The hinge device of the tool box, wherein the card slot groove and the hook bar slot are U-shaped slits, and the spacing width of the two ends of the card bar slot is the spacing width of the two ends of the hook bar slot one third.

The hinge device of the tool box, wherein the fastening seat is further recessed with a pair of nano-bar slots for the connecting rod to be embedded.

The hinge device of the tool box, wherein the hooking rod has a hooking section which is raised upwards.

The enhancements obtained by the technical means of the present invention include: 1. The invention directly utilizes the hoop-type hinge fastener to hingeably connect the plastic blowing box body and the metal cover body, the overall structure is extremely simplified, and the manufacturing process and the assembly combination are both It is quite simple and easy, and the cost of implementation and utilization is low, and it has great industrial utilization value. 2. The hoop-type hinge fastener of the present invention can be pre-bonded to the pivot joint of the cover body and directly fastened to the buckle seat of the box body, and can be applied to various forms such as a general tool box or a heterogeneous composite tool box. The tool box is flexible and convenient to implement. 3. The invention allows the cover body to be fastened to the buckle seat of the box body by the hinge fastener, and both the manufacturer and the consumer can easily disassemble and replace the different metal cover body or the plastic blow box, thereby improving the tool box. Decorative design such as styling, color and pattern to meet the modern consumer demand for new, diverse and personalized.
