[0004] To solve the above technical problems, the purpose of the present application is to provide a garden edge trimmer which can remove grass roots and improve trimming effect.

[0005] The technical solution adopted by the present application to solve the problem is:

[0006] A garden edge trimmer, comprising a rack, the lower end of the rack is fixedly connected with a central shaft;

[0007] A guide wheel, which is rotatably connected to the central shaft;

[0008] A rolling gear, which is rotatably connected to the central shaft, is fixedly connected with the guide wheel and rotates coaxially, and is arranged on the inner side of the rolling gear;

[0009] A knife holder, which is rotatably connected with the central shaft, is arranged on the outer side of the rolling gear, and the lower end of the knife holder is provided with a blade;

[0010] When the rolling gear rotates, the tooth groove of the rolling gear can rotate from the inner side of the blade edge;

[0011] The outer diameter of the guide wheel is smaller than the outer diameters of the rolling gear and the blade.

[0012] By setting the rolling gear and the blade, and the rolling gear is relatively sharp, when the edger works, the rolling gear and the blade can be inserted into the soil, in the rolling process of the rolling gear, the teeth can drive the plants in the tooth groove to turn beside the blade, and the blade is used to cut the roots of the plants, so that the roots of the plants are removed, so that the lawn edge is better trimmed clean; and the edger does not need to use an external power source, and the cost is low.

[0013] As a further improvement of the above technical solution, the upper part of the blade holder is provided with a mounting hole and a counterbore hole;

[0014] Further comprising an adjusting device, the adjusting device comprises an adjusting screw and a knob, the knob is arranged outside the rack;

[0015] The outer end of the adjusting screw passes through the mounting hole and the rack and is screwed with the knob, the head of the adjusting screw is blocked at the back side of the upper end of the blade holder, a first spring is sleeved on the adjusting screw, and the first spring is arranged between the rack and the blade holder;

[0016] The counterbore hole is arranged below the mounting hole, a second spring is arranged between the counterbore hole and the rack, and the second spring is sleeved on the central shaft.

[0017] By setting the adjusting device, the edger can meet different trimming needs. When the knob is tightened, the first spring is compressed, and since the size of the second spring is larger than that of the first spring, the blade is pushed away from the rack, and the distance between the blade and the rolling gear is smaller, and the trimmed plants are shorter; when the knob is loosened, the upper part of the blade holder is pushed away by the elastic force of the first spring, and at this time, the distance between the blade and the rolling gear is larger, and the trimmed plants are longer, so that the edger has multiple functions.

[0019] The rear side wall of the tool holder is punched and formed with a second recess communicating with the first recess, the depth of the second recess is greater than the depth of the first recess, so that the outer wall of the tool holder is close to the frame and there is a gap between the outer wall of the tool blade and the frame, the second recess is only located at the bottom of the tool holder, and the bottom of the tool holder and the bottom of the second recess are both arc-shaped; The main resistance of the garden edger in the running process comes from the resistance of pushing the tool holder and the tool blade forward to form a groove in the soil, the first recess is arranged to make the tool blade have a certain thickness, so that a groove can be formed in the soil during the pushing of the tool blade, and the first recess punched on the tool blade can improve the strength of the tool blade and avoid deformation of the tool blade; Since the frame does not insert into the soil, the second recess also basically does not generate resistance to the pushing of the tool blade.

[0020] The tool blade is integrally formed with the tool holder to increase the strength of the tool blade and the tool holder, and avoid deformation of the tool blade during cutting a groove in the soil.

[0021] The rolling gear is in a thin plate shape, the thin plate-shaped teeth can be easily inserted into the soil, reducing the resistance of pushing the garden edger, the outer end of the tooth of the rolling gear is located on the same circular arc as the outer end of the tool blade, the tooth is triangular, the outer wall of the rolling gear is in contact with the tool edge, and the depth of the tooth groove is less than the depth of the tool edge. All plants in the tooth groove can be in contact with the tool edge to be cut off.

Setting the included angle between adjacent teeth in a smaller range can reduce the width of the tooth groove, so as to avoid that the shorter root system is removed from the tooth groove before encountering the tool edge for cutting during the rotation of the tooth groove. The included angle between the tool blades affects the height of the tool blades, and the included angle is too large to cause the tool edge to be unable to be completely inserted into the soil.

[0023] As a further improvement of the above technical solution, the thickness of the gear is less than the thickness of the tool blade, and the thinner the tooth, the better the shearing effect of the tooth interacting with the tool blade.

[0024] As a further improvement of the above technical solution, the guide wheel comprises a first guide wheel and a second guide wheel, and the first guide wheel and the second guide wheel are both rotationally connected with the center shaft through a sliding sleeve.

[0025] The first guide wheel and the second guide wheel are hollow cylindrical structures, and a splicing cylinder is arranged in the inner cavity of the first guide wheel and the second guide wheel, and the first guide wheel and the second guide wheel are spliced and coaxially rotated. By arranging two guide wheels, the trimmer can adapt to more terrains and be more stable during use.

[0026] As a further improvement of the above technical solution, the rolling gear is rotationally connected with the center shaft through the sliding sleeve. The contact area of the rolling gear and the center shaft is increased, and the stability of the connection between the rolling gear and the center shaft is enhanced.

[0027] As a further improvement of the above technical solution, the first guide wheel and the second guide wheel are externally provided with anti-skid teeth, the first guide wheel and the second guide wheel are each externally sleeved with a tire, and the outer sidewall of the tire is provided with anti-skid lines. The stability of the guide wheel is enhanced, the guide wheel is prevented from slipping to cause the trimmer to be unable to be used, and the user is prevented from falling and being injured during use.

[0028] As a further improvement of the above technical solution, the rack includes a first rack and a second rack, the upper end of the first rack and the upper end of the second rack are connected through fasteners, the lower ends of the first rack and the second rack are arc-shaped, and the guide wheel, the rolling gear and the tool holder are arranged between the lower ends of the first rack and the second rack. The rack can be split and spliced, and workers are facilitated to package, transport and install.

[0029] The beneficial effects of the present application are: by arranging the rolling gear and the blade, and the teeth of the rolling gear are relatively sharp, when the trimmer works, the rolling gear and the blade can be inserted into the soil, in the rolling process of the rolling gear, the teeth will drive the plants in the tooth groove to rotate beside the blade, the blade is used to cut the plant roots to remove the plant roots, so that the lawn edge is better trimmed clean; and the trimmer does not need to use an external power source, and the cost is low.
