On.
Further, described penholder union joint includes penholder fixed cover, and the side of penholder fixed cover is hinged with long-armed.
Further, the sidewall of described penholder fixed cover offers screwed hole, is equipped with lock-screw in screwed hole.
Further, described penholder fixed cover is additionally provided with the penholder tapered sleeve being coaxial therewith, the outer conical surface of penholder tapered sleeve
It is provided with on external screw thread, and external screw thread and is combined with nut.
Further, also include that penholder, penholder union joint removably connect with penholder.
Further, described galianconism is provided with anti-rotating hole, and long-armed to be provided with the anti-rotation corresponding with anti-rotating hole protruding.
Further, a side of described galianconism is provided with spacing draw-in groove, long-armed be provided with spacing pocket matches spacing
Sheet.
Further, described galianconism has crimping, and the upper end of described compasses pin is embedded in crimping.
The beneficial effects of the utility model are, form collapsible circle by a leg being made up of long-armed and galianconism etc.
Rule, connect and are attached on pen complete mapping, and the most available pen changes the conventional junction that conventional compasses are made up of two legs
Structure, it is to avoid the drawback of lead for retractable pencil need to frequently be changed by traditional compasses, and eliminates the expense purchasing lead for retractable pencil, effectively changes conventional list
The custom of one pencil mapping, more can be accepted by student and like, compares traditional compasses and produces more simple and fast, and efficiency doubles,
And compasses pin can be packed up, solving the problem that conventional student is easily scratched, used time folding compass can be not up on pen
Pulling, pen can normally write, and compasses pin is the most internally received, and uses safer, and its material, color, shape can spirits as required
Live and change.

Detailed description of the invention
Below by specific embodiment and combine accompanying drawing this utility model is described in further detail.
Fig. 1 to Fig. 8 shows the folding compass that this utility model provides, including penholder union joint 1, long-armed 2, galianconism 3
With compasses pin 4, the upper end of long-armed 2 is hinged with penholder union joint 1, and the lower end of long-armed 2 is hinged with galianconism 3, and compasses pin 4 is fixed on short
On arm 3.This folding compass is installed on the penholder 5 of pencil or ball pen etc. by penholder union joint 1, when not using, turns
Dynamic galianconism 3 makes the needle tip of compasses pin 4 turn to long-armed 2 sides, rotates long-armed 2, makes long-armed 2 upsets to penholder 5 top, and pen can be just
Often write use, such as Fig. 2.
This folding compass also itself can contain penholder 5, and penholder union joint 1 removably connects with penholder 5.Penholder union joint 1
Including penholder fixed cover 6, the side of penholder fixed cover 6 is 2 hinged with long-armed, and penholder fixed cover 6 is enclosed within penholder 5, can be by lock
Tight screw 7 or other frame modes are fixed.Such as Fig. 1 and Fig. 3, the sidewall of penholder fixed cover 6 offers screwed hole, joins in screwed hole
Being provided with lock-screw 7, lock-screw 7 holds out against penholder 5 and i.e. completes to fix, it is possible to as shown in Figure 4, is provided with on penholder fixed cover 6
The penholder tapered sleeve 8 being coaxial therewith, the outer conical surface of penholder tapered sleeve 8 is provided with on external screw thread, and external screw thread and is combined with nut 9, passes through
Interior outer cone thread coordinates to be tightened so that folding compass is installed to penholder 5.
Galianconism 3 is provided with anti-rotating hole 11, and long-armed 2 are provided with the anti-rotation projection 12 corresponding with anti-rotating hole 11, anti-rotation projection 12
For dome shape, when can reach to prevent from using, galianconism 3 the most long-armed 2 rotates, again can when not in use, by artificial force
The more easy and convenient galianconism 3 that makes overcomes the power of anti-rotation projection 12 to rotate relative to long-armed 2 and accept.
One side of galianconism 3 is provided with spacing draw-in groove 13, and long-armed 2 are provided with the banking stop 14 mated with spacing draw-in groove 13, limit
Position draw-in groove 13 can be located at the galianconism side away from penholder 5, i.e. well plays position-limiting action during compasses construction uses, keeps away
Exempt from galianconism 3 during mapping and rotate deflection to side.Galianconism 3 has crimping 10, and the upper end of compasses pin 4 is embedded in crimping 10, such as Fig. 7 institute
Show, convenient installation compasses pin 4.
Long-armed 2 are provided with the spacing rib 15 of position after restriction galianconism 3 the most long-armed 2 overturns, for when not in use, short
Arm 3 rotates relative to long-armed 2 after packing up, and limits galianconism 3 and the position of compasses pin 4, and spacing rib 15 can be located at long-armed 2 away from penholder
The side of 5, makes galianconism 3 and compasses pin 4 sufficiently absorb in long-armed 2.Galianconism 3 and long-armed 2 hinged place be on long-armed 2 arrange
Boss, boss offers screwed hole, uses screw 16 to be screwed onto in the screwed hole of boss through galianconism 3, it is achieved the two hinged.
Turning lock-screw 7, regulation needle point at same position with nib, measures size to be drawn on ruler, takes up one's pen
Compasses pin 4 needle point one side slightly firmly by paper, holds nib and rotates, can draw required circle or curve.No
Used time, unclamping screw 16, pack up tip portion, then tighten screw 16, rotate long-armed 2 to penholder 5 top, pen recovers normally to write
Using, one-object-many-purposes, change the custom of conventional single pencil mapping, needle point can pack up that to allow student use safer.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
