Embodiment Construction

[0029] Please refer to Figure 1 to Figure 3 , this embodiment provides a grass cutting head 100, which can be driven by a driving motor (not shown in the figure) and trims weeds, vegetation, etc., which includes a rotating head 110 and a Hay rope holder 120. The rotating head 110 is provided with a main shaft rotating part 111 and a fixing part 112 connected with the main shaft rotating part 111, and a limiting part 113 is also arranged on the fixing part 112, and the mowing rope holder 120 is rotatably arranged in the limiting part 113 . The limiter 113 can limit the axial movement of the mowing rope holder 120, the limiter 113 can be one or more, and its number can be determined according to the specific working conditions. In a preferred embodiment, the limiter 113 is four and each limiting member 113 is evenly distributed on the fixing member 112, so that it can ensure that the mowing head 100 can fully improve the mowing efficiency when it is working.

Abstract

The invention discloses a mowing head, which comprises a rotating head and a mowing rope holder connected with the rotating head. The grass rope holder can be rotatably arranged in the limiter. When the mowing head is in use, the mowing rope is installed on the mowing rope holder. When the mowing rope on the mowing head touches hard objects such as stones, thick branches or steps, the mowing rope holder can The internal rotation of the limiter effectively reduces the contact force of hard objects on the mowing rope, so as to prevent the problem of wire breakage caused by mowing. In addition, the present invention also discloses a grass trimmer with the above grass trimming head.

Description

technical field [0001] The invention relates to the field of garden power tools, in particular to a mower head and a mower equipped with the mower head. Background technique [0002] As a portable garden power tool, the lawn mower is widely used in trimming weeds and vegetation in villa lawns and garden lawns. At present, the mowing head of the mowing machine can generally be divided into a mowing rope type and a blade type. Among them, the mowing rope type mowing head is to install the mowing rope on the mowing head, and drive the mowing head to rotate at a high speed through the driving motor arranged on the mowing head, so that the mowing rope will generate rotational inertia and pull the weeds away. , Vegetation cutting. During the use of the mowing machine, the mowing rope often breaks after touching hard objects such as stones, thick branches or steps, which will cause trouble for the mowing machine. Contents of the invention [0003] Based on this, it is necessar...
