Plant trimmer

Abstract

The invention provides a plant trimmer, which comprises a cutting element, a supporting plate for supporting the cutting element, a motor for driving the cutting element, a first handle component, a second handle component, a locking mechanism for fixing and connecting the second handle component with the first handle component in a detachable manner, and a connecting mechanism between the first handle component and the supporting plate, wherein the first handle component or the second handle component performs an linear motion toward or away from the supporting plate in an operable manner; and the connecting mechanism converts the linear motion of the first handle component or second handle component into the swinging of the supporting plate.

Description

technical field [0001] The present invention relates to a plant trimmer, in particular to a plant trimmer with an extension bar, such as a chain saw with an extension bar. Background technique [0002] At present, there are many tools for pruning plants on the market, such as scissors for pruning some relatively small branches and leaves. There are also pruners and chain saws that are usually used to trim relatively thick trees and so on. [0003] A traditional chainsaw includes a working head consisting of a chain and a support plate used to support the chain. The chain is driven by a motor and rotates around the support plate. The traditional chainsaw also includes a main handle located at the rear of the work head. Auxiliary handle between head and main handle. When cutting, the working head of this traditional chain saw is usually only driven by the motor so that the chain rotates around the support plate, and the support plate is generally stationary. During the cutti...

However, this structure makes the operation not very comfortable in some cases. For example, when it is necessary to cut high branches, it is more difficult for the operator to apply force; in addition, when it is necessary to cut wood placed on the ground, the operator needs to bend Work with your lower back, which can easily tire you if you work for a long time

[0005] In addition, if the branches on the taller trees are to be cut, this traditional chain saw usually includes an extension rod, which is usually detachably fixedly connected to the main handle of the chain saw. During operation, the operator holds the extension rod , applying force in the cutting direction, this operation is often laborious

[0006] U.S. Patent No. US7152328B2 discloses a chain saw including a working head, a main handle and an extension rod. When cutting higher branches, the user fixes the extension rod to the main handle, and the extension rod is electrically connected to the main handle. The user can operate as long as he holds the extension rod, but when operating this kind of chain saw, the operator needs to apply a large force in the cutting direction, which will make the operation process more laborious
