When the limit spring 55 is in an initial state, that is, when the limit spring 55 is not extruded by the first plate 52 and the stop block 54, the stop block 54 is opposite to the opening position of the first hole on the second connecting block 22, at this time, the stop block 54 keeps the limit pin 41 in the first shaft 23, in the process of adjusting the opening postures of the first component 1 and the second component 3 from the first state or the second state to the locking posture, when the second connecting block 22 moves between the two protruding parts 14, due to the limitation of the two groups of protruding parts 14, the second connecting block 22 moves along the limitation direction of the protruding parts 14, that is, the direction of the right trapezoid short side, in this process, the first plate 52 passes through the through groove on the limit block 15, and the second plate 53 cannot pass through the through groove to reach one side of the limit block 15 close to the first shaft 23 due to the length of the through groove, at this time, the limit shaft 51 is limited by the second plate 53, cannot follow the second connecting block 22, that is also unable to move continuously, that is, the second connecting block 22 and the limit shaft 51 generates relative displacement, when the second connecting block 22 moves from the first hole on the second connecting block 22, and then, the stop block 54 moves along the limitation direction of the protruding parts 14, that is limited by the first hole, that is not, the limit pin 22, namely, can not reach the limit pin 41, and reach the limit pin 13, and can not reach the limit position of the limit pin 13, which is completely, because of the limit pin 41, and can reach the limit plug-stop block 41, and the limit piece 13, and can reach the limit position, and the limit piece, and can reach the limit stop piece, and the limit position, and can completely, and can reach the limit position, and the limit stop element.

The setting of the limiting mechanism 5 can ensure that the limiting pin 41 is always limited in the first shaft 23 before the first member 1 and the second member 3 are adjusted from the open posture to the locking posture, and the limiting pin 41 does not need to be manually pressed in the first shaft 23, so that the installation is more convenient.

Still further, in order to facilitate the cancellation of the restriction of the second connection block 22 during the disassembly of the building, the insertion hole 13 may penetrate the side wall of the first member 1, when the restriction of the second connection block 22 needs to be cancelled, the stopper pin 41 is pushed to the inside of the first shaft 23 through the insertion hole 13, when the stopper pin 41 completely enters the first shaft 23, the position of the second connection block 22 is not restricted, the second connection block 22 may be moved out from the left side of the boss 14 shown in fig. 4, the restriction of the second connection block 22 is cancelled, and the locking posture of the first member 1 and the second member 3 is adjusted to the open posture from the first state or the second state.

In addition, during the process of adjusting the first member 1 and the second member 3 from the locking posture to the opening posture, the second connecting block 22 moves outwards along the limiting direction of the protruding portion 14, that is, the second connecting block 22 moves towards the direction of the second member 3 along the short side of the right trapezoid, at this time, due to the fact that the limiting spring 55 is in a compressed state, along with the movement of the second connecting block 22, the limiting spring 55 gradually recovers and pushes the stop block 54 to block the first hole again, so that the limiting pin 41 can be blocked inside the first shaft 23 by the stop block 54 while the second connecting block 22 moves outwards from the notch 11, and when the explanation needs to be made, the side wall of the notch 11 is matched with the stop block 54, that is, the limiting pin 41 can be abutted to the stop block 54 while being separated from the inner wall of the notch 11.

The locking mechanism 4 is symmetrically arranged at two ends of the first shaft 23, as shown in fig. 8, the limiting pins 41 are symmetrically arranged at two ends of the first shaft 23, the two ends of the first shaft 23 are provided with limiting holes 231 for limiting the limiting pins 41 and guide grooves communicated with the limiting holes 231, when the second connecting block 22 is locked, the limiting pins 41 respectively extend outwards from the two ends of the first shaft 23 and are inserted into corresponding insertion holes 13, so that the two ends of the first shaft 23 can be limited by the limiting pins 41, and the first shaft 23 is more stably limited in position, namely, the locking effect of the second connecting block 22 is improved.

Preferably, the elastic element 42 is an ejector spring, one end of the ejector spring is fixed on the inner wall of the first shaft 23, the other end of the ejector spring is fixedly connected with one end of the limiting pin 41, the outer diameter of the ejector spring is smaller than the diameter of the limiting hole 231, friction can not occur between the ejector spring and the inner wall of the first shaft 23 in the deformation process of the ejector spring, the situation that the ejector spring is blocked due to radial deformation in the deformation process of the ejector spring is prevented, and the retraction of the limiting pin 41 into the first shaft 23 or the outward extension of the first shaft 23 is influenced, so that the locking mechanism 4 can stably play a role.

In still another embodiment provided by the invention, a third connecting block 31 is installed at one end of the second connecting block 22 far away from the first connecting block 21, as shown in fig. 6, the second connecting block 22 is rotationally connected with the third connecting block 31 through a connecting shaft 221, the third connecting block 31 is rotationally connected with the second member 3 through a third shaft 311, as shown in fig. 1, the rotation axis of the third connecting block 31 on the second member 3 is perpendicular to the rotation axis of the second connecting block 22 on the third connecting block 31, the third shaft 311 is arranged along the length direction of the second member 3, that is, the vertical direction shown in fig. 1, the arrangement direction of the connecting shaft 221 is along the width direction of the second member 3, that is, the horizontal direction shown in fig. 1, a through groove is formed in the position of the second member 3 corresponding to the third connecting block 31, and the width of the third connecting block 31 is smaller than or equal to the thickness of the second member 3, so that the third connecting block 31 can be hidden on the second member 3, and the side surface of the second member 3 can be kept flat;

One of the degrees of freedom is that the second member 3 rotates about the rotation axis of the connection shaft 221, that is, the angle between the long sides of the first member 1 and the second member 3 can be adjusted; another degree of freedom is that the second member 3 rotates about the axis of rotation of the third shaft 311, i.e. the angle between the short sides of the first member 1 and the second member 3 can be adjusted.

During implementation, a locking structure can be arranged on the second member 3 and used for limiting the rotation of the third shaft 311, after the second member 3 rotates by taking the central axis of the third shaft 311 as the axis, the third shaft 311 is locked through the locking structure, so that the relative angle between the second member 3 and the third connecting block 31 is prevented from being changed, and the relative angle between the first member 1 and the second member 3 is difficult to maintain, wherein the locking structure is in the prior art and can be specifically matched with a pressing sheet by adopting a bolt and pushing the pressing sheet to lock the third shaft 311 through the bolt, and the specific setting position is selected according to actual conditions and is not repeated.

The embodiment further expands the range of the angle adjustment of the first component 1 and the second component 3, so that the connection mode of the first component 1 and the second component 3 is diversified to adapt to more installation requirements in the building process.
