Embodiment 1

[0014] Such as figure 1 As shown, a tool for drawing parallel lines includes a handle 1, a locking device 2 and a pen tip 3. The handle 1 is in an inverted V shape, and four pen tips 3 are provided between the two legs of the inverted V shape.

[0015] In this embodiment, a zigzag bracket 4 is provided between the two legs of the inverted V, the pen tip 3 is located at the lower top of the zigzag bracket 4, and the locking device 2 is located at the upper top of the zigzag bracket 4. The locking device 2 locks the zigzag bracket 4. Such a tool for drawing parallel lines can be like a compass, the distance between the pen tips can be adjusted by the locking device 2, and it can be folded for easy carrying.

[0016] The locking device 2 is a common component, which can be an adjusting nut, an adjusting bolt, and the like.

[0017] When in use, first use a ruler and use a pen tip 3 on the right or left to draw parallel lines corresponding to the number of pen tips. If you want to dra...

Embodiment 2

[0019] A tool for drawing parallel lines includes a handle 1, a locking device 2 and a pen head 3. The handle 1 is in the shape of an inverted V, and four pen heads 3 are arranged between the two legs of the inverted V shape. The pen head 3 passes through the locking device 2 Directly fix.

[0020] In this embodiment, a straight-line bracket is provided between the two legs of the inverted V, and the pen tip 3 is directly fixed on the bracket by the locking device 2. When in use, by adjusting the position of each pen tip on the holder through the locking device 2, parallel lines with different distances and multiple parallel lines can be drawn. Moreover, further, the linear bracket may be provided with scales, so that the requirements for different distances of multiple parallel lines can be drawn more accurately.

[0021] The locking device 2 is a common component, which can be an adjusting nut, an adjusting bolt, and the like.

[0022] When in use, first use a ruler and use a pen...

Abstract

The invention discloses a tool for drawing parallel lines, which comprises a shank, a locking device and pen points, wherein the shank is of a reversed V shape; a plurality of pen points are arranged between two pins which form the reversed V shape; the pen points are fixed by the locking device; a support is arranged between the two pins of the reversed V shape; the locking device and the plurality of pen points are arranged on the support; and the distance between the pen points can be adjusted through the locking device. The invention has simple structure, is convenient to carry, can conveniently draw the parallel lines through the matching of the locking device and the plurality of pen points, can meet the special requirement such as the distance of the parallel lines, is extremely convenient, and can be used for teachers, students and related technicists.

Description

Technical field [0001] The invention relates to a stationery, in particular to a tool for drawing parallel lines. Background technique [0002] Among the existing stationery, there are compasses for drawing circles, rulers for drawing straight lines, and some stationery for drawing arcs, but there are few stationery for drawing parallel lines. So when people draw parallel lines, they always draw a straight line first, and then draw other parallel lines based on estimates or general feelings. Sometimes, in order to be more accurate, several straightedges are used for coordination, which is very troublesome. When multiple parallel lines are to be drawn, or there are specific requirements for the distance between parallel lines, the existing operations are difficult to implement or very troublesome. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and provide a tool for drawing parallel lines, which...
