Adjustable tire pressure detector

An adjustable tire pressure detector installed on a tire rim, the tire rim including two fastening sections at two sides to engage with a tire bead of a tire, a connecting section connecting the two fastening sections, and an assembly through hole disposed at one of the fastening sections, the adjustable tire pressure detector comprising:

• a detector body, disposed at the fastening sections, comprising:
• a housing;
• and
• a gas nozzle assembly hole, penetrating through the housing, comprising two parallel limiting contact surfaces and at least one connecting surface connecting the two limiting contact surfaces;
• a gas intake nozzle, comprising:
• a coupling section, inserted into the gas nozzle assembly hole, comprising two compact surfaces corresponding to and tightly pressing against the limiting contact surfaces, at least one abutting contact surface connecting the two compact surfaces and contacting with the connecting surface, and an assembly hole facing the gas nozzle assembly hole;
• and
• a gas intake section extending from the coupling section towards the assembly through hole, wherein a distance between the two compact surfaces gradually increases from the coupling section towards the gas intake section;
• and
• a gas nozzle assembly member, penetrating through the gas nozzle assembly hole to couple with the assembly hole of the gas intake nozzle to fasten the gas intake nozzle onto the detector body.
