Abstract: The present invention provides a detection device and a detection method. The detection device uses the signal light formed by the interference of the first and the second echo lights reflected on the surface of the component to be detected to obtain the first light intensity distribution information of the signal light corresponding to the sampling position on the component to be detected by the first detection device to obtain the phase distribution of the signal light according to the intensity distribution to obtain the defect distribution data of the component to be detected. Among them, the first detection apparatus includes more than two polarization detectors, or a non-polarization detector and at least one polarization detector.

Abstract: An oil core wrench includes a oneway control unit, a wrench unit and a rotation handle. The wrench unit includes a threaded rod, an adjusting member, a base member and a clamping member. The oneway control unit is mounted in the base member and includes a control member. Thus, the oil core is clamped between the clamping member of the wrench unit and the control member of the oneway control unit so that the wrench unit can drive the oil core to rotate successively in a oneway manner by operation of the oneway control unit, so as to tighten or loosen the oil core easily and quickly. In addition, the oil core wrench can be operated in a narrow or small working region.

Abstract: A combination wrench includes a shank, a first driving member mounted on a first end of the shank, and a second driving member mounted on a second end of the shank. The shank has different cross-sectional profiles and areas from the first driving member to the second driving member so that the shank has different thickness from the first driving member to the second driving member so as to correspond to different forces. Thus, the mediate portion of the shank has a uniform thickness and has greater strength and torque so as to withstand a larger force so that when a stress is concentrated on the mediate portion of the shank, the mediate portion of the shank can tolerate the stress, thereby preventing the shank from being deformed or broken due to an excessive force.
