Embodiment

Consult Fig. 1, Fig. 2, comprise in the preferred embodiment of compass of the present utility model: a base plate 1, a north arrow unit 2, an aiming unit 3, a cover plate 4, positioning piece 5, and a spigot 6.

This base plate 1 has one first pivot part 11 that is formed on a rear end, one first scribe mark 12, one second scribe mark 13 and one the 3rd scribe mark 14 that is formed on two avris and a preceding avris, and is formed on two ear seats 15 of an end face and a contiguous front end.This first pivot part 11 has a plurality of pivot ears 111 of arranging along an axis X direction.

This north arrow unit 2 is arranged on this base plate 1, and can indicate the orientation.

A sight hole 32, a magnifier 33 and a buckle 34 that this aiming unit 3 has a vane 31, is formed on this vane 31 and arranges in regular turn from top to bottom.This vane 31 is with an end and this base plate 1 ear seat 15 pivots knot, can be in a primary importance L1 (consulting Fig. 2) who repeatedly puts on this north arrow unit 2, and the displacement between a second place L2 (consulting Fig. 3) of these north arrow unit 2 one sides that stands.When this vane 31 was positioned at this second place L2 (consulting Fig. 3), this buckle 34 was to be emerging on this base plate 1.

This cover plate 4 has one second pivot part 41 that is formed on a rear end, be formed on two avris and one first scribe mark 42 and one second scribe mark 43 that can be connected with this base plate 1 first,

second scribe mark

12,13, be formed on avris before one the 4th scribe mark 44, be formed on one light tight 45 and a boresight 46 of middle part, and run through a catching groove 47 of an end face and a bottom surface and relative this buckle 34.This second pivot part 41 have along this axis direction arrange and with the involutory a plurality of pivot ears 411 of aforementioned pivot ear 11 1.

This keeper 5 has and is contained in these first,

second pivot part

11,41 111,411 in adjacent pivot ears and general ringwise a plurality of anti-slip sections 51.Aforementioned anti-slip section 51 this first,

second pivot part

11,41 relatively produces blockage effect.

This spigot 6 is to run through this base plate 1, the pivot ear 111,411 of these cover plate 4 first,

second pivot parts

11,41 and the anti-slip section 51 of this keeper 5 along this axis X direction, makes this cover plate 4 become one with this base plate 1 pivot, and can extend relatively.

Consult Fig. 3, during use, 4 one-tenth 180 degree of this base plate 1 and this cover plate extend earlier, make this base plate 1 and this cover plate 4 under the state that docks, this is first years old,

second scribe mark

12,13,42,43 also are connected mutually, at this moment, need only on map, find out the position at present place earlier, and mark the destination, just the utility model can be flat on the map, with this

first scribe mark

12,42, or this

second scribe mark

13,43, or the 3rd scribe mark 14, or the 4th scribe mark 44, measure the location distance to destination, on map, measure the orientation angles of destination with this north arrow unit 2 again.

Consult Fig. 4, Fig. 5, during use, also can be by the blockage effect of these keeper 5 anti-slip sections 51, making this cover plate 4 be centre of gyration turn with this base plate 1 with this spigot 6, and is positioned at arbitrarily angledly, reaches the purpose of adjusting this base plate 1 and these cover plate 4 orientation angles.

Whereby, the utility model is placed on hand, adjust the angle of this base plate 1 and this cover plate 4 arbitrarily, and the person's of being used eyes focal length, between primary importance L1 and second place L3, adjust the angle of this vane 31, the orientation angles that just can utilize the magnifier 33 on this vane 31 to read this north arrow unit 2.At this moment, need only make sight hole 32 on simple eye sight line and this vane 31, the boresight 46 on this cover plate 4 in line, extend forward again and find out on the destination significantly subject matter, just can arrive at the destination.

Consult Fig. 6, after finishing using, need only be earlier with the primary importance L1 that this vane 31 is positioned at repeatedly put on this north arrow unit 2, cover this base plate 1 and this cover plate 4 again, this cover plate 4 is fastened mutually with the buckle 34 on this catching groove 47 and this vane 31, whereby, fasten this cover plate 4 and this vane 31, this north arrow unit 2 and this aiming unit 3 folders are protected 4 of this base plate 1 and this cover plates, and reduced volume and being easy to carry.

According to the above as can be known, compass of the present utility model has following advantage and effect:

The utility model can be by the blockage effect of this keeper 5, make this base plate 1 be positioned at any angle position with this cover plate 4, and can utilize this buckle 34 and the fastening of this catching groove 47 to concern, locating effect when strengthening this base plate 1 and coinciding with this cover plate 4, whereby, promote functions of use, and convenience and practicality on using.
