Abstract:
A lever-type grease gun includes: a hollow cylinder having a first end and a second end opposite to the former; a front-end cover located at the first end and provided with a nozzle part and a mounting portion; a back-end cover located at its second end; an oil pushing rod located at the front-end cover, capable of moving in the front-end cover under push forces and closer to the back-end cover than the mounting portion, and having an oil pushing rod part; and a handle unit comprising a lever having a pivoting part to match the mounting portion, a pressing part and a plurality of straight slots between the two and a connecting set inserted in the oil pushing rod part and the straight slots and moving in the straight slots, thus reducing the force required to fill grease.

Claim (Index 1):
A lever type grease gun comprising:\n a hollow cylinder, having a first end and a second end opposite to the first end; a front-end cover, located at the first end of the hollow cylinder and provided with a nozzle part and a mounting portion; a back-end cover located at the second end of the hollow cylinder; an oil pushing rod disposed at the front-end cover, located closer to the back-end cover than the mounting portion, capable of moving in the front-end cover under push forces, and having an oil pushing rod part located outside the front-end cover; and a handle unit comprising a lever and a connecting set, wherein the lever is mounted on the front end cover in a pressable manner, and capable of being pressed from a first position toward a second position, the lever includes: a pivoting part pivotally connected to the mounting portion, a pressing part, and a rod portion between the pivoting part and the pressing part, the rod portion has a bottom surface and a straight slot extending along a length of the lever and having a first slot end and a second slot end which is closer to the pivoting part than the first slot end, the straight slot has an extension line passing through the first and second slot ends, the extension line is parallel to the bottom surface; the connecting set is inserted through the oil pushing rod part, disposed in the straight slot and movable between the first slot end and the second slot end; when the lever is in the first position, the connecting set is located at the first slot end, when the lever is pushed to the second position, the connecting set is moved to the second slot end, while the lever is being pushed to move from the first position to the second position, the connecting set is moved from the first slot end to the second slot end, and a linear distance between the connecting set and the pivoting part gradually decreases.
