Problems solved by technology

When the traditional ink fountain is straightened and tightened at the required position, the magic thread in the ink fountain will not be stuck, which is very inconvenient especially when the construction personnel tighten it for a long time
Although the magic thread in the ink fountain can be caught by the middle limit mechanism of the ink fountain after being pulled out for a certain distance on the market, the limit mechanism requires construction personnel to operate with extra force, which is inconvenient to use

Abstract

The invention belongs to the technical field of scribing, and particularly relates to a scribing device used for house and building decoration. The scribing device used for house and building decoration comprises a rope, an adjustment plate, a volute spiral spring reset mechanism, a rope wheel, a sponge B and a telescopic rod B. When the adjustment plate is pressed downwards, the sponge A and thesponge B supply ink to the rope in a squeezing contact mode, and the rope limited by an elastic block A and an elastic block B in a squeezed mode is released according to the lever principle, and thus, ink can be continuously supplied to the rope while the rope can be smoothly pulled out of an ink foundation. In order to continuously keep the rope in a tensioned state, the rope can be limited in the squeezed mode by the elastic block A and the elastic block B in the ink foundation again as long as the adjustment plate is not further pressed downwards by users again so that the rope in the inkfoundation can be limited without independent extra operation by the users, automatic limitation of the rope is achieved, and accordingly, the ink foundation can be used more conveniently. The scribing device is simple in structure and has a good effect in use.

Description

technical field [0001] The invention belongs to the technical field of line drawing, and in particular relates to a line drawing device used for building decoration. Background technique [0002] The ink fountain belongs to a line-drawing tool commonly used in the fields of construction engineering and housing construction engineering. It is usually used for measurement, house construction, and positioning and installation in house construction. The ink fountain has three purposes: first, to make a long straight line; the method is to fix one end of the ink line at the end, pull out the ink line and straighten it to the required position, and then lift the middle section to pop it down; second, the ink tank stores ink , with ink sticks and crutches to draw short straight lines or make marks; third, to draw vertical lines, which is equivalent to being used as a lead pendant. When the traditional ink fountain is straightened and tightened at the required position, the magic t...
