Tool for heat treatment of long bolt

The utility model relates to a tool for heat treatment of a long bolt, in particular to a tool for heat treatment of a bolt, which aims to solve the problem that the long and thin bolt cannot be kept in a vertical state to be subjected to heat treatment during heat treatment, and comprises an upper panel, a lower panel and a plurality of connecting rods, and the upper panel and the lower panel are arranged in parallel from top to bottom; the upper panel and the lower panel are connected through a plurality of connecting rods 3, the connecting rods are evenly distributed in the circumferential direction, and the bolts are vertically hung on the lower panel. After the tool is used, the long bolt is always kept in a vertical state in the heat treatment and cooling process, each transverse section is in the same state (temperature), stress difference caused by temperature or other factors is avoided, and deformation of the long bolt can be greatly reduced. The utility model belongs to the technical field of machi
