Description

Technical Field

[0001] The utility model relates to the technical field of electric pickaxes, in particular to an anti-splashing device. Background Art

[0002] The electric pick is a double-insulated handheld power tool powered by a single-phase series-excited motor. It is safe, reliable, efficient and easy to operate. It is widely used in pipeline laying, machinery installation, water supply and drainage facility construction, interior decoration, port facility construction and other construction projects. It is suitable for crushing, leveling, excavating, grooving and cutting concrete, masonry structures and asphalt pavements with a pick or other appropriate accessories such as a chisel and a shovel.

[0003] The existing Chinese patent with patent publication number CN211362142U discloses an electric pick that is splash-proof, including a shell, an electric pick head, a battery for driving the electric pick head, and a hand-held part. The electric pick head is arranged at the front end of the shell, and the battery is arranged inside the shell. A protective cover is arranged on the shell between the hand-held part and the electric pick head to prevent splashes from injuring workers. The protective cover can block splashes flying toward the construction workers, thereby effectively preventing splashes from flying in the direction of the construction workers, eliminating the safety hazards caused by splashes to the construction workers, and protecting the construction workers.

[0004] The above-mentioned anti-splash device for electric pickaxes prevents splashes from flying towards the direction of the construction workers by providing a protective cover. However, during use, the protective cover is fixed on the electric pickaxe at a certain height from the ground. When used on uneven ground, the protective cover cannot be adjusted, which affects its use and is not conducive to use on uneven ground. Therefore, the present application provides an anti-splash device to meet the needs. Utility Model Content
