One end of the return spring 632 is fixedly connected with the closed end of the casing 631, and the other end of the return spring 632 abuts against the ball 633. The diameter of the ball 633 is smaller than the inner diameter of the open end of the housing 631 so that the ball 633 cannot fall from the open end of the housing 631. The return spring 632 is always in a compressed state such that a portion of the ball 633 protrudes from the open end of the housing 631.

Referring to fig. 4, a plurality of grooves 64 are formed on a side of the second hinge support 62 adjacent to the first hinge support 61. The shape of the groove 64 is configured as a hemispherical depression that matches the ball 633. The grooves 64 are uniformly distributed on the same circumference centering on the hinge shaft, and the balls 633 can protrude from the housing 631 and extend into the grooves 64.

When the open end of the housing 631 is misaligned with the groove 64 during relative rotation between the first hinge support 61 and the second hinge support 62, the ball 633 is forced into the housing 631 by the second hinge support 62. As relative rotation between the first and second hinge supports 61 and 62 continues, the open end of the housing 631 is aligned with the recess 64. At this time, the ball 633 is protruded from the housing 631 by the return spring 632, and is caught in the groove 64.

Through the cooperation of the ball plunger 63 and the groove 64, a certain damping feeling can be generated when the first hinge support 61 and the second hinge support 62 rotate. The first hinge support 61 and the second hinge support 62 can rotate relatively, and can keep certain stability when rotating to a corresponding angle, and are not easy to slip or shake.

Meanwhile, the rubber can also play a certain protection role on the probe, and the surface of the probe is not easy to scratch.

Referring to fig. 1, line cards 7 are uniformly distributed on the holding tube 2 along the axial direction. The line card 7 is of an arc-shaped plate structure and encloses a circular space for clamping the probe connecting wire of the flaw detector. When the probe connecting wire is clamped, the wire clamp 7 is broken off, and the connecting wire is put in. Under the condition that some can realize, the material of ply-yarn drill 7 can be plastic material, has certain elastic deformation ability, can the reconversion after taking place deformation.
