Grass trimmer and grass trimming head thereof

Abstract

The invention provides a grass trimming head connected with a motor output shaft of a grass trimmer. The grass trimming head comprises a shell, a winding shaft and a support cap. One end of the shell is connected with the end of the motor output shaft, and the other end of the shell is provided with an opening. The winding shaft is arranged in the shell and rotates along with rotation of the shell. At least one end of a grass trimming rope wound on the winding shaft extends out of the shell. The support cap is rotationally arranged at the end, close to the opening, of the winding shaft and is exposed out of the shell through the opening. The service life of the grass trimming head is prolonged, output power consumption of a motor is reduced, and comfort level of users can be improved to some extent.

Description

technical field [0001] The invention belongs to the field of garden electric tools, and in particular relates to a grass mowing machine and a grass mowing head thereof. Background technique [0002] The lawn trimmer is a universal and practical garden tool, especially suitable for trimming grasses such as villa lawns and garden lawns. At present, the mowers on the market are roughly divided into percussion pay-off, automatic pay-off and manual pay-off. When setting off the wire by tapping the lawn trimmer, the user needs to touch the tapping head to the ground first, and then loosen the cooperation between the winding shaft and the shell before the wire can be released. During the winding process, the tapping head and the The winding shaft rotates together, because the striking head is in contact with the ground, so the striking head will be worn by the ground during the rotation, and the output power consumption of the motor will be increased, which will affect the life o...

AI Technical Summary

Problems solved by technology

When setting off the wire by tapping the lawn trimmer, the user needs to touch the tapping head to the ground first, and then loosen the cooperation between the winding shaft and the shell before the wire can be released. During the winding process, the tapping head and the The winding shaft rotates together. Since the striking head is in contact with the ground, the striking head will be worn by the ground during the rotation process, and the output power consumption of the motor will be increased, which will affect the battery life.

[0003] As for the trimmers with automatic and manual pay-offs, during actual use, the operator will unconsciously touch the trimmers to the ground frequently, which will inevitably lead to increased wear of the trimmers rotating at high speed, and the trimmers will The power consumption of the grass machine will also increase, which will also affect the performance of the motor

Even though many lawn trimmers indicate in the instruction manual to avoid touching the percussion cap to the ground during use, this still cannot fundamentally solve the above problems
