[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structures. The working principle of a vacuum cleaner is that an electric motor drives the blades to rotate at a high speed, generating a negative air pressure inside a sealed housing to suck dust debris. After the vacuum cleaner adsorbs dust, in order to supply it to the inside of the dust box, a corresponding hose is needed to realize the guiding and conveying of the dust. For the hose used in the vacuum cleaner, in order to avoid damage to the elbow caused by excessive bending, it is necessary to pre-sample and conduct corresponding testing operations during the production process of the elbow. When the existing testing device conducts testing operations on the hose, since it mostly adopts a reciprocating left-right swing structure to realize the swing and bending performance testing of the elbow, when it conducts a simple left-right swing, because it cannot simulate the stretching and shrinking operations during the use of the vacuum cleaner, the simple swing testing is unreliable and the testing effect is poor.
