[0021] The lifting mechanism 6 includes a motor 61 fixed to the inner cavity of the casing 2, and a lifting threaded rod 62 is fixed to the output shaft of the motor 61. The other end of the lifting threaded rod 62 rotates on the surface of the connecting plate 5. The surface of the lifting threaded rod 62 is meshed with a detection shell 63. The detector 7 is fixed to the inner cavity of the detection shell 63, and the mesh plate 13 is arranged on one side of the surface of the detection shell 63. In this embodiment, through the arrangement of the motor 61, the lifting threaded rod 62 and the detection shell 63, the staff can use the motor 61, and under the action of the motor 61, the lifting threaded rod 62 rotates, and then under the action of the thread, the detection shell 63 drives the detector 7 to rise and fall.
