[0019] Hereinafter, embodiments of a garden mower with adjustable cutting height according to the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-3The utility model shows an adjustable cutting height garden mower according to an embodiment of the present invention, which comprises a body 1: two symmetrical rollers 8 are installed on the front and rear sides of the body 1, a handle 9 is fixedly installed on the left side of the body 1, a round shell 2 is arranged at the bottom of the body 1, a motor 3 is embedded and fixedly installed on the top of the body 1, the output shaft of the motor 3 passes through the inner cavity of the round shell 2 and a turntable 4 is fixedly installed, a turn pin 5 is fixedly connected to the bottom of the turntable 4, a blade body 6 is slidably connected to the surface of the turn pin 5, two symmetrical limit bars 10 are fixedly connected to the surface of the turn pin 5, the inner cavity of the blade body 6 is provided with two limit grooves 11 adapted to the limit bars 10, an adjustment component 7 is arranged between the blade body 6 and the body 1, the adjustment component 7 comprises a rotating column 71 fixedly connected to the top of the blade body 6 and slidably connected to the surface of the rotating pin 5, a rotating groove 72 is arranged on the surface of the rotating column 71, a triangular plate 73 is rotatably connected to the inner cavity of the rotating groove 72, and a rotating column 71 is fixedly connected to the top of the body 1. A U-shaped frame 74 is connected, and a threaded column 75 is fixedly connected to the top of the triangular plate 73. The top of the threaded column 75 passes through the top of the U-shaped frame 74. A threaded sleeve 76 is rotatably connected to the top of the U-shaped frame 74. The threaded sleeve 76 is threadedly connected to the surface of the threaded column 75. A plurality of operating holes 77 are provided in a circular array on the surface of the threaded sleeve 76. Through the setting of the operating holes 77, the user can insert the steel bar into the inner cavity of the operating hole 77 to operate the threaded sleeve 76, which provides a force point for the user to operate the threaded sleeve 76, and facilitates the user to operate the threaded sleeve 76. The front and rear sides of the top of the triangular plate 73 are fixedly connected with guide columns 78. The top of the guide columns 78 passes through the top of the U-shaped frame 74 and is slidably connected to the U-shaped frame 74. Through the setting of the guide columns 78, the guide columns 78 slide on the U-shaped frame 74, which can guide and limit the triangular plate 73, thereby preventing the triangular plate 73 from rotating with the rotation of the threaded sleeve 76, thereby improving the stability of the triangular plate 73.

[0021] Working principle: When the utility model is used, the user picks up the steel bar and inserts it into the inner cavity of the operating hole 77 to operate the threaded sleeve 76 to rotate. The thread causes the threaded column 75 to move up and down. The threaded column 75 drives the triangular plate 73 to move up and down under the limit of the guide column 78. The triangular plate 73 drives the blade body 6 to move up and down on the surface of the rotating pin 5 through the rotating column 71 to adjust the height of the blade body 6. When mowing the grass, it is only necessary to start the motor 3 to drive the turntable 4 and the rotating pin 5 to rotate. The limiting strip 10 on the rotating pin 5 cooperates with the limiting groove 11 on the blade body 6, thereby driving the blade body 6 to rotate for mowing the grass, and the blade body 6 drives the rotating column 71 to rotate stably in the inner cavity of the triangular plate 73.

[0022] To sum up: the garden mower with adjustable cutting height is operated by rotating the threaded sleeve 76. Due to the thread, the threaded column 75 drives the triangular plate 73 to move up and down. The triangular plate 73 drives the blade body 6 to move up and down on the surface of the rotating pin 5 through the rotating column 71 to adjust the height of the blade body 6. When mowing, it is only necessary to start the motor 3 to drive the turntable 4 and the rotating pin 5 to rotate. The rotating pin 5 drives the blade body 6 to rotate for mowing, and the blade body 6 drives the rotating column 71 to rotate stably in the inner cavity of the triangular plate 73, so as to achieve the purpose of being able to meet the needs of mowing at various heights and having strong applicability.
