Grass trimmers

Abstract

The invention discloses a grass trimmer. The grass trimmer includes a grass cutting head and a motor; the motor is used for driving the grass cutting head to rotate with a rotation axis as a shaft; the grass cutting head comprises a spool and a head shell, the spool is used for winding a grass cutting rope, and the head shell is used for accommodating at least part of the spool; the grass cuttinghead is provided with an automatic winding mode; when the grass cutting head is in the automatic winding mode, the motor drives the spool or the head shell, so that with respect to the head shell, thespool generate relative rotation with the rotation axis as the shaft and rotating in a first rotation direction, thereby automatically winding the grass cutting rope onto the spool; the grass cuttinghead also includes an operation member for operation; the grass cutting head is also provided with a manual winding mode; and when the grass cutting head is in the manual winding mode, the operationmember is manually operated, so that with respect to the head shell, the spool is driven to generate relative rotation with the rotation axis as the shaft and rotating in the first rotation direction,thereby winding the grass cutting rope onto the spool. The grass trimmer combines manual winding and automatic winding into one body, and facilitates operation of users.

Description

technical field [0001] The invention relates to a garden tool, in particular to a lawn trimmer. Background technique [0002] As a kind of lawn trimming tool in a kind of garden class tool, mower has been widely paid attention to by people. Usually, the mowing machine includes a mowing head for mowing grass, and a spool for winding the mowing rope is arranged in the mowing head. At present, in order to wind the trimming rope to the spool, the user usually needs to remove the spool and manually wind the trimming rope. Obviously, such an operation is time-consuming and laborious, and reduces work efficiency. For this reason, there is also a mowing head on the market that can wind the mowing rope to the spool without disassembling the spool. However, the user still needs to manually turn a certain part on the mowing head to drive the spool to rotate so as to wind the mowing rope to the spool. The cord winds up to the spool, which can still be tiring for the user over time. ...

AI Technical Summary

Problems solved by technology

At present, in order to wind the trimming rope to the spool, the user usually needs to remove the spool and manually wind the trimming rope. Obviously, such an operation is time-consuming and laborious, and reduces work efficiency.

For this reason, there is also a mowing head on the market that can wind the mowing rope to the spool without disassembling the spool. However, the user still needs to manually turn a certain part on the mowing head to drive the spool to rotate so as to wind the mowing rope to the spool. The rope is wound to the spool, and the user will still feel tired in the long run

[0003] In the existing mowers, when manual winding is required, the user usually needs to hold the head shell with one hand and the operating part with the other hand. In this way, the user needs to operate with both hands at the same time, which will cause the mowing rope to be wound up to on the arm, causing interruption of the winding process

Moreover, when winding the wire, the bobbin will move up and down in the axial direction, which will easily cause the problem of one-sided winding

[0004] Furthermore, the size of the operating parts for the user to operate in the mowing head is usually relatively small, and serious wear and tear between the operating parts and the ground is likely to occur, thereby reducing the service life of the mowing machine

[0005] In addition, in order to align the outer hole and the inner hole of the mowing head, the user needs to adjust the alignment of the inner hole and the outer hole before threading, thereby reducing the work efficiency

[0006] Moreover, the weight of existing lawn trimmers is relatively heavy and the size is also relatively large
