Specific embodiment:

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

As shown in figs.1-8, a kind of compasses pen, including penholder 1 are equipped with pen core 3 in penholder 1, and 1 bottom of penholder passes through spiral shell Line is connected with pen core lid 2, is installed with first gear 4 vertically in the side at 1 top of penholder, a mounting rod is equipped with above penholder 1 5, it is installed with a needle of compasses 6 at the top of mounting rod 5, is equipped with and the first tooth in the position that 5 bottom of mounting rod corresponds to first gear 4 The second gear 7 that wheel 4 is engaged is equipped with an opening towards right U-shaped connection sheet in first gear 4 and 7 outside mask of second gear 8, two connecting rods 9 for connecting its front-rear side walls are equipped in 8 inner horizontal of U-shaped connection sheet, two connecting rods 9 are located at same perpendicular Interior, the first gear 4 is sheathed on two connecting rods 9 respectively with second gear 7, and one is equipped on 8 left side wall of U-shaped connection sheet and is stretched Contracting bar 10.

It is equipped with the protective shell 11 of a tubular in 5 bottom of mounting rod, the 11 right side bottom end of protective shell is lower than second gear 7 Bottom end, 11 left side bottom end of protective shell are in contact with 1 left side top of penholder.

It is equipped with the first magnet 12 in 11 left side bottom end of protective shell, is equipped on 1 left side top of penholder and cooperates with the first magnet 12 The second magnet 13.

It is equipped with the first notch 14 on 5 right side wall of mounting rod, the second notch 15 is equipped on 1 right side wall of penholder, first lacks Mouth 14 and the second notch 15 are symmetrical arranged centered on telescopic rod 10；With inside mounting rod 5 be equipped with a tape measure 16, in tape measure 16 It is equipped with scale, is equipped with a crotch 17 in the outer end of tape measure 16, the crotch 17, which is pierced by after the first notch 14, to be arranged in first and lack 14 outside of mouth.

The telescopic rod 10 includes a threaded rod 18, and 18 right end of threaded rod and 8 left side wall of U-shaped connection sheet are connected, spiral shell 18 lateral wall of rasp bar is successively arranged fine thread and coarse-pitch thread from left to right；One or so open setting is arranged with outside threaded rod 18 Sleeve 19 is equipped with the internal screw thread cooperated with coarse-pitch thread on the right side of threaded rod on the inner sidewall of 19 right end of sleeve.

A head protector 20 is arranged in the outside of pen core lid 2 and needle of compasses 6.

When the utility model is used, user can be by mounting rod 5 when needing to be changed into compasses state by writing pen Under turning above penholder 1, the head protector 20 at both ends is removed, exposes the pen tip and needle of compasses 6 of pen core 3, in the process, first Magnet 12 separates under the action of the power of user with the second magnet 13, and mounting rod 5 drives first gear 4 and second gear It is relatively rotated between 7, until the pen tip of pen core 3 is contacted with paper with needle of compasses 6, is turned out sleeve 19 at this time, so that Sleeve 19 on inner sidewall gradually stretch out upwards under the cooperation of coarse-pitch thread on screw thread and threaded rod lateral wall by rotation, until sleeve 19 The fine thread on 18 lateral wall of thread contact threaded rod on inner sidewall, because fine thread screw pitch is less than coarse-pitch thread screw pitch, The screw thread in 18 outside of threaded rod cooperate with what fine thread can not be successfully, so that sleeve 19 stops rising and fix； This compasses pen completes transformation from from writing pen to compasses at this time, user can be carried out as compasses using.

When user is before by the utility model as compasses use, it is necessary first to show number to the scale on tape measure Value is calculated, specific calculation are as follows: because the position of notch it is known that in Fig. 6 a length it is known that again because penholder with It is identical that pole length is installed, so c length it is known that α angle can be obtained by measuring in advance, therefore, can be counted in the hope of b length It is as follows to calculate formula, and: b=2a sin (0.5 α) can find out the length value of b according to above-mentioned calculation formula, and because of a length it is known that c Length is it is known that the value of X can be found out according to formula 2aX=bc, and both the value of diameter of a circle drawn by compasses, the value of the X found out was marked In the corresponding position of tape measure；Then it is painted using the compasses after transformation, crotch 17 can be hung on second and lacked by user It at mouth 15, is stuck in crotch 17 on penholder 1, adjusts the distance between penholder and mounting rod 5, tape measure 16 is drawn out mounting rod at this time 5 so as to carry out the display of diameter of a circle size drawn by compasses, and operator can determine according to the size that tape measure is shown The distance between pen tip and needle of compasses are round to carry out picture.

When need be changed by compasses write pen state when, user's rotational sleeve 19 inside first so that sleeve 19 to Lower movement, covers completely on threaded rod 18, and crotch 17 is taken out from the second notch 15, and tape measure 16 is shunk automatically, and crotch 17 blocks In 14 outside of the first notch, it is then rotatablely installed bar 5 or penholder 1, so that the two is in same rectilinear direction, in this process In: it relatively rotates between first gear 4 and second gear 7, until the first magnet 12 and the second mutually actuation of magnet 13, that is, completes Transformation of the compasses to writing pen, can as writing pen come using.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
