[0034] Embodiment 2:

[0035] The instrument consists of a casing, a methane sensor, an oxygen sensor, a carbon monoxide sensor, a carbon dioxide sensor, a circuit main board, a battery, a liquid crystal display screen, etc. Gases such as methane, oxygen, carbon monoxide, and carbon dioxide in the air are converted into corresponding electrical signals through the corresponding sensor 6. The electrical signals are amplified and filtered, and after being processed by the microcontroller, the concentration values of methane, oxygen, carbon monoxide, and carbon dioxide contained in the corresponding air are displayed in digital form. The gas detection range is as follows: Methane CH4: (0.00~4.00%CH4; O2: (0.0~25.0)%O2; CO: (0~1000)×10-6CO; CO2: (0.00~5.00%)CO2. When the concentrations of methane, carbon monoxide, and carbon dioxide exceed the set alarm points, or when the oxygen concentration is lower than the set alarm value, the instrument vibrates, the buzzer 8 sounds, and the alarm indicator light 9 flashes to indicate that the concentration exceeds the limit. The alarm point setting range is as follows:

[0036] CH4: The full range is adjustable: The factory primary alarm point setting value is 1.00%CH4, and the factory secondary alarm point setting value is 1.50%CH4;

[0037] O2: The full range is adjustable. The factory-set first-level alarm point is 18.0% O2, and the factory-set second-level alarm point is 16.0% O2.

[0038] CO: The full range is adjustable. The factory-set first-level alarm point is 24×10-6 CO, and the factory-set second-level alarm point is 48×10-6 CO.

[0039] CO2: The full range is adjustable. The factory-set first-level alarm point is 0.5% CO2, and the factory-set second-level alarm point is 1.5% CO2.

[0040] Working principle: When using this multi-parameter gas detector, after the instrument is turned on, if the instrument detects that the calibration time has expired, it will remind of the expired calibration alarm when starting up. The menu interface and shutdown password can be set, which is a 4-digit password and is factory-default closed. It automatically stores the collected data and alarm data, and can save up to 100,000 pieces of collected data and 3,000 pieces of alarm data at most. The stored and set data can be cleared, and the factory settings can be restored. The screen-off time can be set to 0 (never screen off) and 1 - 20 minutes. The year, month, day, hour, and minute can be set, and the time interval between the collected data can also be set. In addition, the alarm data with time and date can be exported. The instrument battery is 2 manganese acid lithium batteries in parallel, model: 674048 - 1120 mAh, the highest open-circuit voltage Uo: 4.2V; the maximum output current Io: 2.4A; the rated working voltage Ue: 3.7V; the battery is connected in series with two-level protection circuits and encapsulated with epoxy resin to form an intrinsically safe battery assembly. 20 units can be cascaded, and only one adapter is needed to charge 20 machines simultaneously;

[0041] When carrying, the clamping plate 14 can be pulled. When the clamping plate 14 is subjected to the pulling force, it can drive the rotating shaft 13 to rotate inside the bracket 12. When the clamping plate 14 rotates, it can pull the elastic plate 15 to bend and deform. At this time, the clamping plate 14 and the clamping bottom plate 11 can be clamped on both sides of the staff's belt. Then the clamping plate 14 can be released. At this time, the clamping plate 14 can be reset under the action of the self-elastic force of the elastic plate 15. In this way, clamping can be carried out through the clamping plate 14, and the stability of the clamping can be improved by the teeth at the bottom of the clamping plate 14 and the clamping bottom plate 11.
