The fixing block 11 is installed inside the opening 7 later, the fixing hole 12 is oppositely distributed to the positioning hole, the positioning column 8 is installed inside the positioning hole and the fixing hole 12 at the same time, and the connection and fixation of the fixed seat 1 and the movable seat 2 are realized by the fixing block 11.

[0023] In this embodiment, a fixing hole 12 is opened on the fixing block 11, and the fixing hole 12 cooperates with the positioning column 8. A support plate 10 is movably installed on one side of the fixed seat 1 and the movable seat 2. The support assembly 5 includes a support tube 13, and a rotating shaft 20 is installed at the bottom of the support tube 13. The support tube 13 is installed inside the fixed frame 4 through the rotating shaft 20. A rotating column 14 is rotatably installed at one end of the support tube 13, and a fixed tube 15 is movably installed at one end of the rotating column 14. A threaded column 16 is fixed on the rotating column 14, and the threaded column 16 is respectively rotatably installed. It is installed inside the fixed tube 15 and the support tube 13, one end of the fixed tube 15 is welded with a connecting seat 17, a fixed ear 18 is movably installed on the connecting seat 17, and a fixed plate 19 is welded on the fixed ear 18. Through the rotation of the rotating column 14, the threaded column 16 rotates inside the support tube 13 and the fixed tube 15, and the overall length of the support assembly 5 is adjusted by rotation, and the fixed plate 19 is fixed in contact with the ground. The support assembly 5 is tilted to support the fixed seat 1 and the movable seat 2, and the fixed seat 1 and the movable seat 2 provide supporting force for the support plate 10 to achieve support for the inner wall of the foundation pit.

[0024] When the device is in use, the support plates 10 of different widths are rotated to contact the inner wall of the foundation pit according to the depth of the foundation pit. After the support plates 10 contact the inner wall of the foundation pit, they are rotated to use the fixed seat 1 and the movable seat 2. When the fixed seat 1 and the movable seat 2 need to be distributed in parallel, the support assembly 5 is tilted and opened from the inside of the fixed frame 4 through the rotating shaft 20. The rotating column 14 drives the threaded column 16 to rotate inside the fixed pipe 15 and the support pipe 13. The rotation increases the overall length of the fixed pipe 15 and the support pipe 13, and the fixed plate 19 is brought into contact with the ground. After contact, the fixed plate 19 is fixed. After the fixed plate 19 is fixed, the rotating column 14 is rotated again. The rotating column 14 and the threaded column 16 cooperate to provide supporting force for the fixed seat 1 and the movable seat 2. When the fixed seat 1 and the movable seat 2 are required to be in a straight line to support the deep foundation pit, the fixed plate 19 is fixed to the ground. The positioning column 8 is pulled out from the inside of the positioning hole and the fixing hole 12, and the fixing block 11 is taken out from the inside of the opening 7 after being pulled out. After being taken out, the positioning column 8 is installed in the inside of the positioning hole, and the fixed seat 1 and the movable seat 2 are distributed in a straight line up and down. The positioning column 8 provides preliminary support and fixation for the fixed seat 1 and the movable seat 2, and the support assembly 5 drives the fixing frame 4 to move downward. One end of the fixing frame 4 enters into the inside of the limiting groove 6, and the fixed seat 1 and the movable seat 2 are fixed for the second time. The length of the support assembly 5 is adjusted again, and the movable seat 2 and the fixed seat 1 are supported and fixed by the support assembly 5. A rubber plate is fixed on the inner wall of the fixing frame 4. The rubber plate generates friction with the inner walls of the fixing groove 3 and the limiting groove 6 under thrust, and the friction force limits and fixes the position of the fixing frame 4, thereby completing the support of the fixed seat 1 and the movable seat 2 through the fixing frame 4.
