the first support element 10 is bonded with the second support element 20 with the second support element 20 Together, as shown in Figure 4) variation is during unfolded state (shown in Fig. 1), and the first articulated section 31 is around central shaft 72 (or the One adapter 71) and rotated towards far from 20 side of the second support element, 32 opposite first support element 10 of the first limiting section slides, and second Articulated section 41 is rotated around central shaft 72 (or first adapter 71) and towards far from 10 side of the first support element, 42 phase of the second limiting section Second support element 20 is slided；Meanwhile 52 opposite first connecting shaft 73 of the first rotation section rotates, and the first sliding part 51 exists It is slided in the first sliding groove 11 with respect to the first support element 10 (towards the first sliding part 51 closer to the end 17 of the first sliding groove 11 Direction), 62 opposite second connecting shaft 74 of the second rotation section rotates and the second sliding part 61 is opposite in second sliding slot 21 Second support element 20 slides in (direction towards the second sliding part 61 closer to the end 27 of second sliding slot 21).

When the first support element 10 is relatively rotated with respect to the second support element 20, since the first articulation piece 30 can be with respect to first Support element 10 slides, and the second articulation piece 40 can be slided with respect to the second support element 20, and the first sliding part 51 being capable of phase First support element 10 is slided, and the second sliding part 61 can occur to slide relatively with respect to the second support element 20, therefore When the first support element 10 is folded by unfolded state or is unfolded by folded state with the second support element 20, first is hinged 30 and first slide assemblies 50 of part will not pull the first support element 10, and the second articulation piece 40 and the second slide assemblies 60 are The second support element 20 will not be pullled.

The fold mechanism 100 of the utility model embodiment further includes following advantageous effect：First, in the first support element 10 With respect in 20 relative rotational motion of the second support element, due to the first articulation piece 30 can opposite first support element 10 slide, And the second articulation piece 40 can be slided with respect to the second support element 20.Therefore, the first articulation piece 30 will not pull first Support member 10, and the second articulation piece 40 will not pull the second support element 20.

Second, since the first articulation piece 30 is pivotally connected together with connection component 70 by the way of being engaged, With respect to the axis direction of central shaft 72 along central shaft 72 opposite slide will not occur for the first articulation piece 30 and the first support element 10； Simultaneously as the second articulation piece 40 is pivotally connected together with connection component 70 by the way of being engaged, and therefore, the second hinge With respect to the axis direction of central shaft 72 along central shaft 72 opposite slide will not occur for 40 and second support element 20 of fitting.
