[0011] Preferably, a movable block is rotatably connected to the circumferential side of the lead screw, the bottom of the movable block is slidably connected to the top outer wall of the movable frame, a rotating groove surrounding the lead screw is opened inside the movable block, a limiting ring surrounding the lead screw is rotatably connected between the inner walls of the two sides of the rotating groove, and the inner wall of the circumferential side of the limiting ring is fixedly connected to the circumferential side of the lead screw.

[0012] Preferably, a lifting groove is provided inside the top of the mobile frame, a lifting ring is slidably connected to the inner wall of the circumferential side of the lifting groove, a spring is fixedly connected between the bottom of the lifting ring and the bottom of the lifting groove, a lifting column is fixedly connected to the inner wall of the circumferential side of the lifting ring, and the top of the lifting column extends to the outer wall of the top of the mobile frame.

[0013] Preferably, the top inner wall of the movable frame is rotatably connected to a rotating ring aligned with the lifting column, the circumferential side of the limiting column is slidably connected to the inside of the rotating ring, the top of the rotating ring is provided with a slot aligned with the lifting column, the side of the movable block is fixedly connected to an extrusion plate aligned with the lifting column, the top and bottom of the extrusion plate are provided with an extrusion groove aligned with the lifting column, and the outer wall of the circumferential side of the fixed ring is fixedly connected to a fixed frame, one end of the fixed frame is fixedly connected to a handle.

[0014] Compared with the prior art, this utility model provides a lithium battery-powered long-handled lawnmower, which has the following beneficial effects:

[0015] The device is moved near a patch of shrubs using a movable frame, allowing the shrubs to extend into the frame through openings and slots. The motor is then started, driving a rotating shaft, which in turn rotates a limiting cylinder. This limiting cylinder, in turn, rotates a limiting post, which in turn rotates an arc-shaped blade. The arc-shaped blade cuts the vertical side of the shrubs extending into the frame. Rotating a lead screw moves a moving block, which in turn moves the movable frame, causing the circumferential side of the saw blade to extend beyond the frame. Simultaneously, the limiting post disengages from the limiting cylinder, disengaging the arc-shaped blade from the rotating shaft. The rotating shaft then rotates the saw blade, which cuts the shrubs... The horizontal cutting allows the device to adjust its cutting scheme according to the needs of cutting shrubs and grasses. This helps prevent users from accidentally cutting too much or too little shrubs and grasses when using the device to cut horizontally or vertically due to improper gripping and cutting. When the moving block moves, it drives the pressing plate to move, and the pressing plate presses the lifting column, causing the lifting column to lock into the slot. This helps to fix the curved blade in place and prevents the curved blade from moving abnormally during saw blade operation, which would affect the safety of the device. Attached Figure Description

A limiting post 21 is slidably connected to the inner wall of the circumferential side of the limiting cylinder 23. An arc-shaped blade 13 located outside the limiting cylinder 23 is fixedly connected to one end of the limiting post 21. The circumferential side of the arc-shaped blade 13 is slidably connected to the inner wall of the circumferential side of the movable frame 1.

[0024] A fixed cylinder 9 located at the top of the movable frame 1 is fixedly connected to the outer wall of the circumferential side of the fixed ring 6. A screw rod 12 is threadedly connected to the inner wall of the circumferential side of the fixed cylinder 9, and one end of the screw rod 12 extends to the outside of the fixed cylinder 9.

[0025] A movable block 10 is rotatably connected to the circumferential side of the lead screw 12. The bottom of the movable block 10 is slidably connected to the top outer wall of the movable frame 1. A rotating groove surrounding the lead screw 12 is opened inside the movable block 10. A limiting ring 11 surrounding the lead screw 12 is rotatably connected between the inner walls of the two sides of the rotating groove. The inner wall of the circumferential side of the limiting ring 11 is fixedly connected to the circumferential side of the lead screw 12.

[0026] The top of the mobile frame 1 has a lifting groove 19. A lifting ring 15 is slidably connected to the inner wall of the circumferential side of the lifting groove 19. A spring 22 is fixedly connected between the bottom of the lifting ring 15 and the bottom of the lifting groove 19.

Limiting post 21 drives curved blade 13 to rotate, cutting the vertical side of the bushes extending into the moving frame 1. Rotating screw 12 moves moving block 10, which in turn moves the moving frame 1, causing the circumferential side of saw blade 2 to extend out of the moving frame 1. Simultaneously, limiting post 21 disengages from limiting cylinder 23, disengaging curved blade 13 from shaft 7. Shaft 7 then drives saw blade 2 to rotate... When the saw blade 2 moves, it cuts the horizontal plane of the shrubs and grasses. This allows the device to adjust its cutting scheme according to the cutting needs of the shrubs and grasses. This helps prevent the user from accidentally cutting too much or too little shrubs and grasses when using the device to cut the horizontal or vertical plane of the shrubs and grasses because they cannot hold the device properly and cut the shrubs and grasses. This affects the cutting effect of the device. When the moving block 10 moves, it drives the pressing plate 16 to move. The pressing plate 16 presses the lifting column 17, so that the lifting column 17 is locked into the slot 20. This helps the device to fix the arc blade 13 and prevents the arc blade 13 from moving abnormally when the saw blade 2 is working, which would affect the safety of the device.
