Problems solved by technology

However, the parallel lines drawn in this way may themselves be skewed. If the requirements are strict, it will be a waste of time to mark the interval first like carpentry.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] figure 1 A gauge according to one embodiment of the invention is schematically shown.

[0022] Such as figure 1 As shown, the measuring tool mainly consists of a bottom plate 1 and a main block 2 . A tracing rule 12 integrally connected with the bottom board 1 is fixed on the bottom board 1 , and the side of the bottom board 1 provided with the tracing rule 12 is called the first side 11 . The main block 2 is provided with a notch 22, and a ruler groove 23 is also arranged in the notch 22. The height of the notch 22 is consistent with the thickness of the bottom plate 1, and the size of the ruler groove 23 is the same as that of the tracing ruler 12, so that the main block 2 can be completely buckled. combined on the bottom plate 1.

[0023] Main piece 2 is a cube, and this side that is provided with breach 22 is called bottom surface 21, and the o...

Abstract

The invention discloses a measuring tool which comprises a base plate and a main block. The base plate comprises a drawing ruler fixed on a first face, a notch is formed in the bottom face of the main block, a ruler groove is further formed in the notch, the main block is combined with the base plate through the notch in a buckled mode, the ruler groove is combined with the drawing ruler in a buckled mode, and scales are marked on the drawing ruler. An object is placed on the first face of the base plate, wherein lines need to be drawn on the object, a straight ruler is used, one end of the straight ruler abuts against the surface of the main block, a first line is drawn on the object, then the base plate is moved, another line is drawn through the straight ruler in the same mode, and thus the line is absolutely parallel to the first line. Only the base plate needs to be moved at will, needed parallel lines can be safely drawn, and compared with ordinary operation, operation through the measuring tool is rapider and more accurate. Due to the fact that the scales are added on the drawing ruler, the number of moved intervals of the base plate can be learned, and the intervals of the parallel lines can be determined in the process of drawing the parallel lines.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a combined measuring tool. Background technique [0002] General measuring tools, especially manual measuring tools for carpentry, such as steel rulers used for marking lines such as tenons, starting lines, groove lines, etc., have certain limitations in use. [0003] In the face of the situation where parallel lines need to be marked repeatedly, many pre-order steps need to be done. First, use a square to determine the two vertical axes, then mark the interval between parallel lines, and finally draw the line with a steel ruler. If the surface marked with parallel lines is a curved surface, the situation is more complicated, and it is necessary to scalar the side of the curved surface, which is very troublesome. [0004] In addition, as in the study, students often encounter the need to draw parallel lines or mark spacing in their homework. For example, when writing a composition on a blank...
