Moreover, for an application scene that the workpieces to be detected are densely arranged, the telescopic rod 3 can penetrate through a gap between two adjacent workpieces to be detected, so that the ultrasonic probe 2 is attached to the workpieces to be detected, and the problem that the ultrasonic probe 2 is difficult to penetrate through the gap between two adjacent workpieces to be detected when being held by a tester is solved.

And, because the couplant filling sleeve 4 is internally provided with the containing space 41 for containing the couplant, and the couplant filling sleeve 4 is provided with the opening 42 opposite to the detection end of the ultrasonic probe 2 and used for the couplant to flow out of the containing space 41, the couplant filling sleeve 4 can store a certain amount of couplant, when the ultrasonic probe 2 is attached to a workpiece to be measured, the couplant can flow out of the containing space 41 through the opening 42 and can remove air between the ultrasonic probe 2 and the workpiece to be measured, so that the accuracy of thickness measurement data is improved.

In order to make ultrasonic probe 2 can laminate with the work piece that awaits measuring more, ultrasonic thickness gauge can also include angle adjustment mechanism 5, angle adjustment mechanism 5 installs the first end at telescopic link 3, ultrasonic probe 2 connects in angle adjustment mechanism 5, angle adjustment mechanism 5 constructs to make ultrasonic probe 2 rotate around the axis vertically rotation axis with telescopic link 3, thereby can carry out angle modulation to angle adjustment mechanism 5 in the direction of perpendicular telescopic link 3 axis, make ultrasonic thickness gauge can adapt to different measuring environment, improve the easy operability of thickness measuring and the accuracy of thickness measurement data.
