The two movable plates respectively drive the two adjustment plates to approach each other along the sliding rod, and cooperate with the connecting rod to perform plug-in activities along the connecting block. The two adjustment plates push the support plate away from the fixed frame through the connecting plate, so that the support plate is in contact with the inner wall of the foundation pit for support.

[0008] Preferably, a servo motor is installed on the top of the fixing frame, and the output shaft of the servo motor is connected and fixed to the top end of the bidirectional screw rod.

[0009] The output shaft of the servo motor drives the bidirectional screw to rotate, and the rotating bidirectional screw drives the two screw-connected movable plates to move closer to or away from each other.

[0013] The spring rod is plugged into the adjusting plate, so that the movable plate is connected to the adjusting plate, and the movable plate drives the adjusting plate to move up and down.

[0014] Preferably, symmetrically distributed mounting holes are provided at the four corners of the top of the bottom plate, and fixing rods are fixed to both ends of the bottom of the fixing frame, and the fixing rods are plug-fitted into the mounting holes.

[0015] The fixing frame is plugged into the top of the base plate through a fixing rod, which makes it easy to replace support mechanisms of different specifications on the top of the base plate and can be suitable for foundation pits of different specifications.

[0016] Preferably, a rectangularly distributed fixing block is provided on an outer wall of one side of the support plate, and the fixing block is rotatably connected to the connecting plate, and the connecting rod and the connecting block form a plug-in fit.

[0017] The connecting rod is connected along the connecting block. As the two movable plates move relative to each other, the two movable plates drive the supporting plates to move through the adjusting plates and the connecting plates, so that the supporting plates are in contact with the inner wall of the foundation pit for support.

[0018] The beneficial effects of the utility model are:

[0019] By placing the base plate at the bottom of the foundation pit, the servo motor drives the bidirectional screw to rotate, so that the two movable plates are close to each other, and the two movable plates respectively drive the two adjustment plates to approach each other along the sliding rod, and cooperate with the connecting rod to perform plug-in activities along the connecting block. The two adjustment plates push the support plate away from the fixed frame through the connecting plate, so that the support plate is abutted against the inner wall of the foundation pit for support, which effectively solves the problem that the installation method in the existing technology mostly adopts welding reinforcement, which requires a long time and causes low working efficiency.
