Take spacing overspeed device tensioner

The utility model relates to a take spacing overspeed device tensioner with solve among the prior art bilateral safe pliers and overspeed governor go upward the linkage in experimental the tensioningwheel carrier can be knocked the guide rail and impaired technical problem to lifting when drawing take -up pulley or guard shield. It is right the utility model discloses going upward when experimentlinkage, resulting in the tensioning wheel carrier to be carried when drawing because of the linkage effect who goes upward safety tongs and overspeed governor is not good, the tensioning wheel carrier overturns on can following the axis of rotation aline between its and the installing support. Interval between bulge and the installing support outer end makes the take -up pulley shelf energy upwards rotate a constant angle degree, when the tensioning wheel carrier rotate surpass establish the constant angle degree after, bulge on the tensioning wheel carrier can be by the outer end block of installing support, and thi
