Description

Technical Field

[0001] The invention relates to the technical field of kayaks, and in particular to a kayak getting on and off fixing device. Background Art

[0002] Canoeing is divided into two events: kayaking and rowing. Kayaking is propelled by a double-bladed paddle, and rowing is propelled by a single-bladed paddle. Canoeing can be divided into still water events and whitewater events. Competitions held on natural or artificial lakes are called still water events. The transverse and longitudinal lines of the hulls of kayaks and rowing boats should be raised (only in the horizontal and vertical directions); any horizontal point on the deck shall not be higher than the highest point of the front edge of the first cockpit; no external attachments may be added to the boat to avoid causing unfairness to the athletes; during the competition, various electronic or electric equipment may not be placed on the boat, including: water pumps, speedometers, fatigue meters, heart rate monitors, and kayak paddles are sports equipment. The kayak paddle is a tool for kayakers to row forward. The kayak paddle is a double-bladed paddle with blades on both ends of the paddle shaft. Its main structural feature is that the directions of the two blades are vertical or nearly vertical. According to the different directions of the deflection of the blades, there are left-turn paddles and right-turn paddles. Athletes can choose left or right paddles according to their paddle holding habits. Because the rules do not have very strict and unified regulations on the size and shape of the blades, the development and changes of kayak paddles have been extremely rapid in recent decades. The weight, length, shape, blade and blade area of ​​various paddles can be selected according to the height, technical style, strength, gender and different types of boats.

[0003] At present, when the lake is small, people can get on the boat and place the oar flat at 90 degrees behind the deck near the edge of the cabin, and hold the oar and the cabin edge with the same hand to fix the hull, and then move back and forth between the boat and the ground. Sometimes the user cannot quickly find a suitable support point to move, which makes it very troublesome for the user to get on and off the boat. In addition, it is not easy to insert and maintain the balance of the support due to the soft bottom of the lake, which may cause the support to slide with the lake. Summary of the invention
