Reinforcement cage extrusion sleeve connecting device in cast-in-place pile construction

The utility model relates to the technical field of reinforcement cage connection in cast-in-place pile construction, in particular to a reinforcement cage extrusion sleeve connecting device in cast-in-place pile construction. The reinforcement cage extrusion sleeve connecting device in cast-in-place pile construction comprises an extrusion barrel and a lifting assembly used for lifting the extrusion barrel, a fixed clamping plate and a movable clamping plate are arranged in an extrusion cavity formed in the extrusion barrel, and a hydraulic cylinder used for driving the movable clamping plate and the fixed clamping plate to be closed is installed at the bottom of the extrusion barrel; and the extrusion cylinder is erected on the lifting assembly. According to the reinforcement cage extrusion sleeve connecting device in the cast-in-place pile construction, the driving motor is started to drive the threaded rod to rotate, the threaded connecting base is limited by the limiting rod, and therefore the threaded c
