[0002] When carrying out concrete crushing operations in cities, safety isolation areas and facilities must be set up in advance; usually, operators designate a certain range as a restricted area during operations to prevent concrete blocks from splashing and injuring people during crushing; hydraulic breaker is referred to as "breaker" or "breaker". The power source of the hydraulic breaker is the pressure provided by the excavator, loader or pump station. It can more effectively crush stones and rocks during construction and improve work efficiency.

[0004] At present, hydraulic breakers are mainly installed on mechanical devices to break stones. Their working principle is relatively simple. They mainly use the reciprocating cycle of the piston to drive the drill rod to extend and retract, so that the end of the drill rod hits the stone to break the stone. However, the existing breakers usually cause fragments to splash due to the impact during the crushing process, which can easily injure the surrounding workers, thereby forming a safety hazard. Although the above-mentioned method can effectively prevent the splashing of broken stones from injuring people, it hinders the line of sight of the crushing position of the breaker, making it impossible for the driver to timely understand the specific actual situation of the crushing position.
