Electric hammer is a widely used electric tool. An electric hammer is based on an electric drill, which adds a piston driven by an electric motor with a crankshaft connecting rod. It compresses air 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 strike the top of the drill bit back and forth, which is equivalent to using a hammer to strike the drill bit, hence the name electric hammer.

Electric hammer is a type of electric drill mainly used for drilling holes in concrete, floor slabs, brick walls, and stone. Specializing in drilling holes on walls, concrete, and stone, as well as adjusting the multifunctional electric hammer to the appropriate position with a suitable drill bit, it can replace ordinary electric drills and pickaxes.

Due to the rapid reciprocating motion (frequent impact) of the drill bit along the direction of the drill rod while rotating, the electric hammer can quickly drill holes in brittle materials such as cement concrete and stone. The high gear electric hammer can use a switch to put the drill bit of the hammer in different working states, that is, only rotating without impact, only impacting without rotation, both impacting and rotating.

characteristic

1. A good shock absorption system: can make the operator feel comfortable to hold and relieve fatigue. Implementation approach: achieved through a vibration control system; increased grip comfort through soft rubber handles;

2. Accurate speed control switch with low speed when lightly touched can help the machine smoothly start drilling (for example, on smooth surfaces such as tiles, starting drilling can not only prevent the drill from slipping, but also prevent drilling from breaking. High speed can be used during normal operation to ensure work efficiency.

3. Motor protection device: During use, it is inevitable that granular hard objects will enter the machine (especially when drilling holes upwards, such as on the top of walls). If the motor does not have certain protection, it is easy to be broken or scratched by hard objects during high-speed rotation, resulting in motor failure.

4. Forward and reverse rotation function: It can make the application range of the electric hammer more extensive. Its implementation form is mainly achieved by switching or adjusting the position of the carbon brush. Usually, good tools will use adjusting the position of the carbon brush (rotating the brush holder) to achieve this. The advantage of doing so is that it is easy to operate and effectively controls the spark to protect the commutator, extending the service life of the motor

5. Hammer drill dual function
