Hand-held tool

Abstract

The present invention relates to a hand-holding tool, which comprises a working part, a handle component supplied for the operator to operate and a link lever connecting the working part with the handle component; wherein, the handle component comprises a first handle and a second handle that is connected with the first handle; the handle component is movably connected with the link lever and is provided with a first position and a second position; moreover, the handle component can be fixedly connected with the link lever on the first position and on the second position; and the angle between the first handle and the link lever on the second position is different from the angle between the first handle and the link lever on the first position, and the angle between the second handle and the link lever on the second position is different from the angle between the second handle and the link lever on the first position. Through the adjustment way, the force applied on the handle component by the user is greatly reduced when operating with one hand; moreover, the handle component can provide a rather comfortable operation angle for the user.

Description

technical field [0001] The invention relates to an outdoor gardening cutting tool, in particular to a hand-held cutting tool. Background technique [0002] At present, hand-held tools such as mowers usually have a connecting rod extending longitudinally, one end of the connecting rod is provided with a work piece, and the other end of the connecting rod is provided with a shaped handle, which provides the user with a Hold the handle with your hand. Since the work piece is located at the end of the long connecting rod, in order to keep the work piece in contact with the ground, the user must use the strength of the arm muscles to hold the handle to maintain this operating state. After working for a period of time , the user will feel arm muscle soreness. In order to alleviate this situation, a second handle is provided on the handle bar of this type of tool in the known technology, which is used to provide the user with the other hand to hold it during operation. Two-handed ...

Problems solved by technology

However, when the second position is relative to the first position, the distance from the second handle to the vertical plane where the work piece is located increases, while the distance from the first handle to the vertical plane where the work piece is located does not change, and also That is to say, the moment arm of the torque exerted by the workpiece on the handle during work is lengthened, so the moment also becomes larger. In this way, although the user can achieve one-handed operation, it needs to provide a much larger force than that of two-handed operation. Obviously, this operation is also easy to cause fatigue and even muscle damage to the operator.

In addition, this one-handed implementation method also makes the second handle not too far away from the vertical plane where the work piece is located, making it difficult to adjust the second handle to a suitable position, thus affecting the user's one-handed operation comfort
