Abstract

The invention discloses a grass trimmer and a grass trimming head thereof. The grass trimmer comprises: a grass trimming head; a motor which drives the grass trimming head to rotate; in a cutting mode, the motor rotates forwardly to drive the grass trimming head to rotate in one direction; in an automatic winding mode, the motor reversely rotates to drive one of a spool or shell component to rotate in the opposite direction relative to the other; the grass trimming head comprises a shell component which is formed with an outer threading hole; the shell component comprises a shell and a threadoutlet buckle sleeve; the shell forms a shell cavity; the thread outlet buckle sleeve is fixed to the shell and forms the outer threading hole; the spool is provided with an inner threading hole through which a grass trimming rope penetrates; the inner threading hole is arranged in a flange part; and the distance from the thread outlet buckle to the flange part is smaller than the maximum outer diameter of the grass trimming rope. According to the invention, the grass trimming rope can be automatically wound to the spool under the action of the motor, the grass trimming rope can be directly inserted into the inner threading hole from the outer threading hole, deflection is not easy to occur, and the installation process of the grass trimming rope is convenient and fast.

Description

technical field [0001] The invention relates to a mowing machine and a mowing head thereof. Background technique [0002] A lawn mower is a garden tool used to trim lawns. The mower includes a mowing head. The high-speed rotation of the mowing head drives the mowing rope installed on it to rotate to realize the cutting function. [0003] The mowing head includes a spool for winding the mowing rope, and the mowing rope is gradually consumed due to wear and tear during the mowing operation. After working for a period of time, the user needs to replace the new grass rope and wind the grass rope on the spool. With the traditional trimming rope, the user needs to manually turn the spool so that the trimming rope can be wound onto the spool. The operation is cumbersome, the winding speed is slow, and it also brings certain risks because the human hand touches the trimming head during the winding process. [0004] The trimming head includes a housing assembly and a spool. The ...
