Abstract
A novel quick fastening device comprises a base, an energy storage medium, an impact unit and a driving mechanism; the driving mechanism includes an annular gear, a driving shaft, a crank, a planet gear; the planet gear is placed in the annular gear and engaging with the annular gear, so that it can implement revolution against annular gear, the planet gear implements rotation at the upper end of crank; a clamp shaft for connecting the impact unit is located in the upper end of the connecting rod, the lower end of driving shaft is connected to the rotating energy release unit; the annular gear-planet gear structure to implement the conversion of rotary motion into reciprocating motion, the kinematic trajectory of clamp shaft on the connecting rod approximates to a straight line, so as to reduce the kinetic friction force of load to the maximum extent to avoid wear.
