An electric heating tube 11 is provided on the inner bottom wall of the heat treatment box 1, and a groove 12 is opened on the side wall of the heat treatment box 1. The bolts on the bolt rack 5 are heated by the electric heating tube 11, so that the bolts are heat-treated. When the operator pulls the bolt rack 5 to move, the bolt rack 5 is moved into the groove 12, and then the bolts on the bolt rack 5 are taken out, and new bolts are put in for heat treatment.

[0038] Toothed plate parts 6 are fixedly provided at both ends of the movable part 4, and the two toothed plate parts 6 are respectively meshed with the two bidirectional driving rods 2.
