Abstract

The utility model relates to a telescopic long-handle pruning shears, which comprises a hinged first scissor arm (1) and a second scissor arm (2), the first scissor arm (1) and the second scissor arm (2) The rear part is respectively connected with a telescopic extension rod 1 (3) and an extension rod 2 (4). (31, 41), the front ends of the innermost telescopic joints (31, 41) are respectively set on the rear ends of the first scissor arm (1) and the second scissor arm (2), and the outermost telescopic joints (31, 41) The back end of the back end is respectively suitably equipped with anti-slip rubber sleeve (32,42). It has the characteristics of convenient carrying, good labor-saving effect, simple structure, low cost, easy operation and fast pruning speed. It is easier to use it to pruning, the hands are stronger, the pruning force is greater, the cut is more neat, and it is more beneficial to the growth of trees.

Description

Telescopic long is pruner

Technical field

The utility model relates to garden tool set, is specifically related to a kind of pruner.

Background technology

Existing length is carried inconvenience to the long of pruner being the integral type structure, generally adopts the dragline type mode of operation, and the use labor-saving effect that has is good, but the complex structure cost is high; Have then be not easy to the operation, use the power of not using, beta pruning speed is fast not.

Summary of the invention

The purpose of this utility model provide a kind of easy to carry, use that good, the simple in structure cost in labor-saving effect is low, convenient operation, the fireballing telescopic long of beta pruning be pruner.

Technical solution of the present utility model is: it comprises first cutting arm and second and cut arm of being hinged, first cuts arm and second cuts the rearward end of arm and is connected with respectively telescopic extension bar one and extension bar two, extension bar one and extension bar two are made of the multi-joint telescoping joint together of mutual sheathing from inside to outside respectively, the front end of penetralia telescopic joint is set with and is connected to first and cuts arm and second and cut on the rear end of arm, and the rear end of most external telescopic joint is respectively installed with antiskid glue sleeve.

Technique effect of the present utility model is: it has easy to carry, uses the labor-saving effect good, and cost simple in structure is low, convenient operation, the fireballing characteristics of beta pruning.Use its beta pruning to be more prone to, both hands are exerted oneself, and beta pruning strength is larger, and clip is more neat, and is also more favourable to arboreal growth.
