[0031] The arc of the arc-shaped groove 301 is 90° to 175°, so that the human body sensor mounting bracket can be rotated to make the human body sensor point to different positions.

[0032] In the embodiment, the human body sensor comprises an infrared emitter 10 and an infrared receiver 11, and the infrared emitter 10 and the infrared receiver 11 are respectively connected to the mounting seats 801 of the two human body sensor mounting brackets.
