Abstract
The invention discloses an adjustable angle board and relates to a scribing device. The adjustable angle board comprises an angle gage, a steel ruler, a channel steel ruler, a screw rod, a nut and the like; a groove which is 2 mm in width is formed in the channel steel ruler and allows the angle gage to move up and down; after the size is adjusted, the screw rod penetrates through the groove and then penetrates through the angle gage to be fixed by the nut, so that the adjustable angle board can be adjusted freely according to required angles and equidistant lines. Equidistant lines, angle lines and right angles can be scribed, the traditional scribing method is not required, and the scribing efficiency, the scribing precision and the scribing rate can be improved.
Description
Technical field
The present invention relates to a kind of chalker, for the line of charting.
Background technology
In daily study, the drafting instrument scoring tool that is absolutely necessary, no matter be pupil, junior school student, high school student usually will draw line of equidistance, right-angle line, angle line when drawing, traditional method is to use two bevel protractors, make benchmark for one, another root is done wire line, draw like this get up cumbersome, likely two chis are not close together completely, cause line error yet.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of adjustable angle board, can solve line trouble, the large defect of line error.
In order to solve the problems of the technologies described above, drafting instrument has been proposed to imagination, can, with drawing line of equidistance above root chi, can draw again a comprehensive adjustable angle board of angle line.Adjustable angle board is comprised of protractor, straight steel ruler, U-steel ruler, screw rod, nut etc., in U-steel ruler, there is the groove of a wide 2mm, for protractor, move up and down, adjustment size, screw rod pass from groove, again through protractor, with nut, fix, can freely adjust according to needed angle, line of equidistance.
Adopt the present invention can reach beneficial effect: directly with adjustable angle board, can mark line of equidistance, angle line, right angle, not need traditional scribble method, raising line efficiency, the precision of ruling, the speed of line.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Fig. 1 is the structure chart of the adjustable angle board of the present invention.
The specific embodiment
As shown in Figure 1, adjustable angle board of the present invention is comprised of straight steel ruler, U-steel ruler, screw rod, nut, protractor.U-steel ruler cuts out with line the groove that width is 2MM in centre, and length is at 130MM, by the screw rod of M4 through groove, again through protractor, and fix with nut, M4 screw rod two sides are plane, effect is to be stuck in groove to move up and down, do not do circumferential rotation, by screw rod, be stuck in the groove of U-steel ruler, amount of spin hornwork, adjust want angle number, fastening nut, just can rule.On straight steel ruler and U-steel ruler, protractor, be all provided with graduation mark, the adjustment while being convenient to rule, U-steel ruler becomes T font to weld together with straight steel ruler, for drawing right angle, use.
Material of the present invention is stainless steel.
Claims (2)
1. adjustable angle board, is characterized in that: described straight steel ruler (1) welds together with U-steel ruler (2), and U-steel ruler (2) is connected with protractor (3).
2. adjustable angle board according to claim 1, is characterized in that: described screw rod (5) will pass U-steel ruler (2), then through protractor (3), and be fixed on screw rod (5) with nut (4).
