Rotating, connecting rod drives fork III to rotate clockwise around the shaft, the fixing the rightest pendulum of post hook and slot, Gu
Fixed column and fixing post hook and slot depart from, and the left end of press frame loses constraint, the pushing away of piston of cylinder
Under power effect, press frame I rotates clockwise around the shaft；Enter when curved rod turns to support column
After in groove, curved rod stops operating, and support column is at the axial connecting line of rotating shaft VI and rotating shaft II
Left side, cylinder is provided support force, cylinder piston to continue to stretch out until completing all to live by support column
Plug stroke；
(2) press frame puts down process: cylinder is exitted, and piston is retracted, cylinder piston pulling force and
Under the effect of gravity, press frame I rotates counterclockwise around the shaft, when going to rotating shaft II and rotating shaft
When the line of I is parallel with paper feeding platform plane, piston continues retraction, curved rod V inverse time around the shaft
Pin rotates, and connecting rod drives fork III to rotate counterclockwise around the shaft, fixing post hook and slot left swing therewith,
The fixing post fallen enters in fixing post hook and slot.
The present invention is advantageous in that: (1) simple in construction, easily manufactured, with low cost.(2)
When press frame lifts, after support column enters in the groove position of the groove in curved rod, support column is turning
The left side of the axial connecting line of axle VI and rotating shaft II, forms dead point and supports, according to dead point principle, pressure
Paper frame will not fall down under external force, reduces potential safety hazard.(3) mounting means is simple, behaviour
Facilitate.(4) labor intensity is little, and safety coefficient is high.
