[0002] A paddle is a rowing tool. The upper end is a round rod, which is convenient for holding by hand and is called a grip. The lower end is in the shape of a plate, called a paddle board, which is used to paddle water. It utilizes Newton's third law of physics to move the boat forward through the reaction force of water waves. Currently, many boat sports teams need to use a lot of paddles for team training. Most teams will pile the paddles in a corner, or use sacks to pack them directly, or line them up against the wall. If the paddles are not dried after use, they will easily become moldy and deteriorate when piled together, and they will often take up a lot of space if they are lined up in a row.

[0003] After searching, the patent number is CN213323633U, which discloses an adjustable height and rotatable oar rack, in which the oars are vertically hung on the rack. Hanging the oars in the air can help the moisture on the oars to drip off and facilitate ventilation and drying, effectively avoiding the mold and deterioration of the oars; the oars can be hung on the rack in sequence along the length direction of the rack, effectively saving storage space, but when in use, when adjusting the position of the hanging rack, due to the high height of the top of the vertical pole, it is difficult for the user to adjust the fixed hanging rack, affecting the adjustment efficiency, and when in use, the oars hung on the rack are not fixed, and are easy to fall off during a collision, affecting the safety of the oars.

[0004] For this reason, a height-adjustable and rotatable oar rack is proposed. Utility Model Content
