Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a novel printing paper limiting structure and a micro printer. Background Art

[0002] Generally, in order to meet the usage requirements of printing papers with different widths, a slider for paper width limitation is installed on the paper guiding bracket of a general micro printer. At present, most on the market use a rack and a gear for the sliding of the slider; in addition, there is also a paper limiting function achieved through a paper limiting knob. However, for the existing screw locking structure, in order to facilitate the adjustment of the position of the paper limiting knob in the sliding opening, the screw is usually not locked tightly, which easily causes the paper limiting knob to shake during use; and when the screw is locked tightly, a tool is required to loosen the screw every time the position of the paper limiting knob is adjusted, resulting in inconvenient use. Chinese Patent with publication number CN213676059U discloses a compact ticket printer, which fixes the paper limiting knob by screwing and locking a sliding block, and through a limiting member and damping bumps, the damping bumps generate frictional force with the inner wall of the housing, improving the feel of turning. To a certain extent, the problem of the paper limiting knob shaking is solved, but the structure with the limiting member and damping bumps arranged on one side causes unbalanced forces on both sides of the paper limiting knob, and it is easy to have a jamming phenomenon during use, resulting in inconvenient use.
