Abstract

The invention relates to a rowing paddle, in particular to a rowing paddle conveniently adjusting and controlling the boat speed. The rowing paddle comprises a fixing seat, a gearbox component, a control handle component, a rotary seat component, a rowing paddle component, a push-pull seat component and a hinging board. The gearbox component is fixedly connected to the right side of the top end ofthe fixing seat; the rotary seat component is connected to the left side of the top end of the fixing seat in a running fit mode; the lower end of the control handle component is connected to the inside of the gearbox component in a sliding fit mode; and the left end of the control handle component is fixedly connected with the right end of the push-pull seat component, the push-pull seat component is connected to the upper end of the rotary seat component in a sliding fit mode, and the left end of the push-pull seat component is hinged to the middle end of the rowing paddle component. The rowing paddle conveniently adjusting the boat speed can be conveniently controlled by a green hand, the gearbox component is arranged in the rowing paddle conveniently adjusting the boat speed, and a rowing person can adjust the rowing pushing distance of the rowing paddle component according to the actual requirement.

Description

technical field [0001] The invention relates to a rowing oar, in particular to a rowing oar which is convenient for regulating the speed of a boat. Background technique [0002] Oars are one of the most important tools when rowing a boat. At present, the oars are mainly composed of three parts: the oar handle, the oar shaft and the oar blade. The number of oars is used to compensate for the amount of strokes, so it is generally easy to consume people's physical strength when using oars. And well-known, when paddle and boat are perpendicular, the action force of water to paddle blade is maximum, just when paddle and boat are perpendicular, water is the biggest to the propelling force of boat, and the speed of boat is the fastest. Therefore, how to adjust the angle between the paddle and the boat, keep the water’s thrust on the paddle changed, and how to control the speed of the boat through paddles are very important for rowing. However, the structure of paddles on the mark...
