AI Technical Summary
⚠Technical Problem
Existing pneumatic removal devices cannot provide a gripping effect during use, requiring a two-stage operation to remove the fuel injector, which is time-consuming and poses safety hazards.
⚗Method used
A pneumatic removal device was designed, comprising a grip assembly, an air intake assembly, and a vibration assembly. The grip is provided by the combined arm of the handle and the housing. Combined with the design of the vibration cylinder and the air exchange seat, the fuel injector can be directly removed, avoiding the phenomenon of spraying.
🎯Benefits of technology
It enables easy removal of the fuel injector, shortens operation time, improves safety, and prevents the fuel injector from flying out with the vibrator, making operation more convenient and safer.

Abstract
The invention is a pneumatic pulling device, which is provided with a holding group, an air inlet group and a vibration group. The holding group is provided with a handle and a shell. The handle is provided with at least one combination arm, which is transversely protruded on the outer surface of the handle. The shell is combined with the end of the at least one combination arm, which is away from the handle. The air inlet group is combined with the holding group and provided with a connecting sleeve. One end of the connecting sleeve is combined with the handle. The vibration group is combined with the holding group and the air inlet group and provided with a main shaft and a vibration cylinder. The main shaft is combined with the other end of the connecting sleeve and extends into the shell. The vibration cylinder is slidably sleeved on the main shaft and arranged in the shell. The main shaft is provided with a vibration force. The pneumatic pulling device is convenient to hold, shortens the operation time and improves the safety.
