The plug plate 112 is guided in the direction of rotation adjustment by the cooperation of the arc-shaped hole 12 and the fastener 13, and the locking of the plug plate 112 at any angle is realized.

[0034] Please refer to Figure 3 and Figure 7 The heating lamp 2 comprises a lampshade 21.

The adjusting frame 11 is adjusted in rotation, so that the lamp tube 22 and the pole piece 5 are kept in a relative state, the infrared light emitted by the lamp tube 22 is concentrated on the pole piece 5, which is conducive to improving the heat radiation utilization rate of the lamp tube 22 and accelerating the drying of the pole piece 5. In some specific embodiments, a clamp is arranged on the plug plate 112 for clamping the lamp tube 22. The lamp tube 22 is fixed by the clamp, which is conducive to the maintenance and replacement of the lamp tube 22.

[0035] Please refer to Figure 2 and Figure 7In the preferred embodiment, the plug-in plate 112 is provided with a fine-tuning hole 1121, and specifically, the length direction of the fine-tuning hole 1121 is consistent with the width direction of the pole piece 5.
