The upper end of the connecting part 21 is also formed with a positioning convex nozzle 22 with a diameter smaller than that of the connecting part 21, and the positioning convex nozzle 22 can extend into the guide sliding hole 1 c. The sealing cover M is sealed and clamped in the positioning convex nozzle 22, and the outer peripheral surface of the positioning convex nozzle 22 is sleeved with a gas cylinder sealing gasket D. After the gas cylinder 2 is spirally mounted on the valve body 1, the gas cylinder sealing gasket D is hermetically pressed on the step surface of the lower step hole 1D, so that sealing is formed between the gas cylinder 2 and the valve body 1, and gas is prevented from escaping from the joint of the gas cylinder 2 and the valve body 1 after the sealing cover M is broken.

In the embodiment of the utility model, the central axis of the striker 421 coincides with the central axis of the sealing cover M, an impact distance for making the striker 421 impact downwards is reserved between the striker 421 and the sealing cover M, and a plurality of air release grooves F for facilitating air release are formed on the outer circumferential surface of the striker 421 in an equal radian manner.

The optical heart rate sensor 51 of the present invention uses electro-optical solvent pulse wave tracing to measure heart rate. The optical blood oxygen sensor 52 irradiates red light and infrared light to the skin of a human body, then obtains the red light and the infrared light reflected by the blood vessels under the skin, and finally calculates the blood oxygen through an algorithm. Whether the human body is healthy or not is judged by measuring the blood oxygen saturation of the artery of the human body, wherein the blood oxygen saturation specifically refers to the content ratio of hemoglobin combined with oxygen in blood, namely the concentration of blood oxygen in the blood. Generally, a blood oxygen saturation level of 94% or less is considered as oxygen deficiency. If the condition of insufficient oxygen supply is caused, the normal metabolism of cells is directly influenced, and the life is threatened in serious cases, so the blood oxygen detection is very important. The six-axis attitude sensor 54 includes a six-axis MEMS accelerometer and a gyroscope sensor, and the six-axis MEMS accelerometer and the gyroscope sensor can monitor acceleration data and gyroscope data in three mutually perpendicular directions in a three-dimensional space.
