[0017] A lifting mechanism is disposed on the outer side of the bracket 13, and the bracket 13 can be driven to move up and down under the action of the lifting mechanism.

[0018] In the above solution, the rotating shaft 16 is rotatably connected to the lifting plate 15 via a bearing.

[0019] In the above scheme, a first motor 17 is connected to the top of the rotating shaft 16, and the first motor 17 is installed on the top of the bracket 13. The rotating shaft 16 is driven to rotate by the first motor 17, and then the placement plate 18 is driven to rotate, so that the workpiece is fully in contact with the liquid inside the box 1, so that the quenching effect of the workpiece is more uniform.

[0020] In the above solution, a taking-in and placing groove 2 is provided on the outer side of the placement groove 19. The design of the taking-in and placing groove 2 can facilitate the user to take out the net tube 21 from the placement groove 19 from the side, thus bringing convenience to taking out the workpiece.
