[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 5 The present invention provides an embodiment of an integrated plastic drag box, including a box 1 and a push plate 7. A sleeve 8 is fixedly connected to the box 1, and a spring 9 is fixedly connected to the sleeve 8. One end of the spring 9 away from the sleeve 8 is fixedly connected to a movable plate 10, and one end of the movable plate 10 is fixedly connected to a plug post 11. A round hole 12 is provided on the sleeve 8, and the plug post 11 passes through and is slidably connected in the round hole 12. A plug post 2 13 is fixedly connected to the push plate 7, and the plug post 2 13 is provided with a slot 14. The plug post 11 is clamped in the slot 14. By pressing or lifting the movable plate 10, the plug post 11 can be clamped or released to connect or release the plug post 2 13, so that the plug plate 1 5 and the plug plate 2 6 can be inserted into or pulled out of the slide slot 1 3 and the slide slot 2 4. Therefore, through such a configuration, it is convenient for people to open or lock the box cover 2, increasing the practicality of the plastic drag box.
