Problems solved by technology

However, the existing compasses can’t realize the stability of the angle between the rotating leg and the central leg in drawing, and it needs cooperation between multiple fingers to control the drawing of the compasses. It is more difficult, even for adults, it needs high technical requirements; especially when drawing small circles or large radius circles or arcs, the angle between the drawing rotation foot and the center foot is even more difficult to control
In addition, the axial position between the central leg and the drawing swivel leg is not adjustable in the conventional compass. Even if an adjustable fixed pencil fixing part is set on the drawing swivel leg, the relationship between the center leg and the drawing swivel leg cannot be solved well. The relative fixation of the rotating feet makes the radius of the circle or arc drawn by the compasses greatly restricted, that is, the drawing radius of the compasses is greatly restricted, which reduces the applicability of the compasses. Multiple compasses should be equipped to solve the problem. these questions

Embodiment 1

[0059] see figure 1 , figure 2 and Figure 8 to Figure 12 , the present invention discloses a compass that is convenient for teenagers to use. In the present embodiment, the compass is a compass-100, which includes a center leg 110 and a drawing rotating leg 120; the center leg 110 and the drawing rotating leg 120 are rod-shaped parts; The center leg 110 is slidably provided with a lifting adjustment assembly 140, the lifting adjustment assembly 140 includes a positioning sleeve 141, a sliding cavity 149 is arranged inside the positioning sleeve, and a positioning assembly 142 fixed to the center leg is arranged outside the positioning sleeve, The other side of the positioning sleeve 141 is provided with an L-shaped angle adjustment plate 145; the L-shaped angle adjustment plate 145 includes a connector and an arc-shaped angle adjustment plate 147 perpendicular to the connector; The fixed sleeve is equipped with an angle adjustment assembly 130, and the angle adjustment ass...

Embodiment 2

[0068] On the basis of embodiment 1, refer to Figure 3 to Figure 7 , Figure 13 to Figure 15 , the compasses form compasses two 200, and compasses two includes all the technical features of compasses one, and the center leg 110 of compasses two is provided with a hinge adjustment part 150 corresponding to the top of the drawing rotation leg 120; the hinge adjustment part 150 It includes a receiving part 151 arranged on the top of the center leg, and an accommodating cavity 153 is arranged in the accommodating part, and a guide rod 154 is arranged obliquely along the height direction in the accommodating part; the top of the drawing rotating leg 120 is provided with Hinge piece 152, described hinge piece comprises two hinged lugs 1521 that are arranged oppositely, and the mounting groove 1522 is formed between two described hinged lugs; The hinge 155 is slidably sleeved on the guide rod 154 . In this embodiment, the drawing swivel foot is matched with the hinge and the guide...

Abstract

The invention discloses a compass convenient for teenagers to use. The compass comprise a central supporting leg and a drawing rotating supporting leg, a lifting adjusting assembly is slidably arranged in the center of the central supporting leg, the lifting adjusting assembly comprises a positioning sleeve, a positioning assembly fixed to the central supporting leg is arranged on the outer side of the positioning sleeve, and an L-shaped angle adjusting plate is arranged on the other side of the positioning sleeve; the L-shaped angle adjusting plate comprises an arc-shaped angle adjusting plate; and an angle adjusting assembly sleeves the drawing rotating supporting leg and comprises a fixing sleeve, one side of the fixing sleeve is fixedly connected with positioning sliding blocks through a connecting rod, and the positioning sliding blocks can be slidably connected along an arc-shaped angle adjusting plate. The design is reasonable and novel, the lifting adjusting assembly can conveniently adjust the relative height of the drawing rotating supporting leg and the center supporting leg, and therefore the drawing radius of the compass is increased; and the angle adjusting assembly can conveniently and efficiently adjust and fix the included angle between the drawing rotating supporting leg and the central supporting leg, the drawing rotating supporting leg is prevented from changing relative to the included angle of the central supporting leg in the drawing process, and the drawing difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of compasses, in particular to a compasses convenient for teenagers to use. Background technique [0002] As a drawing tool, compasses are widely used in junior and senior high school students and in the field of planning and design. General compasses usually include a center leg equipped with a steel needle, a drawing rotating leg equipped with a pencil or an automatic pencil, and the center leg and the drawing rotating leg realize the free opening and closing connection of the two legs through the hinge part provided at the upper end. There is a gauge head for fingers to hold on the part. [0003] When the conventional compass is drawing a circle or an arc, the drawing swivel leg is opened relative to the center leg, and the steel needle at the lower end of the center leg is used as the leg, and the drawing can be completed on paper by the revolution of the pencil at the lower end of the drawing swivel le...
