The utility model is composed of a cutting head box (9), a support rod (11), a support handle (12), a traction line (13), a traction guide tube (14), a tail end fixed seat (15), a traction handle (16), and a traction handle seat (17), wherein, a connecting position between the cutting head box (9) and the support rod (11) with adjustable length is adjustable so as to position fruit tree branches with different distances and directions at remote places. The support handle (12) and the traction handle (16) are held and pressed by force in opposite directions to shear fruit tree branches. The utility model has the advantages of convenient operation, and firm and durable structure.

Description

Length-adjustable extended type pruning fruit tree cutter

The utility model belongs to a kind of pruning fruit tree cutter.

At present, a kind of known pruning fruit tree cutter close with the utility model is made of the protruding cutter of disjunctor handle, the recessed cutter of disjunctor handle, spring, bolt; Bolt can the protruding cutter of fastening disjunctor handle, the recessed cutter of disjunctor handle; Spring is not subjected to external force to do the time spent at protruding cutter of disjunctor handle and the recessed cutter of disjunctor handle between two handles, to flick the edge of a knife that forms between protruding cutter and the recessed cutter; To the two disjunctor handles application of force in opposite directions, the edge of a knife can be contracted to and close up, to cut off the fruit tree branch that is sandwiched in the edge of a knife.Its shortcoming is: the pruning shear overall length is short and length is non-adjustable, when consequently pruning the fruit tree branch of distant place different distance, often need climb the tree or just can finish by supporters such as ladders.

The purpose of this utility model is to overcome the weak point of above-mentioned known pruning fruit tree cutter, and a kind of length-adjustable extended type pruning fruit tree cutter is provided.

The purpose of this utility model is achieved in that the protruding cutter of disjunctor handle that utilizes known pruning fruit tree cutter and the recessed cutter of disjunctor handle and does following improvement: remove the handle of the protruding cutter of disjunctor handle and make the protruding cutter of short handle (1) into, remove the handle of the recessed cutter of disjunctor handle and make the recessed cutter of short handle (2) into; Protruding cutter of short handle (1) except that protruding cutter and recessed cutter and the recessed cutter of short handle (2) and the connector (7) that screws axle (3), back-moving spring (4), directive wheel (5), head end holder (6), direction-adjustable that increases newly are loaded on upper and lower panel respectively and are had partly vertically between two plates (8) of the bit package (9) of the plate (8) of wide sealing arrow gauge formation by two profile unanimities and edge; Screw that axle (3) vertically passes plate (8) and outer common fastening protruding cutter of short handle (1) and the recessed cutter of short handle (2) that has back-moving spring (4) of nut (10) with being fixed on plate (8); Bit package (9) constitutes the utility model pruning fruit tree cutter jointly with the support bar (11) that increases newly, support handle (12), draught line (13), traction conduit (14), terminal holder (15), traction handle (16), traction handle seat (17); On terminate at the draught line (13) of the short handle end of the protruding cutter of short handle (1), directive wheel (5) is walked around in its lower end, pass that the upper end is fixed on that head end holder (6) is gone up and the lower end is fixed on flexible on the terminal holder (15) that the front portion with support bar (11) joins but traction conduit (14) that total length is constant, be connected and have on the traction handle (16) that rotary head (18) and the traction handle seat (17) that is contained in support bar (11) rear portion join; The support bar (11) that support handle (12) have been fixed in the lower end links to each other with bit package (9) by connector (7).

The support bar of above-mentioned utility model (11) by outer bar (19), can insert outer bar (19) and can be fastening with it with the location or get loose with the interior bar (20) that slides up and down, be contained in outer bar (19) the upper end with joint sleeve (21) formation of interior bar (20) that are locked.

The utility model has been compared following advantage and actual effect with known pruning fruit tree cutter:

1, the utility model has increased support bar and its overall length of telescopic adjustment by support bar, can conveniently touch nearby, the fruit tree branch of different distance at a distance; Increased connector can multi-faceted rotation with guarantee bit package at conveniently adjusted integral position on the support bar so that the edge of a knife is positioned on the different fruit tree branches, to cut off fruit tree branch.

2, traction handle of the present utility model can manufacture longer, laborsaving in use with the bigger thereby more known pruning fruit tree cutter that guarantees power arm and resistance arm.

3, easy to use, sturdy and durable.
