[0027] Further, the automatic clamping mechanism 4 includes a shell 401, and one side outer wall of the shell 401 is fixed to the side wall of the outer box 3, the inner wall of the shell 401 is rotatably connected to the shaft 402, and the outer wall of the shaft 402 is fixedly connected to the connecting gear 403, a side wall of the shell 401 is penetrated by a slide groove 404, and the inner wall of the slide groove 404 is slidably connected to a plate 405, the outer wall of the plate 405 is symmetrically fixedly connected to a connecting plate 406, and one side wall of the connecting plate 406 is fixedly connected to a return spring 407, and the other end of the return spring 407 is fixedly connected to the inner wall of one side of the shell 401;

[0028] More specifically, in this embodiment, when the wooden packaging box is used, the articles are first placed inside the inner box 2, and then the outer box 3 is arranged by fitting the outer wall of the inner box 2, so that the outer box 3 can be directly covered on the outer wall of the inner box 2 and continuously pressed down to be inserted;

[0029] During the downward pressing and inserting process, the shaft 402 is rotatably connected to the inner wall of the housing 401, and the outer wall of the shaft 402 is fixedly connected to the connecting gear 403, and the top of the base 1 is symmetrically fixedly connected to the bonding plate 5, and the two side walls of the bonding plate 5 are provided with tooth grooves 6, and the inner wall of the tooth groove 6 matches the gear teeth of the connecting gear 403, so that the connecting gear 403 can rotate along the tooth groove 6;

[0030] Then, during the counterclockwise rotation of the connecting gear 403, the connecting plate 406 is symmetrically fixedly connected through the outer wall of the push plate 405, and a return spring 407 is fixedly connected to one side wall of the connecting plate 406, and the push plate 405 forms a telescopic structure with the return spring 407 through the connecting plate 406, and at the same time, the push plate 405 is bent toward one end of the connecting gear 403, so that during the counterclockwise rotation of the connecting gear 403, the bent end of the push plate 405 is squeezed by the gear teeth, so that the push plate 405 will move away from the connecting gear 403 and squeeze the return spring 407 through the connecting plate 406, and when the gear teeth of the connecting gear 403 slide over the curved end surface of the push plate 405, it will return to its original position again driven by the return spring 407, so that the outer box 3 can be continuously pressed down until the top inner wall of the outer box 3 fits the article;

[0031] When the top inner wall of the outer box 3 fits the article, the article will block the downward movement of the outer box 3, and when the outer box 3 moves upward, the connecting gear 403 will rotate clockwise, and the curved end surface of the abutment plate 405 will limit and block the gear teeth of the connecting gear 403, so as to achieve the effect of automatic locking and keep the fit state with the article;

[0032] When it is necessary to take out the items, at this time, the pull rod 408 is connected to the end of the support plate 405 away from the connecting gear 403 by rotating, so that the pull rod 408 can be pulled outward to drive the support plate 405 away from the connecting gear 403, and then the unlocking block 409 is fixedly connected through the outer wall of the pull rod 408, and the two side walls of the unlocking block 409 are fitted with connecting blocks 410, and the same outer wall of the two connecting blocks 410 is provided with an unlocking groove 411 corresponding to the unlocking block 409, and at the same time, the outer wall of the unlocking block 409 is fitted with the inner wall of the unlocking groove 411, so that the unlocking block 409 can be driven by the pull rod 408 to break away from the fit between the connecting block 410, and then the unlocking block 409 is rotated ninety degrees by the pull rod 408, and is stuck in the unlocking groove 411 under the drive of the return spring 407, so that the unlocking state can be continuously maintained, which is convenient for disassembling the outer box 3;

[0033] Then, when the top inner wall of the outer box 3 fits the article, a fixing plate 412 is fixedly connected to the top of the connecting block 410, and the internal thread of the fixing plate 412 is connected to the fixing screw 413, and the outer wall of the fixing screw 413 is threadedly connected to the inside of the pull rod 408, so that the fixing screw 413 can be screwed into the inside of the pull rod 408 to lock the pull rod 408. At this time, the support plate 405 will not be able to move, completing the fixed installation between the inner box 2 and the outer box 3.

[0034] Embodiment 2:

[0035] On the basis of the above embodiment, the top inner wall of the outer box 3 is fixedly connected with an extrusion spring 7 at an equal distance, and the other end of the extrusion spring 7 is fixedly connected with an extrusion plate 8, the outer wall of the extrusion plate 8 slides in contact with the inner wall of the inner box 2, and the bottom of the extrusion plate 8 is sprayed with an anti-slip coating;

[0036] More specifically, in the present embodiment, during the insertion of the outer box 3, an extrusion spring 7 is fixedly connected at equal distances through the top inner wall of the outer box 3, and the other end of the extrusion spring 7 is fixedly connected to a extrusion plate 8, and the outer wall of the extrusion plate 8 slides in contact with the inner wall of the inner box 2, so that the extrusion plate 8 can fit against the surface of the article, and the elastic force of the extrusion spring 7 is used to drive the extrusion plate 8 to extrude the surface of the article, and at the same time, an anti-slip coating is sprayed on the bottom of the extrusion plate 8, so as to increase the friction between the extrusion plate 8 and the surface of the article, thereby preventing the articles inside the box from moving randomly during transportation, and ensuring the protective performance of the present wooden packaging box.

[0037] Working principle: first, place the items inside the inner box 2, then cover the outer box 3 on the outer wall of the inner box 2 and continue to press down to insert. During the process of pressing down and inserting, the connecting gear 403 will rotate along the tooth groove 6, and continuously squeeze the curved end of the abutment plate 405 through the gear teeth. When the top inner wall of the outer box 3 fits the items, the items will block the downward movement of the outer box 3. When the outer box 3 moves up, the connecting gear 403 will rotate clockwise. At this time, the curved end of the abutment plate 405 will be used to limit and block the gear teeth of the connecting gear 403, so as to achieve the effect of automatic locking. At this time, the fixing screw 413 can be screwed into the inside of the pull rod 408 to complete the locking of the pull rod 408.

[0038] Then, during the insertion of the outer box 3, the squeezing plate 8 can be made to fit with the surface of the article, and the elastic force of the squeezing spring 7 is used to drive the squeezing plate 8 to squeeze the surface of the article. At the same time, the bottom of the squeezing plate 8 is sprayed with an anti-slip coating, thereby increasing the friction between the squeezing plate 8 and the surface of the article, thereby preventing the articles inside the box from moving randomly during transportation;

[0039] When the item needs to be taken out, first unscrew the fixing screw 413 from the pull rod 408, then pull the pull rod 408 outward to drive the unlocking block 409 to break away from the fit between the connecting block 410, and then use the pull rod 408 to rotate the unlocking block 409 ninety degrees, and drive the return spring 407 to insert it into the unlocking groove 411, so that the unlocking state can be maintained continuously, making it easy to disassemble the outer box 3.
