Working principle:

when installing and placing cables, firstly, the first cable is slid into the lowest end of the first sliding groove from the opening of the upper end of the first sliding groove 3, then a partition plate 51 with a T-shaped groove 54 is slid into the second sliding groove 4 at the lowest end, then one clamping component 55 is lifted, the end cover 5512 is unscrewed, then the round rod 559 is pressed inwards to enable the round rod 559 to slide inwards, so that the round rod 559 pulls the pull rope 5511 to gradually enter the second accommodating groove 5510 for pinching, the pull rope 5511 pulls the clamping plate 553 into the first accommodating groove 552, when the clamping plate 553 is completely positioned in the first accommodating groove 552, the vertical end of the T-shaped block 551 is gradually inserted into the rectangular notch 53, the vertical end of the T-shaped block 551 is further inserted into the T-shaped groove 54, when the clamping plate 553 is positioned at the corner of the T-shaped groove 54, due to the increase of the space, the limiting contact of the round rod 559 is further pressed inwards, so that the first spring 555 resets the clamping plate 553 to rotate out of the first accommodating groove 552, thus, the clamping plate 553 is clamped in the T-shaped groove 54, and in the process that the T-shaped block 551 stretches into the T-shaped groove 54, the movable plate 556 contacts with the side face of the H-shaped support column 2 and compresses the movable plate 556, so that the partition plate 51 is stabilized in the second chute 4 through the clamping plate 553 clamped in the T-shaped groove 54 and the compression spring of the movable plate 556, finally, the end cover 5512 is screwed on, the first cable is limited, other cables are installed in the same way again, the cables are separated through the partition plate 51, when the last cable slides into the first chute 3, the partition plate 51 is placed in the second chute 4 at the uppermost end through the partition plate 51 without the T-shaped groove 54, and then the partition plate 51 is fixed on the H-shaped support column 2 through the bolts 52, so that the first chute 3 is sealed and the uppermost cable is limited and isolated.

When the H-shaped support column 2 or the partition assembly needs to be replaced and maintained, firstly, the end cover 5512 is unscrewed, then the round rod 559 is pressed, so that the round rod 559 moves towards the cylindrical notch 558, the pull rope 5511 is pulled, the pull rope 5511 pulls the clamping plate 553 back into the first accommodating groove 552, when the clamping plate 553 completely enters the first accommodating groove 552, the clamping plate 553 and the T-shaped groove 54 are in a clamping state, the spring II 557 resets the movable plate 556, so that the T-shaped block 551 moves out of the T-shaped groove 54 by a certain distance, at this time, the clamping plate 553 can be limited by two side surfaces of the vertical notch of the T-shaped groove 54 and cannot be unfolded, further, the clamping assembly 55 can be directly and easily taken out completely, after the clamping assembly 55 is taken out, all the partition plates 51 with the clamping assembly 55 can be taken down easily, finally, after the uppermost partition plates 51 are taken down by unscrewing the bolts 52, the partition assemblies 5 can be partially or completely replaced and maintained, and the bolts connected between the connection base 1 and the fixing base are replaced, and the H-shaped support column 2 can be replaced and maintained.
