In order to keep the linkage in contact with the cam 3 at all times to effect the reciprocating movement of the foot pad 15, an elastic member 11 is connected between the linkage and the housing 1.

In the present embodiment, the link mechanism includes the driving lever 4, the first rotating arm 12, and the second rotating arm 14, and the elastic member 11 can keep the driving lever 4 in contact with the cam 3 at all times. One end of the first rotating arm 12 is hinged to the driving rod 4 through a first rotating shaft 6, the other end of the first rotating arm is hinged to one end of the foot pad 15 through a fourth rotating shaft 13, one end of the second rotating arm 14 is hinged to the shell 1 through a second rotating shaft 8, and the other end of the second rotating arm is hinged to the other end of the foot pad 15 through a fifth rotating shaft 16. By rotating the cam 3, the driving rod 4 can move in the horizontal direction, so that the first rotating arm 12 and the second rotating arm 14 can be driven to rotate, and the foot pad 15 can be driven to move towards or away from the housing 1.

As shown in fig. 3, when the cam 3 is in the first state, the distance between the foot pad 15 and the housing 1 is the minimum, which is the initial state of the electronic device; as shown in fig. 5 and 6, when the cam 3 is in the second state, the distance between the foot pad 15 and the housing 1 is the largest, and the electronic device is in a lifted state.

Specifically, the operating principle of the driving device is as follows: in the process that the cam 3 rotates from the first state to the second state, the cam 3 can push the driving rod 4 to move, the elastic component 11 extends, and the driving rod 4 pushes the first rotating arm 12 to rotate, so that the first rotating arm 12 and the second rotating arm 14 simultaneously push the foot pad 15 to move away from the shell 1;
