In this embodiment, as shown in fig. 1, the receiving portion 41 is located at the other end of the housing 10, and the receiving portion 41 includes a base 411 having a groove at one end. At this time, one end of the connection portion 42 is rotatably and electrically connected to the base 411 through the recess, and the power line is electrically connected to the base 411 through the through hole on the other end of the housing 10, so that the transducer 30 will be supplied with power through the base 411 and the connection portion 42.

Alternatively, the other end of the housing 10 may further have a receiving groove for receiving the base 411, which is fixed on the inner wall of the housing, and at this time, the base 411 is fixed in the receiving groove, so that the receiving portion 41 can be stably fixed on the housing 10.
