[0032] In order to improve the stability of the step-by-step sliding of the guide member 3, the number of the adjusting parts 32 of each guide member 3 is set to two, the limiting structure 4 includes a sliding part 41 whose protrusion corresponds to the adjusting part 32, and the ends of the two adjusting parts 32 pass through the guide opening 22 and are folded and slidably hooked on the corresponding sliding part 41, and the arc-shaped concave-convex end of the adjusting part 32 is provided with a plurality of staggered convex teeth 321 and a plurality of grooves 322, and the sliding part 41 is convexly provided with a limiting tooth 422 adapted to the groove 322. Specifically, the number of the sliding parts 41 is set to four and they are respectively arranged on the front and rear sides of the two guide openings 22; the guide member 3 slides step by step until the limiting tooth 422 is embedded in the corresponding groove 322 and then is positioned. Therefore, the stability of the step-by-step positioning of the adjustment part 32 by the limiting structure 4 is improved through the limiting cooperation between the limiting teeth 422 and the plurality of grooves 322, and the smoothness of the sliding of the limiting teeth 422 into different grooves 322 is improved through the arc-shaped convex teeth 321, thereby improving the adjustment stability and smoothness of the guide member 3.

[0033] In order to improve the adjustment smoothness of the guide member 3, the number of the convex teeth 321 and the groove 322 are set to three and two respectively, and the limiting structure 4 also includes a limiting portion 42 protruding on the sliding portion 41 and corresponding to the adjusting portion 32 respectively, and the limiting portion 42 is recessed in the direction away from the end of the adjusting portion 32 and is provided with a limiting groove 421, and the two ends of the limiting groove 421 are arc-shaped to form two limiting teeth 422, and the groove width of the limiting groove 421 is adapted to the width of the end of the adjusting portion 32; the guide member 3 slides until a limiting tooth 422 slides and fits into a groove 322 or the end of the adjusting portion 32 fits into the limiting groove 421 and is positioned.

This avoids the situation that the two guide parts 31 are attached to the outer wall of the machine body 1 due to excessive adjustment, which makes it difficult to reset. The two guide parts 31 are offset toward the adjacent side, so that under the premise of the same step-by-step sliding distance and the need to avoid the guide parts 31 from abutting the outer wall of the machine body 1, the sliding adjustment distance of the guide parts 31 can be larger, so as to increase the number of adjustment levels to adapt to printing papers of multiple specifications, and improve the adaptability of the guide parts 31.

Specifically, the plurality of anti-slip ribs 23 are extended forward and backward. Thus, the friction between the paper guide part 2 and the printing paper is improved by the provision of the plurality of anti-slip ribs 23, so as to avoid the situation that the printing paper slips during paper feeding and causes the guiding failure of the guide member 3.
