The present utility model provides the following embodiments.

[0027] As Figure 2 、 Figure 3 and Figure 4 shown, it is a schematic structural diagram of a roundness detection device for a tire mold in this embodiment. In this embodiment, the roundness detection device includes a base 1. A support frame 3 is fixedly connected to the top of the base 1.
