The present invention relates to
fishing supplies, specifically an adjustable
buoyancy fishing float. At present, when faced with lead sinkers, fishhooks and baits of different weights,
fishing floats sometimes fail to float, or float up excessively high, making it difficult to determine whether a fish has bitten. The objective of the present invention is to provide an adjustable
buoyancy fishing float that provides a relatively wide
buoyancy adjustment range and eliminates the need for lead trimming during float adjustment. The technical solution of the present invention is as follows: comprising a float
tail, a float body, a float foot, etc. A cylinder, a
piston, a
piston ring, etc. are provided within the float body; the
piston is connected to the float
tail, and a penetrating through-hole runs from the float body, through the cylinder, the piston, etc. to the float
tail. The volume of the cylinder can be adjusted by pressing or pulling the float tail, the float tail having scale numbers marked thereon. Two ends of the cylinder inside the float body are filled with a lightweight material. A sealing
gasket is provided at the contact point between the float tail and the float body to prevent water from entering the cylinder. In a luminous float based on the present adjustable buoyancy fishing float, a battery compartment, a luminous light, etc. are arranged on the float tail. The present invention has the beneficial effects of providing a relatively wide buoyancy adjustment range, involving simple buoyancy adjustment, and eliminating the need for lead trimming during float adjustment.
