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: Disclosed is an integrated diaphragm pump, comprising a first stop plate (1), a foaming member (2), a valve plate (5), a diaphragm (7), and a motor (10), wherein the foaming member (2) comprises a gas-liquid mixing tank (21) and a foaming cavity, and an outlet of the gas-liquid mixing tank (21) is in communication with the foaming cavity for mixing a gas and a liquid and foaming same by means of the foaming cavity. The integrated diaphragm pump has the advantages of being high in integration and small in size.
