Scribing device

Abstract

The invention discloses a scribing device, which comprises a transverse H-shaped pedestal, a sliding rod and a slide block, wherein a supporting plate is arranged in a square hole of the slide block; a scale plate is arranged in a groove; a circular penholder penetrates through a penholder penetration hole; an annular pad on the lower part of the circular penholder is arranged on a Z-shaped limiting block; a spring socket is sleeved on the lower part of the penholder to be arranged between the annular pad and the slide block; and a refill is connected with the circular penholder and is arranged on one plane with paper and a board. The transverse H-shaped pedestal is placed at an initial position where scribing is required, the sharp indicating head is adjusted to point at a corresponding scale, and a set screw is screwed up to fix the slide block on the supporting plate. A clamping head is pulled by one hand to draw one or more parallel lines with equal or unequal spaces on the paper, a wood board and the like. The scribing device has the advantages of simple structure, convenience and quickness in operation, stable and reliable work, capability of simultaneously drawing a plurality of parallel lines with equal or unequal spaces, short scribing time and capability of greatly improving the scribing accuracy and the working efficiency.

Description

technical field [0001] The invention relates to a scribing device, which is suitable for drawing required lines or forms on paper and boards. Background technique [0002] For various needs, it is often necessary to draw lines on planes such as paper and wood boards in work. For example, the notebooks we buy every day only have horizontal lines, but we need to draw multiple vertical lines in actual use; sometimes we need to draw lines on blank paper Draw parallel vertical and horizontal lines for tables to record, etc. In the past, marking was mainly done by hand with a scale and a pen, which not only wastes manpower but also has defects such as inaccurate marking, especially when parallel lines need to be drawn. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the invention provides a scribing device with a simple structure, easy operation and high working efficiency. [0004] A scribing device of the present invention includes an...
