In operation, because the magnetic poles of the five magnets 71 and the six magnets 72 at the end facing the first partition plate 7 are opposite, when the locking insert plate 3 is twisted in the tag main body 1, the five magnets 71 and the six magnets 72 repel the three magnets 31 and the four magnets 32 on the locking insert plate 3, so that the pressure sensor 73 between the five magnets 71 and the six magnets 72 cannot contact with the locking insert plate 3, and cannot transmit signals, and further can send a warning to a terminal that the positioning auxiliary tag is not locked. Meanwhile, the accuracy of the installation position of the locking insertion plate 3 in the locking chamber 11 can be fully ensured through the pairing relationship between the five magnet 71 and the three magnet 31, and the six magnet 72 and the four magnet 32, so that the situation that the position of the locking insertion plate 3 deviates to influence the fixation of the locking insertion plate 3 is avoided.
The specific working process is as follows:
when the positioning auxiliary tag is required to be taken down, the electric push rod 4 is controlled to withdraw the extension part 41 of the electric push rod 4, so that the extension part 41 of the electric push rod 4 is separated from the locking inserting plate 3 and the locking inserting plate 3 is outwards withdrawn, when the electric push rod 4 moves towards the opposite side of the installation side of the electric push rod 4, the electric push rod 4 passes through the inclined through hole on the locking insertion plate 3, the extension part 41 of the electric push rod 4 passes through the push rod hole on the locking sliding groove 51, enters the inside of the locking sliding groove 51, contacts with the upper end of the locking sliding block 52, extrudes the locking sliding block 52, generates a downward acting force on the locking sliding block 52, enables the locking sliding block 52 to move downwards to the groove of the locking insertion plate 3 under the extrusion of the extension part 41 of the electric push rod 4 to contact with the locking insertion plate 3, controls the electric push rod 4 to withdraw the extension part 41 of the electric push rod 4 into the electric push rod 4 when the locking state of the positioning label needs to be released, and controls the magnet two 55 to be fixedly installed on the upper surface inside of the locking sliding groove 51 at the moment, the magnet one 53 is fixedly installed on the upper end of the locking sliding block 52, and the magnet one 53 and the magnet two 55 mutually attract each other, under the action of the attractive force between the first magnet 53 and the second magnet 55, the locking slide block 52 slides upwards to contact with the first magnet 53, when the locking slide block 52 moves downwards under the extrusion of the extension part 41 of the electric push rod 4, the locking slide block 52 moves downwards to drive the conducting ring 6 to move downwards together, because the bottom surface of the groove on the locking plugboard 3 is fixedly provided with the conducting post 61, the conducting ring 6 is electrically connected with the electronic element in the positioning element chamber 12 through the transmission circuit, the conducting post 61 is connected with the locking slide block 52, and further a closed loop is formed by the conducting ring 6 and the electronic element in the positioning element chamber 12, when the positioning auxiliary label is detached privately, the closed loop formed by the conducting post 61 and the electronic element in the positioning element chamber 12 is disconnected, so that the electronic element electrically connected with the conducting ring 6 gives an alarm to a terminal, and the outer side of the first magnet 53 at the upper end of the locking slide block 52 is provided with the hemispherical protection layer 54, when the extension 41 of the electric putter 4 is inserted into the locking chute 51, the extension 41 contacts with the hemispherical protection layer 54, and at this time, the upper end of the locking slider 52 is in point contact with the inner wall of the locking chute 51, so that the extension 41 of the electric putter 4 can more easily press the locking slider 52 downwards to move the locking slider 52 towards the groove on the locking insert plate 3, when the locking insert plate 3 passes through the positioning hole to contact with the surface of the first partition plate 7 close to the side of the second locking cavity 112, because the third magnet 31 and the fourth magnet 32 are fixedly installed at the end of the locking insert plate 3 away from the wristband 2, the fifth magnet 71 and the sixth magnet 72 are fixedly installed on the surface of the first partition plate 7 close to the side of the second locking cavity 112, when the locking insert plate 3 is inserted into the label body 1, the third magnet 31 and the fifth magnet 71, and the fourth magnet 32 and the sixth magnet 72 attract each other under the attraction force, and the locking insert plate 3 and the first partition plate 7 are fixedly connected with each other, when the locking inserting plate 3 reaches the accurate position, the locking inserting plate 3 is in contact with the pressure sensor 73, the pressure sensor 73 sends a corresponding signal to an electronic component electrically connected with the pressure sensor 73, and then a prompt is sent to a terminal, the magnetic poles of the five magnet 71 and the six magnet 72 at one end, facing the first partition plate 7, are opposite, so when the locking inserting plate 3 is twisted in the tag main body 1, the five magnet 71 and the six magnet 72 repel the three magnet 31 and the four magnet 32 on the locking inserting plate 3, the pressure sensor 73 between the five magnet 71 and the six magnet 72 cannot be in contact with the locking inserting plate 3, and then signals cannot be transmitted, and then a prompt that the positioning auxiliary tag is not locked can be sent to the terminal.
