Description

Gardening shears structure

The present invention relates to a gardening shears structure, in particular to a labor-saving and smooth gardening shears structure.

Many places plant trees for landscape design and to provide shade. The direction of tree growth is sometimes difficult to control. In addition, Taiwan is located in the tropics, and common tree species are evergreen broad-leaved species, not coniferous trees. Broad-leaved trees are not very tall and have lush branches and leaves. They grow faster and need to be pruned frequently to prevent heavy branches and leaves from falling and injuring people, or blocking vision and movement. Fruit trees also need to prune excess branches to ensure that the number of fruits does not disperse too many nutrients, resulting in poor fruit quality.

However, the common garden shears are often a variation of the common scissors. The blade length and handle length of the scissors are changed to suit gardening work. However, in order to save effort, the traditional garden shears only increase the length of the handle to achieve the effect of saving effort by using the lever principle, and the pivoting of the shear blade is still achieved by a pivot. This method is sufficient for mowing large areas of lawn, but if it is used to mow hard branches, it will cause the user to get half the result with twice the effort and extra effort.

Therefore, the inventor of this invention took this into consideration and came up with the idea of invention. He then designed it based on his years of experience, conducted many discussions and conducted sample tests, and made many revisions and improvements before launching this invention.

The technical problem that the present invention aims to solve is to provide a labor-saving and smooth garden shear structure in response to the above-mentioned deficiencies of the existing technology.

The cutting blades are stacked from bottom to top in the order of the slide member, the first cutting blade, and the second cutting blade. When the user holds the handle, the slide member and the second cutting blade are located on the right side. By means of the above structure, the handle is opened outward during use, and the first cutting blade and the second cutting blade are pivoted to separate. The first cutting blade is pressed against a branch and the first cutting blade and the second cutting blade clamp the branch. Then the handle is held inward to move the second cutting blade toward the first cutting blade to complete the cutting action.

Preferably, each of the two handles is provided with a buffer rod. When the handles move inward to the limit, the two buffer rods will push each other to maintain the distance between the two handles. The top of the buffer rod is elastic and has a buffering effect.

Preferably, a reinforcement hole is recessed inside the handle, and a reinforcement piece is screwed into the reinforcement hole for the handle to abut against, so as to prevent the handle from sliding toward the inside of the handle.

Through this invention, the slide ring and the slide groove are matched to allow the slide groove member, the first shear blade and the second shear blade to perform constrained movement. Since the slide groove restricts movement only in a straight line, the relative movement is more stable, saving time and effort, and is smoother.
