Hydrogen determination probe rod driving device

The invention discloses a hydrogen determination probe rod driving device, which is characterized in that a lifting mechanism is mounted on a supporting seat and is suspended above a detection opening; at least two groups of driving pinch rollers and driven pinch rollers are mounted on a base of the lifting mechanism, the driving pinch rollers and the driven pinch rollers extrude a hydrogen determination probe rod from two sides respectively, and the hydrogen determination probe rod is kept vertical through extrusion of the driving pinch rollers and the driven pinch rollers; the driving pinch roller is driven by a driver through a transmission assembly to rotate, the driving pinch roller drives the hydrogen determination probe rod to vertically lift and move, and the driven pinch roller synchronously rotates during moving; the hydrogen determination probe rod is vertically moved by controlling the rotation of the driving pinch roller, manual operation is not needed, and the hydrogen determination probe rod ca
