Description

Novel take air compressor machine of scalable hand (hold) Technical Field The application relates to the field of air compressor devices, in particular to a novel air compressor with a telescopic handle. Background An air compressor is a device for compressing air, which is mainly used for providing compressed air as a power source so that a pneumatic tool (such as a nailing tool, a sanding tool, a paint spraying tool, etc.) can work normally. In use, the air compressor needs to be moved frequently, and is therefore usually equipped with casters and a handle by which the air compressor is pushed to move. However, the handles of the conventional air compressor are often integrated, and cannot meet the requirements of users with different heights, and the phenomenon that the handles are higher or lower is more or less caused. The fixed handle can not be suitable for all people, and the fatigue of arms is increased when the air compressor is used. Some existing telescopic handles can be locked at a limited number of fixed positions, and cannot realize continuous length adjustment, so that a user still cannot find an ideal handle length which completely accords with own operation habits. In view of this, there is a need in the market to provide a novel air compressor with a retractable handle to overcome the drawbacks of the prior art.
