[0039] Those skilled in the art can understand that the top of the tension spring 423 is connected to the first question mark hook 421 fixed to the bottom of the vertical slider 412, and the bottom of the tension spring 423 is connected to the second question mark hook 422 fixed to the top surface of the base 11. The tension spring 423 can be fixed between the vertical slider 412 and the base 11 by the first question mark hook 421 and the second question mark hook 422, so that when the vertical slider 412 moves upward or downward relative to the base 11, the tension spring 423 is pulled or squeezed, and the vertical slider 412 is reset by the elastic force of the tension spring 423.

[0043] Those skilled in the art can understand that the two sliding components 2 are symmetrically arranged on both sides of the warning component 5, and the stability of the railing 3 when moving can be enhanced by the two sliding components 2.

[0045] This is because the second conductive member 52 fixed on the top of the base 11 and the first conductive member 51 fixed on the bottom of the railing 3 are arranged at intervals along the width direction of the base 11. When an unrelated person pushes or pulls the railing 3 along the width direction of the base 11 and from the second conductive member 52 to the first conductive member 51, the railing 3 moves toward the first conductive member 51 along the width direction of the base 11 under the action of the pushing or pulling force, so that the first conductive member 51 moves toward the second conductive member 52 along the width direction of the base 11. At this time, the first conductive member 51 contacts both ends of the second conductive member 52, so that a closed conductive loop is formed between one end of the second conductive member 52, the warning member 53, the other end of the second conductive member 52, and the second conductive member 52, which are connected in series by a wire, so that the warning member 53 sends an alarm to provide a warning prompt.

[0047] This is because, a limiting groove is provided on the moving block 511 fixed at the bottom of the railing 3, and the first conductive contact plate 512 is fixed at the top of the limiting groove, so that the first conductive contact plate 512 is fixed by the moving block 511, so that the first conductive contact plate 512 moves with the railing 3; the fixed block 521 is fixed to the top surface of the base 11, so that the warning member 53 is placed and the connecting block 522 is fixed by the fixed block 521; the connecting block 522 is fixed to a side of the fixed block 521 close to the moving block 511, and the connecting block 522 and the moving block 511 are arranged at intervals along the width direction of the base 11, and the size of the connecting block 522 is adapted to the size of the limiting groove, and the second conductive contact plate 523 and the third conductive contact plate 524 are symmetrically fixed at the top of the connecting block 522. When the railing 3 moves toward the first conductive member 51 along the width direction of the base 11 under the action of thrust or tension, the moving block 511 The first conductive touch plate 512 is driven to move toward the connecting block 522 along the width direction of the base 11. At this time, the connecting block 522 is located in the limiting groove, and the second conductive touch plate 523 and the third conductive touch plate 524 are respectively in contact with the two ends of the first conductive touch plate 512, so that a closed conductive loop is formed between the second conductive touch plate 523, the warning member 53, the third conductive touch plate 524 and the first conductive touch plate 512 which are connected in series by wires in sequence, so that the warning member 53 issues an alarm to provide a warning prompt; when the railing 3 is reset under the action of the reset component 4, the moving block 511 drives the first conductive touch plate 512 to move in a direction away from the connecting block 522. At this time, the connecting block 522 is moved out of the limiting groove, and the second conductive touch plate 523 and the third conductive touch plate 524 are separated from the first conductive touch plate 512, so that the formed closed conductive loop is disconnected, and then the warning member 53 automatically stops the warning.

[0048] In some possible implementations, the warning element 53 includes: an alarm 531; a power source 532, wherein the power source 532 and the alarm 531 are connected in series via a wire. The alarm 531 may be a buzzer.
