[0009] Preferably, both the through slot and the mounting hole are elongated, and the through slot is arranged in a horizontal direction.

[0010] Preferably, the first blade and its corresponding mounting piece, and the second blade and its corresponding mounting piece are all integrally cast.

[0011] The beneficial effects of this utility model are as follows:

[0012] The through-groove design on the mounting plate in this utility model ensures the hinged connection between the first blade and the second blade, while allowing the guide post to move within the through-groove and enabling relative movement between the first blade and the second blade. At the same time, the long through-groove on the mounting plate of both the first blade and the second blade increases the relative displacement distance between the first blade and the second blade.

[0013] The design of the elongated mounting holes at both ends of the first and second blades in this invention allows the blades to move along their length, reducing the machining accuracy of the holes and slots at the hinge mounting position. It also facilitates fine-tuning of the hinge mounting position after the toolbox is deformed, avoiding affecting the closure of the toolbox. Attached Figure Description

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0018] like Figs. 1-2 The hinge shown includes a first blade 1 and a second blade 2. Both ends of the first blade 1 and the second blade 2 are provided with mounting holes 3 for fixed installation. The mounting holes 3 are all elongated. The elongated design allows for fine adjustment of the installation position of the blades and can effectively reduce the machining accuracy of the mounting slots of the blades at the cabinet or cabinet door. The outer side of the mounting holes 3 is provided with mounting grooves 8 to form a stepped structure. The first blade 1 and the second blade 2 are connected by a displaceable connecting part in the middle.

[0019] The displaceable connecting part comprises a first connecting part fixedly installed on the first blade 1 and a second connecting part fixedly installed on the second blade 2, a guide column 5 is hingedly connected between the first connecting part and the second connecting part, one end of the guide column 5 is provided with a column head, the other end of the guide column 5 is provided with a ring groove by penetrating the first connecting part and the second connecting part, and a baffle 7 is sleeved in the ring groove of the guide column 5, so that the disassembly and assembly of the guide column 5 are realized through cooperation of the baffle 7 and the ring groove, and the maintenance and replacement of the guide column 5 are facilitated.
