[0028] Further, the operating member 1 comprises a hand-held portion 11 sleeved on the outer surface of the adjusting member, and a positioning portion 12 extending outward in the axial direction of the hand-held portion 11, the positioning portion 12 is used for sleeving on the surface of the RFID tag to position the same, the adjusting member comprises a knob portion 21, outer extension portions 22 extending outward on both sides of the knob portion 21 in the circumferential direction, and a transmission screw 23 extending in the axial direction of the knob portion 21, the transmission screw 23 is screwed with the hand-held portion 11, the transmission screw 23 is connected with a fixed rod 24 in the axial direction away from the knob portion 21, the movable member comprises a movable shaft 25 movably sleeved on the side of the fixed rod 24 away from the transmission screw 23, and an elastic portion 26 arranged on the side of the movable shaft 25 away from the fixed rod 24, the tension disc 27 comprises a fixed sleeve disc 271 connected with the side of the elastic portion 26 away from the movable shaft 25, a movable inner disc 274 movably arranged in the fixed sleeve disc 271, an elastic block 275 embedded in the fixed sleeve disc 271 and capable of shrinking towards or away from the movable inner disc 274, and a rotating rod 273 extending towards the side of the elastic portion 26 along the movable inner disc 274, at least two sliding grooves 272 for accommodating the rotating rod 273 are formed on the side of the fixed sleeve disc 271 close to the elastic portion 26, the adhesive patch 3 is designed as a single-sided adhesive, and is adhered by the movable inner disc 274 before testing, and is adhered on the surface of the RFID tag after testing, in some optional embodiments, in order to ensure that the adhesive patch 3 causes shielding when covering the RFID tag, the adhesive patch 3 can use a visual plastic sheet made of transparent PV or PC material in the middle position, and is adhered by single-sided adhesive based on the edge of the visual plastic sheet, so that the RFID tag covered in the middle of the adhesive patch 3 can be displayed.

[0029] In the specific implementation, first, the operator can rotate the transmission screw 23 clockwise, sequentially drive the fixed rod 24, the movable shaft 25 and the elastic portion 26 to push the tension disc 27 out of the positioning portion 12 based on the hand-held portion 11 as a reference, and select the adhesive patch 3 suitable for the current RFID tag according to the adhesive strength of the current RFID tag, such as the size of the tag and the adhesive area between the tag itself and the adhesive, adhere the adhesive patch 3 on the surface of the movable inner disc 274 for use, and rotate the transmission screw 23 counterclockwise to make the tension disc 27 enter the positioning portion 12, it should be noted that the contact part between the movable inner disc 274 and the adhesive patch 3 is also provided with single-sided adhesive, and the adhesion between the movable inner disc 274 and other adhesive patches 3 is equal, then the operator can sleeve the positioning portion 12 on the surface of the RFID tag to be tested by holding the hand-held portion 11 to completely cover the same, and then rotate the transmission screw 23 clockwise to control the tension disc 27 to adhere the adhesive patch 3 on the surface of the RFID tag to be tested, in the process, the movable shaft 25 can avoid the rotation of the transmission screw 23 affecting the pulling process of the subsequent adhesive patch 3 after contacting with the RFID tag, thereby causing the adhesive patch 3 to be not firm or directly damaging the RFID tag on the goods.

[0030] Then, the operator can keep one hand pressing the operating member 1, and the other hand rotates the transmission screw 23 counterclockwise to control the pull disc 27 to move to the position close to the handheld part 11, and in the process, the pull disc 27 pulls the adhesive patch 3 and the RFID tag in turn, which can be understood as testing the adhesive strength of the RFID tag by pulling it outward, and the test result in the test process is that the RFID tag is peeled off with the adhesive patch 3 on the goods, and the second is that the adhesive patch 3 is attached to the RFID tag and separated from the movable inner disc 274. The first one is that the adhesive strength of the RFID tag is unqualified, and the second one is that the adhesive strength of the RFID tag is qualified. It needs to be explained that the adhesive strength between the adhesive patch 3 and the movable inner disc 274 is the standard inner strength of the test. The operator can select the glue material that meets the adhesive strength to be brushed on the movable inner disc 274 according to the need. In some optional embodiments, the pull disc 27 can also be a detachable structure, and the operator can replace the pull disc 27 coated with different glue materials for use according to the test strength of the adhesion, and the adhesive patch 3 attached outside is used to strengthen the protection of the surface of the current RFID tag. At the same time, the adhesive patch 3 outside the RFID tag can be further adhered to the goods to improve the adhesive strength between the RFID tag and the goods.

[0031] Further, in some optional embodiments of the present application, in order to improve the efficiency of the adhesive test of the RFID tag, the detection assembly 2 can also be designed independently. The operator can directly hold the adjusting member to control the pull disc 27 to repeatedly pull the RFID tag after covering it, without repeatedly rotating the adjusting member to drive, and the judgment result is the same as above, which can improve the detection efficiency to a certain extent.

[0032] Further, considering that the adhesive strength of the RFID tag may vary when it is adhered to different goods, such as the RFID tag adhered to the surface of the relatively rough goods, which reduces the contact area of the RFID tag due to the rough surface of the goods, and may have a low adhesive strength and be easily torn. On the contrary, such as plate, wood and steel, the adhesive strength is improved in turn and is not easy to tear. Therefore, for the detection of the RFID tag on the easily torn goods, in some optional embodiments of the present application, a spring block 275 is further arranged between the fixed sleeve disc 271 and the movable inner disc 274. The operator can rotate the spring block 275 to the movable inner disc 274 through the rotating rod 273 according to the operation need, and the adhesive patch 3 is directly adhered to the protruding spring block 275, which greatly reduces the contact area between the adhesive patch 3 and the movable inner disc 274, thereby reducing the adhesive strength between the movable inner disc 274 and the adhesive patch 3, so as to adapt to the targeted adhesive strength test operation of the easily torn RFID tag.

[0033] In summary, by wrapping the operation piece to the RFID tag, and by driving the adjusting piece forward, the fixed rod, the movable piece, the tension disc are sequentially driven to adhere the adhesive patch to the RFID tag, then the adjusting piece is driven reversely to pull the adhesive patch and pull the RFID tag outward, and the stress is uniform, and the state between the RFID tag and the adhesive patch 3 is judged, if the RFID tag is peeled off with the adhesive patch 3 on the goods, the current RFID tag adhesion strength is unqualified, if the adhesive patch 3 is attached to the RFID tag and separated from the movable inner disc 274, the current RFID tag adhesion strength is qualified, the problem that the current RFID tag adhesion test is usually manually peeled off and observed, the test mode is more troublesome, and the label is easy to be damaged in the peeling process is solved.
