Compared with the prior art, the invention has the following beneficial effects:

1. the probe that surveys in this scheme drives the probe that floats and descends along vertical direction, makes the head and the post contact of probe that floats, because of the effect that blocks of post, the afterbody of probe that floats can upwards float the fixed probe of contact, and fixed probe and the probe that floats are connected with the different utmost points of power respectively, adopt the principle of circular telegram conduction to judge the post whether fracture. If the column is not broken, conduction is conducted, and if the column is broken, conduction is not conducted. The scheme fundamentally avoids the condition of missed detection caused by subjective judgment or eye fatigue and the like, can accurately detect whether the product is broken or not, and has the advantages of simple integral structure, low manufacturing cost and high stability of the device.

2. According to the invention, before the detection assembly is used for detection, the device can carry out self-detection, because the floating probe and the fixed probe are disconnected, if the floating probe and the fixed probe are connected before detection, the device is failed, and the detection failure caused by the failure can be prevented by utilizing the device.
