3. The device for filling in standardized answer sheets of claim 1, wherein the rotating assembly further comprises a plurality of plectrums and a plurality of one-way torsion springs;

the plectrum passes through one-way torsion spring rotate install in the blade is kept away from the one end of drive shaft, the plectrum has rotational position and reset position, when the plectrum is located reset position, the extending direction of plectrum is the same with the corresponding extending direction of blade, when the plectrum is located rotational position, one-way torsion spring takes place to buckle, just the plectrum is located blade one side, so that the depression bar is followed the plectrum outside passes through, works as when the depression bar is kept away from when the plectrum, the plectrum because one-way torsion spring's elasticity reset action by rotational position moves to reset position.

4. The device for applying a standardized answer sheet according to claim 3, wherein the pressing rod is perpendicular to the driving shaft, a protrusion is convexly provided on one side of the pressing rod facing the pick, the pressing rod has a moving stroke along the extending direction of the pressing rod, and the protrusion of the pressing rod interferes with the pick in the moving stroke;

5. The device according to claim 4, further comprising a compression spring, wherein the extension directions of said compression bar and said compression spring are the same, one end of said compression bar, which is far away from said second notch, is provided with a limiting groove, the notch of which faces away from said second notch, said compression spring is located in said limiting groove, and one end of said compression spring, which is far away from said second notch, is fixed to the inner side wall of said housing.

6. The device for filling in standardized answer sheets according to claim 4, wherein the inside wall of the shell is provided with a plurality of guide blocks which are protruded inwards, and the guide blocks are respectively arranged at two sides of the compression bar so as to limit the compression bar at two sides; and/or the presence of a gas in the atmosphere,

the shell inside wall is equipped with the stopper towards the interior arch, the stopper with the depression bar is relative, in order to right the activity of depression bar in extending direction carries on spacingly.

7. The device for filling in standardized answer sheets according to claim 1, wherein a recycling bin is provided in the housing, the recycling bin is in an upward opening arrangement, and the recycling bin is located below the driven wheel so that the upper base band falls into the recycling bin.
