The invention discloses a gear shifting device and a marine propeller, and relates to the technical field of marine machinery, the gear shifting device comprises a clamping base, a rotating mounting seat is rotatably arranged on the clamping base, a plurality of clamping parts are arranged on the clamping base, and a gear clamping frame is rotatably arranged on the rotating mounting seat; the free end of the gear clamping frame can move to different clamping parts and be clamped with the clamping parts when the rotary mounting seat rotates relative to the clamping base, and when the included angle between the gear clamping frame and the rotary mounting seat changes and is larger than a preset angle, the free end of the gear clamping frame can span to any adjacent clamping part; a locking piece is slidably arranged on the rotary mounting base, when the locking piece slides to a preset position, one end of the locking piece can abut against the free end of the gear clamping frame, and the end, abutting against the gear clamping frame, of the locking piece is slidably connected with the rotary mounting base so as to limit the change of the included angle between the gear clamping frame and the rotary mounting base; therefore, the free end of the gear clamping frame is limited to span the clamping part.

    本发明公开了一种调档装置及船用推进器,涉及船用机械技术领域,包括夹持基座,夹持基座上可转动设置有转动安装座,夹持基座上设置有若干卡位部,转动安装座上可转动设置有档位卡架,档位卡架自由端能够在转动安装座相对于夹持基座转动时,运动至不同卡位部并与该卡位部卡合,在档位卡架与转动安装座之间夹角发生变化且大于预定角度时,档位卡架自由端能够跨越至任一相邻的卡位部;转动安装座上可滑移设置有锁定件,锁定件滑移至预定位置时,锁定件一端可抵顶档位卡架的自由端,且锁定件抵顶档位卡架那一端与转动安装座滑动连接,以限制档位卡架与转动安装座之间夹角发生变化,从而限制档位卡架自由端跨越卡位部。
