Adjustable ultrasonic probe for clinical detection

The invention relates to the technical field of medical equipment, and discloses an adjustable ultrasonic probe for clinical detection, which comprises a probe body, a mounting shell, and a liquid coating mechanism and an adjusting mechanism arranged on the mounting shell, when the probe body moves forwards, a coupling agent can be automatically sprayed in front of the forward direction of the probe body through the smearing structure so as to facilitate detection, a rotating shaft in the opposite direction is blocked by a clamping rod and cannot normally rotate, and meanwhile, the coupling agent can be extruded through a rotating roller and an extrusion hole when being guided into the rotating roller so as to damage the overall form; the air between the coupling agent and the skin can be released, so that the influence of the air on detection is reduced, and the detection precision is improved; exhausted gas can be timely pumped out of the connecting shell, so that the influence on subsequent use of the coup
