When the contact pressure is inconsistent with the preset pressure range in the ultrasonic controller 43, the ultrasonic controller 43 can control the probe mechanical arm 41 to drive the probe body 1 to move through the mechanical arm driving controller 44, specifically, the probe body 1 is driven to be further close to the ultrasonic detection part or slightly far away from the ultrasonic detection part, so that the contact pressure between the probe body 1 and the ultrasonic detection part can be matched with the preset pressure range in the ultrasonic controller 43.
