AI Technical Summary
Existing easily adjustable material low-temperature thermal expansion coefficient sensing moving fixtures require manual loosening and fixing of the fixture when adjusting the fiber optic sensor probe, making the adjustment process cumbersome and difficult to ensure positional consistency, thus affecting measurement accuracy.
The screw structure, which uses a knob and a rotating shaft for transmission, controls the rotation of the screw by rotating the rotating shaft through the knob. The sliding frame slides on the base, and combined with the mechanical self-locking mechanism of the spring, it enables convenient adjustment and fixation of the fiber optic sensor probe.
It simplifies the adjustment process of fiber optic sensor probes, improves the accuracy and consistency of position adjustment, ensures measurement accuracy, and avoids the effects of vibration and temperature changes caused by traditional clamp adjustment.
