Description

High branch shears without segmentation

The present invention relates to a gardening appliance; in particular, to a tall branch cutter for allowing the user to easily trim or harvest the foliage or fruit of the plant.

The common high-branched cutting system is used to trim or harvest the branches or fruits of the plants at high altitudes, so that the user can work without having to climb up to the heights, and improve the safety during operation; Most of the high-cut scissors used in the conventional function have the function of adjustable length.

The conventional high-branch cutting is as disclosed in Chinese Patent Publication No. 429739 "High Branch Shear Telescopic Positioning Improvement", China Patent Publication No. 501397 "High Branch Shear Improvement Structure", or as shown in Figures 1 to 3, including A telescopic positioning device is disposed in one of the telescopic tubes 10 of the high-pruning shears, and includes a base 11, a moving rod 12 and a positioning member 13 which is hollow and upwardly permeable. The front and rear side walls 111 and 112 are axially opposed to each other, and the front and rear side walls 111 and 112 respectively define a slot 113. The two slots 113 are oppositely and respectively penetrate the front and rear side walls 111 and 112, and the bottom surface of the groove 113 respectively forms a supporting surface 114; the positioning member 13 is attached to the base 11 and has a plurality of buckles laterally A plurality of elastic members 14 are disposed between the base 11 and the positioning member 13; the moving rod 12 passes through the two slots 113 and spans the support surface 114, and the moving rod 12 is disposed corresponding to the plurality of buckles 131. a plurality of sets of upwardly facing notches 121 for engaging the buckle 131; when the positioning member 13 is depressed, the buckle 131 will be embedded in the notch 121 to fix the moving rod 12; and when the positioning member 13 is not pressed, the elastic member 14 is pushed up, so that the buckle 131 leaves the notch 121 to allow the moving rod 12 to move; Moving the plurality of notches 121 on the rod 12, so that the conventional high branch is cut into a phase-adjustable and telescopic length knot. Structure.

However, the conventional high branch is positioned by the notch 121 provided on the moving rod 12 when the length is adjusted, but considering the structural strength, the number of the notches 121 that can be disposed on the moving rod 121 is limited, resulting in the user. Often, it is impossible to adjust to an appropriate length, or it is impossible to surely position the buckle 131 in the notch 121.

In view of this, the inventors have conceived and further studied, and finally invented a high-branch shear that can be stretched without segments.
