Device and method suitable for on-orbit article transfer of spacecraft

The invention discloses a device and method suitable for on-orbit article transfer of a spacecraft. The device comprises a connecting rod, a first limiting sliding rail, a second limiting sliding rail, a capturing mechanism and a motor. One end of the connecting rod is fixedly connected with the capturing mechanism, and the other end of the connecting rod is limited in the second limiting sliding rail and moves along the second limiting sliding rail. A motor is arranged in the middle of the connecting rod for driving the connecting rod to rotate; the motor is limited in the first limiting sliding rail and drives the connecting rod to move along the first sliding rail; track curves of the first limiting slide rail and the second limiting slide rail are designed according to a set moving track of a transferred object; a capturing point is arranged on a transferred object, the connecting rod captures the capturing point through the capturing mechanism, and the object is transferred according to a set moving trac
