Abstract

The invention provides an orchard shears safety device, wherein a first stopping part and a second stopping part which corresponds with first stopping part, are set at the preset site inside the handle and a circular groove is set in the middle of the first stopping part; a connection part has one inner hole in hollow shape and one end of the inner hole is equipped with a flange to fasten the circular groove, being able to rotate and another end of the inner hole is equipped with a female thread; the second stopping part is equipped with a male tread at the end opposite to the female thread. The connection part is screwed on the second stopping part when the orchard shears are not used , so that the handle is braked, therefore the human is prevented from accidentally injured due to the sudden open of the orchard shears when the orchard shears are not used.

Description

technical field [0001] The invention relates to a safety device for gardening shears, in particular to a locking safety structure when the gardening shears are not in use, which is arranged at a predetermined position inside the handle and prevents the handle from opening and closing through the action of a connecting piece. Background technique [0002] see Figures 5A-5C As shown, it is the "knife-scissors fastening structure improvement" of Taiwan's new certificate No. M216450, which mainly includes: a screw fitting 61 forms a bump 611 on the peripheral surface of the head end, and the bump 611 has a concave Groove 612, an opening 613 is formed on the other side to resist the protruding end 621 of the buckle 62, and the threaded part 61 passes through the hollow groove 622 of the buckle 62; a buckle 62 has a hollow groove 622 at one end, and the hollow The height of the groove 622 is slightly smaller than the depth of the lug 611 on the screw fitting 61. A buckle groove 6...
