Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a portable electric hammer. Background Art

[0002] The electric hammer is an electric rotary hammer drill with a safety clutch and a pneumatic hammer mechanism. The electric hammer uses the principle of piston movement to compress the gas to impact the drill bit. It does not require much hand strength and can open 6-100mm holes in hard materials such as concrete, bricks, and stones. The electric hammer has a high efficiency in opening holes in the above materials, but it cannot open holes in metals. The electric hammer is a widely used power tool. The electric hammer is based on the electric drill, adding a piston with a crankshaft connecting rod driven by an electric motor. The air is compressed back and forth in a cylinder, causing the air pressure in the cylinder to change periodically. The changing air pressure drives the hammer in the cylinder to reciprocate and strike the top of the drill bit, which is equivalent to hitting the drill bit with a hammer. Hence the name electric hammer. The electric hammer is a type of electric drill, mainly used to drill holes in concrete, floor slabs, brick walls and stone. Professionally used for drilling holes on walls, concrete, and stone, there are also multifunctional electric hammers, which can replace ordinary electric drills and electric picks when adjusted to the appropriate position and equipped with appropriate drill bits. Since the drill bit of the electric hammer produces rapid reciprocating motion along the direction of the electric drill rod while rotating, it can quickly drill holes in brittle cement concrete and stone materials. High-end electric hammers can use a conversion switch to put the drill bit of the electric hammer in different working states, that is, only rotating without impact, only impacting without rotating, and both impacting and rotating. With the development of society, electric hammers are used when buildings need to be constructed.
