Claim 3:
4. A high pressure-generating multi-point lubricant injector comprising:
an upper body in which a motor and a battery for driving the motor are mounted; and
a lower body coupled to the upper body, the lower body comprising
a space of a predetermined size,
a cartridge detachably mounted in the space and filled with a lubricant therein,
a piston provided inside the cartridge and comprising a nut,
a screw shaft coupled to the nut, configured to lift and lower the piston while being rotated, and formed through an upper portion of the cartridge,
a driven gear coupled to the screw shaft, and
a driving gear configured to drive the driven gear by receiving rotational force of the motor,
wherein the driven gear comprises multiple driven gears arranged symmetrically around the driving gear located at an upper center of the lower body, the screw shaft comprises multiple screw shafts arranged at positions corresponding to the driven gears, and the cartridge comprises multiple cartridges each including the piston coupled to each of the screw shafts and arranged at positions corresponding to the driven gears so that the lubricant is extruded to the outside from each of the multiple cartridges.
