The invention discloses a paper pressing device. The paper pressing device comprises a
machine body and a first cavity formed in the
machine body, wherein left-right symmetrical first sliding groovesare formed in the upper end of the
machine body in a communicating mode; a first transmission shaft positioned between the first sliding grooves and extending up and down is rotatably and cooperatively connected to the inner wall of the top end of the first cavity; a first
bevel gear is arranged at the
tail end of the bottom end of the first transmission shaft; and a track
barrel positioned on theupper end face of the machine body is fixedly connected to the top end of the first transmission shaft; the track
barrel is circumferentially provided with a track groove in a surrounding mode, a limiting block is fixedly connected to the
tail end of the upper end of the track groove, and a guide slide block is connected to the track groove in an abutting mode; and an L-shaped
power block is fixedly connected to the other end of the guide slide block, a second sliding groove with an opening to the left is formed in the left end face of the L-shaped
power block, and an extension rod is connected in the second sliding groove in a sliding fit mode. According to the paper pressing device, the linkage is high, the manual leveling action simulated by a mechanical rod is efficient and sanitary,and multi-directional pressing points ensures that offset does not occur.
