Embodiment Construction

[0011] As shown in Fig. 1 and Fig. 2, the embodiment of the present application adopts a set of reduction gears for transmission, and transmits the pulling force of the thin stay rope to the movable blade. The specific description is as follows:

[0012] It includes a machete-type fixed knife arm 1 and a movable blade 2, and the fixed knife arm 1 and the movable blade 2 are hinged to form the body of the high branch shears. Its features are: the knife back of the movable blade 2 is arc-shaped and processed with arc straight teeth 3, and the fixed knife arm 1 is equipped with a rope storage wheel 6 and a driving gear 7 coaxially rotating with the rope storage wheel, and the driving gear 7 Through deceleration intermediate gears 4 and 5 decelerate and mesh with the arc-shaped straight teeth on the back of movable blade 2 to realize the transmission. The above-mentioned intermediate gears 4 and 5 are integrated, the diameter of the intermediate gear 4 is small, the diameter of t...

Abstract

The present invention discloses a tree pruner for gardening which comprise machete type fixed cutter arm and movable cutter blade hinged with cutter arm. It is characterized in that the back of cutter blade of movable blade is arc-shaped and processed with straight tooth. The fixed cutter arm is installed with rope-storing wheel and driving gear coaxially rotating with rope-storing wheel. The driving gear is reduced in speed by medium gear and meshed with straight gear at back of movable blade for transmitting. Thin rope entwines the rope-storing wheel. Reset torsion spring is installed at rope-storing wheel axle and fixed cutter arm. Little pull force can cut the thick and hard branch due to the shift effect of gear transmission. The inventive pruner operate easily, save labor and will not pull top rod bent.

Description

technical field [0001] The application belongs to pruning shears for gardening. Background technique [0002] Branches need to be pruned in orchards, forestry, greening and other departments, and the commonly used tool is high-branch shears. For tall trees, the structure of the high-branch shears currently used is to hinge the scimitar-type fixed knife arm and the movable blade together, connect a horizontal lever to the movable blade, and have a socket at the end of the fixed knife arm. A push rod (generally a bamboo rod) is plugged into the fixed knife arm, and a pull rope is tied to the push rod. When pruning, lift the push rod with one hand to align the high branch shears with the branches, and pull the pull rope with the other hand to cut off the branches. The deficiency of this kind of high-branch shears is that it takes a lot of force to cut off the branches when pulling the stay rope, and the mandrel will be bent when the force is too great, which is very inconvenie...
