It is an automatic that allows convenient and easy fishing because the fish''s bite expression that occurs in the underwater bottom is reliably displayed on the bottom by maintaining a constant knob of the chisaw that appears on the surface according to the action of buoyancy and sedimentation and changes in the underwater bottom during fishing. There are fishing floats for depth customization. The float according to the present invention passes through the water surface floats with buoyancy that flows vertically along the floats and the fishing line lead ring that guides the fishing line to life in the center of the floats, offsetting the buoyancy of the core force body with the weight of the lower poles The fishing line rod tube that keeps the sieve in the water is located, the fishing line passes through the fishing line rod tube that guides the fishing line vertically, and the fishing line passes into the inside of the central force body and is installed at the bottom of the chisaw to rise when the central force body rises. A fishing line lead hook that guides the fishing line horizontally and a fishing line that guides the fishing line horizontally when the second stick passes through the fishing line guide hook installed to maintain the smooth function of the control stopper and reaches the water. When the central force body descending along the lower end of the chisaw by the friction force of the rod tube rises due to the offset of the frictional force, the central force body rise control stopper installed under the fishing line lead ring of the chisaw and the central force body tube 122 The fishing line 130 is bent in an a-shape, so that the rise of the central force body is controlled at a certain point, so that the chisaw displayed on the water surface is constantly displayed so that it is easier to recognize, and unlike the conventional ones, the first and second Bongdol is different from the expression of jji that appears in the diagonal arrangement of t
