Line marking instrument and line marking method used on wall surface

Abstract

According to the marking instrument and the marking method used on the wall surface, a main body is divided into two parts, namely the marking instrument and the adjusting device, the adjusting device is divided into two adjusting modes, namely rotation adjusting and translation adjusting, and the two adjusting modes are used in a matched mode during use, namely rotation adjusting is used as coarse adjusting, namely, a target position is quickly close to, and the adjustment is convenient. Translation adjustment is used as accurate adjustment, and light is accurately positioned to a target. As the movement range of light rays is enlarged when the rotation angle of rotation adjustment is reflected to a target object, only rotation adjustment is taken as coarse adjustment, approaching to a target position can be completed very quickly, translation adjustment is taken as accurate adjustment, a gear adjusting part is adopted as a transmission part, namely gear transmission matching is adopted, and the movement range of the light rays is enlarged. The gear adjusting part is rotated in the forward direction or the reverse direction, the marking instrument and the rotation assembly are subjected to relative reciprocating translation together, the gear rotating in the mode is consistent with the actual translation adjusting movement range, and therefore the adjusting precision is easy to control, and the adjusting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of line marking instruments, and in particular relates to a line marking instrument that is convenient for accurate adjustment and portable use and a line marking method used on walls. Background technique [0002] The line marking instrument is widely used, especially suitable for construction, decoration, home improvement and other occasions that need to provide horizontal, vertical and arbitrary angles as reference lines, such as providing horizontal lines, vertical lines or arbitrary angle lines on the wall, etc. When the line marker is used as a reference line on the wall, the base of the line marker needs to be fixed to the wall. Since the existing line markers do not have the function of translation and fine-tuning, it is necessary to position the line marker more accurately. It usually takes several repetitions to complete the position of the reference line on the wall. In addition, after the positio...

Problems solved by technology

[0003] There is also a line marking instrument with a small structure on the market, which can be as large as a conventional steel tape, which is very convenient to carry and store. However, this type of line marking instrument needs to move the entire body of the line marking instrument to find the target. The application range of the marking instrument is small, and it is not suitable for occasions where baseline adjustment is required without changing the reference point
