Abstract
An ultrasonic probe device includes a sealed housing, a spiral-track plate, a driving arm, an ultrasonic probe and a first shaft. The spiral-track plate, disposed inside the sealed housing, includes a pivotal hole and a spiral groove, in which the spiral groove is extended outward from a center of the spiral-track plate. The driving arm, adjacent to the spiral-track plate, includes a first slot and a rotational shaft hole. The ultrasonic probe includes a follower pillar, a detection side and a connection side opposing to the detection side. The follower pillar, connected with the connection side, penetrates through the first slot and enters the spiral groove. The spiral groove provides a planar motion track to the detection side of the ultrasonic probe. The first shaft orderly penetrates through the sealed housing, the pivotal hole of the spiral-track plate, and the rotational shaft hole of the driving arm.
