Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 As shown, a fastener heat treatment tool comprises a heat treatment tool body 1 and a placement protection upper layer 4 arranged at its middle position; a placement protection lower layer 5 is arranged at the lower end position of the placement protection upper layer 4; placement through holes 6 are arranged on the placement protection lower layer 5 and the placement protection upper layer 4; an extrusion buckle spring 10 is arranged at the side position of the placement protection upper layer 4, a buckle slope column 11 is arranged at the side position of the extrusion buckle spring 10, a movable adjustment outer column 12 is arranged at the side position of the buckle slope column 11, a connecting movable transverse groove 2 is arranged at the outer position of the movable adjustment outer column 12, and a connecting movable transverse groove 2 is arranged at the side position of the connecting movable transverse groove 2. A connecting movable longitudinal groove 3 is provided at the placement location, and the placement protective upper layer 4 is placed by squeezing the buckling slope column 11 to be clamped into the movable and adjustable outer column 12 through the squeezing buckling spring 10, and the placement protective upper layer 4 can be moved upward and backward by toggling the movable and adjustable outer column 12. The placement protective upper layer 4 and the placement protective lower layer 5 are used for sealing to prevent fasteners from falling off. At the same time, the mobility of the placement protective upper layer 4 is convenient for taking out the fasteners that have been heat-treated inside it. Through the improvement of the utility model, the fastener heat treatment tooling can be conveniently placed, prevented from falling off, and easy to take out, thereby effectively improving the practicality of the fastener heat treatment tooling.

[0023] like Figure 3 As shown, a through groove is provided at the middle position of the movable and adjustable outer column 12, and the inner diameter of the through groove is equal to the outer diameter of the buckled slope column 11, and an extrusion inner column 13 is provided at the side position of the buckled slope column 11, and the outer diameter of the extrusion inner column 13 is equal to the inner diameter of the movable and adjustable outer column 12. The setting of the extrusion inner column 13 is used to extrude the buckled slope column 11, thereby facilitating disassembly.

[0024] like Figure 3As shown, a limiting connecting column 14 is arranged at the outer position of the extruded inner column 13, and the limiting connecting column 14 and the extruded inner column 13 are an integrated structure. A limiting connecting groove 15 is arranged at the outer position of the outer side of the limiting connecting column 14, and the length of the limiting connecting groove 15 is the moving range of the limiting connecting column 14.

When the clamping block passes over the extruded pull-down block 8, the reset jacking spring 9 will lift the pull-down block 8 to limit the position of the clamping block.

[0026] During operation, the fasteners are placed in the protective lower layer 5, and then the heat treatment tooling body 1 is placed on the heating table for heating treatment. The slow heating of the metal ensures that the metal maintains a uniform temperature, and then the immersion stage is used to keep the metal at the appropriate temperature until the desired internal structure is formed. The immersion time is the duration for which the metal is kept at the appropriate temperature. In order to determine the correct length of time, chemical analysis and metal quality are required. For uneven cross-sections, the soaking time can be determined according to the maximum cross-section. Finally, the metal needs to be cooled to room temperature. Depending on the type of metal, there are various ways to cool the metal. The metal may require a cooling medium, liquid, gas or a combination thereof. The cooling rate depends on the metal itself and the cooling medium. After the treatment is completed, the fasteners can be removed.
