Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] It should also be understood that the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0026] It should be further understood that the term " / and" used in the specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0027] Please refer to Figure 1 - Figure 2 , the present invention provides a linkage structure 10, including a first connecting member 11, a second connecting member 12 and an adjusting assembly 20. The adjusting assembly 20 is respectively rotatably connected to the first connecting member 11 and the second connecting member 12. The first connecting member 11 is movably connected relative to the second connecting member 12, and the adjusting assembly 20 is in gear engagement with the first connecting member 11 and the second connecting member 12 respectively.

[0028] The first connecting member 11 is provided with first teeth 111, and the second connecting member 12 is provided with second teeth 121. The adjusting assembly 20 includes a first sliding member 21, a second sliding member 22 and a gear 23. The first sliding member 21 and the second sliding member 22 are provided with third teeth 24 longitudinally and transversely.

[0029] The first sliding member 21 and the second sliding member 22 move towards each other or move in opposite directions. When the first connecting member 11 or the second connecting member 12 rotates, the corresponding meshed first sliding member 21 or second sliding member 22 is driven to move, thereby driving the gear 23 to rotate. The gear 23 then correspondingly drives the second sliding member 22 or the first sliding member 21 to move, and then correspondingly drives the second connecting member 12 or the first connecting member 11 to rotate, achieving the effect of synchronous rotation of the first connecting member 11 and the second connecting member 12.

[0030] The linkage structure 10 further includes a rotating shaft 25. An elastic member 26 is sleeved on the rotating shaft 25. Two ends of the elastic member 26 are respectively connected to the first connecting member 11 and the second connecting member 12. The rotating shaft 25 is arranged between the first connecting member 11 and the second connecting member 12. In this embodiment, the elastic member 26 is a torsion spring. By respectively abutting against the first connecting member 11 and the second connecting member 12 at two ends of the torsion spring, it is convenient for the first connecting member 11 and the second connecting member 12 to reset when the torsion spring rebounds, facilitating the storage and folding of the bracket.

[0031] Please refer to Figure 2 and Figure 3 As shown in, the adjusting assembly 20 further includes a base 30. The base 30 protrudes and extends with a first connecting plate 31 and a second connecting plate 32. The rotating shaft 25 is respectively connected to the first connecting plate 31 and the second connecting plate 32. The first connecting member 11 and the second connecting member 12 can rotate relative to the first connecting plate 31 and the second connecting plate 32. The adjusting assembly is arranged on the base 30.

[0032] The base 30 is provided with a mounting member 33. The mounting member 33 is provided with a receiving groove 34 for receiving the first sliding member 21, the second sliding member 22 and the gear 23.

[0034] A locking assembly 80 is disposed at the connection between the first connecting member 11 and the third connecting member 60 and at the connection between the second connecting member 12 and the fourth connecting member 70. The locking assembly 80 includes a first fastener 81, a second fastener 82, a first ratchet 83 and a second ratchet 84 that are coaxially connected. The first ratchet 83 is sleeved on the first fastener 81, the first ratchet 83 and the second ratchet 84 are meshed and connected, the second ratchet 84 is elastically connected to the inner wall of the first connecting member 11, the first ratchet 83 and the second ratchet 84 are respectively sleeved on both sides of the third connecting member 60, and the first ratchet 83 and the second ratchet 84 are respectively sleeved on both sides of the fourth connecting member 70.

[0035] The first fastener 81 is provided with an abutting member 811 and a connecting shaft 812 that are connected to each other. The abutting member 811 abuts against or separates from the first ratchet 83, and the connecting shaft 812 passes through the first ratchet 83 and abuts against or separates from the second ratchet 84.

[0036] When the teeth of the first ratchet 83 and the second ratchet 84 are meshed, the first connecting member 11 and the third connecting member 60 are locked and cannot rotate relative to each other, and the second connecting member 12 and the fourth connecting member 70 are locked and cannot rotate relative to each other. When the first fastener 81 is pressed to separate the first ratchet 83 and the second ratchet 84, at this time, the first connecting member 11 and the third connecting member 60 can move relative to each other, and the second connecting member 12 and the fourth connecting member 70 can move relative to each other. When the pressing force of the first fastener 81 is released, since the second ratchet 84 is elastically connected to the inner wall of the first connecting member 11, the second ratchet 84 rebounds and moves to mesh with the first ratchet 83.

[0037] Please continue to refer to Figure 5 , in this embodiment, the third connecting member 60 and the fourth connecting member 70 are driven by tooth engagement, and the design of tooth engagement is adopted to synchronize the linkage of the third connecting member 60 and the fourth connecting member 70.

The third connecting piece is rotatably connected to the fourth connecting piece. The support plate is arranged on the third connecting piece and the fourth connecting piece. Thus, when the first connecting piece, the second connecting piece, the third connecting piece and the fourth connecting piece swing, they can respond simultaneously, and the supporting action is relatively stable. At the same time, when the third connecting piece, the fourth connecting piece, the first connecting piece and the second connecting piece are in a vertical state, a dead point position appears between the first connecting piece and the third connecting piece and between the second connecting piece and the fourth connecting piece. And under the action of the indirect engagement between the first connecting piece and the second connecting piece and the direct engagement between the third connecting piece and the fourth connecting piece, there will be no left-right swing in the vertical state. And under the action of the dead point position, the support plate can be stably and reliably supported, and the support plate has a large load-bearing capacity, which can make it more convenient for users to study or work in various places.
