The second connection portion 314 is connected with the first concave portion 311 and the extending portion 313 on two sides, included angles between the second connection portion 314 and the first concave portion 311 and the extending portion 313 on two sides are larger than 90 degrees, sharp included angles are avoided, and the line type of the streamline on the outer surface of the outer cover body 310 is further made soft.

In one embodiment, as shown in fig. 2, the streamline structures of the inner surface section and the outer surface section of the first recess 311 are the same, so that the housing body 310 symmetrically presents a reduced image of the fixing base body.

In an embodiment, as shown in fig. 4 and 5, a plurality of first fastening structures 322 are disposed on an inner wall of the fixing base body 320; the at least two first fastening structures 322 are opposite in fastening direction to fasten two sides of the sensor, so as to form a fastening force for fastening the sensor on the surface of the fixing base body 320.

In an embodiment, as shown in fig. 4 and 5, the plurality of first fastening structures 322 are arranged in two rows, and the second through groove 321 is located between the plurality of first fastening structures 322 arranged in two rows. Further, the second through groove 321 abuts against the sensor. After the first fastening structure 322 fastens the sensor, the sensor is in direct contact with the second through groove 321, so that the sensitivity of the sensor to the outside is improved. Furthermore, the first fastening structures 322 respectively located at two sides of the second through-slot 321 are opposite in fastening force. The second through groove 321 partially or completely faces the sensor, so that the sensor communicates with the outside through the second through groove 321 and the first through groove 3111 to perform detection.

In an embodiment, as shown in fig. 4 and 5, the number of the first fastening structures 322 is two, so as to properly reduce the fastening difficulty and facilitate assembly and disassembly. Further, in order to improve the fastening fastness to the sensor, the two first fastening structures 322 are arranged in an interlaced manner, and are respectively fastened to different positions of the sensor in the longitudinal direction. The realization is fixed the buckle of the vertical different positions of sensor, has improved the fixed fastness to the sensor, and the figure of first buckle structure 322 is two, and the buckle dynamics is not too big, is convenient for shirk out the sensor from two first buckle structure 322 under the buckle effect. And meanwhile, the clamping difficulty is relatively reduced during clamping.
