Abstract
The utility model relates to a device for quickly lifting a no-load hydraulic jack by mechanical operation, which is characterized in that: a driving piece is pivoted on a lifting arm shaft (or shaft hole sleeve) as a rotary fulcrum. The lifting arm shaft can rotate with the driving piece when the jack is in no-load state, and the other end of the driving piece pushes the piston rod spindle enabling the piston rod to extend outwards, thus to drive the lifting arm of the jack to lift quickly and contact the standby position of the heavy object. The driving piece can be designed as a connecting rod or a handle for mechanical operation. The utility model has an advantage of quickly lifting a no-load hydraulic jack.
