The difference between an electric hammer and an electric hammer is that an electric rotary hammer drill with a safety clutch is equipped with a pneumatic hammer mechanism. The electric hammer utilizes the principle of piston motion to compress gas and impact the drill bit. It does not require much force from hand and can drill holes of 6-100mm on hard materials such as concrete, bricks, and stones. The electric hammer has a higher efficiency in drilling on these materials, but it cannot drill holes on metal. Electric hammers are suitable for drilling holes in hard building materials such as concrete and masonry. The electric hammer is powered by a single-phase series excited motor. Equipped with rotary impact, single rotation and single function, single rotation and single rotation impact are suitable for drilling on brittle materials such as concrete, rock, brick masonry, porcelain, etc. Single impact can be used to excavate and excavate trenches on concrete and brick walls. The shovel situation, electric hammer power, and processing ability are strong. The drilling diameter is usually between 12-50mm, and different working heads can be selected for various operations. Easy to operate, high drilling accuracy, electric hammers generally have overload protection devices, which can automatically slip when the mask is overloaded or the drill bit is stuck, without causing the motor to burn out. For electric hammers with a center size of 23mm or less, they are generally made into an adjustable structure with a hammer drill and only two rotating gears. Some small and medium-sized electric hammers have forward and reverse rotation functions, which can be used as electric screwdrivers. For larger electric hammers, not only are they equipped with hammer drilling functions, Some electric hammers are equipped with an impact gear without rotation, and the working head of the electric hammer can be used as an electric hammer. 2. The electric pick is operated in a bouncing manner by the electric motor driving the swinging weight, which produces the effect of chiseling the ground with the pick. The pump hammer in the electric pick bounces back and forth, producing the effect of the pick chiseling on the ground, but the electric pick only chisels, and its pick does not rotate. Electric picks are mainly used for crushing, chiseling, excavating, cutting, concrete, bricks, stones, ice blocks, etc., in the assembly of pipelines. Laying cables, installing sanitary equipment, installing machinery, and providing water and drainage facilities. Indoor decoration, port facility construction, and other civil engineering construction have been widely used, and different forms of shovels, cutting heads, and carrying out different operations are needed. Widely used in the construction and decoration industry. The difference between electric picks and electric hammers is that electric picks have no rotation function, only impact function, and the impact energy is relatively large
