Problems solved by technology
In the case of controlling the pay-off by pressing the switch, the user needs to interrupt the mowing process, and may need to change the holding state of the mower, and press the pay-off switch to control the pay-off, which is cumbersome and cumbersome for the user. It is easy to press the wrong switch to issue wrong operation instructions, and the mechanical or electronic switch is easily damaged, which reduces the service life of the mower
The way of tapping to control the mower's wire release requires tapping on the grass, which is easy to cause damage to the grass and is not conducive to the maintenance of the lawn

The invention discloses a grass trimmer, which comprises a grass trimming head including a head shell and a spool, wherein the spool is arranged in the head shell, and the spool is used for winding agrass trimming rope; a driving mechanism which is used for driving the grass trimming head to rotate around a first axis; a power supply which is electrically connected to the driving mechanism. The grass trimmer further comprises a connecting device which is connected with the grass trimming head and the power supply, wherein the connecting device extends along a second axis; a holding part whichis arranged on the connecting device and is held by a user; a control unit which is connected to the driving mechanism and controls the grass trimming head to operate; a detection device which is incommunication connection with the control unit, wherein the detection device is configured to sense displacement parameters of the grass trimming head, and when the displacement parameters of the grass trimming head are within a preset displacement parameter interval, the control unit controls the spool and the head shell to rotate relatively, so that a part of the grass trimming rope is separatedfrom the spool, and the grass trimmer conducts paying off. According to the grass trimmer, specific displacement control paying off can be conducted by controlling the grass trimmer, and operation iseasy and efficient.
Description
technical field [0001] The invention relates to a garden tool, in particular to a lawn trimmer. Background technique [0002] As a garden tool, the mower can be used to repair the lawn. Usually, the mower mows the grass through the mowing rope, which will cause loss during the mowing process of the mowing rope. It needs to be released by setting out the mowing rope. The existing The wire-feeding method of the current mower is usually by pressing the switch or tapping the grass head to let the wire out. In the case of controlling the pay-off by pressing the switch, the user needs to interrupt the mowing process, and may need to change the holding state of the mower, and press the pay-off switch to control the pay-off, which is cumbersome and cumbersome for the user. It is easy to press the wrong switch to issue wrong operation instructions, and the mechanical or electronic switch is easily damaged, which reduces the service life of the mower. The method of tapping to contro...
