When mowing the lawn, the staff can adjust the clutch 121 according to the needs of use to achieve gear shifting operation, and then adjust the speed of the cutter 118. In case of an unexpected situation, the staff can operate the clutch 121 to switch to a low speed gear. At this time, the speed of the output end of the motor 115 is reduced, and when the connecting shaft 116 is combined with the speed of the output end of the motor 115, the clutch 121 can achieve auxiliary braking through the speed difference between the output end of the motor 115 and the connecting shaft 116, so that the cutter 118 stops rotating, thereby improving the safety of the staff when mowing the lawn.

[0023] Secondly, the protective shell 122 is fixedly connected to the clutch 121 and is located at the bottom of the clutch 121. The fixed shaft 123 is fixedly connected to the secondary pulley 120 and is located at the bottom of the secondary pulley 120. The upper bevel gear 124 is fixedly connected to the fixed shaft 123 and is located at the bottom of the fixed shaft 123. The mounting shaft 125 is rotatably connected to the protective shell 122 and is located on one side of the protective shell 122. The lower bevel gear 126 is fixedly connected to the mounting shaft 125 and meshes with the upper bevel gear 124. The transmission sub-gear 127 is fixedly connected to the mounting shaft 125 and is located on the mounting shaft 125 near the lower bevel gear 12 6, the transmission main gear 128 is fixedly connected to the transmission shaft 106 and meshes with the transmission sub-gear 127. When the sub-pulley 120 starts to rotate following the main pulley 117 on the belt 119, the fixed shaft 123 can follow the sub-pulley 120 to rotate and drive the upper bevel gear 124 to rotate, so that the lower bevel gear 126 meshed with it follows and rotates on the mounting shaft 125, driving the transmission sub-gear 127 to rotate, so that the transmission main gear 128 meshed with the transmission sub-gear 127 starts to rotate, driving the transmission shaft 106 to rotate, and can drive the tire 105 to rotate, so that the lawn mower can be moved to other positions.

The wheel hub 129 can rotate following the rotating shaft 111, thereby driving the outer ring 130 to rotate, so that the lawn mower can be moved to other positions.

[0025] The utility model relates to a lawn mower. When the lawn needs to be mowed, the clutch 121 is first tightened to start the motor 115 fixed on the top of the housing 101. The output end of the motor 115 drives the connecting shaft 116 to rotate, so that the cutter 118 at the bottom of the connecting shaft 116 rotates accordingly to mow the lawn. When the connecting shaft 116 rotates following the output end of the motor 115, the main gear rotates accordingly, and the belt 119 provided on the main pulley 117 can drive the secondary pulley 120 to rotate. The fixed shaft 123 can rotate following the secondary pulley 120 and drive the upper bevel gear 124 to rotate, so that the lower bevel gear 126 meshing with it rotates accordingly. As the mounting shaft 125 rotates, the transmission sub-gear 127 is driven to rotate, so that the transmission main gear 128 meshing with the transmission sub-gear 127 starts to rotate, driving the transmission shaft 106 to rotate. When the adjusting sub-gear 113 rotates following the transmission shaft 106, the adjusting main gear 112 meshing therewith can rotate accordingly, so that the rotating shaft 111 rotates, and the wheel hub 129 can rotate following the rotating shaft 111, thereby driving the outer ring 130 to rotate, so that the lawn mower can be moved to other positions. When mowing the lawn, the staff can adjust the clutch 121 according to the use needs to realize the gear shifting operation, and then adjust the speed of the cutter 118. In the event of an accident When the situation arises, the staff can operate the clutch 121 to switch to a low-speed gear. At this time, the speed of the output end of the motor 115 is reduced, and when the connecting shaft 116 is combined with the speed of the output end of the motor 115, the clutch 121 can achieve auxiliary braking through the speed difference between the output end of the motor 115 and the connecting shaft 116, so that the tool 118 stops rotating, thereby improving the safety of the staff when mowing the lawn. When the mowing height of the lawn needs to be adjusted according to the mowing requirements, the staff holds the paddle 108, slides the sealing plate 109 out of the groove on the height adjustment plate 110, and drives the sleeve 107 to move, changing the tangent angle between the sleeve 107 and the housing 101. At the same time, the shaft sleeve 107 is driven to move away from the shaft 111 at one end of the paddle 108, and the adjusting main gear 112 follows the shaft 111 to move on the adjusting sub-gear 113, so that the mounting shell 114 moves accordingly, and drives the tire 105 to move, changing the tangent angle between the tire 105 and the shaft sleeve 107, so as to adjust the height of the housing 101 from the ground. After the adjustment is completed, the sealing plate 109 is slid into the corresponding groove on the height adjustment plate 110 again, so that the mowing mechanism 102 is adjusted accordingly, and the mowing height of the lawn can be adjusted, thereby solving the problem that the existing lawn mower has a fixed mowing height when mowing the lawn, resulting in the inability to adjust the lawn mowing height according to different lawn mowing needs.The problem of adjusting the cutting height of a lawn mower.
