The specific contents are as follows:

[0014] 1. By storing some spare ropes, when the mowing rope is worn or broken, the spare rope can be directly pulled out for replacement. When the mowing rope rotates at high speed, it can contact the protective plate and push the protective plate to rotate. The spring resilience can not only protect the mowing rope, but also play a shock-absorbing role in its high-speed rotation;

[0015] 2. Rotate the adjusting rod to drive the disc down through the threaded transmission with the disc body, and pull the movable plate down synchronously to slide in the fixed groove, drive the movable plate away from the fixed plate, release the lock on the mowing rope, so as to pull the spare rope to extend. After the adjustment is completed, rotate the adjusting rod in the opposite direction to drive the movable plate to rise and merge with the fixed plate to achieve the clamping of the mowing rope. After clamping, the firmness can be further improved by setting the limit block to prevent the mowing rope from loosening or detaching during rotation. BRIEF DESCRIPTION OF THE DRAWINGS
