PURPOSE: A joint structure of a bracket bending device for a hydraulic breaker is provided to facilitate the transportation, assembly, and installation works of a movable jig by producing the movable jig into a fixed size and continuously engaging the movable jigs and to reduce the production cost of a mold. CONSTITUTION: A joint structure of a bracket bending device for a hydraulic breaker comprises a bending device (100), a movable jig (30), a fixed jig (60), and a position fixing piece (70). The bending device includes a fixed block (10) and a movable block (20). The movable jig is installed on the movable block and includes a main body (40) and a fixing member (49). The fixing member fixes a pressurization part (46) which is detachably joined to the main body. The fixed jig is installed on the fixed block. The position fixing piece is installed on the fixing groove (21) of the movable block and the supporting groove (54) of a fixing plate (53). |
