The rubber cover plate 52 is provided with a pressing protrusion 522, which is arranged opposite to the pressing switch. The pressing member 7 is adapted to press on the pressing switch through the pressing protrusion 522. When the user presses the pressing member 7 through the connecting member 42, the pressing member 7 triggers the pressing switch through the pressing protrusion 522, so as to make the circuit mainboard 51 send a first gear shifting signal to the whole vehicle. After the user separates from the connecting member 42, the pressing protrusion 522 resets and rebounds, so as to reset the connecting member 42 and the pressing member 7. When the user rotates the rotating member 3 through the outer cylinder 41, the relative position between the magnet 6 and the circuit mainboard 51 changes, so as to make the circuit mainboard 51 send a second gear shifting signal to the whole vehicle, i.e. the circuit mainboard 51 sends a brake signal of a corresponding gear position to the whole vehicle according to the change of the magnetic flux of the induction magnet 6.

[0080] In the embodiment, the circuit mainboard 51 is a PCB board. The PCB board is provided with a Hall chip for sensing the change of the magnetic flux of the magnet 6. The cooperation between the PCB board and the magnet 6 is prior art, which is not described herein.
