Grass trimming head which is simple to operate and reliable to use and grass trimmer

Abstract

The invention provides a grass trimming head which is simple to operate and reliable to use and a grass trimmer. The grass trimming head comprises a shell body, a grass trimming rope, a wire ring which is arranged in the shell body and a locking device, wherein two wire outlet hole are formed in the shell body, and the grass trimming rope runs through the wire outlet holes; the wire outlet holes are evenly distributed along the circumference of the shell body, and the two outlet holes are a first wire outlet hole and a second wire outlet hole respectively; a central hole is formed in the wirering, the locking device is arranged at the central hole, and threading channels which transversely penetrate the wire ring and are communicated with the central hole are arranged on the side of the circumference of the wire ring; the threading channels are communicated with the first wire outlet hole and the second wire outlet hole, and the grass trimming rope sequentially runs through the firstwire outlet hole, the threading channels and the second wire outlet hole so as to penetrate the grass trimming head so that a user can conveniently load the grass trimming rope on the wire ring of thegrass trimming head without the need of disassembling the shell body; therefore, the operation of replacing the grass trimming rope can be simple and convenient, the position of the grass trimming rope can be locked through the locking device, and therefore it is ensured that the grass trimming rope can not be thrown out when in use, so that the grass trimming head can be used reliably.

Description

technical field [0001] The invention relates to the technical field of mowing heads, in particular to a mowing head which is easy to operate and reliable in use. Background technique [0002] The mowing machine is a common garden tool, and its main principle is to use a motor or an engine to drive its mowing head to rotate at a high speed. The end of the mowing line stretches out through the outlet hole on the mowing head housing, and when the mowing head rotates at a high speed, the mowing rope also rotates at a high speed thereupon, thereby realizing the effect of cutting. [0003] When the mowing rope protruding out of the mowing head housing breaks or is worn out, how to replenish the mowing rope becomes an urgent problem to be solved. The prior art is to replace the assembly structure in the mowing head housing Disassemble, then take out the winding reel, and carry out manual winding. For the user, it is not easy to wind the wire on the reel and assemble the grass cutt...

Problems solved by technology

[0003] When the mowing rope protruding out of the mowing head housing breaks or is worn out, how to replenish the mowing rope becomes an urgent problem to be solved. The prior art is to replace the assembly structure in the mowing head housing Disassemble, then take out the winding reel, and carry out manual winding. For the user, it is not easy to wind the wire on the reel and assemble the grass cutting head. Secondly, manual winding takes a lot of time. , if the winding direction is wrong, the normal pay-off cannot be realized, which makes the use of the mowing head extremely inconvenient
