The invention relates to
fishing supplies, in particular to a
buoy with adjustable
buoyancy. At present, when facing lead weights, fishhooks and baits with different weights,
fishing buoys cannot float or float too much sometimes, and whether fishes are fished or not is not attractive. The invention aims to provide the
buoyancy-adjustable
buoy which is relatively large in
buoyancy adjustment range and does not need to shear a lead sheath during
buoy adjustment. According to the technical scheme, the float comprises a float
tail, a float body, a float foot and the like. A cylinder, a
piston, a
piston ring and the like are arranged in the float body, the
piston is connected with the float
tail, and a through hole is formed from the float body to the float
tail through the cylinder, the piston and the like. The volume of the air cylinder can be adjusted by pressing or pulling the float tail, and scale numbers are marked on the float tail. Two ends of the cylinder in the float body are filled with light materials. A sealing
ferrule is arranged at the
contact position of the float tail and the float body to prevent water from entering the cylinder. According to the floating buoy with the adjustable buoyancy, the battery bin, the luminescent lamp and the like are arranged on the buoy tail.
