Description

  The present invention relates to a horticultural pruning tool, and more particularly to a high pruning shears structure used for pruning work in a high place.

  Generally, when pruning a branch, a tall plant or a fruit tree, it is carried out using a high branch cutting shear. Furthermore, most of the high branch cutting ridges have a length adjusting function in order to apply to each height.

  1 to 3, reference is made to a high-branch cutter having a known length adjusting function. The adjustment interlocking mechanism provided on the telescopic tube 90 of the high branch cutting rod includes a pedestal 91, a moving shaft 92, and a fixture 93. The pedestal 91 forms an upwardly cut-out shape, and the pedestal 91 has a front side wall 911 and a rear side wall 912. The front and rear side walls 911 and 912 are respectively formed with grooves 913, and two grooves 913 are formed. The support surfaces 914 are respectively formed on the bottom surfaces of the grooves 913. The fixing tool 93 is closed on the pedestal 91, and a plurality of hanging bars 931 are provided in the lateral direction, and a plurality of elastic elements 94 are provided between the pedestal 91 and the fixing tool 93. The moving shaft 92 is provided so as to pass through the two grooves 913 and straddle the support surface 914. The moving shaft 92 is provided with a plurality of upward notches 921 corresponding to the plurality of hanging rods 931, and the hanging rod 931. Provide for the mooring of. When the fixing tool 93 is pressed downward, the hanging rod 931 is fitted into the notch 921, and the moving shaft 92 is fixed. When the fixture 93 is not pressed, it is pushed upward by the elastic element 94, the hanging bar 931 leaves the notch 921, and the moving shaft 92 can move freely. A plurality of cutouts 921 provided on the moving shaft 92 adjusts the high branch cutting bar in a stepwise manner to form a mechanism capable of extending and contracting its length.

  However, when adjusting the length of a known high-branch cutter, it is fixed by a notch 921 provided on the moving shaft 92. Since the structural strength must be maintained, the number of notches 921 that can be installed on the moving shaft 921 is limited. Thus, it often happens that the user cannot adjust to the proper length or cannot reliably secure the hanging bar 931 to the notch 921.
