The plurality of suspension wires 1631 may not only physically connect the fixed member 162 and the movable member 161, but also electrically connect the circuits on the fixed member 162 and the movable member 161. The plurality of suspension wires 1631 in each group of suspension wires can be arranged at intervals, namely, circuit isolation is realized between two adjacent suspension wires 1631 at intervals, and the transmission of power or signals by the plurality of suspension wires 1631 is not influenced.

Alternatively, the elastic member 163 may also include, but is not limited to, various springs. Each elastic member 163 may include one or more bullet-shaped members, and each elastic member 163 may be formed of a plurality of elastic wires in a spiral shape, and in this case, the first end a1 of the elastic member 163 may be an end portion formed by the plurality of elastic wires together, and the second end a2 may be another end portion formed by the plurality of elastic wires together.

The specific structure of the elastic member 163 is not limited in the embodiment of the present application, and any structure of the elastic member 163 that can bear the acting force generated by the movement of the movable member 161 driven by the driving mechanism 120 and can have elastic restoring force is within the scope of the embodiment of the present application.

It is understood that the projection of the first end a1 of each elastic member 163 on the movable member 161 may be staggered from the second end a2 thereof, for example, both may be disposed on different sides of the movable member 161. Each elastic member 163 is connected to one side of the fixed member 162 and the other side of the movable member 161 corresponding to the side. Each elastic member 163 may form a torsion spring structure, and the plurality of elastic members 163 have a larger pulling force on the movable member 161, so that the stability of the movable member 161 may be improved.

It is understood that, here, adjacent may mean that the distance between the first end a1 of the previous elastic member 163 and the second end a2 of the next elastic member 163 may be within a smaller preset range, so that the elastic torsion of the two adjacent elastic members 163 may cover the entire side of the movable member 161, and the stability of the movable member 161 is better.
