Loop graph picture is not well-balanced clear enough.
Summary of the invention
Present invention aim to address mentioning in background technique, compasses are laborious to use, and drawn circle image is not well-balanced clear enough
The problem of, a kind of Automatic compasses are provided.
In order to solve the above technical problems, technical solution provided by the invention are as follows: Automatic compasses, including the fixed pole pen cap, rotation
Bar, L-type scale connecting rod and paintbrush, fixed pole pen cap bottom are equipped with the center of circle and determine needle, and the swingle, which is arranged in, described to be determined
In the bar pen cap, the swingle bottom is equipped with screw thread rotation screw, is equipped with rectangular nut cap, the fixed pole at the top of the swingle
The tapered thread groove buckled with the screw thread rotation screw fit is equipped in the pen cap, the swingle is equipped with prominent knot
Structure, the protrusion structure are equipped with the lever regulated set of scale of adjustable L-type scale connecting rod effective length, the L-type scale
The short side of connecting rod is fixedly connected with the paintbrush, and the long side of the L-type scale connecting rod passes through the lever regulated set of scale,
The L-type scale connecting rod is connected by the lever regulated set of scale with the protrusion structure, has S type on the fixed pole pen cap
Hollow out line, the protrusion structure can be equipped with spring and pen core in the S type hollow out line inside spin activity, the paintbrush.
As a preferred embodiment, 0 scale of the L-type scale connecting rod is located at close to the end of the paintbrush.
As a preferred embodiment, the fixed pole pen cap is identical with the height of paintbrush below the L-type scale connecting rod.
The present invention has the advantages that a kind of Automatic compasses are provided, it can the person's of eliminating the need for rotational circle regulation bar band animation
The picture circle process of part, can solve part user exert oneself it is uneven, cannot normally rotate the problem of common compasses fixed pole, make institute
It is well-balanced clear to draw circle image.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view of the invention.
Fig. 2 is schematic perspective view of the invention.
It is as shown in the figure: 1, the fixed pole pen cap, 2, swingle, 3, L-type scale connecting rod, 4, paintbrush, 5, the center of circle determine needle, 6, screw thread rotation
Turn screw, 7, rectangular nut cap, 8, tapered thread groove, 9, prominent structure, 10, the lever regulated set of scale, 11, S type hollow out line,
12, spring, 13, pen core.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
In conjunction with attached drawing 1 and attached drawing 2, Automatic compasses, including the fixed pole pen cap 1, swingle 2, L-type scale connecting rod 3 and paintbrush 4,
1 bottom of the fixed pole pen cap is equipped with the center of circle and determines needle 5, and the swingle 2 is arranged in the fixed pole pen cap 1, the rotation
2 bottom of bull stick is equipped with screw thread rotation screw 6, and rectangular nut cap 7 is equipped at the top of the swingle 2, be equipped in the fixed pole pen cap 1 with
The tapered thread groove 8 of the cooperation of screw thread rotation screw 6 buckle, the swingle 2 is equipped with prominent structure 9, described
Prominent structure 9 is equipped with the lever regulated set 10 of scale of adjustable 3 effective length of L-type scale connecting rod, the L-type scale connecting rod 3
Short side be fixedly connected with the paintbrush 4, the long side of the L-type scale connecting rod 3 passes through the lever regulated set 10 of scale,
The L-type scale connecting rod 3 is connected by the lever regulated set 10 of scale with the protrusion structure 9, on the fixed pole pen cap 1
There is S type hollow out line 11, the protrusion structure 9 can be equipped in 11 inside spin of the S type hollow out line activity, the paintbrush 4
Spring 12 and pen core 13.
As a preferred embodiment, 0 scale of the L-type scale connecting rod 3 is located at close to the end of the paintbrush 4.
As a preferred embodiment, the 3 lower section fixed pole pen cap 1 of L-type scale connecting rod is identical with the height of paintbrush 4.
The present invention in the specific implementation, adjusts the lever regulated set of scale first to adjust the radius for needing picture circle, then presses
After rectangular nut cap, swingle sinks, and screw thread rotation screw is along the downward helical rotation of tapered thread groove, at this point, in paintbrush
Pen core can adjust the lever regulated set of scale with pressuring spring to adjust the radius for needing picture circle, unclamp rectangular nut cap, spring according to
Paintbrush is driven to rise by its resilience, L-type scale connecting rod also rises, and drives swingle to rise, screw thread rotation screw edge when rising
Tapered thread groove rise, prominent structure rises along penholder hollow-out part, returns to original state.
The present invention has the advantages that a kind of Automatic compasses are provided, it can the person's of eliminating the need for rotational circle regulation bar band animation
The picture circle process of part, can solve part user exert oneself it is uneven, cannot normally rotate the problem of common compasses fixed pole, make institute
It is well-balanced clear to draw circle image.
The present invention and its embodiments have been described above, this description is no restricted, shown in the drawings
Only one of embodiments of the present invention, actual structure is not limited to this.All in all if the ordinary skill of this field
Personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution phase
As frame mode and embodiment, be within the scope of protection of the invention.
