A screw rod 6 is rotatably connected in the adjusting groove 12 through a bearing. The rotation directions of the two ends of the screw rod 6 are opposite, and the two ends of the screw rod 6 are respectively screwed into the two rectangular slides 5. An adjusting wheel 61 is sleeved and fixed in the middle of the screw rod 6. By rotating the screw rod 6, the two rectangular slides 5 are driven to approach or move away synchronously, and the two clamping plates 4 can be driven to approach or move away synchronously, so that the clamping plate 4 abuts against the side wall of the turbine partition, so that it can adapt to turbine partitions of different thicknesses, which is more practical and easy to clamp. The top of the connecting base 1 is fixedly connected with an alignment bracket 2, and the top of the alignment bracket 2 is provided with an alignment line 21. The setting of the alignment line 21 is used to realize the center alignment of the steam turbine partition. The bottom of the clamping base 1 below the adjustment groove 12 is fixedly connected with a connecting seat 3. The bottom of the connecting seat 3 is provided with an arc groove 31. The arc groove 31 cooperates with the arc shape of the steam turbine partition, so that the clamping base 1 can be fixed on the steam turbine partition more stably. The alignment line 21 is parallel to the axial direction of the arc groove 31. When in use, the device is installed accordingly on each steam turbine partition. When installing, the clamping base can be 1 is clamped on the turbine partition, and then the adjusting wheel 61 is manually turned to drive the screw 6 to rotate.
