Problems solved by technology

[0004] Although the above-mentioned technical scheme realizes the hand-held operation by standing on the ground, the high branches can be trimmed, which is safe and convenient, but there are still many design defects; first, the device can only control a knife formed by the first blade and the second blade. group, it is impossible to realize the coexistence of multiple functional pruning knife groups in one device; secondly, the device relies on the handle at the bottom to manipulate the blade for cutting, which has the problem of supporting the device with one hand, and the handle is not easily manipulated due to the small force

Abstract

The invention aims at solving problems existing in the prior art, and provides a pruning device capable of switching knife sets. The pruning device comprises a knife head mechanism and an operating mechanism, wherein the knife head mechanism is arranged at the front end of a knife carrier; the operating mechanism is arranged at the back end of the knife carrier; the knife head mechanism is connected with the operating mechanism by a connecting mechanism. The operating mechanism is driven to act; while the knife head mechanism can be driven to integrally stretch or retract, a first knife set or a second knife set can also be controlled respectively to carry out cutting action; not only can a branch at a high position be clipped, but also the different knife sets can be selected according to different environmental conditions to work; the device is operated more conveniently and quickly.

Description

technical field [0001] The invention relates to a cutting device, in particular to a safe and convenient knife set switchable cutting device suitable for garden pruning and fruit picking. Background technique [0002] When garden operators prune and pick the branches, leaves, branches and fruits of trees growing at high places, the traditional method is that the operators climb to high places for pruning, which poses a great potential safety hazard, and there is nowhere to rely on for high-altitude operations. Work hard. [0003] Chinese invention patent 201420581638.4 discloses an improved pruning device, including a scissors part, a connecting device, a rod body and a transmission mechanism, wherein the scissors part includes blade one, blade two, a return spring and a chain, blade one is fixedly connected to the connecting device, and the blade Two are connected together with blade one by a hinge; the connection device is arranged between the scissors part and the rod bo...
