WIPO Patent Application WO/2022/241810
Kind Code:
A1
Abstract:
Disclosed in the present invention is a tree saw, comprising: a machine body provided with a saw chain mechanism and a driving mechanism, the driving mechanism being connected to the saw chain mechanism and used for driving the saw chain mechanism when a circuit of the tree saw is in a connected state, and the machine body being connected to a rotary button; and a handle connected to the machine body and provided with a trigger and a reverse self-locking button, wherein the machine body and at least one of the trigger and the reverse self-locking button form an interlock or cooperatively control the circuit of the tree saw to be in the connected state, so as to ensure that the saw chain mechanism cannot be activated when the machine body and/or the handle is/are in a rotary adjustment state. By means of the tree saw provided in the present invention, cutting is performed with a cutting surface of the saw chain mechanism forming a certain angle with the handle, which can completely avoid the region where the cut branches fall off after cutting, and also safely and conveniently cut the branches on the back side of a trunk so as to solve the problem of inconvenience for a conventional chainsaw operator due to it not being easy to approach an object to be cut to operate on the back side. In addition, when cutting roots of shrubs, the hands can be kept away from the ground to prevent scratches, the cutting surface is closer to the ground, the cut stump can be flush, and the operation is more flexible and safe.
