A reset spring 7 is sleeved on the end of the two clamping rods 8 away from the center of the inner cavity of the protective shell 1, and the adjacent ends of the two reset springs 7 are respectively connected to the left and right sides of the protective shell 1 near the center of the bottom, and the two reset springs 7 are respectively connected to the adjacent pull ring 6 near the center of the inner cavity of the protective shell 1 at one end away from the center of the inner cavity of the protective shell 1. Circular holes are provided near the center of the bottom on both sides of the protective shell 1, and the two circular holes are connected with the placement hole. The ends of the two clamping rods 8 away from the center of the inner cavity of the protective shell 1 penetrate the adjacent circular hole cavities and are connected with pull rings 6. The two reset springs 7 can quickly insert the two clamping rods 8 into the adjacent clamping holes, so that the insulating disk can be quickly fixed in the placement hole;

[0025] Embodiment 3: A fixed spring 13 is sleeved on the ends of the plurality of push rods 12 located on the left and right sides near the center of the inner cavity of the protective shell 1, and the ends of the plurality of fixed springs 13 located on the left and right sides away from the center of the inner cavity of the protective shell 1 are connected to the center of the adjacent fixed box 2 near the center of the inner cavity of the protective shell 1, and the ends of the plurality of fixed springs 13 located on the left and right sides near the center of the inner cavity of the protective shell 1 are connected to the center of the adjacent pressure plate 3 away from the center of the inner cavity of the protective shell 1, and the connecting rod pressure plate 3 is driven to close by the action of the plurality of fixed springs 13 on the left and right sides;

At the same time, when the sensor body 5 needs to be cleaned, it is only necessary to pull the sensor body 5 outward to quickly remove the sensor body 5 from the inner cavity of the protective shell 1 for cleaning, so that the gas intelligent sensor can easily pull the adjacent push rods 12 out of the inner cavity of the two fixed boxes 2 through the elastic action of the three fixing springs 13 on the left and right sides. The three push rods 12 can jointly drive the two pressure plates 3 to close and contact the side walls of the sensor body 5, so that the sensor body 5 can be quickly fixed in the protective shell 1 for protective use, avoiding the sensor body 5 from being damaged by external force. At the same time, the sensor body 5 can also be quickly taken out of the protective shell 1 for cleaning, achieving the effect of convenient disassembly and assembly, and improving practicality. When the insulating disk 9 is placed in the inner cavity of the placement hole, the two reset springs 7 begin to extend outward after the external force disappears, so that the two reset springs 7 can drive the two clamping rods 8 to close, so that the two clamping rods 8 can be quickly inserted into the adjacent clamping holes, so that the insulating disk 9 can be quickly fixed in the placement hole, so as to increase the vertical limiting force on the sensor body 5, so that the sensor body 5 can be firmly fixed in the inner cavity of the protective shell 1 for use. After the sensor body 5 is fixed, the staff can start the sensor body 5 for gas detection by connecting the two plugs 10 to the socket. The above is the entire working process of the utility model.
