The invention relates to a paper roll clamp with an improved pin shaft fixing manner. A pin shaft fixing manner is improved, and an oil cylinder pin shaft comprises a plunger rod and a positioning screw; and one side of the plunger rod is provided with grooves with triangular sections, the plunger rod penetrates a front base plate assembly and one end of an oil cylinder, and two positioning screws are screwed into the back side of the front base plate assembly to abut against the grooves in the two ends of the plunger rod. The paper roll clamp has the beneficial effects that compared with an old pin shaft cover fixing mode adopted in an old paper roll clamp, a pin shaft cover is omitted, 30 mm is reduced from the width in the coaxial direction, only a long arm assembly and a short arm assembly need to be designed to be thinner, a large amount of space is saved, interference can be avoided, and the cost can be greatly reduced; and in addition, the weight of an overall paper roll is reduced, wider motion space is provided for the long arm assembly and the short arm assembly, and the cost is reduced.
