Screw anti-falling equipment for airplane narrow part

Abstract

The invention discloses screw anti-falling equipment for an airplane narrow part. The screw anti-falling screw anti-falling equipment comprises a screwdriver, a four-foot gripper, a lifting handle anda telescopic sleeve, wherein the screwdriver comprises a knife handle, a knife rod and a cutter bar, the four-foot gripper is of a circular-tube-shaped structure, one end of the four-foot gripper penetrates through the telescopic sleeve and then is embedded into the lifting handle together with telescopic sleeve, four elastic pieces which are integrated with the four-foot gripper and are buckledin the end part are arranged at the other end of the four-foot gripper, the knife rod penetrates through the four-foot gripper, the lifting handle and the telescopic sleeve through a through hole formed in the lifting handle, and the knife rod, the four-foot gripper, the lifting handle and the telescopic sleeve are located on the same axis. According to the screw anti-falling screw anti-falling equipment, screws can be effectively and quickly disassembled through the cooperation of the screwdriver and the four-foot gripper and the auxiliary parts, so that the screws can be prevented from accidentally falling when screwed out or screwed in.

Description

[0001] Technical field: [0002] The invention relates to an aircraft maintenance support, in particular to a screw fall-off preventing device for narrow parts of an aircraft. [0003] Background technique: [0004] In the aircraft maintenance and support work, it is necessary to frequently disassemble the aircraft skin and the screws on various components. Some parts have narrow space and it is difficult to observe the operation situation; some difficult-to-remove parts (such as the engine compartment) are prone to screws falling into the aircraft This will lead to problems such as inconvenient operation, difficulty in finding fallen screws, and affecting work efficiency. [0005] Invention content: [0006] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a simple structure, through the cooperation of the screwdriver, the four-corner gripper and the auxiliary parts, to realize the effective and quick di...
