The installation shaft 4 extends into the installation opening 911 of the clamp 91. By adjusting the extension length of the installation shaft 4 and the clamp 91, the detection distance of the detection b is controlled. When the installation shaft 4 is adjusted to an appropriate length, the side protrusion 92 on the clamp 91 is threadedly fixed by the bolt c, driving the clamp 91 to clamp the installation shaft 4, so as to ensure the connection stability of the installation shaft 4.
