An anti-jumping block device comprises a fixed seat which is symmetrically arranged on two sides and is provided with a sliding rail extending in the longitudinal direction and two side walls facing each other in the transverse direction perpendicular to the longitudinal direction; the extension piece is movably inserted into the fixed seat and can slide along the sliding rail, so that the extension piece moves between an extension position and a retraction position relative to the fixed seat; the locking piece is used for connecting the fixed seat and the extension piece so as to lock the position of the extension piece relative to the fixed seat; and the cross rod is arranged between the two side walls and is used for preventing the two side walls from transversally displacing each other.
