The utility model discloses toolbox for a hot-line working vehicle, and the toolbox is a box body which mainly consists of two storage subspaces. An insulating tool and a small hard tool are respectively placed in the two storage subspaces. The subspace where the insulating tool is placed employs a plurality of cuboid modules which are stacked up and down. The interior of the cuboid modules are respectively provided with a corresponding tool model space through cutting according to the shape and size of a specific tool. The cuboid modules are made of polyethylene materials. The number of the cuboid modules is three, and the external sizes of the three cuboid modules are the same. Moreover, the cuboid modules are stacked up and down, and are respectively an insulating glove module, an insulating tippet module, and an insulating sheath module. At least one side of each cuboid module is provided with a name identification in a pasted manner, wherein the name identification is used for placing the corresponding insulating tool. The toolbox can effectively reduce the friction between insulating tools and between the insulating tool and the interior of the toolbox in a conveying process, guarantees the performance of the live-line working insulating tools, prolongs the service life of the insulating tools, and improves the safety level of the live-line work.
