On 312 inner face, one end of the interior pawl 313 is hinged on by axis pin 315 on flywheel disk 31, and other end connection elasticity is even
Fitting 314, the operation principle when the handle 2 for lifting handcart driving device rotates clockwise is as it was noted above, be not repeated;When
Object needs to decline when being promoted to a height, and rotating handle 2 counterclockwise allows object slowly to decline, if human negligence at this time, leads
Cause handle 2 out of hand, if torsional spring above-mentioned 18 still can not when attaching nut 17 and main shaft 11 generate relative rotation,
11 brake apparatus of original main shaft fails, and main shaft 11 can drive attaching nut 17 to do acceleration rotation counterclockwise, while band
It is dynamic that acceleration rotation counterclockwise is done with 14 rigidly connected flywheel disk 31 of attaching nut, since interior pawl 313 is to pass through tension spring
314 are constrained on flywheel disk 31, but the acceleration counterclockwise of flywheel disk 31 rotate so that in pawl 313 generate it is outside
Centrifugal force, the centrifugal force are more than flexible connector(Tension spring)312 inside tightening forces, cause interior pawl 313 to swing out, and with
