The power connector 7 is connected to an external power supply. The maximum limit temperature is adjusted by the mechanical temperature switch 4. By pressing different numbers of push switches 6, different numbers of electric heating tubes 8 heat the bearing platform 9. By selecting different numbers of push switches 6, each electric heating tube 8 can work alone, simultaneously or in combination; when the temperature at the bottom of the bearing platform 9 reaches the maximum limit temperature of the mechanical temperature switch 4, the mechanical temperature switch 4 is disconnected, and the entire device is in a power-off state, effectively preventing the bearing platform 9 from overheating; when the temperature at the bottom of the bearing platform 9 reaches the recovery value of the mechanical temperature switch 4, the mechanical temperature switch 4 is closed, the entire device is in a power-on state, and the activated electric heating tube 8 continues to heat the bearing platform 9.

[0029] Example 2
