To sum up, the utility model discloses overall structure is compact, and is comparatively light, safe in utilization.

Preferably, the bottom surface of the straight plate is provided with a limiting groove used for limiting the adjusting sheet, the axial direction of the limiting groove is consistent with that of the strip-shaped groove, and the width of the adjusting sheet is consistent with that of the limiting groove. The strip-shaped groove limits the axial rotation freedom degree of the adjusting sheet, so that the tightness can be adjusted by rotating the nut body by one hand more conveniently.

Preferably, the straight plate is printed with scales, the starting point of the scales is the axis of the positioning shaft, and the upper surface of the adjusting sheet is marked with an indicating line which is arranged by passing through the axis of the positioning hole. The straight plate member is transparent so that the indicator line on the tab is visible. Thus, the utility model discloses not only can draw the circle of predetermineeing the size fast, can also work as the ruler and use.

Preferably, the adjusting sheet is provided with a sleeve extending upwards, and the sleeve is screwed with the stud.

Preferably, the bottom of the positioning hole is gradually contracted.

Preferably, the top surface of the upper limiting block is provided with an arc-shaped concave part.

Therefore, compared with the prior art, the utility model has the following characteristics: 1. the axis of the positioning shaft is the circle center, the distance between the positioning hole and the positioning shaft is the radius, and the painting brush is inserted into the positioning hole to draw a circle, so that the whole structure is compact, the use is convenient and safe; 2. the straight plate is printed with scales, so that the utility model discloses not only can draw the circle of predetermineeing the size fast, can also work as the ruler and use.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example 1: see fig. 1 and fig. 2, a novel circle drawing tool, including rectangular shape and transparent straight plate 1, set up on the straight plate 1 along its length direction distribution and the strip groove 11 that runs through from top to bottom, wear to be equipped with hollow double-screw bolt 2 in the strip groove 11, the upper end rigid coupling of double-screw bolt 2 is located the nut body 21 of strip groove 11 upside, it has columnar locating hole 22 (see fig. 3) to communicate between nut body 21 upper end and the double-screw bolt 2 lower extreme, the downside that just is located strip groove 11 on the double-screw bolt 2 has connect the regulating plate 3 in a rotating way, the one end of straight plate 1 is rotated and is connected with transparent material location axle 4, the axle center of location axle 4 is located the axis of strip groove 11, the upper and lower extreme of location axle 4 is equipped with spacing piece 41 and lower spacing piece 42 respectively, upper spacing piece 41 and lower spacing piece 42 are transparent material, the bottom surface axle center department of lower spacing piece 42 is equipped.
