Through the arrangement of the first marble groove 501, the marble 502, the marble spring 503, the second marble groove 504, the sliding groove 505, the sliding plate 506, the baffle plate 507, the lifting plate 508, the rubber plug 509 and the rubber plug hole 510, when in use, when the inner shell 2 is pushed into the outer shell 4, the marble Under the action of the ball spring 503, part of the ball 502 protrudes from the first ball groove 501. As the inner shell 2 is inserted, the ball 502 contacts the outer surface of the inner shell 2 and is gradually squeezed, and the ball spring 503 is compressed. When the inner shell 2 is pushed to a suitable position, the ball 502 is aligned with the second ball groove 504 on the inner shell 2. At this time, the ball spring 503 releases its elastic force and bounces the ball 502 into the second ball groove 504, thereby realizing the connection between the inner shell 2 and the outer shell 4. When the ball 502 needs to be replaced, first pull up the lifting plate 508 to separate the rubber plug 509 from the rubber plug hole 510. , and then continue to lift the lifting plate 508 to drive the baffle 507 to rise. Since the baffle 507 can block the marble spring 503 and the marble 502, when the baffle 507 rises to a certain height, the marble 502 and the marble spring 503 will be exposed. At this time, the damaged or replaced marble 502 can be easily removed from the first marble groove 501, and a new marble 502 can be installed.

[0031] Furthermore, the outer size of the rubber plug 509 is consistent with the inner size of the rubber plug hole 510, and multiple groups of rubber plugs 509 are arranged on the lower surface of the lifting plate 508. Through the arrangement of the rubber plugs 509 and the rubber plug holes 510, when in use, when the lifting plate 508 is lifted upward to start the disassembly process, multiple groups of rubber plugs 509 are pulled out from the rubber plug holes 510 at the same time, and the lifting resistance shared by each rubber plug 509 is relatively balanced, making the lifting action more stable and smooth, avoiding deformation of the lifting plate 508 or difficulty in lifting due to excessive force at a single point, and making the disassembly operation smoother.

A moving plate 609 is fixedly connected to the upper surface of the moving block 608. A limiting block 610 is fixedly connected to one side surface of the moving plate 609. A limiting groove 611 is provided on the inner surface of the first installation groove 601. A limiting rod 612 is slidably connected to the inner surface of the moving plate 609. A fixed plate 613 is fixedly connected to one end surface of the limiting rod 612. A limiting block 614 is fixedly connected to one side surface of the fixed plate 613.

The arrangement of the limiting column groove 617, the limiting column 618, the telescopic column 619, the spring 620 and the limiting baffle 621. When in use, the first installation groove 601 and the second installation groove 602 are respectively arranged on the upper surface of the outer shell 4 and the upper surface of the inner shell 2, providing a spatial basis for the installation and matching of related components. First, align the block 604 on the lower surface of the partition 605 with the block groove 603, insert the partition 605 in the middle of the inner shell 2 and fix it, and then install the sliding block 606 on the partition 605. The sliding block 606 slides on the upper surface of the partition 605, so that the sliding block 606 can slide above the partition 605, so that the subsequent movement of the sliding block 606 can drive the movement of other related components to realize the functions of limiting, etc.When the limit baffle 621 needs to be moved, the moving plate 609 is moved toward the fixed plate 613, the moving block 608 slides stably in the moving groove 607, and then the sliding block 606 is moved. When the appropriate position is reached, the moving plate 609 is released, and the spring 620 releases the elastic potential energy to push the moving plate 609, so that the limit block 610 fixedly connected to the moving plate 609 is bounced into the limit groove 611, thereby fixing the position of the limit baffle 621. When the spring 620 is extended and retracted, the limit column 618 slides in the limit column groove 617, and the limit column 618 drives the telescopic column 619 to move.

[0033] Furthermore, the inner dimension of the block groove 603 matches the outer dimension of the block 604, and multiple groups of blocks 604 are arranged at equal intervals on the inner surface of the inner shell 2. Since the inner dimension of the block groove 603 matches the outer dimension of the block 604, the block groove 603 limits the block 604, so that the position of the partition 605 is stable.

[0034] Furthermore, the inner dimension of the movable groove 607 is consistent with the outer dimension of the movable block 608, and multiple groups of limiting grooves 611 are evenly spaced on the inner surface of the first installation groove 601. Through the setting of the limiting grooves 611, when in use, multiple groups of equally spaced limiting grooves 611 provide different limiting position options, making the limiting mechanism 6 more flexible and applicable.

