at least four elastic ropes 807, one ends of which are fixedly arranged on the supporting rod, and the other ends of which are fixedly arranged at preset positions on the upper surface and the lower surface of the first card and the second card. The working principle of the base and the top cover are that: when the top cover is clamped to the base, the card arranged in the second through hole of the top cover is blocked by the baffle arranged in the first through hole of the base, the elastic rope is compressed under the action of elasticity, the elastic rope arranged on the upper surface of the card is stretched immediately, and meanwhile, the card is arranged on the supporting rod through the clamping ring, and the two cards can rotate upwards by a certain angle along the supporting rod at the moment, so that the distance between the two cards is compressed, the card can smoothly pass through a gap between the two baffles, and once the card passes through the gap, the elastic rope is restored to be the original state, so that the card is clamped on the other side of the baffle. Similarly, when the base and the top cover are required to be disassembled, the top cover and the base are forced in two opposite directions, when the card meets the blocking of the baffle, the elastic rope arranged on the upper surface of the card is stretched, the elastic rope positioned on the lower surface of the card is compressed, and the distance between the two cards is also compressed, so that the card can pass through the gap between the two baffles, and the separation of the base and the top cover is completed. The scheme has the advantages of good fixing stability, high dismounting efficiency and simple structure. And this is merely illustrative of a preferred embodiment and is not limited thereto. In practicing the present invention, appropriate substitutions and/or modifications may be made according to the needs of the user.
In another example, the base further comprises:
a first concave portion 9 having a rectangular structure, the first concave portion being divided into a first concave portion and a second concave portion by a cylindrical wire column 10, and a wire insertion terminal for electrical connection or communication connection being provided in a rectangular accommodating chamber formed by the first concave portion and the fourth concave portion;

The scheme has the advantage of good implementation effect. And this is merely illustrative of a preferred embodiment and is not limited thereto. In practicing the present invention, appropriate substitutions and/or modifications may be made according to the needs of the user.
In another example, the first and second cards have lengths of 1/3 of the diameter of the first through hole. The main purpose of setting like this is to avoid the length of first card and second card too long, causes first card and second card under the elasticity effect of elasticity rope, can not follow the clearance passageway between two baffles and pass through, makes the unable normal work of elastic component. The scheme has the advantages of ensuring the normal operation of the elastic element and having good implementation effect. And this is merely illustrative of a preferred embodiment and is not limited thereto. In practicing the present invention, appropriate substitutions and/or modifications may be made according to the needs of the user.
In another example, the number of the first through holes and the second through holes is set to 4, and the first through holes are located at the corner positions of the base, and the second through holes are located at the corner positions of the top cover. Through holes arranged at the four corner positions, namely the mounting positions of the elastic clamping pieces, so that the base and the top cover have four-angle mounting and fastening effects. And this is merely illustrative of a preferred embodiment and is not limited thereto. In practicing the present invention, appropriate substitutions and/or modifications may be made according to the needs of the user.
In another example, the elastic clamping piece and the baffle are installed in another mode:
four baffles are uniformly distributed in the same plane along the inner wall of the first through hole, so that any baffle is perpendicular to the connecting line between two adjacent baffles.
