Manual craft cutting machine

A manual craft cutting machine, comprising a housing (1), a template, a press roller, a retainer, a backing plate and a drive mechanism;

• the template including a pair of upper and lower templates, a pattern medium being sandwiched between the upper and lower templates;
• the press roller being composed of a pair of a first press roller (4) and a second press roller (5), the press rollers being disposed axially parallel to each other, two ends of the press roller forming a roller axle (41) or extending in an axial direction of the press roller to form the roller axle (41), the roller axle (41) being confined by the retainer, the backing plate being composed of a pair of backing plates attached to each other and sandwiched between the press rollers, the template being sandwiched between the backing plates;
• characterized in that:
• the retainer comprises a positioning retainer (3) and a sliding retainer, the positioning retainer (3) is tightly connected with the housing (1) and disposed at the two ends of the press roller, the positioning retainer (3) is provided with a slide groove;
• the sliding retainer is inserted in the slide groove and movable along the slide groove, the sliding retainer comprises a first sliding retainer (31) rotatably connected with the first press roller (4) and a second sliding retainer (32) rotatably connected with the second press roller (5);
• the drive mechanism includes a handle (2) and a gear set;
• the gear set includes a speed reduction gear set (6) and a constant speed gear set (7), the speed reduction gear set (6) includes a handle gear (61), a speed reduction gear or the speed reduction gear set (6) to mesh with each other, the handle gear (61) is rotated along with the handle (2), the speed reduction gear is connected with the first press roller (4) or the second press roller (5) to drive one of the two press rollers to rotate;
• the constant speed gear set (7) includes a pair of a first constant speed gear (71) and a second constant speed gear (72) to mesh with each other, the constant speed gears are fixed on the roller axles of the first press roller (4) and the second press roller (5) respectively, when one of the press rollers is driven by the speed reduction gear to rotate, the other press roller is driven by the constant speed gear to rotate at a constant speed;
• the manual craft cutting machine further comprises a press roller spacing adjustment mechanism, the press roller spacing adjustment mechanism comprises a shift adjusting mechanism for adjusting a large spacing between the press rollers and a fine adjustment mechanism for adjusting a fine spacing between the press rollers, the shift adjustment mechanism drives the first sliding retainer (31) to move along the slide groove, the fine adjustment mechanism drives the second sliding retainer (32) to move along the slide groove.
