Foldable all-around drilling mechanism

The invention relates to a foldable all-around drilling mechanism which comprises a base plate, a turning oil cylinder, a turning frame, a slewing bearing, a guide rail and a power head, wherein the folding of the turning frame is controlled through the telescopic effect of a piston rod of the turning oil cylinder; one end of the slewing bearing is fixedly arranged on the turning frame; the otherend of the slewing bearing is connected with the guide rail; and the power head is arranged at the side, opposite to the side connected with the slewing bearing, of the guide rail. The foldable all-around drilling mechanism has the advantages that the structure is reasonable; the foldable all-around drilling mechanism has two states including a transportation state and a work state; the transportation requirements of a coal mine underground narrow roadway can be met; the machine dismounting transportation is avoided; the equipment fault probability caused by the assembly by unprofessional minepersonnel is effectively
