Detailed Description
Referring to fig. 1 to 8, the pedal control device of the sewing machine includes a pedal control box 1 and a pressing rod 2. Two spring structures and other existing components are also included.
The pedal control box 1 has an integrally curved movable cavity 11 for the pressing rod therein, and a part of the pressing plate 2 is reciprocated by the pedal at this position. A shutter platform 12 is arranged beside the pressure lever movable cavity 11 to make the bottom of the pressure lever movable cavity 11 in a closed state, and the closed state can make the foreign matters enter the control box 1 as little as possible. Both sides of the door stopping platform 122 can adopt an arc design. The other side of the pressure lever movable cavity 11 is provided with a pressure lever extending movable opening 13, and one end of the torsion spring 4 is extruded by one head position of the pressure lever 2 at the position of the pressure lever extending movable opening 13 to realize the actions of half rear stepping on and lifting the pressure foot and full rear stepping on and cutting paper. The shutter platform 12 has control panel fixing members 14 on both sides thereof, the control panel fixing members 14 are integrally formed in a cylindrical structure, the control panel fixing members 14 are formed at corresponding heights, preferably at the same horizontal plane, with the shutter platform 12, and the control panel fixing members 14 are used for fixing the control panel 5 in both left and right directions.
