[0028] For a specific implementation example, please refer to Implementation Example 1. Figures 1-8 This utility model is a bidirectional opening and closing multi-link mechanism, including a main rod 1; the projection of the main rod 1 in the vertical direction is a regular polygon; a sliding groove 2 is opened inside the main rod 1; a bidirectional lead screw 3 is rotatably arranged on the inner wall of the sliding groove 2; a regular polygon plate 4 is symmetrically threaded and rotatably arranged on the periphery of the bidirectional lead screw 3; the regular polygon plate 4 slides in cooperation with the inner wall of the sliding groove 2; the sliding directions of the two regular polygon plates 4 are opposite; a plurality of suspension components 5 are evenly arranged between the top end of the main rod 1 and the adjacent regular polygon plate 4; a plurality of support components 6 are evenly arranged between the bottom end of the main rod 1 and the adjacent regular polygon plate 4.

[0029] Specifically, a number of guide grooves 7 are evenly provided on the side of the main rod 1; a limiting groove 8 that communicates with the inside of the sliding groove 2 is provided through the inner wall of the guide groove 7; a number of limiting blocks 9 that slide in cooperation with the limiting groove 8 are evenly fixed on the side of the regular polygonal plate 4; and a guide plate 10 that slides in cooperation with the guide groove 7 is fixed on the side of the limiting block 9.

[0030] Furthermore, the top of the main rod 1 is fixed to the micro motor 26; the output end of the micro motor 26 is fixedly connected to the top of the bidirectional lead screw 3.

[0031] The operation process in this embodiment is as follows: the clothes hanger... Figure 8 Transported to the location of use in the condition shown. Figure 8 The upper and middle row of guide plates 10 (connected to the suspension assembly 5) are attached to the lower row of guide plates 10 (connected to the support assembly 6), and the upper and lower regular polygonal plates 4 are attached to each other.

[0032] When the clothes hanger is unfolded, the micro motor 26 is started to drive the bidirectional lead screw 3 to rotate, which in turn drives the two corresponding regular polygonal plates 4 to slide away from each other along the inner wall of the slide groove 2, which in turn drives the corresponding limiting block 9 to slide along the limiting groove 8, which in turn drives the guide plate 10 to slide along the inner wall of the guide groove 7, which in turn drives the upper guide plate 10 and the lower guide plate 10 to move away from each other, and the guide plate 10 drives the corresponding suspension component 5 and support component 6 to open up, and the support component 6 is placed close to the ground. At this time, the clothes hanger can be stably placed on the ground, and clothes can be hung and taken out through the suspension component 5.

[0033] In this embodiment, the clothes hanger is set to be retractable and expandable, so that the clothes hanger is transported to the use site in a retracted state, and the user only needs to start the micro motor 26 to drive the bidirectional screw rod 3 to rotate, so that the hanging assembly 5 and the supporting assembly 6 are expanded, and the clothes hanger can be easily obtained for use. Compared with on-site assembly of multiple connecting rods, it is more convenient and practical.

[0034] Specific embodiment two, please refer to Figures 1-8 On the basis of the specific embodiment one, the top end of the main rod 1 is uniformly provided with a plurality of first installation grooves 11; the hanging assembly 5 comprises a first connecting rod 12 rotatably arranged in the inner wall of the first installation groove 11; the surface of the guide plate 10 is symmetrically fixed with a first installation block 13; a second connecting rod 14 is rotatably arranged between the two first installation blocks 13.

[0035] Specifically, the first connecting rod 12 is fixed with a first L-shaped plate 15 on the side surface; the first L-shaped plate 15 is fixed with a first connecting shaft 16 penetrating through the side surface; the second connecting rod 14 is provided with a first rotating groove 17 penetrating through the side surface and matched with the circumferential surface of the first connecting shaft 16; a plurality of hanging holes 18 are uniformly and penetratingly provided on the surface of the first connecting rod 12 and the second connecting rod 14.

[0036] Further, the bottom end of the main rod 1 is uniformly provided with a plurality of second installation grooves 19; the supporting assembly 6 comprises a third connecting rod 20 rotatably arranged in the inner wall of the second installation groove 19; the surface of the guide plate 10 is symmetrically fixed with a second installation block 21; a fourth connecting rod 22 is rotatably arranged between the two second installation blocks 21.

[0037] Further, the third connecting rod 20 is fixed with a second L-shaped plate 23 on the side surface; the second L-shaped plate 23 is fixed with a second connecting shaft 24 penetrating through the side surface; the fourth connecting rod 22 is provided with a second rotating groove 25 penetrating through the side surface and matched with the circumferential surface of the second connecting shaft 24.

[0038] The operation process of this embodiment is: the density of the threads on both ends of the bidirectional screw rod 3 is different, the density of the threads connected with the hanging assembly 5 is greater than the density of the threads connected with the supporting assembly 6, so when the bidirectional screw rod 3 is rotated, the speed of the regular polygon plate 4 connected with the hanging assembly 5 sliding in the sliding groove 2 is less than the speed of the regular polygon plate 4 connected with the supporting assembly 6 sliding in the sliding groove 2.

[0039] First, start the micro motor 26 to drive the bidirectional screw rod 3 to rotate, and then drive the regular polygon plate 4 to move along the inner wall of the sliding groove 2, and then drive the limiting block 9 and the guide plate 10 to slide, and then drive the second connecting rod 14 to move, while the other end of the second connecting rod 14 expands outward, and then drives the first connecting shaft 16 to rotate, and then drives the first L-shaped plate 15 to rotate, and then drives the first connecting rod 12 to rotate along the inner wall of the first installation groove 11, and then makes the hanging assembly 5 complete expansion.

[0040] Meanwhile the fourth connecting rod 22 is driven to move by the guide plate 10, and meanwhile the fourth connecting rod 22 expands outward at the other end, thereby driving the second connecting shaft 24 to rotate, thereby driving the second L-shaped plate 23 to rotate, thereby driving the third connecting rod 20 to rotate along the inner wall of the second mounting groove 19, thereby enabling the support assembly 6 to complete the expansion.

[0041] In the process of expanding the suspension assembly 5 and the support assembly 6, the speed of the corresponding regular polygon plate 4 sliding of the support assembly 6 is greater than the speed of the corresponding regular polygon plate 4 sliding of the suspension assembly 5, thereby the degree of expansion of the suspension assembly 5 is less than that of the support assembly 6, that is, as shown in the figure, the contact area of the support assembly 6 with the ground is larger, and the clothes hanger is more stable, and meanwhile the distance between the first connecting rod 12 and the second connecting rod 14 of the suspension assembly 5 will not be too small, thereby being suitable for more clothes.
