[0006] Through the above technical solution, the addition of the rubber sheet can protect the tooling from damage, and the provision of the bottom plate can enable the tooling to be stably placed on its upper surface.

[0007] Preferably, a circular groove is formed on the upper surface of the bottom plate, and a fixing groove is formed on the inner bottom wall of the circular groove.

[0024] The addition of the rubber sheet 7 can protect the tooling from damage, and the setting of the bottom plate 8 can enable the tooling to be stably placed on its upper surface. A circular groove 9 is provided on the upper surface of the bottom plate 8, and a fixing groove 10 is provided on the inner bottom wall of the circular groove 9.
