1. An anti-skipping device, comprising:
a pair of fixed bases symmetrically disposed on both sides, the pair of the fixed bases having slide rails extending along a longitudinal direction and having two side walls facing each other along a transverse direction perpendicular to the longitudinal direction;
an extension member movably inserted on the fixed bases and being slidable along the slide rails to move between an extended position and a retracted position in respect to the fixed bases;
a locking member configured to engage with the fixed bases and the extension member, so as to lock a position of the extension member in respect to the fixed bases; and
a crossbar disposed between the two side walls to prevent the two side walls from being laterally displaced from each other.
