  • Patent number: 6675481
    Abstract: A gardening shears structure in which one handgrip has a circular recess sealed by a rotary plug. The rotary plug has a knob at the top that facilitates minimal force rotation during extrication, with a spring situated inside the circular recess enabling the smooth removal of the rotary plug, and a pliant body permeated with oil is inserted into a hollow sleeve at the bottom of the rotary plug such that it is partially exposed. After flower and branch cutting, a physically-worn or hand-carried cloth serves as a means of simple cleaning and following the wiping away of sap, leaf fragments, soil, and other grimy matter on the two blades of the truncating section, the oil permeating the pliant body is applied to shield them from air exposure to prevent corrosion and lubrication, thereby achieving the objective of maintenance.
