Abstract: Disclosed is a magnetic braking mechanism which includes a spool, a magnetic braking assembly arranged on a side of the spool, the magnetic braking assembly includes a magnet assembly for generating magnetic induction lines and a centrifugal adjusting assembly for automatically adjusting a spacing between the magnet assembly and an inner wall of the spool according to a rotation speed of the spool, so as to adjust range of the magnetic induction lines cut by the spool, thereby automatically adjusting magnitude of a braking force. The centrifugal adjusting assembly allows the magnet assembly to move close to or away from the inner wall of the spool in the radial direction, so as to control strength of the magnetic induction lines near the inner wall of the spool, thereby adjusting the magnitude of the breaking force. Further disclosed are a bait casting reel and a fishing tool.

Abstract: The present disclosure disclosed a magnetic braking mechanism which includes a spool, a magnet assembly arranged on a side of the spool for generating magnetic induction lines, and a magnetic braking assembly connected to the spool and including at least two metal plates and a centrifugal adjusting assembly. The metal plates are disposed between the magnet assembly and the spool, and the centrifugal adjusting assembly is used for automatically adjusting spacing between the metal plates and an axis of the spool according to a rotation speed of the spool, so as to adjust range of the magnetic induction lines cut by the metal plates, thereby automatically adjusting magnitude of a braking force. Further disclosed are a baitcast reel and a fishing tool.

Abstract: A compensatory magnetic brake structure includes a line reel rotatably, a fixed magnet fixedly provided on a side of the line reel, a moving magnet rotatably provided on a side of the fixed magnet, an adjusting assembly for driving the moving magnet to rotate in order to adjust the corresponding range of a magnetic pole between the moving magnet and the fixed magnet, at least one set of magnetic piece movably provided between the moving magnet and the fixed magnet, and a centrifugal assembly automatically adjusting the distance between the magnetic piece and the axis of the line reel according to the speed of the line reel. The disclosure provides a compensatory magnetic brake structure with good brake stability and automatically compensatory brake function.
