[0032] The fixing rod 5 in the utility model can be referred to in the specific setting Figure 3 ,according to Figure 3 It can be seen that a cavity 53 is provided inside the fixing rod 5, and a sliding groove 54 is provided on the inner wall of the fixing rod 5 along its length direction, which is connected to the cavity 53. A slider 55 is slidably connected in each sliding groove 54. Figure 3 A limit block 51 is provided at one end outside the fixed rod 5, one end of the limit block 51 extends into the cavity 53 of the fixed rod 5 and is fixedly connected to the slider 55, and a support spring 56 is provided in the cavity 53 of the fixed rod 5, one end of the support spring 56 is fixedly connected to one end of the limit block 51 located in the cavity 53, and the other end of the support spring 56 is fixedly connected to the inner wall of the fixed rod 5.

[0033] The connecting rod 4 in the utility model can be referred to when setting it specifically. Figure 2 ,according to Figure 2 It can be seen that the connecting rod 4 is provided with a sliding slot 41 along its length direction, and the bottom end of the connecting rod 4 is provided with a limiting slot 42 which is connected to the sliding slot 41 and cooperates with the limiting block 51; Figure 1 It can be seen that the side walls of the same group of middle interlayers 3 or bottom box 1 are fixedly connected with two fixing rods 5, so that the same group of middle interlayers 3 are fixedly connected with two connecting rods 4 corresponding to the two fixing rods 5 below their own fixing rods 5; continue to refer to Figure 2 It can be seen that the two limit blocks 51 on the two fixed rods 5 connected to the same group of middle interlayer 3 or bottom box 1 are connected through a support pull rod 52, and each connecting rod 4 is provided with a support card slot 43 connected to the limit slot 42 and matched with the support pull rod 52 at the position corresponding to the limit slot 42.

[0034] The limit clamp rod 6 and the limit clamp block 7 in the utility model can be referred to in the specific settings. Figure 1 、 Figure 4 and Figure 5 ,according to Figure 1 、 Figure 4 and Figure 5It can be seen that the limiting card rod 6 is rotatably connected to the side wall of the middle interlayer 3 or the bottom box 1 through the rotating shaft, and a slot 61 for fixing the limiting card block 7 is provided at the end of the limiting card rod 6 away from the rotating shaft, and a positioning rod 62 extending into the slot 61 is further provided at the end of the limiting card rod 6 away from the rotating shaft. The part of the positioning rod 62 located outside the limiting card rod 6 is sleeved with a return spring 63, and one end of the return spring 63 is fixedly connected to the end of the positioning rod 62 located outside the slot 61, and the other end of the return spring 63 is fixedly connected to the limiting card rod 6; continue to refer to Figure 1 、 Figure 4 and Figure 5 Each group of middle interlayers 3 is located below its own limiting clamping rod 6 and is fixedly connected to the cover body 2 with a limiting clamping block 7 that matches the notch 61.

[0035] The working principle of the foldable tool box of this embodiment is as follows: when using the present invention, the limiting lever 6 is first pulled upward, thereby moving the end of the limiting lever 6 located in the notch 61 upward and out of the notch 61. At this time, the limiting lever 6 no longer blocks the limiting block 7. Then, the limiting lever 6 is rotated to separate the limiting lever 6 and the limiting block 7. At this time, the cover 2 can be directly pulled to move the cover 2, thereby causing the cover 2 to drive the connecting rod 4 to slide outside the fixed rod 5 until the limiting block 51 moves to the position of the limiting slot 42. The support spring 56 can pull the limiting block 51 toward the cavity 53, causing the limiting block 51 to be stuck in the limiting slot 42, and the support rod 52 to be stuck in the support slot 43 for support. As the cover 2 is further pulled, the subsequent middle section 3 can be unfolded and supported through the above operation, making it convenient for people to place and find tools.

[0036] When the search is completed, the support rod 52 can be pulled outward, so that the support rod 52 drives the limit block 51 to disengage from the inside of the limit slot 42, and then the connecting rod 4 can slide outside the fixed rod 5, so that the connecting rod 4 can be restored, so that multiple groups of middle interlayers 3 are folded with each other, and at the same time, the cover body 2 is restored to seal the top of the middle interlayer 3. At this time, rotating the limit card rod 6 can make the limit card rod 6 support and limit the outside of the limit card block 7, which is convenient for people to carry.

[0037] In the above embodiment, the utility model provides a foldable tool box, which facilitates the vertical movement of the fixing rod along the connecting rod by setting a sliding slot; the limiting slot can make the limiting block stuck in the limiting slot; the utility model can directly pull the cover body, and make multiple groups of middle sections interlayers unfolded by the connecting rod and the fixing rod, and then make the limiting block stuck in the inside of the limiting slot for limiting support, so that the expansion between the middle sections interlayers is supported, which makes it convenient for people to take or store tools, and then pull the supporting rod to make the limiting block disengage from the inside of the limiting slot, so that the folding between the multiple groups of middle sections interlayers can be completed.
