Abstract
A pneumatic grease gun includes a handle, a storage container, a coupling tube and a cylinder assembly. The handle has a grip and a bushing. The grip is located at one side of the bushing. The cylinder assembly has two ends connected respectively to the bushing and coupling tube. The coupling tube holds a feeding tube which has one side communicating with the storage container. The feeding tube has a tubular wall coupled with a protrusive O-ring close to the cylinder assembly. The cylinder assembly includes a feeding rod running through the feeding tube and surrounded by the O-ring to prevent grease held in the storage container from flowing back to the cylinder assembly, thus increases the lifespan thereof. The grip is positioned at an adequate location to save user's effort in holding, hence can better meet use requirements.
