Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device for building construction. Background Technology

[0002] In the construction process of a building, wall grinding is an important step that directly affects the final decorative effect of the wall. To obtain a smooth and uniform wall surface, hand-held grinding devices are often used to grind the wall surface during construction.

[0003] However, when workers operate existing grinding devices by hand, it is difficult to guarantee the stability and uniformity of the applied force due to human factors. This unstable force application method can easily lead to over-grinding or slanted grinding of the wall surface, affecting the smoothing effect. Furthermore, due to uneven force application, the smoothing effect of the wall surface may result in localized over-grinding or under-grinding, leading to a decrease in the overall flatness and aesthetics of the wall surface. Therefore, we propose a grinding device for building construction. Utility Model Content

[0004] The purpose of this invention is to provide a wall surface smoothing device for building construction. This device offers the advantage of excellent smoothing effect and solves the problem that existing smoothing devices, when operated by hand, are difficult to maintain due to human error, making it hard to ensure the stability and uniformity of the applied force. This unstable force application can easily lead to over-smoothing or uneven grinding of the wall surface, affecting the smoothing effect. Furthermore, due to uneven force application, the wall surface may experience localized over-smoothing or under-smoothing, resulting in a decrease in the overall flatness and aesthetics of the wall surface.
