The lead screw 30 is rotatably connected to the main box body 11. The rubber sleeve 34 is sleeved on the lead screw 30. The rubber sleeve 34 is fixedly connected to one end of the lead screw 30. And the lead screw 30 is rotatably connected to the side wall of the main box body 11. Since the rubber sleeve 34 is made of rubber, there is friction between the rubber sleeve 34 and the side wall of the main box body 11. The drive shaft 27 is rotatably connected to the slider 26. The mating gear 28 is fixedly connected to the drive shaft 27. The driving gear 31 is fixedly connected to the lead screw 30. The driven gear 29 is fixedly connected to the drive shaft 27. The lead screw 30 is threadedly connected to the slider 26. The mating gear 28 meshes with the first gear 22. The driving gear 31 meshes with the driven gear 29.

[0053] In order to drive the first sub-box 13 and the second sub-box 14 to move, a hinge member is further provided. The hinge member includes: a first hinge plate 18, a second hinge plate 19, a third hinge plate 20, a fourth hinge plate 21, a first connecting shaft 16, and a second connecting shaft 17.

[0054] The first hinge plate 18 is hingedly connected to the end wall of the first sub-box 13. The second hinge plate 19 is hingedly connected to the end wall of the first sub-box 13. The third hinge plate 20 is hinged to the end wall of the second sub-box 14. The fourth hinge plate 21 is hinged to the end wall of the second sub-box 14. The first connecting shaft 16 is fixedly connected to one end of the first hinge plate 18. The second connecting shaft 17 is fixedly connected to one end of the third hinge plate 20. The first connecting shaft 16 is fixedly connected to the first gear 22. The second connecting shaft 17 is fixedly connected to the second gear 23. The first connecting shaft 16 passes through the mounting plate 15 and rotates relative to the mounting plate 15. One end of the first connecting shaft 16 is fixedly connected to the first gear 22. The other end of the first connecting shaft 16 is fixedly connected to the first hinge plate 18. The second connecting shaft 17 passes through the mounting plate 15 and rotates relative to the mounting plate 15. One end of the second connecting shaft 17 is fixedly connected to the second gear 23. The other end of the second connecting shaft 17 is fixedly connected to the third hinge plate 20.

[0055] The drive shaft 27 passes through the slider 26 and rotates relative to the slider 26. One end of the drive shaft 27 is fixedly connected to the driven gear 29, and the other end of the drive shaft 27 is fixedly connected to the mating gear 28. One end of the lead screw 30 extends into the cavity 12 and is threadedly connected to the slider 26. The other end of the lead screw 30 passes through the side wall of the main housing 11 and extends outside the main housing 11. A turntable 32 is fixedly connected to the end of the lead screw 30 extending outside the main housing 11, and a handle 33 is fixedly connected to the end wall of the turntable 32.

[0056] Working or installation process:

[0057] When it is necessary to open the first auxiliary box 13 and the second auxiliary box 14, the user holds the handle 33 and rotates the handle 33. The handle 33 drives the lead screw 30 to rotate. The lead screw 30 drives the driving gear 31 to rotate. The lead screw 30 drives the slider 26 to move along the guiding action of the guiding groove 25 by being threadedly connected to the slider 26 and drives the drive shaft 27 to move towards the side close to the first gear 22. And during the process of the slider 26 moving towards the first gear 22, the slider 26 synchronously drives the drive shaft 27 to move. The drive shaft 27 drives the driven gear 29 and the mating gear 28 to move towards the side close to the first gear 22. And during this process, the driving gear 31 is always meshed with the driven gear 29 and the driving gear 31 drives the driven gear 29 to rotate. The driven gear 29 drives the drive shaft 27 to rotate around the axis of the drive shaft 27 itself. The drive shaft 27 drives the mating gear 28 to rotate. The mating gear 28 is always meshed with the first gear 22 and makes the mating gear 28 drive the first gear 22 to rotate during the process of following the slider 26 to move along the extending direction of the guiding groove 25. The first gear 22 drives the first connecting shaft 16 to rotate synchronously. The first connecting shaft 16 drives the first hinged plate 18 to rotate circumferentially around the axis of the first connecting shaft 16. The first hinged plate 18 drives the first auxiliary box 13 to move on the main housing 11. Since the first hinged plate 18 and the second hinged plate 19 are respectively hinged to the end wall of the first auxiliary box 13, the first auxiliary box 13 will not tilt during the process of the first hinged plate 18 driving the first auxiliary box 13 to rotate;

[0058] The first gear 22 drives the second gear 23 to rotate by being meshed with the second gear 23, so that the second gear 23 drives the third hinged plate 20 to rotate through the second connecting shaft 17. The third hinged plate 20 and the fourth hinged plate 21 are hinged to the second auxiliary box 14, and the second auxiliary box 14 follows the third hinged plate 20 to move. And at this time, the first auxiliary box 13 and the second auxiliary box 14 are moved to be erected on the main housing 11. The distance between the first auxiliary box 13 and the second auxiliary box 14 becomes larger, and the first auxiliary box 13 and the second auxiliary box 14 are completely unfolded on the main housing 11.

[0059] During the process of opening the first auxiliary box 13 and the second auxiliary box 14, there is friction between the rubber sleeve 34 and the side wall of the main box body 11. Without external force, the lead screw 30 and the rubber sleeve 34 will not rotate easily. Since the lead screw 30 is threadedly connected to the slider 26, the lead screw 30 limits the position of the slider 26. When the lead screw 30 does not rotate, the slider 26 will not slide. And because the lead screw 30 does not rotate easily, the driving gear 31 will not rotate easily either. The driving gear 31 limits the rotation of the driven gear 29, making the driven gear 29 not rotate. The non-rotation of the driven gear 29 drives the mating gear 28 not to rotate. The driven gear 29 limits the rotation of the first gear 22. By limiting the rotation of the first gear 22 and the second gear 23, the first auxiliary box 13 and the second auxiliary box 14 will not move easily without being subjected to a large external force.

[0060] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
