Buffer on pulling force machine

The utility model relates to a pulling force machine technical field, in particular to buffer on pulling force machine, including controlling two buffer storage wares, the both sides of buffer storageware install the iron bar, the lower part of iron bar pass the buffer storage ware, the upper portion of iron bar install on the equipment frame of pulling force machine hoist and mount, the side ofbuffer storage ware be equipped with the switch, the on -off control buffer storage ware in two blocks of magnet attraction and open, the iron bar on be equipped with the screw thread, the iron bar passes behind the buffer storage ware fixedly with the nut, the upper portion of iron bar is also fixed on the equipment frame of pulling force machine hoist and mount through the nut. The beneficial effects of the utility model are that: after increasing buffer, the pulling force function enough effectively prevents because of the underriding strength that gravity and drop brought, has solved the face crease that the underr