[0035] Furthermore, the inner dimension of the limit groove 611 is consistent with the outer dimension of the limit block 610, and multiple groups of limit rods 612 are arranged on the side surface of the fixed plate 613.

[0036] Furthermore, the outer dimension of the limiting block 614 is consistent with the inner dimension of the limiting groove 615, one end of the spring 620 is fixedly connected to the movable plate 609, and the movable plate 609 forms a telescopic structure through the spring 620 and the fixed plate 613. Through the setting of the limiting block 614 and the limiting groove 615, when in use, the limiting block 614 slides in the limiting groove 615, further constraining the movement range and direction of the fixed plate 613 and the components connected thereto from the side, thereby enhancing the stability and accuracy of the movement of the entire mechanism.

[0037] Furthermore, the fixed plate 613 is fixedly connected to the sliding block 606, and multiple groups of limit baffles 621 are arranged on the front and back surfaces of the sliding block 606. The inner size of the limit column groove 617 is consistent with the outer size of the limit column 618. Through the setting of the limit column groove 617 and the limit column 618, when in use, the limit column 618 slides in the limit column groove 617, which effectively prevents the movable plate 609 from twisting or excessively deforming when subjected to force, thereby ensuring the reliability and durability of the entire limit mechanism 6.

[0038] Working principle: The metal sheet 3 has a high-strength scratch-resistant and highly conductive coating for electrical conduction. When installation is required, the inner shell 2 is pushed into the outer shell 4. Under the action of the marble spring 503, part of the sphere of the marble 502 protrudes from the first marble groove 501. As the inner shell 2 is inserted, the marble 502 contacts the outer surface of the inner shell 2 and is gradually squeezed, and the marble spring 503 is compressed. When the inner shell 2 is pushed to the appropriate position, the marble 502 is aligned with the second marble groove 504 on the inner shell 2. At this time, the marble spring 503 releases its elastic force and bounces the marble 502 into the second marble groove 504, thereby realizing the connection between the inner shell 2 and the outer shell 4. When the marble 502 needs to be replaced, first pull it upwards. The lifting plate 508 causes the rubber plug 509 to disengage from the rubber plug hole 510, and then continues to lift the lifting plate 508 to drive the baffle plate 507 to rise. Since the baffle plate 507 can block the marble spring 503 and the marble 502, when the baffle plate 507 rises to a certain height, the marble 502 and the marble spring 503 will be exposed. At this time, the damaged or replaced marble 502 can be easily removed from the first marble groove 501, and a new marble 502 can be installed. After the installation is completed, the baffle plate 507 is lowered to return the sliding plate 506 to its initial position, and then the rubber plug 509 is inserted into the rubber plug hole 510 to restore the initial state of the mechanism for subsequent connection and disassembly operations. The first installation groove 601 and the second installation groove 606 are connected. The grooves 602 are respectively provided on the upper surface of the outer shell 4 and the upper surface of the inner shell 2, providing a spatial basis for the installation and matching of related components. First, the block 604 on the lower surface of the partition 605 is aligned with the block groove 603, and the partition 605 is inserted in the middle of the inner shell 2 and fixed. Then, the sliding block 606 is installed on the partition 605, and the sliding block 606 slides on the upper surface of the partition 605, so that the sliding block 606 can slide above the partition 605, so that the subsequent movement of the sliding block 606 can drive the movement of other related components to realize the functions of limiting. When it is necessary to move the limit baffle 621, the moving plate 609 is moved toward the fixed plate 613, and the moving block 608 is in the moving groove. 607, and then move the sliding block 606. When the moving plate 609 is reached, the spring 620 releases its elastic potential energy to push the moving plate 609, so that the limit block 610 fixedly connected to the moving plate 609 pops into the limit groove 611, thereby fixing the position of the limit baffle 621. When the spring 620 is extended or retracted, the limit column 618 slides in the limit column groove 617, and the limit column 618 drives the telescopic column 619 to move. The telescopic column 619 is fixedly connected to the moving plate 609, so that it moves more stably when the spring 620 releases its performance. By adjusting the position of the limit baffle 621, micro display screens of different sizes can be docked, thereby improving flexibility and applicability.
