Description

Auxiliary handle for mowers {SUB HANDLE FOR A BRUSH CUTTER}

The present invention relates to a secondary handle for mowers, and more particularly, to a secondary handle for mowers, which solves the disadvantage of rotating the mower handle by the rotation and cutting pressure of the mower blade and is capable of mowing in an ergonomic and most comfortable posture. will be.

In general, a portable mower is a tool used to remove a weed or a lumber, and is usually carried on the shoulder of the operator and holding the handle with the two ends of the mowing blade to perform the work.

Conventional mowers rotate the engine 4, the support tubes 2 and 2 'connected to the engine, the slider tubes 3 and 3' slidably axially mounted on the support tubes, as shown in FIG. Cutter holders 15 and 15 'for rotatably supporting the cutter 13 and the cutter holder support the cutter holder such that the cutter holder can be pivoted about a pivot axis perpendicular to the longitudinal axis of the support tube and the rotating side of the cutter. And a connecting rod (14) (14 ') having one end connected to the slider tube and the other end pivotally connected to the cutter holder for converting the axial movement of the slider tube into the axis movement of the cutter holder. A drive transmission device 16 which extends through the holder support devices 14, 14 'and 34 and the support tubes and sliders to connect the cutter and the engine to allow the cutter to rotate and to allow the cutter holder to pivot; Portable which comprises 16a) (16b) 36 In the forceful mowing machine, the axis lever 21 is installed on either the support tube or the slider tube, and the wire W and the compression coil spring 26 move the lever's axis movement to the slider tube's axial movement. Portable power mowers, which are installed for converting and configured such that the levers can be held at a predetermined angle position to substantially secure the slider tube relative to the support tube, are disclosed in Korean Patent Publication No. 1987-000764. have.

By the way, the conventional mowing machine is a mowing blade is formed on the end of the handle is a force to rotate the handle in the counterclockwise direction by the reaction of the blade rotation and cutting pressure.

Therefore, the auxiliary handle for suppressing it is coupled to one end of the handle to hold it with the other hand to prevent the handle from rotating.

However, this is because the length and position of the auxiliary handle is completely fixed state can not be adjusted according to the physical condition of the worker, and also has the disadvantage that the operator can not work in a comfortable posture.

In addition, the vibration and pressure of the rotary blade with the handle rotating at high speed at the end is transmitted to the other arm through the auxiliary handle, which makes it very difficult to work for a long time, and makes it easy for the worker to feel tired and can lead to occupational diseases in severe cases.
