         6 . The vibrating ripper of  claim 1 , comprising the rotating member in which at least one elastic body is installed between the vibrating body and the main body portion. 
     
     
         7 . A vibrating ripper comprising:
 a main body portion;   a vibrating body coupled to the main body portion and a vibrating body support unit and configured to vibrate;   a vibration generating unit installed at the vibrating body; and   a ripper blade installed at the vibrating body,   wherein the vibrating body support unit includes a rotating member which is rotatably installed at the vibrating body or the ripper blade, first and second connecting members, both ends of which are rotatably connected to the main body portion and upper and lower sides based on a rotation center of the rotating member to support the vibrating body with respect to the main body portion, a sub-main body which is supported on the main body portion located at an upper side of the vibrating body by a first elastic support unit, a connecting member which extends from the vibrating body to the inside of the sub-main body, and a rotating shaft which is supported by the sub-main body and rotatably installed at the connecting member.   
     
     
         8 . The vibrating ripper of  claim 7 , wherein an eccentric bearing is installed at a coupling portion between the connecting member and the rotating shaft installed at the sub-main body. 
     
     
         9 . The vibrating ripper of  claim 7 , wherein a first elastic member is installed between an upper side of the vibrating body of the connecting member and the sub-main body corresponding thereto, and a second elastic member is installed between an upper surface of the sub-main body and the main body portion or between a side surface of the sub-main body and the main body portion corresponding thereto. 
     
     
         10 . A vibrating ripper comprising:
 a main body portion;   a vibrating body coupled to the main body portion and a vibrating body support unit and configured to vibrate;   a vibration generating unit installed at the vibrating body; and   a ripper blade installed at the vibrating body,   wherein the vibrating body support unit includes a sub-main body which is installed at an upper side of the vibrating body by a first elastic support unit, a shaft support portion which extends from the vibrating body toward the sub-main body, a rotating member which is rotatably installed at a vibrating body support unit, first and second connecting members, both ends of which are rotatably connected to the main body portion and upper and lower sides based on a rotation center of the rotating member, and a stopper which is installed at the vibrating body bracket or the sub-main body to limit a rotating position of the rotating member.
