Fourthly, when the position of the antenna 17 needs to be adjusted, the connecting strip 21 can be firstly slid on the limiting strip 12, the connecting strip 21 drives the antenna 17 to be adjusted accordingly, the connection between the reader-writer body 11 and the antenna 17 can be completed through the connecting wire 16 after the adjustment is completed, at the moment, the two first threaded rings 15 can be rotated on the first screw 14, as the two first threaded rings 15 are both sleeved on the first screw 14 in a threaded manner, when the two first threaded rings 15 are rotated to the two ends of the antenna 17, the limiting of the two first threaded rings is completed, so that the distance between the antenna 17 and the RFID tag can be conveniently adjusted when the device is used, and the use effect of the device is effectively improved;
And fifthly, during use, the second threaded ring 25 can be rotated on the second screw 23, so that the position of the inserting column 31 is adjusted, the arch bar 34 fixed with the inserting column 31 is driven to be adjusted along with the inserting column 31, and the inserting rod 51 and the annular rope 54 are driven to be adjusted along with the arch bar 34, so that the device is convenient for adjusting the height of the annular rope 54, is suitable for people with different arm exhibition, and the application range of the device is widened.
Finally, it should be noted that: it is apparent that the above examples are only illustrative of the present invention and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
