The invention provides a cam type port connection device for a computer extending screen. The cam type port connection device comprises a pin shell, and is characterized in that a pin is arranged in the pin shell, and is connected with a circuit board; a cam is arranged on the lower side of the circuit board; the axis of the cam is connected with a center shaft; one end of the center shaft is connected with a handle, and a catch is arranged at the other end of the center shaft, and is positioned on the outer side of the pin shell; the lower side of the circuit board is connected with one end of a retractile spring; the other end of the retractile spring is connected with the pin shell; and the handle is in threaded connection with a fixing bolt. By the rotation of a rotating shaft, a hub is driven to rotate; under the driving of a common flat key, the cam pushes the circuit board to move upwards, so that the pin is inserted into a computer connection port; and by the adoption of a cam mechanism, the cam type port connection device is simple and compact in structure. The retractile spring is mounted at the lower end of the circuit board; after the cam rotates through the highest point, the retractile spring drives the circuit board to move downwards, so that the pin is separated from the computer connection port; and under the driving of the retractile spring, the circuit board can keep horizontal in a descending process, so that deformation of the pin is avoided.
