Pressing-in device applied to pressing-in machine for bushing of steering machine

The invention discloses a pressing-in device applied to a pressing-in machine for a bushing of a steering machine. The pressing-in device comprises a rack, a first downwards-pressing piece and a pressing head piece; a support for mounting the steering machine is arranged on the rack; the first downwards-pressing piece is arranged on the rack in an up-and-down gliding manner; the pressing head piece is arranged on the first downwards-pressing piece in an up-and-down gliding manner and extends below the first downwards-pressing piece; and a travel switch for limiting the gliding distance of thepressing head piece relative to the first downwards-pressing piece is further arranged on the pressing head piece. Damage caused by collision of the first downwards-pressing piece with the pressing head piece can be avoided by the aid of the travel switch arranged on the pressing head piece, so that the safety is high. During working of the pressing-in device, the downwards-pressing travel of thepressing head piece and th
