Therefore, in the present embodiment, by providing the second stiffness adjustment region 1024, the length of the second stiffness adjustment region 1024 can be set according to actual needs, so as to avoid the damage of the engaging portion 102, reduce the wear of the first protruding portion 202 and the second protruding portion 203, and improve the service life of the sampled piece.
Specifically, the larger the width of the first rigidity adjustment region 1023 is, the larger the force required for the sampling terminal to deform, and therefore, in the process of pushing the sampling terminal into the sample object, the larger the width of the first rigidity adjustment region 1023 is, the larger the force required for pushing the sampling terminal into the sample object is, and the smaller the width of the first rigidity adjustment region 1023 is, the smaller the force required for pushing the sampling terminal into the sample object is.
