Description

Technical Field

[0001] The utility model relates to the technical field of trimmers, and in particular to a gardening trimmer. Background Art

[0002] Landscaping is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, by transforming the terrain (or further building mountains, stacking stones, and managing water), planting trees, flowers, and plants, creating buildings, and arranging garden paths. In daily maintenance, the grass in the garden often needs to be trimmed with a grass trimmer; however, most of the existing grass trimmers are handheld, and the operator needs to hold the trimmer, and the operator cannot trim the grass for a long time, resulting in reduced efficiency in grass trimming.

[0003] After searching, China disclosed a gardening lawn mower with patent publication number CN214852840U on November 26, 2021. It is roughly described as including a lifting seat and a base. The lifting seat is arranged above the base, and a screw rod is threadedly inserted at one end of the top of the lifting seat. The screw rod passes through one end of the lifting seat and is rotatably connected to the base. A first groove is provided on the top of the base. The utility model is a gardening lawn mower with a simple structure and is easy to use. The servo motor is fixedly installed in a protective box on the top of the lifting seat, and multiple support frames are fixedly connected to the rotating shaft of the servo motor to support the steel cable. The lifting seat is supported by screw rods and limit rods at both ends of the top of the base. The universal wheel at the bottom of the base can be pushed to move along the grass through the handle, and the distance between the lifting seat and the base can be adjusted by rotating the screw rod, so that the servo motor installed on the top of the lifting seat can drive the steel cable to rise and fall, thereby adjusting the height at which the steel cable can mow the grass.

[0004] Although the above-mentioned prior art solution can adjust the height of the mowing grass, the device uses steel cables to mow the grass. Although it can prevent the equipment from being damaged when it collides with stones, the steel cables have poor mowing effect on tougher grass and can easily break the grass leaves, causing an unsightly appearance and reducing the mowing effect of the equipment.
