Between be provided with supporting device, supporting device include drive link（4）And bearing（5）, bearing（5）Installed in drive link（4）Middle part.
Above-mentioned connecting lever（6）End carry camber, and end connection drive link（4）One end, drive link（4）The other end
With sleeve（3）Connection.
Above-mentioned connecting lever（6）And drive link（4）Band moving sleeve（3）Rotate, bearing（5）Inner ring and drive link（4）It is connected,
Pass through bearing（5）Ball rotate, make drive link（4）While rotation, bearing（5）Outer shroud is remained stationary as.
Above-mentioned circular groove（1）Outside provided with guiding groove（8）, described guiding groove（8）Depth be less than circle
Groove（1）Depth.
The beneficial effects of the utility model are：The utility model can with standard, specification, easily and efficiently complete handcart open
What is closed stops power transmission operation, it is to avoid switch contact burns, it is to avoid fluctuation of the electric arc to line voltage, influences the stabilization of whole system
Property, the device is provided with supporting device, and bearing inner ring is synchronous with drive link, and the ball in the middle of bearing is rotated, and hand-held outer race is not
It is dynamic, the effect in firm crank axle center is reached, is easy to staff's swinging handle to exert a force again, in four inwalls of equipment interconnection square hole
Centre is each to make a call to a circular groove, and the device with pressure ball, ball falls in circular hole, when crank stress, will not slide
It is dynamic, serve the effect of firm hand handle.
