PURPOSE:To strongly attach the holder of clamp to the arm of back hoe even when different shapes of arms from different makers are used by attaching the holder of clamp to the arm of the back hoe in a freely detachable manner by using a bucket-fitting pin and patches for the upper and lower sides of the arm. CONSTITUTION:In attaching paired clamps 2 and 3 to the tip of the arm 7 of an excavator, e.g., back hoe, etc., for a bucket, the holder 4 of the clamps 2 and 3 is attached to the arm 7 by using a bucket-fitting pin 8 and a patch 6 for the upside of the arm 7 and a patch 5 for the lower side of the arm 7. By this, the conventional types of lever 24 and rod 23 can be used as such, and also even when different shapes of arms from different makers are used, the clamps can be attached to the arms easily and detachably by changing the fitting positions and the contact area of paired patches 5 and 6. |
