[0002] A kind of etching bag label is disclosed in Chinese patent CN217767565U, which includes a label buckle and a protective bag. The protective bag is used to hold commodities, and the label buckle is installed on the bag opening of the protective bag for anti-theft protection. The label buckle includes a base, at least one lock catch inserted into the base for compressing the protective bag, a top cover installed on the base for shielding the lock catch, and a lock block slidably positioned on the base. The base is provided with an insertion slot for inserting the lock catch and a first conductive plate and a second conductive plate for electrically connecting the alarm circuit of the protective bag and arranged near the insertion slot. The inside of the base is provided with a lock block spring for pushing the lock block, a lock core structure for limiting the movement of the lock block to block the top cover, and a circuit board for electrically connecting the first conductive plate and the second conductive plate. The disadvantages of this etching bag label are as follows: first, the lock catch in the label buckle is a separate component, which may be lost during use; second, the etching bag label needs to be opened first, then the bag opening of the protective bag is placed on the base, then the lock catch is inserted, and finally the top cover is covered, which is inconvenient to use; third, the circuit board of the label buckle and the alarm circuit in the protective bag are electrically connected by compressing the protective bag with the lock catch, which may cause the lock catch to compress the protective bag loosely, resulting in the separation of the label buckle and the protective bag (i.e., the disconnection of the alarm circuit) and false alarm; fourth, the label and the protective bag need to be assembled when protecting the commodities.
