[0040] When it is needed to protect the detector body 2 from dust, the control panel 523 is pulled upwards and abuts against the magnetic plate 524 on the side wall of the top plate 3, the magnetic plate 524 fixes the position of the control panel 523 by magnetic attraction, and the control panel 523 pulls the dustproof curtain 51 outside the detector body 2, a plurality of dustproof curtains 51 can filter impurities such as silk, lint and thread, and effectively avoid the impurities from adhering to the surface of the detector body 2.

When the detector body 2 is subjected to a large impact, the vibration sensor 423 cooperates with the controller 424 to de-energize the electromagnetic positioning ring 422, at which time the electromagnetic positioning ring 422 releases the magnetic attraction force on the protective ring 41, and the multiple sets of protective rings 41 move downward under the action of gravity.

[0044] When the multiple sets of protective rings 41 move downward, the through grooves 4314 on the surface of the protective rings 41 pass through the surface of the upper support blocks 4312, the multiple sets of support blocks 4312 at the lowest position are inserted into the support grooves 4313 on the surface of the protective rings 41 at the lowest position, and the multiple sets of support blocks 4312 cooperate with the support grooves 4313 to stably support and position the multiple sets of protective rings 41 at different heights outside the detector body 2.
