Fixing device

Abstract

The invention relates to a fixing device which comprises a fixing base and at least two rope clamping units used for fixing a grass mowing rope, each rope clamping unit comprises at least two locking pieces rotationally connected with the fixing base, and the fixing base is provided with an inserting and pulling hole used for the grass mowing rope to enter and exit; a channel for one end of the grass mowing rope to pass through is formed between the at least two locking pieces, the channel is located in the insertion and extraction hole, and after the at least two locking pieces are away from each other, the width of the channel is increased to be larger than the rope diameter of the grass mowing rope so that one end of the grass mowing rope can enter and exit the fixing base through the channel; after the at least two locking pieces get close to each other, the width of the channel is reduced to be equal to the rope diameter of the grass mowing rope, so that one part of the grass mowing rope is fixed in the channel, the at least two locking pieces get close to each other under the force deviating from the center of the fixing base, and the width of the channel is reduced to be smaller than the rope diameter of the grass mowing rope so that one part of the grass mowing rope can be locked in the channel; the grass trimming rope is very convenient to install, the probability that the grass trimming rope is thrown out of the grass trimming head is small, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of garden tools, in particular to a fixing device. Background technique [0002] The living environment is a problem that people are more and more concerned about. Lawns are arranged in parks, communities, golf courses and other venues to beautify the environment. However, in order to maintain the above environment regularly, to avoid the free growth of grass and cause the lawn to be messy. As a common garden tool, lawn trimmers are more and more widely used. The lawn trimmer uses a motor to drive the grass trimming head to rotate at high speed, and the grass trimming head drives the grass trimming rope on it to rotate at high speed to cut the turf and trim the shape of the lawn. [0003] The grass cutting rope is bent and embedded in the grass cutting head, and rotates at high speed with the grass cutting head, but the grass cutting rope will be worn after long-term use, the cutting effect will be reduced, ...

AI Technical Summary

Problems solved by technology

[0003] The mowing rope is bent and embedded in the mowing head, and rotates with the mowing head at high speed, but the mowing rope will wear out after a long time of use, and the cutting effect will be reduced, so it needs to be replaced in time

At present, when the user replaces the mowing rope, he needs to disassemble the mowing head as a whole, remove the old mowing rope inside, reinstall the new mowing rope, and then fasten the mowing head to install. The whole process is very cumbersome , inconvenient to install

And after the user installs by himself, the reliability of the mowing rope after the fixed installation is more difficult to guarantee, which will easily cause the situation that the mowing rope is thrown out of the mowing head, which will affect the safety of life and property when serious. Although the prior art has a one-way lock The mowing head is only equipped with a locking piece on one side of the passage where the rope passes, and the other side uses a fixed structure to assist in clamping the mowing rope. When the mowing head rotates, the centrifugal force generated will throw out the mowing rope. If the centrifugal force is too large, the mowing rope can easily overcome the clamping of a single locking piece and be thrown out of the mowing head, making the mowing head far from being reliable enough to meet the use requirements
