1. An apparatus, comprising:
a housing comprising a first shell member and a second shell member;
a driving mechanism operable to expand and/or contract the housing, the driving mechanism comprising an axle having a longitudinal axis;
a torque transfer mechanism operable to transfer torque to the driving mechanism, the torque transfer mechanism comprising a rotation-transmitting member coupled to the axle and a driving member configured to receive torque applied from a direction non-parallel to the longitudinal axis of the axle and drive the rotation-transmitting member, whereby application of torque to the driving member allows the rotation-transmitting member and the axle to rotate about the longitudinal axis, causing the first shell member and the second shell member of the housing to move relative each other in a direction non-parallel to the longitudinal axis of the axle to allow the first shell member and the second shell member of the housing to open and/or close with substantially equal distance along a side generally in parallel with the longitudinal axis of the axle.
