[0002] As a common school supply, compasses usually only have the function of drawing circles. When studying, students not only need to carry compasses, but also need to carry tools such as rulers and protractors.

[0003] That is, the traditional compass has a relatively simple function. Utility Model Content

[0004] Based on this, it is necessary to provide a compass with diversified functions.

[0005] A compass comprises a main body shell, a first compass foot, a second compass foot, a driving member, a displacement sensor, a control module and a display;

[0009] The first compass foot rotates relative to the main housing, thereby driving the driving member to move relative to the control module. The displacement sensor is used to monitor the movement of the driving member and send the monitoring result to the control module. The control module is used to control the corresponding display of the display according to the monitoring result.

[0010] In one embodiment, the displacement sensor includes a first grid disposed on the driving member and a second grid disposed on the control module.

[0022] One end of the locking member passes through the main body shell and is disposed inside the main body shell, and the locking member is threadedly connected to the main body shell;

[0023] When the locking member moves to the locking position, one end of the locking member drives the sliding member to slide along the limiting sliding groove, thereby making the locking member abut against the sliding member, and at the same time making the sliding member abut against the driving member.

[0024] In one embodiment, the driving member is fan-shaped, and the sliding member is provided with a receiving groove matching the driving member;

[0025] The driving member is stacked on the receiving groove, and when the locking member moves to the locking position, the driving member abuts against the side wall of the receiving groove;
