| description | The invention relates to a breaking hammer and aims to solve the problems that an existing electric breaking hammer is complex in transmission structure and low in transmission efficiency. The electric breaking hammer comprises a cylinder body, a drill rod, a piston rod and an electromagnetic driving device, the drill rod is mounted in the cylinder body, one end of the drill rod extends out of the cylinder body, the piston rod is mounted in the cylinder body, can reciprocate and is used for striking the drill rod, a magnetic attraction part is arranged on the piston rod, and the electromagnetic driving device comprises a controller, a sensor and an electromagnet, the sensor is used for detecting the axial position of the piston rod; the controller drives the electromagnet according to the axial position of the piston rod to generate a magnetic field which interacts with the magnetic attraction part on the piston rod to enable the piston rod to move axially. In the invention, the piston rod is driven by the el |
