[0002] As an accessory of the sewing machine, the sewing machine edge stopper is used to facilitate the positioning of the distance between the needle line position and the outer edge of the processed object when the sewing machine is processing, and some sewing machines need two different sewing margins when processing the same object. For example, when sewing a rectangular perimeter, the sewing margins required for the two long sides are inconsistent with the sewing margins required for the two wide sides. Although the traditional adjustable sewing machine edge stopper can also achieve two different sewing margins adjustment, but this adjustment speed is still too slow, affecting work efficiency

The invention discloses a sewing machine positioning and edge-distance adjusting device. The sewing machine positioning and edge-distance adjusting device is simple in structure, capable of rapidly switching two different sewing edge distances and high in sewing processing efficiency. The sewing machine positioning and edge-distance adjusting device comprises a fixed base, a first positioning and edge-distance adjusting plate and a second positioning and edge-distance adjusting plate; the first positioning and edge-distance adjusting plate is connected to the fixed base through a first rotating shaft, and the first positioning and edge-distance adjusting plate comprises a first positioning and edge-distance adjusting foot, a first adjusting device and a first connecting plate; the first positioning and edge-distance adjusting foot is connected to the first connecting plate through the first adjusting device, and front, back, left and right position adjustment is achieved through the first adjusting device; the first connecting plate is fixed to the first rotating shaft and turns over up and down along with the first rotating shaft, and the second positioning and edge-distance adjusting plate is connected to the fixed base through a second rotating shaft; the second positioning and edge-distance adjusting plate comprises a second positioning and edge-distance adjusting foot, a second adjusting device and a second connecting plate; the second positioning and edge-distance adjusting foot is connected to the second connecting plate through the second adjusting device; front, back, left and right position adjustment is achieved through the second adjusting device; and the second connecting plate is fixed to the second rotating shaft and turns over up and down along with the second rotating shaft.
Description
technical field [0001] The invention relates to a sewing machine edge rest. Background technique [0002] As an accessory of the sewing machine, the sewing machine edge stopper is used to facilitate the positioning of the distance between the needle line position and the outer edge of the processed object when the sewing machine is processing, and some sewing machines need two different sewing margins when processing the same object. For example, when sewing a rectangular perimeter, the sewing margins required for the two long sides are inconsistent with the sewing margins required for the two wide sides. Although the traditional adjustable sewing machine edge stopper can also achieve two different sewing margins Adjustment, but this adjustment speed is still too slow, affecting work efficiency. Contents of the invention [0003] The invention provides a sewing machine edge stopper, which has the advantages of simple structure, fast switching of two different sewing margi...
