Embodiment Construction

[0022] See individual figures. The invention relates to square rulers in many forms, and is more suitable for the needs of mapping operations for surveying and drawing.

[0023] Square gauge, consisting of knife gauge 1, knife gauge 1-1, shaft sleeve 1-2, knife ruler tip 1-3, coordinate square 2, shaft 2-1, square gauge 3, hanging shaft square 4, square gauge 5 , Slotted angle gauge 6, slot 6-1, connecting square 7, connecting piece 7-1, protractor 8, protractor 9, small degree scale group 9-1, opening 10, metric ruler 11, foot 12, coordinate ruler 13 , Working edge 14, hole gauge 15, subsquare 16 constitutes.

[0024] Fig. 1 is the plan view of the knife ruler of the present invention. The center of the axle sleeve 1-2 of described ruler gauge 1 and the axis extension line overlap with the starting point and working edge 14 of metric ruler 11 respectively, and one end is provided with ruler tip 1-3, and opening 10 is established at the other end. Wherein, knife ruler gauge...

Abstract

The invention relates to an angle square gauge, which is composed of a cutting square gauge, an axle sleeve, a cutting square tip, an axle, an angle square instrument, a suspended-axle angle square, an angle square gauge, a groove-angle square gauge, a slot, a connecting angle square, a connecting piece, an angle drawing instrument, an angle protractor, a small-scale calibration group, an opening, a metric scale, a foot rule, a coordinatometer, a working edge, a hole gauge and an angle square divider. The angle square gauge is characterized in that the angle of the angle protractor is smaller than the spacing of an angle value through combining the small-scale calibration group, when the angle protractor is arranged into small-angle scale from full scale, the coordinatometer, the angle square instrument, the suspended-axle angle square, the angle square gauge, the groove-angle square, the connecting angle square and the angle drawing instrument are adopted; the angle protractor can only has the form of full angle, the center of the axle sleeve of the cutting square gauge and the extension line of the central axle are respectively coincided with the starting point of the metric scale and the working edge, and simultaneously, two lengths and one angle are measured. The angle square gauge has the functions of a straight ruler, compasses, an angle protractor and a set square, has reasonable structure, high measuring and mapping precision, measuring tools with different forms, is widely used through separation and combination, and can improve the drawing operating efficiency and the drawing benefits.

Description

technical field [0001] The invention relates to a square gauge, specifically a square meter, a square gauge, a drawing angle meter, and a sub-square, which are used for measuring and drawing in drawing operations. Background technique [0002] The existing indexing gauge is used in drawing, carpentry and hardware operations. The central screw does not see the center of the protractor. The angle is set to the whole degree. The working side of the ruler is eccentric, and the angle and length are drawn separately. Not too high. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the above-mentioned prior art, and it is more accurate and faster to provide surveying and drawing, and to adapt to more square gauges, its technical content is as follows: [0004] Square gauge, composed of knife ruler gauge, knife ruler gauge 1-1, shaft sleeve, knife ruler tip, coordinate square, shaft, square meter, hanging axis square, square ga...
