The subject innovation is to form a that, specifically, the cylinder length is adjusted to the hydraulic pump so as to adjust the inclination of the holding of the easy-to adjust the angle of the drilling tube bucket holding, and coupled to the inclined plate cylinder shaft projecting from the cylinder, Since it fixed to the swash plate for coupling the holding and drilling pipe to the top plate with a fixed pin, by a cylinder with a fixed pin on the basis is coupled to the holding formed in both sides of the operation, regardless of the operation of the crane fork beams diamond crown for excavators rock and therefore to adjust the contact angle, rocks and provided the angle of the drilling tube in contact with a wide range, it removes crushed rock at various angles only by angle adjustment of the excavator without the activation of the crane fork, narrow the activation of the crane fork uncomfortable space or, tilted position to remove tough job easy rock to a fixed and diggers It can be removed quickly, it was so effective that offers convenience and speed of work using an excavator. Rock crushers, excavators, rock breaker.
