After the preliminary installation of the upper installation cover plate (8), the linkage driving long rod (22) is pressed with a finger, and the linkage driving long rod (22) is engaged. The long rod (18) is driven downward by the pressing force, and the long rod (18) is driven downward by the inner movable slide rod (13) through the second connecting spring (19), so that the clamping cylinder (14) enters the interior of the through-groove (27), and the limiting clamping protrusion (17) enters the protrusion limiting groove (29) through the protrusion avoiding groove (28), and then the clamping cylinder (14) is rotated by the rotating driving column (16), so that the limiting clamping protrusion (17) and the protrusion avoiding groove (28) are misaligned. At this time, the first connecting spring (15) is in a stretched state, and the clamping cylinder (14) cannot be automatically reset, so that the upper mounting cover plate (8) is tightened and fits on the bus duct body (1); 2) During disassembly, the rotating driving column (16) is used to rotate the clamping cylinder (14) so ​​that the limiting clamping protrusion (17) is aligned with the protrusion avoidance groove (28), and then the rotating driving column (16) is released, and the clamping cylinder (14) is automatically reset through the reset action of the first connecting spring (15), and the entire upper mounting cover (8) is removed from the bus duct body (1).
