[0077] Specifically, when the user needs to adjust the direction of the rotating grass-beating head 700, the user presses the locking button 112. The locking button 112 causes the locking ring 111 to move down, and the locking ring 111 compresses the locking spring 113. At this time, the anti-rotation block 116 on the locking ring 111 can disengage from the anti-rotation hole 115 on the locking sleeve 114. At this time, the user can rotate the first rod 200 so that the first rod 200 rotates relative to the control handle 100. Then, the user releases the locking button 112, and the locking ring 111 resets under the action of the locking spring 113, so that the anti-rotation block 116 on the locking ring 111 can engage with the anti-rotation hole 115 on the locking sleeve 114, thereby fixing the locking sleeve 114 and preventing the first rod 200 from rotating.

[0078] The locking sleeve 114 has multiple anti-rotation holes 115, which allow the user to rotate the first rod 200 by 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc., as needed, so that the user can carry out different vegetation treatment work.

[0079] This embodiment provides a lawn mower, including a lawn mower body structure.
