Description

Gardening shears structure

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

According to the gardening work, gardening shears are often used to trim the branches and leaves of plants to maintain the neatness of plant landscaping. The gardening process is very beneficial to cultivating aesthetics and self-cultivation. Proper pruning of branches and leaves can prevent the growth direction of trees from obstructing vision and roads, and can greatly reduce the loss of life and property caused by branches falling due to strong winds during typhoons and heavy rains.

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 prune 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.
