Abstract
An electric stapler is provided, which includes a machine base, and the machine base is provided with a bookbinding frame and a nail pressing mechanism. The nail pressing mechanism includes a nail pressing gear, a motor, and a plurality of transmission gears. The nail pressing gear is rotatably connected to the machine base through a connection shaft, and the motor drives the nail pressing gear to rotate through the plurality of transmission gears. The machine base is provided with long holes on left and right sides, and the connection shaft can move up and down in the long holes. The machine base is further provided with an auxiliary nail pressing component, which can push down against the connection shaft.
Claims8
An electric stapler, comprising a machine base, wherein the machine base is provided with a bookbinding frame and a nail pressing mechanism;
- wherein the nail pressing mechanism comprises a nail pressing gear, a motor, and a plurality of transmission gears, each of the plurality of transmission gears being rotatably connected to the machine base;
- wherein the nail pressing gear is rotatably connected to the machine base through a connection shaft, and the motor drives the nail pressing gear to rotate through the plurality of transmission gears, so that a roller on the nail pressing gear presses down against the bookbinding frame;
- wherein the machine base is provided with long holes on left and right sides of the machine base, the long holes being extended in an up-down direction;
- wherein two ends of the connection shaft are inserted into corresponding ones of the long holes, and the connection shaft is capable of moving up and down in the long holes;
- wherein the connection shaft and the nail pressing gear are capable of moving up and down synchronously;
- wherein a travel stroke of the connection shaft moving up and down in the long holes is 4.0 mm to 5.0 mm;
- wherein the machine base is further provided with an auxiliary nail pressing component, and the auxiliary nail pressing component is capable of pushing down on the connection shaft to drive the nail pressing gear to move down and cause the roller to be pressed down on the bookbinding frame;
- wherein a tooth height of the nail pressing gear is 2.0 mm to 2.5 mm;
- wherein a tooth height of one of the transmission gears that is closest to the nail pressing gear is 2.0 mm to 2.5 mm;
- and
- wherein within a travel stroke range of the connection shaft, when the nail pressing gear is moved up and down, the nail pressing gear maintains a transmission connection with the one of the transmission gears that is closest to the nail pressing gear;
- wherein a distance b2 between a centerline of the roller and a centerline of the connection shaft is 10 mm to 12 mm;
- wherein a horizontal distance b1 between the centerline of the connection shaft and a centerline of one of the transmission gears that is closest to the nail pressing gear is 28 mm to 29 mm.
