[0029] The specific working process of this utility model:

[0030] When in use, place the heat-treated gear ring 7 inside the support frame 1, and use a socket wrench to screw the adjusting sleeve 3, so that the adjusting sleeve 3 rotates along the connecting sleeve 4. Under the rotation of the adjusting sleeve 3, the guide groove 21 of the support rod 2 slides along the guide block 41 in the connecting sleeve 4, so that the support rod 2 is extended, so that the two bosses 61 of the abutment block 6 on the support rod 2 abut against the side of the gear ring 7. When all the support rods 2 abut against the side of the gear ring 7, the extended length of the support rod 2 can be observed through the scale line 211.

[0032] The tooling and the gear ring 7 are placed in a quenching device for quenching. The boss 61 on the support rod 2 abuts against the gear ring 7, thereby preventing the gear ring 7 from being deformed during the quenching process.

[0033] After quenching, the boss 61 is separated from the gear ring 7 by screwing the adjusting sleeve 3, and the gear ring 7 is separated from the tooling.
