This invention provides a probe holder device for an
ultrasonic testing instrument, comprising a body, a probe, a fixing mechanism, a multi-stage rotating device, and a clamping mechanism. The probe is connected to the body via a cable and placed within the clamping mechanism. The clamping mechanism adjusts its position following the multi-stage rotating device. The multi-stage rotating device includes a primary rotating mechanism that drives the clamping mechanism to rotate laterally and a secondary rotating mechanism that drives the clamping mechanism to rotate longitudinally. The primary rotating mechanism is mounted on the fixing mechanism, and the secondary rotating mechanism is mounted on the primary rotating mechanism. The fixing mechanism secures the multi-stage rotating device to the body. This
ultrasonic testing instrument probe holder device, by incorporating a multi-stage rotating device, enables multi-angle adjustment of the probe both laterally and longitudinally, significantly improving the flexibility and convenience of probe placement and adapting to the demands of a fast-paced hospital testing environment.
