Further, the guide plate is an arc-shaped plate matched with the probe.

Further, the clamping block is a plastic block.

The plastic block is in the prior art, can avoid the rigid contact of grip block and probe, does benefit to the protection grip block.

Further, the outer wall of the hand-held rod is provided with a thread surface.

The thread surface can improve the friction force during the handheld operation, and the problem of slipping during the handheld operation is avoided.

Furthermore, the handheld rod is a telescopic rod.

The telescopic rod is the prior art, and the detection of large-size parts is further used.

Compared with the prior art, the utility model, following advantage and beneficial effect have:
