Specific embodiment

The technical solution of the utility model is further elaborated with reference to the accompanying drawing.

It is referring to figs. 1 to 5 the compasses of the utility model, including compasses handle 1, compasses neck 2, angle 3, picture foot 4, Compasses handle 1 is connected on compasses neck 2, the top for being installed in picture foot 4 of compasses neck 2, the top of angle 3 and the top for drawing foot 4 It is pivotally connected and rotary shaft is horizontally extending.The lower end of angle 3 is compasses point, can pass through paper and play positioning work With the lower end for drawing foot 4 is paintbrush, and for drawing lines, the spacing composition radius of circle of compasses point and paintbrush end is fixed by changing Position foot 3 and the angle for drawing foot 4 can draw the circle of different radii.

Referring to fig. 2 and shown in Fig. 4, the upper end of compasses neck 2 is bulb 21, and the lower part of compasses handle 1 has with bulb 21 to matching The spherical inner chamber 11 of conjunction, bulb 21 can be embedded in the spherical inner chamber 11 to universal rotational, therefore compasses handle 1 can opposite compasses neck 2 rotate universally, and compasses handle 1 is in the form of a column, and to enhance feel, the diameter of the section in-between in the axial direction of compasses handle 1 is less than its both ends The diameter in portion.Compasses when in use,, can be primary by the continuous twisting of wrist as long as the finger of user holds compasses handle 1 Circle is painted whole, therefore the lines drawn are uniformly smooth, relatively beautiful.

Compasses neck 2 further includes the threaded joints 23 positioned at the lower section of bulb 21, which is ordinatedly arranged There is adjusting nut 22, the height of the adjusting nut 22 is less than the height of threaded joints 23, therefore adjusting nut 22 can be upper and lower Adjustment.It rotates the adjusting nut 22 and moves upwards extruding compasses handle 1, extruding is generated between bulb 21 and spherical inner chamber 11, is caused Frictional force increases, and the movement between compasses handle 1 and compasses neck 2 is tighter, if reversely rotating adjusting nut 22, compasses handle 1 and circle The movement advised between neck 2 is more loose.Therefore, user can by adjusting adjusting nut 22 come adjust compasses handle 1 and compasses neck 2 it Between it is elastic, to adapt to the feel of user.In the present embodiment, the internal diameter of adjusting nut 22 is greater than the diameter of bulb 21, makes Obtaining adjusting nut 22 can be set on compasses neck 2.The outer surface of adjusting nut 22 be equipped with circumferentially arrangement and along the vertical direction The convex ribs of extension, in order to user's rotation.

The lower end for drawing foot 4 is detachably provided with pen core 41, which constitutes the paintbrush.Specifically, it draws under foot 4 End is provided with cylindrical interconnecting piece 42, and the top of interconnecting piece 42 is equipped with external screw thread 421, and the lower end of interconnecting piece 42 offers receiving Chamber, and the open slot 422 vertically extended, pen core 41 are cooperatively disposed in accommodating chamber, and interconnecting piece 42 passes through outer spiral shell Line 421 is arranged with pen core set 43 with being threadedly engaged, and pen core set 43 is offered along its axially extending conical through-hole, pen core set 43 to When upper rotation, conical through-hole can make accommodating chamber to contract, and then clamp and fix pen core 41, and pen core set 43 rotates down When, accommodating chamber expands outwardly, and pen core 41 can be removed from the lower end for drawing foot 4, which is convenient for the replacement of pen core 41.

The lower end of angle 3 is detachably provided with pilot pin 31, and pilot pin 31 constitutes compasses point, when pilot pin 31 is damaged Or after rust, it can be replaced.

The top of angle 3 offers the first hole, and the top for drawing foot 4 offers the second hole, the first hole and the cooperation of the second hole Ground is equipped with bolt 5, and 5 end of bolt is ordinatedly provided with nut 6, and adjusting nut 6 can change angle 3 and draw between foot 4 Elasticity, convenient for adjust radius of circle.It is heavy that the head of first hole and the second Kong Douwei counter sink, nut 6 and bolt 5 is all disposed within In the countersunk head of head bore, so that the surface of compasses is smoother, good appearance.

It is additionally provided with washer 7 between the head and counter sink of bolt 5, the benefit being arranged in this way is first is that avoiding bolt 5 and sinking Abrasion between head bore, second is that feel is preferable when to adjust bolt 5, nut 6.

Compasses handle 1, angle 3, picture foot 4 are all processed by high impact polystyrene, guarantee compasses integral strength.It adjusts Section nut 2 is then made of polyformaldehyde, this is because the wear-resisting property of polyformaldehyde is preferable, it is this kind of frequently to be suitable for processing adjusting nut 2 Using and part easy to wear.

To sum up, the compasses of the utility model are connected between compasses handle and compasses neck by bulb, keep compasses handle opposite Compasses neck rotates universally, as long as finger holds compasses handle when use, passes through the continuous twisting of wrist, so that it may once by circle picture Completely, circle is drawn by the rubbing of finger compared with the prior art, the existing compasses of the compasses very good solution of the utility model Lines have the defects of connector and uneven thickness when picture, and the bead moulding drawn out is uniformly beautiful.

The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention. All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it It is interior.
