[0024] Working principle: First, the staff installs the foundation pit support plate 1 inside the foundation pit to protect the foundation pit. Then, when the staff uses tools to move multiple support frames 2 to the inside of the foundation pit support plate 1, the staff rotates the sleeve 8 to a vertical state through the manual rod 10 in cooperation with the connecting plate 6 and the rotating shaft 7. Then, the sleeve 8 can be rotated by the manual rod 10 in cooperation with the turntable 53 and the fixed plate 52, so that the threaded rod 9 can drive the card plate 12 to move toward the fixed shell 131 through the bearing seat 11, so that the card plate 12 moves to the inside of the second sliding groove 132, and The slider 51 moves inside the first sliding groove 3 to the top of the first card slot 4. Under the action of gravity, the slider 51 can move downward, so that the slider 51 is tightly fitted with the inner cavity of the first card slot 4. Then the staff drives the sleeve 8 to rotate in the opposite direction through the manual rod 10, so that the threaded rod 9 drives the card plate 12 to move upward through the bearing seat 11, so that the card plate 12 is tightly fitted with the inner cavity of the second card slot 133, thereby enhancing the fixing effect between the two support frames 2. Then the staff can install multiple support frames 2 inside the foundation pit support plate 1 through the mounting plate 14.
