The bottom of the moving rod 6 extends to the top of the crucible 5 and is fixedly provided with a temperature measuring probe 7. The top of the furnace cover 3 is fixedly provided with a supporting tube 4 covered with the top of the moving rod 6. A control component 2 for driving the moving rod 6 to move up and down is arranged on the side of the supporting tube 4 close to the top of the moving rod 6. The control component 2 can drive the temperature measuring probe 7 at the bottom of the moving rod 6 to move up and down inside the crucible 5. The temperature measuring probe 7 is arranged above the middle of the crucible 5. After the temperature measuring probe 7 is connected to the moving rod 6, the moving rod 6 is driven up and down under the action of the control component 2, so that the temperature measuring probe 7 can be better driven to move downward to measure the temperature of the crucible 5, and the moving distance of the moving rod 6 can be applied to the temperature measurement of crucibles 5 of different models, and the use of the control component 2 to drive the temperature measuring probe 7 to move up and down can avoid the problem of requiring personnel to approach the furnace body 1 for operation, which is more convenient and safe to use.
