Problems solved by technology

[0002] When a certain type of UAV wheel is used for tire replacement and maintenance, the cotter pin of the wheel is easily deformed due to long-term use or improper disassembly, which makes it difficult to remove. If necessary, it is necessary to use a cutting tool to assist in the removal, which greatly reduces work efficiency and cause unnecessary damage to the wheels

Abstract

The invention discloses an extractor of a cotter pin of an airplane wheel of an unmanned aerial vehicle. The extractor is a device specially used for taking out the cotter pin of the airplane wheel ofa certain type of unmanned aerial vehicle. The extractor includes a cotter pin extractor body, a connecting screw, an upper plate, an upper ball head, a lower ball head, a screw nut and a plug pin. The extractor of the cotter pin of the airplane wheel of the unmanned aerial vehicle has a simple structure and a small number of parts, profiles can be used for simple processing, and the cost is low;and meanwhile, using is easy and convenient, and damage to the airplane wheel when the cotter pin is taken out can be avoided.

Description

technical field [0001] The invention relates to a cotter pin extractor for a wheel of an unmanned aerial vehicle, in particular to a cotter pin extractor for a certain type of unmanned aerial vehicle, belonging to the field of aviation machinery. Background technique [0002] When a certain type of UAV wheel is used for tire replacement and maintenance, the cotter pin of the wheel is easily deformed due to long-term use or improper disassembly, which makes it difficult to remove. If necessary, it is necessary to use a cutting tool to assist in the removal, which greatly reduces work efficiency and cause unnecessary damage to the wheels. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies in the prior art, a kind of unmanned aerial vehicle wheel split pin extractor is proposed. This device can be used to quickly and reliably remove the cotter pin of the wheel, avoiding damage to the wheel when using traditional...
