The grabbing device for the small holes and the cracks is characterized in that the state of being opened or closed and the shaped of the claw are controlled by a stretching handle to perform the function of grabbing an article. The telescopic rod is connected with the claw. Parts of the telescopic rod are fixed together through clamping grooves to control the length of the extended portion of the claw. The opening and closing of the claw is achieved by controlling the extending and contracting of the intermediate shaft through pulling a pull ring (similar to the principle of opening and closing of an umbrella).
