[0028] Combination Figure 1 , Figure 2 and Figure 3 The utility model discloses a compass of one embodiment, including a main body shell 10, a first compass foot 20, a second compass foot 30 and a hydraulic display device 40.

[0029] One end of the first compass foot 20 is rotatably connected to the main housing 10 .

[0030] A scale 101 is provided on one side of the main housing 10 .

[0031] The hydraulic pressure display device 40 includes a liquid storage member 42 storing liquid and a liquid flow channel 44 communicating with the liquid storage member 42 and corresponding to the scale 101 .

[0032] The first compass foot 20 rotates relative to the main housing 10 , thereby driving the liquid in the liquid storage part 42 to flow along the liquid flow channel 44 , and the opening amplitude of the first compass foot 20 relative to the second compass foot 30 matches the scale 101 corresponding to the position where the liquid stays in the liquid flow channel 44 .

[0033] The first compass foot 20 of the compass rotates relative to the main housing 10, and the opening range of the first compass foot 20 relative to the second compass foot 30 matches the scale 101 corresponding to the position where the liquid stays in the liquid flow channel 44, so that the compass has other functions.

[0034] Compared with traditional compasses, the compasses of the utility model are more diversified.

[0035] Generally speaking, in order to make the display more obvious, the liquid is usually selected to be a brighter color, such as red, orange, etc.

[0036] Preferably, combined Figure 4 In this embodiment, the hydraulic display device 40 also includes a piston 46 matched with the liquid storage member 42, and the first compass foot 20 drives the piston 46 to move relative to the liquid storage member 42, thereby driving the liquid in the liquid storage member 42 to flow along the liquid flow channel 44.

[0037] More preferably, combined with Figure 4 In this embodiment, the piston 46 includes a driving portion 462 connected to the first compass foot 20.

At this time, the opening range of the first compass foot 20 relative to the second compass foot 30 matches the distance scale corresponding to the position where the liquid stays in the liquid flow channel 44, so that the compass of the utility model also has the function of measuring length, and can also draw a circle of the desired size without the need for a ruler.

[0045] In another embodiment, the scale 101 is an angle scale. At this time, the opening range of the first compass foot 20 relative to the second compass foot 30 matches the angle scale corresponding to the position where the liquid stays in the liquid flow channel 44, so that the compass of the utility model also has the function of measuring angles.

[0046] Preferably, in this embodiment, the scale 101 and the liquid flow channel 44 are both annular.
