If the placement position of the rigid RFID tags is inaccurate, the equipment may be unable to process the rigid RFID tags, and it is necessary to position the rigid RFID tags after placement. Therefore, this utility model is proposed to solve the above problems. Utility Model Content

A positioning shaft is installed inside the cylindrical cavity. The two ends of the positioning shaft have a first protrusion and a second protrusion, respectively. Bearings are installed at both ends of the sleeve. Each bearing consists of an outer ring, an inner ring, and several rolling elements. The side of the outer ring of the two bearings that is close to each other is fixedly connected to both ends of the sleeve. The outer side of the corresponding outer ring of the bearing is fixedly connected to the second protrusion on the positioning shaft. A screw barrel assembly, which is positioned between the positioning shaft and two bearings; Two positioning components are mounted on the screw assembly and the sleeve. The screw assembly can drive the two positioning components to move closer to each other to locate the hard RFID tag.

[0006] Preferably, the screw barrel assembly includes: The first screw cylinder is rotatably mounted on the positioning shaft core; The second screw cylinder is rotatably mounted on the positioning shaft core; The coupling is installed at one end of the first and second screw barrels that are close to each other.

[0007] Preferably, both the first and second screws are located inside the cavity of the sleeve, and the coupling is rotatably fitted against the inner wall of the cavity.

[0008] Preferably, the threads of the first and second screw barrels are in opposite directions.

[0009] Preferably, the first screw barrel has a handwheel at one end near the first protrusion on the positioning shaft core, one side of the handwheel on the first screw barrel is fixedly connected to one side of the inner ring of the corresponding bearing, and one side of the handwheel on the first screw barrel is attached to one side of the outer ring of the corresponding bearing.
