The sliding member 73 has a pushing surface 731 located outward of the outer edge of the pen 71 and facing outward, and a pressing portion 732 facing away from the pushing surface 731. The pushed surface 731 can be subjected to a thrust parallel to the axial line 711 of the sheath 71, so that the sliding member 73 slides down along the sliding slot 710, and the pushed surface 731 has an increased contact. The anti-slip structure 733 of the frictional force, the anti-slip structure 733 of the embodiment is a plurality of horizontally spaced horizontal grooves, but is not limited thereto. For example, the anti-slip structure 733 may also have a plurality of conical shapes. Concave. The pressing portion 732 has a through hole 730 having an inner diameter larger than the outer diameter of the small diameter portion 721 and smaller than the outer diameter of the large diameter portion 722. The pressing portion 732 is sleeved on the sandwich rod 72 by the through hole 730. The small diameter portion 721 abuts against the shoulder portion 724. When the sliding member 73 slides downward, the pressing portion 732 pushes the clamping rod 72 to shorten the length of the clamping rod 72. Sputum core (see Figure 7).

The guiding rod 74 is mounted on the top edge of the pen holder 71 and sleeved on the small diameter portion 721, and is detachably connected to the continuous pen segment 41. The guiding core rod 74 has one on the pushing surface. a side cap portion 741 above the 731, a plug portion 742 connecting the side cap portion 741 and extending along the axis line 711 of the sheath 71, and a portion between the side cap portion 741 and the insert portion 742 and being engaged The limit block 411 of the pen segment 41 of the pen segment 41 defines a retaining block 743 and forms a refill channel 740 that communicates with the sandwich rod 72. The side cap portion 741 can block the sliding member 73 from being disengaged from the pen holder 71, and has two upper fitting holes 744 respectively for the upper convex 412 to be embedded, and two for the lower convex lobes respectively. The lower insertion hole 745 embedded in the 712 can stabilize the connection between the guide rod 74 and the pen holder 71 and the continuous pen segment 41 by using the corresponding convex embedded structure. This embodiment The insert portion 742 has an upper insertion portion 746 detachably inserted upwardly into the slot 410, a lower insertion portion 747 detachably inserted downwardly from the pen holder 71, and a lower insertion portion 747 The convex waist portion 748 between the 746 and the lower insertion portion 747 and abutting against the top edge of the pen 71 has a shape that is more prominent outward than the upper insertion portion 746 and the lower insertion portion 747, and can be used by the user. It is convenient to clamp the guiding core rod 74 and pull out the connecting pen segment 41. In the implementation of the present invention, the coupling manner is not limited to the insertion. For example, the inserting portion 742 can also be screwed together with the continuous pen segment 41 and The pen holders 71 are combined. The design of the limiting block 743 is embedded in the limiting slot 411, so that the guiding rod 74 cannot rotate relative to the continuous segment 41.

The leg 3 and the foot 4 can be coupled to each other in a retracted position and a deployed position. Referring to FIG. 1 and FIG. 4, in the folding position, the leg 3 and the foot 4 are close to each other, and the side of the leg 4 facing the leg 3 is a groove 311 buried in the extension rod 31. The sheath 5 can be disposed from the bottom to the top of the leg 3 and the leg 4 away from the end of the grip handle 2. The sheath 5 of the preferred embodiment is designed as a pen cover, so the sheath 5 The present compass can display the shape of the pen in the folding position, which is convenient for carrying and storing. In addition, the sheath 5 shields the needle 32 and the core portion 723 to prevent other objects from being stabbed or stabbed. It is also possible to protect the needle 32 from being dull by a hard object. Referring to Figures 1 and 5, in the deployed position, the leg 3 and the foot 4 are at an angle to each other.

When the compass is used, the sliding member 73 is slid to push the core rod 72 to core, and then the holding handle 2 is gripped and the leg 3 and the foot 4 are adjusted to the deployed position. The needle 32 of the foot 3 is the center of the circle, and then the handle is rotated Holding the handle 2, the automatic pencil unit 7 of the pen 4 draws a circular arc pattern. Since the slider 73 is attached to the side of the sheath 71, unlike the conventional design, it is necessary to deviate from the axial line 711 of the sheath 71 to be pressed, so that the volume of the compass can be reduced.

Since the core guiding rod 74 of the automatic pencil unit 7 is designed to be detachably coupled to the continuous pen segment 41, when the refill 11 is to be added to the mechanical pencil unit 7, the guiding rod 74 is only required to be moved away. The direction of the holding handle 2 is pulled away, the mechanical pencil unit 7 can be detached from the continuous pen segment 41, and then the refill 11 is inserted into the refill channel 740 of the guiding core rod 74, from which the refill 11 The refill passage 740 slides into the sandwich rod 72, and finally the mechanical pencil unit 7 is inserted into the continuous pen segment 41. Alternatively, the guiding rod 74 can be connected to the continuous pen segment 41, and the pen holder 71 can be pulled away from the guiding rod 74, and then the refill 11 can be inserted into the clamping rod 72, and then the pen 71 can be connected. The guide core 74 is returned.

Referring to FIG. 3 and FIG. 6, when the mechanical pencil unit 7 is detached from the continuous pen segment 41, it can be used alone as a mechanical pencil. Of course, the mechanical pencil unit 7 can also be manufactured and sold separately, and can be used as a separate writing instrument. The characteristics of the sliding core can be distinguished from the general automatic pencil on the market, so it is not necessary to limit it to a compass. One of the constituent elements, the guiding core 74 does not have to have the upper inserting hole 744, the upper inserting section 746 and the configuration of the limiting retaining block 743, and the refill passage 740 is not required to prevent the refill from falling out.

In summary, the novel automatic pencil unit 7 and the compass provided with the mechanical pencil unit are mounted on the side of the pen holder 71 by the sliding member 73, and the sliding member 73 is parallel to the axis 711. The upward sliding mode can reduce the volume of the mechanical pencil unit 7, so that the compass is easy to receive, The design of the sheath 5 also has the effect of converting the compass into the shape of the pen, making the compass easy to carry, thus achieving the creative purpose of the novel.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent.
