[0004] 1. If there is no directional positioning device, the installation operator cannot achieve accurate parallel positioning between the lens protective sleeve axis and the observation hole axis, and each time the lens is inserted and pushed out, it will cause friction between the lens protective sleeve and the inner wall of the observation hole, causing damage to the protective sleeve, and the material of the protective sleeve that falls off may fall into the kiln, causing pollution to the glass liquid;

[0005] 2. The lens protective sleeve is in direct contact with the inner wall of the observation hole for a long time, and the high-temperature observation hole inner wall refractory material will cause ablation to the outer wall of the lens protective sleeve, which may cause leaks and reduce the service life of the outer protective sleeve;

[0006] 3.
