[0032] Please refer to Figures 5 to 9 The rotating mechanism 6 includes a first slide groove 601, the first slide groove 601 is opened at the top of the rotating disk 501, the top of the mounting seat 1 is located at one end of the rotating disk 501 and is provided with a second slide groove 602, the inner walls of the first slide groove 601 and the second slide groove 602 are symmetrically provided with limiting grooves 7 on both sides, and the outer walls of the positioning seat 511 are symmetrically fixedly connected with limiting blocks 8 on both sides, the bottom end of the inner wall of the first slide groove 601 is fixedly connected with a first tooth plate 603, the bottom end of the inner wall of the second slide groove 602 is fixedly connected with a second tooth plate 604, the bottom end of the inner wall of the second slide groove 602 is located on one side of the second tooth plate 604 and is fixedly connected with a horizontal plate 605, and the upper surface of the horizontal plate 605 facing the rotating disk 501 is provided with a guide inclined surface. One end of the positioning seat 511 is rotatably connected to a rotating plate 606, and the interior of the positioning seat 511 is slidably connected to a push rod 607 extending to the outer wall of the positioning seat 511. The interior of the positioning seat 511 is located on the outer wall of the push rod 607 and is rotatably connected to a third spur gear 608. The interior of the positioning seat 511 is located on the outer wall of the third spur gear 608 and is slidably connected to a push rod 609. A third motor 610 is installed inside the positioning seat 511, and the output end of the third motor 610 is connected to a fourth spur gear 611. The push rod 609 and the fourth spur gear 611 both extend to the bottom of the positioning seat 511. After the vertical rod 505 rotates to a horizontal shape, a reinforcement operation is performed through the reinforcement mechanism 9.

[0033] In this embodiment: when the laser gas detection probe 4 is not in use, the first motor 502 is started to drive the rotating disk 501 to rotate, so that the first slide groove 601 is aligned with the second slide groove 602. At this time, the first tooth plate 603 is aligned with the second tooth plate 604. At this time, the third motor 610 can be started, and the third motor 610 drives the fourth spur gear 611 to rotate. The fourth spur gear 611 rotates to move along the first tooth plate 603 and the second tooth plate 604, and then drives the positioning seat 511 to slide in the first slide groove 601 and the second slide groove 602. At this time, the limit block 8 slides in the limit slot 7, and the positioning seat 511 The displacement of the push rod 607 is driven by the third spur gear 608 to rotate, and the third spur gear 608 is driven by the push rod 607 to displace, and the push rod 607 is driven to displace and the rotating plate 606 is driven to rotate. The rotating plate 606 rotates in an inclined shape and the bottom end does not move out of the second slide groove 602.

[0034] When the vertical rod 505 needs to be rotated, the positioning seat 511 moves toward the vertical rod 505, and the rotating plate 606 first contacts the vertical rod 505, pushing the vertical rod 505 to rotate. When the positioning seat 511 moves into the first slide groove 601, the top rod 609 separates from the horizontal plate 605, and the rotating plate 606 can be rotated downward at this time until the positioning seat 511 and the rotating plate 606 press the vertical rod 505 against the fixed plate 510, so that the vertical rod 505 remains in a vertical state, which is convenient for rotating the vertical rod 505. Therefore, when the laser gas detection probe 4 is not in use, the vertical rod 505 can be rotated and stored to prevent the vertical rod 505 from being too high and affecting the movement of the vehicle body.

[0035] In order to enable the rotating plate 606 to smoothly lift the end of the vertical rod 505 in a horizontal state, an arc-shaped surface is provided at the free end of the rotating plate 606. When the vertical rod 505 is in a horizontal state, the lower bottom surface of its end contacts the free end of the rotating plate 606. At this time, the rotating plate 606 in an inclined state can gradually lift the end of the vertical rod 505 as the positioning seat 511 moves.

The top of the rotating shaft 905 passes through the mounting seat 1 upward and is fixedly connected to a positioning plate 906.

[0037] In this embodiment: when the vertical rod 505 is in a horizontal state, the positioning seat 511 continues to move away from the vertical rod 505, and the positioning seat 511 moves and contacts the extrusion block 901, pushing the extrusion block 901 to move, and the displacement of the extrusion block 901 drives the displacement frame 902 to move, causing extrusion on the spring 903, and the displacement of the displacement frame 902 drives the fifth spur gear 904 to rotate, and the rotation of the fifth spur gear 904 drives the rotation shaft 905 to rotate, and the rotation of the rotation shaft 905 drives the positioning plate 906 to rotate, and the positioning plate 906 rotates so that one end of the positioning plate 906 contacts the upper top surface of the vertical rod 505 in a horizontal state, fixing the vertical rod 505 inside the top end of the mounting seat 1, thereby preventing the vertical rod 505 from being firmly fixed and shaking during the movement of the vehicle body, and preventing the laser gas detection probe 4 from being damaged by the vibration of the vehicle body.
