[0062] The partition structure 11 has a certain length as the boundary line, and can be curvedly extended or linearly extended, which is not limited in particular, as long as the avoiding space 12 is formed near the corner side of the first support 1. The avoiding structure formed by the combination of the adjacent partition structures 11 has the longer partition structure 11 and the larger avoiding space 12.

The connecting seat 73 comprises a base and an external threaded section connected with each other, the base is provided with a threaded hole, and the connecting seat 73 is boltedly connected with the other one of the two adjacent display screen supports. When the locking rod 71 extends into the locking hole 621 and is locked and connected with the clamping hole 631, the first spring 74 is compressed to accumulate elastic potential energy, and when the locking rod 71 is unlocked from the clamping hole 631, the first spring 74 releases the accumulated elastic potential energy to reset the locking rod 71. The screw handle 75 is rotated to control the movement of the screw handle 75 away from the connecting seat 73, the end of the locking rod 71 is tightly pressed by the screw handle 75, the locking rod 71 is more tightly clamped with the clamping hole 631, the locking rod 71 is prevented from loosening, and the connection is more firm.

The groove housing 6121 and the sub-housing 6122 are bolted, the wall structure of the sub-housing 6122 is assembled in the groove housing 6121, and the wall structure of the sub-housing 6122 is relatively spaced apart from the bottom of the groove housing 6121 to form the sliding groove 613; the sliding piece 62 moves in or out from the right opening of the groove housing 6121 in the sliding stage relative to the housing 612.

[0075] The bottom of the groove housing 6121 is provided with a long strip-shaped adjustment hole 614, and the upper edge and the lower edge of the adjustment hole 614 are provided with the positioning tooth 611. Part of the adjustment piece 64 is located outside the housing 612, and the other part of the adjustment piece 64 is connected with the sliding piece 62 in the sliding groove 613 through the adjustment hole 614, so that the sliding piece 62 can be driven to move relative to the adjustment seat 61 outside the housing 612.

[0076] In some embodiments, the sliding member 62 comprises a connecting curved portion 622 and a locking portion 623; the curved portion 622 extends in an arc shape, at least part of the curved portion 622 is fitted in the sliding groove 613, and the curved portion 622 is connected with the adjusting member 64; the locking portion 623 is provided with a locking hole 621, and the locking portion 623 is provided with a slot 624 which is in communication with the outside; along the axial direction of the locking hole 621, the slot 624 is located between the two openings of the locking hole 621 and is in communication with the locking hole 621; part of the locking tongue 63 is inserted into the slot 624, and the clamping hole 631 of the locking tongue 63 is clamped into the slot 624 and is in communication with the locking hole 621.

[0077] More specifically, the curved portion 622 and the locking portion 623 of the sliding member 62 are connected at an angle, the curved portion 622 is matched with the sliding groove 613, and the adjusting member 64 is located on the convex side of the curved portion 622. The locking portion 623 is block-shaped, and the locking portion 623 is located outside the sliding groove 613. The locking hole 621 penetrates through the locking portion 623, and the locking hole 621 is opposite to the concave side of the curved portion 622.

[0078] In some embodiments, the sliding member 62 further comprises a resilient member 625 which is arranged in the slot 624 and abuts against the locking tongue 63; when the locking tongue 63 moves into the slot 624 to the unlocking position, the resilient member 625 is deformed to accumulate elastic potential energy; the resilient member 625 releases the accumulated elastic potential energy, and the locking tongue 63 moves out of the slot 624 to the locking position.

[0079] More specifically, no matter in the unlocking position or the locking position, the resilient member 625 is in a compressed state, and the difference is that the compression amount of the resilient member 625 is larger when the locking tongue 63 is in the unlocking position. Under the action of an external force, the locking tongue 63 moves into the slot 624, and the compression amount of the resilient member 625 increases; after the external force disappears, the resilient member 625 releases the accumulated elastic potential energy, and if the locking tongue 63 is in locking connection with the locking rod 71, the resilient member 625 provides the force for the clamping hole 631 to be clamped into the slot 624, and if the locking tongue 63 is separated from the locking rod 71, the locking tongue 63 moves out of the slot 624 to realize resetting.

[0082] More specifically, an end of the first plate 632 away from the second plate 633 is the front end of the first plate 632, and an end of the first plate 632 connected with the second plate 633 is the rear end of the first plate 632. The front end of the first plate 632 is inserted into the slot 624, and the second plate 633 is located outside the slot 624; the first plate 632 and the second plate 633 are connected at an angle, and the second plate 633 forms a pressing part which is easy to press. The elastic member 625 is always in a compressed state, and the elastic member 625 always provides a force for the lock tongue 63 to move out of the slot 624; by pressing the second plate 633, the first plate 632 is driven to move into the slot 624 to achieve unlocking.

[0083] The clamping hole 631 is formed along the thickness direction of the first plate 632, and the clamping hole 631 comprises a first curved edge and a second curved edge connected with each other, and both the first curved edge and the second curved edge are part of the edge of a circular hole.

The cam handle 644 rotates towards the unlocking direction, the second spring 643 releases the accumulated elastic potential energy, the insertion piece 641 moves away from the sliding piece 62, and the tooth portion 6414 and the positioning tooth 611 are separated.

[0088] In some embodiments, the side of the sliding piece 62 close to the adjusting hole 614 is provided with a mounting groove 626 recessed in a direction away from the adjusting hole 614. The side of the mounting groove 626 opposite to the adjusting hole 614 is provided with a mounting hole 627. The mounting hole 627 is in communication with the mounting groove 626. The connecting rod 642 penetrates the through hole 6413 and the mounting hole 627 to be inserted into the sliding piece 62.

[0089] More specifically, the insertion portion 6412 of the insertion piece 641 is matched with the mounting groove 626. The insertion portion 6412 of the insertion piece 641 is inserted into the mounting groove 626. By using the above scheme, the connecting rod 642 provides sufficient support for the rotation of the cam handle 644. In the stages of approaching or moving away from the adjusting seat 61, the connecting rod 642 can play the role of precise guidance.
