DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As mentioned in the background technology, the inclination angle between the handle and the machine body is fixed in the prior art, which makes it inconvenient to use the handle to move the machine body when mowing on a slope, and the user often needs to raise his arm to grab the handle. The present invention provides a lawn edge mower with multi-angle adjustment.

[0032] Example 1

[0033] Reference Figures 1 to 4 , a lawn edge cutter with multi-angle adjustment, comprising, a fixing frame 1;

[0034] A splash-proof tube 2 is provided at the bottom of the fixed frame 1 to prevent stones from collapsing and injuring people when mowing the grass;

[0035] A motor is arranged in the fixing frame 1, and a mowing blade located in the splash-proof cylinder 2 is arranged on the output shaft of the motor;

[0036] A shock absorbing device 1 is provided on the top of the fixing frame 1;

[0037] A mounting frame 11 is provided on the first shock absorbing device, and the mounting frame 11 is a U-shaped structure;

[0038] The mounting frame 11 is connected to a round shaft 3 via a bearing, and the round shaft 3 is connected to a handle 4, so that the handle 4 can be rotated by the round shaft 3 to adjust the angle;

[0039] The handle 4 is provided with a control button electrically connected to the motor for controlling the motor;

[0040] An adjusting device is provided at the front end of the circular shaft 3 , and the adjusting device is used to adjust the inclination angle of the handle 4 .

[0041] The adjusting device includes a gear 5 arranged at the front end of the circular shaft 3, and a vertical rack 6 is meshed and connected on the right side of the gear 5. A guide rod 7 vertically penetrates the vertical rack 6, and a mounting block 8 is arranged at the bottom of the guide rod 7. The rear side of the mounting block 8 is arranged on the mounting frame 11. The vertical rack 6 is raised and lowered on the guide rod 7, so that the gear 5 rotates, thereby driving the circular shaft 3 to rotate.

[0042] In order to make the vertical rack 6 able to be raised and lowered, a screw rod 9 is rotatably connected to the top of the mounting block 8 through a bearing, the vertical rack 6 is screwed to the outside of the screw rod 9, a hand wheel 10 is provided on the top of the screw rod 9, and the hand wheel 10 is located above the guide rod 7 and is not hindered by the guide rod 7 when rotating. The screw rod 9 is driven to rotate by the hand wheel 10, so that the vertical rack 6 can be raised and lowered.

[0043] A reinforcement device is provided at the front right end of the mounting frame 11 , and a threaded rod 13 is provided at the right end of the vertical rack 6 .

[0044] The reinforcement device includes a slide rail 12, which is slidably connected to the vertical rack 6. The slide rail 12 is arranged at the front right end of the mounting frame 11. A through slot 14 is vertically opened on the right side of the slide rail 12. The threaded rod 13 extends to the right side of the slide rail 12 through the through slot 14, so that when the vertical rack 6 is raised or lowered, the threaded rod 13 can be raised or lowered at the through slot 14. A nut 15 is screwed on the threaded rod 13, and an anti-slip pad 16 that is affixed to the slide rail 12 is fitted on the left side of the nut 15. After adjusting the position of the vertical rack 6, the nut 15 is rotated on the threaded rod 13 to press the anti-slip pad 16 against the right side of the slide rail 12. By increasing the friction force, the reinforcement of the position of the vertical rack 6 is improved, thereby improving the stability of the handle 4 when in use.

[0045] The vibration generated when mowing the lawn will be transmitted to the mounting frame 11. Long-term vibration will cause the handle 4 to loosen. Therefore, a shock absorbing device 1 is provided, wherein the shock absorbing device 1 includes a connecting box 17 arranged on the top of the fixing frame 1. The side walls of the connecting box 17 and the bottom inner wall of the connecting box 17 are all provided with an outer tube 20. The inner wall of the outer tube 20 is fitted with a rubber tube 22. The rubber tube 22 is arranged on the outside of the connecting rod 19. The connecting rod 19 is provided with a spring 21 located in the outer tube 20. The spring 21 is connected to the connecting box 1 7, the middle connecting rod 19 is arranged on the bottom of the mounting frame 11, and the middle connecting rod 19 and the surrounding connecting rods 19 are hinged with inclined rods 23. When vibrating, the mounting frame 11 rises and falls, so that the middle connecting rod 19 compresses the middle spring 121 and drives the middle rubber tube 122 to slide in the middle outer tube 20, and the inclined rod 23 drives the surrounding connecting rods 19 to move horizontally, compresses the surrounding springs 121, and makes the surrounding rubber tubes 12 slide in the surrounding outer tubes 20, so that the vibration of the mounting frame 11 can be weakened.

[0046] Slide grooves 18 slidably connected to the mounting frame 11 are provided on both sides of the interior of the connection box 17. The connection box 17 slides and fits inside the connection box 17, so that the mounting frame 11 can be stably raised and lowered during vibration. In order to improve the shock absorption capability, shock absorbing devices 2 are provided around the bottom of the mounting frame 11.

[0047] Example 2

[0048] Reference Figures 4 to 5The second shock absorbing device includes a connecting tube 24 arranged on the bottom of the mounting frame 11, and the connecting tube 24 is slidably sleeved on the vertical rod 25. The bottom of the vertical rod 25 is connected to the bottom inner wall of the connecting box 17, and a spring 26 is arranged on the bottom inner wall of the connecting box 17. A rubber tube 27 is arranged on the outer wall of the connecting tube 24. An outer tube 28 connected to the inner wall of the connecting box 17 is arranged on the outside of the rubber tube 27, and the spring 26 is located inside the outer tube 28. When the mounting frame 11 moves downward, the surrounding connecting tubes 24 slide on the vertical rod 25, and the spring 26 is compressed, so that the rubber tube 27 slides in the outer tube 28, thereby weakening the vibration through friction resistance. The bottom middle position and the surrounding areas of the mounting frame 11 can be shock-absorbing, which greatly improves the shock absorption strength to avoid the position movement of the vertical rack 6, which causes the problem of weak stability of the handle 4.

[0049] The rest of the structure is the same as that of Example 1.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
