An improved structure of a screwdriver tip comprising a screwdriver shaft and a screwdriver tip, a circular hole being provided on the top face of the shaft body of the screwdriver shaft, closing to the front end thereof, and the shaft body being hollow for the insertion of the rod of the screwdriver tip, a cavity of an appropriate depth being provided at the rear end top face of the rod of the screwdriver tip, the cavity corresponding to the circular hole of the shaft body of the screwdriver, allowing the mounting of an elastic pad body, characterized in that the center of the top face of the elastic pad body is provided downwardly with a mounting hole for the insertion rod located below the bottom portion of the protruded stopper, the top portion of the insertion rod of the protruded stopper is extended to mount with a circular body having the top portion being extended with a circular protruded block having a recessed hole, the protruded stopper and the elastic pad body are insertably and securely connected and the elastic pad body is mounted at the cavity hole of the rod of the screwdriver tip such that the circular protruded block is extended to the exterior of the cavity hole, such that when the rod of the screwdriver tip is inserted into the shaft of the screwdriver, a pointed member is urged at the recessed hole of the circular protruded block to urge the elastic pad body to retract, the retraction of the protruded stopper allows the top face of the circular protruded block to smoothly push to the interior of the rod body, and when the circular protruded block is pushed to the circular hole of the shaft body, the elastic pad body urges upward the protruded block is extended into the circular hole, and the circular body of the protruded stopper is exactly urged the inner face of the circular hole to stop the rod of the screwdriver tip from continuously inserted with the shaft body of the screwdriver shaft, and the screwdriver tip is fully insertably connected to the front end of the shaft body of the screwdriver shaft, thereby allowing the interchangeable of screwdriver tips.
