[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] refer to Figure 1-Figure 4The high-strength small four-fold combination tool box shown in the figure comprises a box shell 1, a storage box 2, a storage box 3 and a box shell 4 which are arranged to be rotated and folded in sequence. The tops of the box shells 1 and 4 are fixedly installed with handles. The top of the box shell 1 is detachably installed with a mounting plate 5. A storage box 6 and a fixed block 7 are fixedly installed on the top of the mounting plate 5. A central axis 8 is fixedly installed on the inner walls of the storage box 6 on both sides away from each other. A rotating sleeve 9 is rotatably sleeved on the central axis 8. A shoulder strap 10 is wound and installed on the rotating sleeve 9. The end of the shoulder strap 10 extends to the outside of the storage box 6 and is fixedly installed on the side of the fixed block 7. Two limit plates 11 are fixedly sleeved on the rotating sleeve 9. The shoulder strap 10 is located between the two limit plates 11. Four rod sliding holes are opened on the side of the storage box 6. Fixed rods 13 are slidably installed in the four rod sliding holes. A plurality of fixed holes are evenly opened on the side of one of the limit plates 11. One end of the four fixed rods 13 extends into four of the fixed holes respectively. The other ends of the four fixed rods 13 are jointly fixedly installed with a control shift plate 12. An elastic torsion element that automatically reverses the rotating sleeve 9 is provided on the central shaft 8. The elastic torsion element includes a torsion spring 14 sleeved on the central shaft 8. Both ends of the torsion spring 14 are respectively fixedly installed on the inner wall of the rotating sleeve 9 and the central shaft 8. A limited reset unit is installed on the control shift plate 12.

[0024] By means of the above structure, when the control shift plate 12 is moved, the fixed plug rod 13 will be driven to move in or out of the fixed socket, thereby fixing or loosening the limit plate 11 and the rotating sleeve 9. When the rotating sleeve 9 is in a loosened state, the staff can pull out the shoulder strap 10 for use, so that the staff can carry the tool box by hand or on the shoulder according to different situations, thereby improving the practicality of the tool box, simple operation and convenient use. When the shoulder strap 10 is not needed, the control shift plate 12 can be pulled to loosen the limit plate 11. At this time, under the elastic force of the torsion spring 14, the rotating sleeve 9 will automatically reverse, and then the shoulder strap 10 can be automatically wound around the rotating sleeve 9 for storage, thereby avoiding affecting the normal use of the tool box due to the long external length of the shoulder strap 10, and having better practicality.

[0025] As a preferred implementation of this embodiment, the limiting reset unit includes a hexagonal guide rod 15 fixedly mounted on the side of the storage box 6, the control shift plate 12 is slidably sleeved on the hexagonal guide rod 15, and an anti-dropping baffle 16 is fixedly mounted on the end of the hexagonal guide rod 15. The advantage of this arrangement is that the control shift plate 12 can be limitedly guided, and the control shift plate 12 can be effectively prevented from falling off the storage box 6.

[0026] Example 2

[0027] As a preferred implementation of this embodiment, a return spring 17 is sleeved on the hexagonal guide rod 15, and the two ends of the return spring 17 are respectively fixedly mounted on the side of the control shift plate 12 and the anti-slip block 16. The advantage of this arrangement is that when the control shift plate 12 is released, the elastic force of the return spring 17 will squeeze and push the control shift plate 12 to automatically return to its original position, thereby driving the fixed plug rod 13 to automatically insert into the fixed plug hole, so that the limit plate 11 and the rotating sleeve 9 are always fixed, and the use is stable and reliable.

[0028] As a preferred implementation of this embodiment, four mounting holes are evenly opened on the top of the mounting plate 5, and mounting bolts are movably installed in the four mounting holes. Four mounting screw holes are evenly opened on the top of the box shell 1, and the bottom ends of the four mounting bolts are respectively threadedly installed in the four mounting screw holes. The advantage of this arrangement is that when the mounting bolts are turned, the mounting plate 5 can be fixed or loosened, thereby achieving the purpose of facilitating the disassembly and replacement of the storage box 6 and the shoulder strap 10.

[0029] As a preferred implementation of this embodiment, two fixed suction cups 18 are fixedly installed at the bottom of the box shell 1 and the box shell 2 4. The advantage of this arrangement is that the tool box can be adsorbed and fixed on the ground when not in use, which can effectively reduce the situation where the tool box falls and is damaged due to accidental collision.

[0030] As a preferred implementation of this embodiment, sponge pads 19 are fixed at the four corners of the box shell 1 and the box shell 2 4. The advantage of this arrangement is that it can effectively reduce the situation where injuries to people are likely to occur due to accidental collision with the toolbox during carrying and use.

[0031] How this utility works:

[0032] When the tool box needs to be carried on the shoulder, the staff can first pull the control shift plate 12 until the fixed plug rod 13 moves out of the fixed plug hole and loosens the limit plate 11 and the rotating sleeve 9. At this time, the staff can pull the shoulder strap 10 outward. After pulling it out to a suitable length, the staff can loosen the control shift plate 12. Under the elastic force of the reset spring 17, the control shift plate 12 will be squeezed and pushed to automatically reset, thereby driving the fixed plug rod 13 to automatically insert into the fixed plug hole, fixing the limit plate 11, the rotating sleeve 9, and the shoulder strap 10. The operation is simple, easy to use, and practical. When the shoulder strap 10 is not needed, the control shift plate 12 can be pulled again to loosen the limit plate 11. At this time, under the elastic force of the torsion spring 14, the rotating sleeve 9 will automatically reverse, and then the shoulder strap 10 can be automatically wound around the rotating sleeve 9 for storage, avoiding the shoulder strap 10 from affecting the normal use of the tool box due to its long external length, and having better practicality.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
