Embodiment Construction

[0008] Depend on figure 1 It can be seen that the adjustable angle plate of the present invention is composed of a steel ruler, a channel-shaped steel ruler, a screw rod, a nut, and a protractor. Cut out a slot with a width of 2MM and a length of 130MM in the middle of the channel-shaped steel ruler. The M4 screw passes through the slot, then passes through the protractor, and is fixed with nuts. The two sides of the M4 screw are flat, and the function is to be stuck in the slot. The center moves up and down without rotating in the circumferential direction. The screw rod is stuck in the groove of the channel-shaped steel ruler. Turn the protractor to adjust the desired angle and tighten the nut to mark the line. The steel ruler, the channel steel ruler and the protractor are all equipped with scale lines, which are convenient for adjustment when marking. The channel steel ruler and the steel ruler are welded together in a T shape, and are used for drawing right angles.

Abstract

The invention discloses a multifunctional angle board and relates to a marker. The multifunctional angle board comprises a protractor, a steel ruler, a groove steel ruler, a screw, a nut and the like. A 2mm-wide slot is formed in the groove steel ruler and used for allowing the protractor to move up and down for adjusting the size, the screw penetrates from the slot prior to penetrating through the protractor to be fixed with the nut, and free adjustment is realized according to required angle and equidistant lines. Equidistant lines, angle lines and right angles can be marked out without conventional marking methods, marking efficiency and marking accuracy are improved, and marking speed is increased.

Description

technical field [0001] The invention relates to a scribing device, which is used for drawing scribing lines. Background technique [0002] In daily study, the drawing tool is an indispensable drawing tool. Whether it is a primary school student, a junior high school student, or a high school student, it is often necessary to draw equidistance lines, right angle lines, and angle lines when drawing. The traditional method is to use two Two angle rulers, one as a reference, and the other as a wire marking, which is more troublesome to draw, and it is also possible that the two rulers are not completely close together, resulting in marking errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adjustable angle plate, which can solve the defects of troublesome marking and large marking error. [0004] In order to solve the above-mentioned technical problems, the drafting tool is proposed, whether it is possible t...
