Easy-to-move ruler

Abstract

The invention discloses an easy-to-move ruler and belongs to the field drawing tools. The easy-to-move ruler comprises a main ruler body which is structurally L-shaped, a first slider and a second slider; the two sliders which are identical in structure are connected to the lower end and the left end of the main ruler body; stepped holes which are small in the middle and large at two ends are arranged around the axis of the first slider; the center of each of the first slider and the second slider is provided with a press-allowing spring unit; each press-allowing spring unit comprises a button, a spring and a button base; both the button and the button base are T-shaped; the button and the button base is detachably connected; the spring is arranged between the button and the button base; the undersurface of the button base is matched with the lower end face of the small middle hole. By the arrangement of the two sliders, the main ruler body is prevented from rotating during movement, the sliders are separated from the desktop when the main ruler body is unused, and friction between the sliders and the desktop is removed during sliding.

Description

technical field [0001] The invention relates to a straightedge drawing tool, in particular to a conveniently movable straightedge. Background technique [0002] The existing extendable ruler mainly uses a single slide block to fix the direction and slide the main ruler at the same time to achieve the purpose of extension. Notification number is CN104691170A Chinese invention patent "extensible ruler", this invention slides on the main body of the ruler through the slider, and can draw an infinitely long straight line. However, there are defects in such a slider design. When the finger presses the slider, the small area of ​​the slider is stressed. When the main ruler is pushed, it is easy to make the main ruler rotate on the slider as the axis, so that the purpose of drawing a flat extension line cannot be achieved. . When the slider is pushed, due to the friction between the lower surface of the slider and the desktop, it will hinder the sliding of the slider and easily c...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problem that the slider presses a small area and the force causes the main ruler to rotate when it is pushed, and the problem that the lower surface of the slider and the desktop generate friction when the slider is pushed, the invention provides a ruler that can extend in both directions. The ruler can not only Solve the problem of the rotation of the main scale when it is pushed, the friction between the slider and the table, and draw parallel lines
