[0022] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a compass device includes a housing 1, and a bracket 2, which is rotatably installed in the housing, the top end surface of the bracket is provided with a support 21, and the bottom end surface is provided with a counterweight 22; a pointing plate 3, which is rotatably installed on the support along its own axis and is equipped with a magnet 31. Figure 3 For example, the bracket can rotate forward and backward, the direction plate is installed on the pillar and can rotate, and the magnet is installed on the direction plate to achieve steering when the direction changes. In addition, the rotation axis of the bracket can be installed at the center of the inner wall of the shell, that is, the extension line of the rotation axis can pass through the center of the shell, and the shell can be made into a spherical shape. If necessary, it can be filled with liquid, such as oil. Further, in order to maximize the use of the space in the shell, there is a cross section in which the rotation axis of the bracket passes through the midpoint of the cross section of the shell, and the counterweight is used to maintain the level after rotation so that the pillar faces upward.

[0023] In this embodiment, as shown in the figure, the counterweight block 22 is arranged at the center of the bracket.

[0024] In this embodiment, as shown in the figure, the center of the pointing disk is provided with a rotating shaft 32, and the pillar is provided with an axial hole 25 matched with the rotating shaft. The rotating shaft is provided on the pointing disk to provide support for the rotation of the pointing disk, and the axial hole can be provided on the pillar, and the rotating shaft part extends into the axial hole to achieve matching.

[0025] In this embodiment, as shown in the figure, the shaft hole is an open slot structure provided on the top end surface of the pillar, and the bottom of the shaft is a spherical or needle-shaped structure. The shaft adopts a spherical or needle-shaped structure to better realize rotation and deflection, and the overall floating installation is more flexible.

[0026] In this embodiment, as shown in the figure, the magnet is used to keep the pointing plate horizontal.

[0027] In this embodiment, as shown in the figure, the support comprises a rod body and a platform 211 provided on the top of the rod body, a limiting groove 34 is provided at the center of the pointing disk, part of the platform is provided in the limiting groove and cooperates with the limiting groove to limit the vertical upward direction to prevent the pointing disk from falling out. The platform part is provided in the limiting groove, so that the pointing disk will not fall out from the top, and the bottom will not fall out because it is supported by the rotating shaft, so that the limiting is achieved, and there is a gap between the inner wall of the limiting groove and the outer wall of the platform, so that the pointing disk can swing.

[0028] In this embodiment, as shown in the figure, the pointing plate is provided with a slot 33, and the magnet is installed in the slot. It is easy to install and also acts as a counterweight. The magnet is provided on both sides of the limit slot, and two magnets can be provided on both sides of the limit slot to help maintain balance.

[0029] In this embodiment, as shown in the figure, there is a gap between the circumferential inner wall of the limiting groove and the circumferential outer wall of the platform.

[0031] In this embodiment, as shown in the figure, the platform is a frustum-shaped structure with a small bottom and a large top. The large diameter part of the platform is blocked by the limit groove so that the pointing plate cannot fall out, and the small diameter part of the platform is arranged in the limit groove so that the pointing plate can swing to a certain extent.

[0032] In this embodiment, as shown in the figure, the pointing plate is provided with an arch bridge 35, and the rotating shaft is installed on the arch bridge. The rotating shaft is arranged just above the pillar.
