An operation procedure of the packing box provided in this application is as follows, when the packing box 100 is in the locked state, the elastic protruding portion 21 abuts against the first abutting portion 13, and it is difficult to take out the inner box from the outer box in a push-pull manner. When the elastic protruding portion 21 is pressed by using the external force, the elastic protruding portion 21 is staggered with the first abutting portion 13. In this case, the packing box is in the unlocked state, and the inner box 20 can be conveniently pushed (pulled) out from the outer box 10 at the second through hole 19 (or the notch 12). When the inner box 20 is pulled out from the outer box 10 to a certain degree, the elastic protruding portion 21 abuts against the second abutting portion 16, to prevent the inner box 20 from being further pulled out. In this case, the article placed in the inner lining 30 has been completely expose to the user, and the user may take out the article in the packing box 100. After the packing box 100 is opened, the user may push back the inner box 20 to the outer box 10. In a process of pushing back the inner box 20 to the outer box 10, the elastic protruding portion 21 may rebound to the recessed portion 14, so that the elastic protruding portion 21 abuts against the first abutting portion 13, and the packing box 100 returns to the locked state.

In the packing box 100 provided in the embodiments of this application, a locking structure is formed by using the elastic protruding portion 21 and the first abutting portion 13, and the locking structure is relatively simple. The locked state can be released by pressing the elastic protruding portion 21 by using a finger, and the unlock is very convenient. Because the locking structure of the packing box 100 is arranged in the first accommodating cavity, the unlocking position is relatively concealed, which can effectively prevent children from opening by mistake. In addition, the packing box 100 may be a full paper packing box. Compared with a box made of a plastic accessory, the full paper packing box 100 is easy to recycle, can meet a requirement for environmental protection, and reduces the manufacturing costs and the manual assembly costs.
