NOVELTY - There is a narrow section between an electrical connection end of a probe and a detection end, one end of the narrow section is connected with a head to the electrical connection end, and the other end is connected with a body to the detection end, the head has a gap, the The body is forced to flex; a cushioning material surrounds the narrow segment; and, a coating is attached to the surface of the probe. The material from the head through the narrow section to the body is different from the material of the cushioning material and the covering layer. In the structure of the probe made of composite material, the gap makes the head have a cushioning function, and the cushioning material surrounds the narrow section against buckling. The body also has a shock absorption effect. The coating layer is a hard nano-scale graphene film, which reduces the wear rate of the electrical connection end and the detection end and ensures that the probe maintains a good electrical contact relationship.
