As described above, in this embodiment, the mounting pin 61 can be easily attached and detached when the bucket is replaced. Since the hydraulic cylinder 2 is provided on the table 10 of the carriage 1 which can be moved up and down, at any place,
It is possible to easily align the axes of the hydraulic cylinder 2 and the mounting pin 61 with each other in any size excavator. The link chain 3 for receiving the reaction force is easy to fit in the bracket shape and is well locked for safety, and since the length can be freely adjusted, the work can be efficiently advanced. The rotating base 5 rotates in accordance with how the link chain 3 is applied to the bracket 60, and makes the tension direction of the link chain coincide with the axial center of the hydraulic cylinder 2. Therefore, an eccentric force does not act during pressurization. You can work safely. Since a hydraulic cylinder is used, the structure is simple,
Further, since the applied pressure can be monitored by the hydraulic pressure gauge, the replacement work can be performed without applying an excessive force to each part.
Even if there is a step between the through hole 63 of the arm 64 and the mounting hole 62 of the bucket 6, by using the guide pin,
The mounting pin 61 can be easily attached.
