One end of the movable carrier bar 54 is fixedly provided with a matching upper moving column 56, which is inserted into the upper pushing bar frame 26, and the matching upper moving column 56 contacts the inner wall of the upper pushing bar frame 26.

[0056] like Figures 8 to 11 As shown, the device support assembly includes a connecting carrier block 6, a connecting connecting plate 7 and a second support plate 8. The connecting carrier block 6 is sleeved on the bearing support rod 45. A mounting through hole 61 is opened on the connecting carrier block 6. The mounting through hole 61 cooperates with the bearing support rod 45, and a first spring 62 is sleeved on the bearing support rod 45. A slope frame 63 is fixedly provided on one side of the connecting carrier block 6, and a bearing bar 64 is fixedly provided on the other side. A push-up carrier block 65 is fixedly provided on the bearing bar 64. In addition, the two ends of the first spring 62 are respectively fixed on the connecting carrier block 6 and the mounting movable plate 4.

[0057] like Figure 7 and Figure 9 As shown, a matching linkage hole 71 is provided on the connecting plate 7, and a supporting rod 34 is inserted into the matching linkage hole 71. A first supporting plate 72 is fixedly provided on the connecting plate 7, and a first supporting block 73 is fixedly provided at one end of the first supporting plate 72. A first connecting hole 74 is provided at the other end of the connecting plate 7, and a matching installation rod 47 for installing one side of the movable plate 4 is inserted into the first connecting hole 74.

[0058] like Figure 10 、 Figure 11 and Figure 12 As shown, the second support plate 8 is sleeved on the matching mounting rod 47 on the other side of the movable plate 4, and a second connecting bearing hole 81 is opened on the second support plate 8. The second connecting bearing hole 81 cooperates with the matching mounting rod 47, and a second spring 811 is sleeved on the matching mounting rod 47 on which the second support plate 8 is sleeved, and the two ends of the second spring 811 are respectively fixed on the rod end matching block 48 and the second support plate 8, the upper end of the second support plate 8 is fixedly provided with an inclined strip 82, and one end of the second support plate 8 is fixedly provided with a second support block 83.

[0059] like Figure 10 and Figure 11As shown, support holes 92 are symmetrically provided on both sides of the gas detector 9 , and the first support block 73 and the second support block 83 are inserted into the support holes 92 when supporting the gas detector 9 .

[0060] When installing the gas detector 9, the mounting support bar 91 on the gas detector 9 is inserted into the mounting connection groove 41 on the mounting movable plate 4 to realize the positioning and placement of the gas detector 9, and then the electric telescopic rod 11 is started to drive the mounting carrier 2 to move upward. As the mounting carrier 2 moves upward, the pushing and pulling matching rod 40 will drive the mounting movable plate 4 to move in the direction of the stable bearing rod 12, and then the gas detector 9 can be driven to move horizontally to reach the working point, and the movement of the mounting movable plate 4 will also drive the connecting plate 7 to move along the supporting bearing rod 34. As the mounting movable plate 4 moves, the distance between the movable carrier plate 5 and the bearing matching rod 24 will become larger, so that the driving rod 53 will be driven to drive the driving plate 5 to move horizontally to reach the working point. When the connecting plate 3 moves, the moving carrier strip 54 will be driven to move synchronously with the moving carrier strip 54 as the driving connecting plate 3 moves. As the moving carrier strip 54 moves, the upper end of the bar frame 26 will be pushed upward by the upper moving column 56 to its lower end, which will also drive the moving carrier strip 54 to move downward relative to the driving connecting plate 3, thereby driving the movable carrier plate 5 to move downward, thereby making the limit baffle 52 block the end face of the gas detector 9, thereby fixing the gas detector 9. In addition, when the driving connecting plate 3 moves, it will also drive the connecting connecting plate 7 to move in the direction of the gas detector 9. As the connecting connecting plate 7 moves, the inclined frame 63 will be pushed away from the installation movable plate 4 under the action of the first support plate 72. At the same time, as the connecting connecting plate 7 moves The first support block 73 on the first support plate 72 will be inserted into the support socket 92 on one side of the gas detector 9. In addition, when the connecting carrier block 6 moves in the direction away from the installation movable plate 4, the pushing carrier block 65 on the other side of the connecting carrier block 6 will push the inclined surface 82 to move, which will drive the second support plate 8 to move in the direction of the gas detector 9, so that the second support block 83 on the second support plate 8 is inserted into the support socket 92 on the other side of the gas detector 9. In this way, under the joint action of the first support block 73 and the second support block 83, the gas detector 9 can be well supported, which fully ensures the stability of the gas detector 9 during operation. When the installation carrier 2 moves to the highest point, the gas detector 9 at this time also moves When the gas detector 9 is moved to the working point, the interior of the house 1 can be fully and real-timely detected under the joint action of multiple gas detectors 9, and the fixing of multiple gas detectors 9 does not need to be operated one by one, making the installation of the gas detector 9 very convenient and quick. When the gas detector 9 needs to be maintained, the electric telescopic rod 11 is started to drive the installation carrier 2 to move downward, and then the gas detector 9 can be driven to move downward to reduce its height, making it convenient for the staff to remove it. At the same time, as the installation carrier 2 moves downward, the push-pull matching rod 40 will push the installation movable plate 4 to move to the middle position of the house 1, so that the gas detectors 9 are concentrated and easy to take and put. When the installation movable plate 4 moves to the middle position of the house 1,The movable rod 53 is connected to the movable plate 3 and the movable plate 52 is connected to the movable plate 53. The movable plate 52 is connected to the movable plate 53 and the movable plate 52 is connected to the movable plate 53. The movable plate 52 is connected to the movable plate 53 and the movable plate 52 is connected to the movable plate 53. As the first support plate 72 moves in the direction of the support socket 92, the connecting carrier block 6 will be reset under the action of the first spring 62. As the connecting carrier block 6 is reset, the pushing carrier block 65 will no longer restrict the second support plate 8. After the second support plate 8 loses its restriction, it moves in the opposite direction under the action of the second spring 811, so that the second support block 83 on the second support plate 8 exits the support socket 92 on the other side of the gas detector 9. At this time, the gas detector 9 can be removed from the mounting plate 4 for maintenance, which is very convenient and provides great convenience for workers in the installation and removal of the gas detector 9.
