[0031] Since round plate 11 is movably sleeved in the inner surface of limiting column 10 and the inner surface of the top of limiting column 10 and the outer surface of long rod 9 are movably sleeved, when upper support sliding plate 2 is subjected to upward tension, it will make upper support sliding plate 2 move with long rod 9 through sliding block 8, at this time, round plate 11 will move along the inner surface of limiting column 10 under the driving of long rod 9, when round plate 11 moves to the top inside limiting column 10, it will be blocked by limiting column 10, so that round plate 11 cannot continue to move upward, thereby limiting the movement of upper support sliding plate 2 through long rod 9 and sliding block 8, so as to prevent falling off, thereby realizing anti-off function.

[0032] Among them, the top inside limiting column 10 is movably sleeved with baffle 12, the inner surface of baffle 12 and the outer surface of long rod 9 are movably sleeved, the bottom of baffle 12 is fixedly installed with spring 13, the other end of spring 13 and the top of round plate 11 are fixedly connected.

[0035] The inner surface of limiting groove 14 and the outer surface of limiting block 15 are smooth, so as to ensure that limiting block 15 does not jam when moving along the inside of limiting groove 14.

[0037] When the bottom end of the inclined rod 17 moves, a pulling force is generated on the cover plate 16 by the inclined rod 17, so that the cover plate 16 moves together with the baffle 12 through the limiting block 15.

[0038] The bottom end of the inclined rod 17 is hingedly connected with a rectangular block 18, the outer surface of the rectangular block 18 is movably sleeved with the inner surface of the top end of the lower support slide plate 1, the outer surface of the rectangular block 18 is movably sleeved with a limiting frame 19, and the outer surface of the limiting frame 19 is fixedly sleeved with the inner surface of the top end of the lower support slide plate 1.

[0040] The inside of the limiting frame 19 is movably sleeved with an elongated threaded rod 20, the right side of the outer surface of the elongated threaded rod 20 is threadedly sleeved with the inner surface of the rectangular block 18, the left side of the outer surface of the elongated threaded rod 20 is movably sleeved with a U-shaped frame 21, and the outer surface of the U-shaped frame 21 is fixedly sleeved with the inner surface of the top end of the lower support slide plate 1.

[0041] When the elongated threaded rod 20 rotates, the rectangular block 18 will move under the action of the elongated threaded rod 20 because the elongated threaded rod 20 and the rectangular block 18 are threadedly sleeved.

[0042] The front end of the outer surface of the elongated threaded rod 20 is fixedly sleeved with a circular wheel 22, the rear end of the circular wheel 22 is movably connected with the front end of the U-shaped frame 21, and the number of the circular wheels 22 is two.

[0043] When the circular wheel 22 rotates, the elongated threaded rod 20 rotates together, and the two circular wheels 22 are drivingly connected through a transmission belt 23, so that the operator only needs to rotate one of the circular wheels 22 to make the two circular wheels 22 rotate synchronously.

[0044] The bottom of the outer surface of each of the two circular wheels 22 is movably connected with a clamping rod 24, the number of the clamping rods 24 is two, the opposite surfaces of the two clamping rods 24 are fixedly provided with a connecting plate 25, and the top end of the connecting plate 25 is movably connected with the bottom end of the U-shaped frame 21.

[0048] The middle end of the horizontal rod 27 is movably sleeved with a short threaded rod 28, the top end of the short threaded rod 28 penetrates through the connecting plate 25 and the U-shaped frame 21 and extends to the top end of the U-shaped frame 21 and is fixedly sleeved with a handle 29, the bottom end of the handle 29 is movably connected with the top end of the U-shaped frame 21, the outer surface of the short threaded rod 28 is threadedly sleeved with the inner surface of the connecting plate 25, and the outer surface of the short threaded rod 28 is movably sleeved with the inner surface of the U-shaped frame 21.

[0049] When the handle 29 is rotated, the short threaded rod 28 will rotate along the inner surface of the U-shaped frame 21, so that the connecting plate 25 threadedly sleeved with the outer surface of the short threaded rod 28 moves along the outer surface of the vertical rod 26.

[0050] The working principle and use process of the utility model:

[0051] When the spherical support is subjected to upward tension, the upper support sliding plate 2 will move upward along with the long rod 9 through the sliding block 8, at this time, the circular plate 11 fixedly connected with the long rod 9 will move along with the inner surface of the limiting column 10 and compress the spring 13, when the circular plate 11 moves to the top inside the limiting column 10 and cannot continue to move, the long rod 9, the sliding block 8 and the upper support sliding plate 2 will stop moving upward, and under the restoring action of the spring 13, when the upper support sliding plate 2 is no longer subjected to upward tension, the upper support sliding plate 2, the sliding block 8, the long rod 9 and the circular plate 11 will restore to the original position, thereby preventing falling, thereby realizing the anti-falling function.

[0052] When the distance of the upper support sliding plate 2 needs to be adjusted, the operator rotates the handle 29, so that the short threaded rod 28 rotates, and the connecting plate 25 threaded on the outer surface of the short threaded rod 28 moves along the outer surface of the vertical rod 26 with the clamping rod 24, until the clamping rod 24 is separated from the tooth groove on the outer surface of the circular wheel 22, the locking of the clamping rod 24 on the circular wheel 22 is released, then the operator rotates the circular wheel 22, so that the two circular wheels 22 rotate synchronously with the long threaded rod 20 under the drive of the transmission belt 23, at this time, the rectangular block 18 threaded on the long threaded rod 20 will move along the inner surface of the limiting frame 19 with one end of the inclined rod 17, so that the other end of the inclined rod 17 generates a pulling force on the cover plate 16, pulls the cover plate 16 to move the baffle 12 towards the circular plate 11 through the limiting block 15, so as to adjust the distance between the baffle 12 and the circular plate 11, thereby adjusting the distance of the upper support sliding plate 2, improving the convenience of use.

[0053] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
