[0031] The adjusting assembly 32 comprises a fixed rod 33, the top of the fixed rod 33 is fixed with a limiting disc 34, a pressing screw rod 37 is rotatably installed between the limiting disc 34 and the fixed rod 33, one end of the pressing screw rod 37 is movably connected with the collection camera 30, a displacement tube 35 is movably installed on the side of the fixed rod 33, an adjusting screw rod 36 is rotatably installed in the displacement tube 35, the adjusting screw rod 36 is rotatably installed on the mounting seat 28, a positioning hole 39 is formed in the inside of the support tube 10, a positioning column 38 is movably installed in the inside of the positioning hole 39, one end of the positioning column 38 is fixed on the fixed tube 12, the adjusting screw rod 36 is selected in the displacement tube 35, the displacement tube 35 rotates to push the fixed rod 33 to move horizontally, the horizontal movement of the fixed rod 33 adjusts the position of the pressing point of the pressing screw rod 36 and the collection camera 30, and the collection camera 30 has different inclination angles at different pressing points.

[0032] Working principle: During use, the fixed base 1 and the support base 3 are fixedly installed on the inner wall of the subway tunnel. After the fixed base 1 and the support base 3 are fixed, the tilt angle of the support frame 5 is adjusted. The tilt angle of the support frame 5 is adjusted in conjunction with the existing bubble level. During adjustment, the screw 16 is rotated, which rotates on the crossbar 15. The rotating screw 16 pushes the rotating column 11 upward. After the rotating column 11 moves upward, the support tube 10 moves on the positioning column 38. As the rotating column 11 moves, it will rotate on the support tube 10. The rotating column 11 rotates the lower crossbar 15 synchronously on the fixed tube 12 to adjust the support angle of the adjusting screw 16. After the support tube 10 moves upward, the fixed shaft 9 drives the support frame 5 to rotate and tilt on the fixed plate 2. After the tilt angle of the support frame 5 is adjusted, the left and right angles of the acquisition camera 30 are adjusted. The rotating seat 7 is pushed upward by the threaded column 25. After the rotating seat 7 moves upward, the limiting column 17 separates from the inside of the limiting hole 27, and the rotating seat 7 loses the limiting force. The rotating seat 7 is rotated so that the limiting hole 27 at different positions cooperates with the limiting column 17 to limit the movement. When the installation environment is not suitable for upward installation of the acquisition component 8, the rotating seat 7 can be rotated upward to separate the limiting post 17 from the limiting hole 27, and the rotating seat 7 can be rotated to coincide with the opening between the rotating seat 7 and the arc-shaped seat 6. The limiting plate 20 drives the slider 21 to move. When the slider 21 moves to one end of the slide groove 18, the rotating seat 7 rotates on the slider 21 through the rotating shaft 22 on the limiting plate 20. The downward rotation of the limiting plate 20 causes the acquisition component 8 to move downward between the support tube 10 and the wall. The support tube 10, the rotating post 11, and the fixed post 13 cooperate to provide shielding protection for the acquisition component 8. To avoid damage caused by collisions between external objects and the acquisition component 8, when it is necessary to adjust the tilt angle of the acquisition camera 30, the adjusting screw 36 is selected in the displacement tube 35. After the displacement tube 35 rotates, it pushes the fixing rod 33 to move horizontally. The horizontal movement of the fixing rod 33 adjusts the position of the extrusion screw 36 and the extrusion point of the acquisition camera 30. The tilt angle of the acquisition camera 30 is different depending on the position of the extrusion point. The acquisition camera 30 is installed inside the slot 29 through a torsion spring shaft. One end of the acquisition camera 30 is always tilted upwards and in contact with the extrusion screw 36 for limiting and fixing.
