Therefore, there are many narrow spaces on the aircraft body. These narrow spaces are narrow in width but large in depth. Ordinary screw installation tools are difficult to operate. Due to the large depth, it is impossible to accurately determine the position of the screw or screw hole.

[0020] 2. When the screw needs to be removed, the screw head is raised. Turn the mounting tube, and the mounting tube drives the transmission gear to engage with the transmission rack. When the top ball moves to the screw head that needs to be installed, the top ball is pushed up by the screw head, and the top ball drives the push rod to move upward. The push rod pushes the hydraulic oil upward, and the elastic membrane expands. The staff can determine that the top ball coincides with the screw head. Through observation hole one, note the scale b corresponding to observation hole one, and then turn the mounting tube. The mounting tube drives the transmission gear to engage with the transmission rack, and the transmission rack drives the support frame to move, so that observation hole two moves to scale b. At this time, the mounting hole is aligned with the screw head, and then turn the disassembly rod. The disassembly rod moves downward and rotates. The screwdriver head at the lower end of the disassembly rod cooperates with the screw head to remove the screw. BRIEF DESCRIPTION OF THE DRAWINGS
