Description

Technical Field

[0002] Steel structure is mainly made of steel plates, which is one of the main types of building structures. Therefore, steel structure must be fine during construction, especially in terms of details. A slight deviation may cause the project to stop or even rework, affecting the progress of the project construction, and even worse, causing personal injury. Therefore, when processing steel structures, it is necessary to clamp and fix the steel plates, and then grind and polish them to ensure the safety of construction. However, most polishing devices on the market are too rigid in design, inconvenient for multi-angle adjustment, unable to accurately polish the steel plates at all angles, unable to make the polishing disc grind different areas during use, affecting production and processing, reducing work efficiency and work quality, and inconvenient to stably clamp according to the size and thickness of the steel. Accidental sliding is prone to occur during polishing, which can easily lead to instability of the steel body, resulting in defects in grinding and polishing, failing to meet standard requirements, affecting production and processing, and resulting in low production efficiency. For this reason, we have launched the following device. Utility Model Content
