[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an easy-to-maintain paddle, including a grip bar and multiple paddle plates 3. The grip bar includes a central tube 1 and multiple side bars 2. The inner diameter of the openings at both ends of the central tube 1 is reduced inward to form a connecting hole 10. The side bars 2 are respectively vertically arranged at both ends of the central tube 1. One end of each side bar 2 is provided with a connecting groove. A rotating seat 6 is movably installed in the connecting groove through a pin. The other end of each rotating seat 6 extends through the connecting hole 10 into the central tube 1 and is equipped with a column 8. The other end of each column 8 is expanded outward to form a limiting part 9. The other end of each side bar 2 is fixedly connected to the paddle plate 3.

[0022] In this embodiment, a limit ring 4 is installed on each side rod 2 near the connecting groove. A first screw hole is provided vertically on each limit ring 4. A second screw hole is provided at both ends of the center tube 1, which are directly opposite the first screw hole. A screw rod 7 is threaded into each of the corresponding first and second screw holes. A rotating handle 5 is installed at one end of each screw rod 7.

[0023] In this embodiment, the side rod 2 is provided with external threads near the limiting ring 4, and the connecting holes 10 at both ends of the central tube 1 are provided with internal threads.

[0024] In this embodiment, the diameter of the column 8 is matched with the inner diameter of the connecting hole 10, the diameter of the limiting part 9 is matched with the inner diameter of the central tube 1, and the opposite end face of the limiting part 9 is abutted against the end face of the connecting hole 10. After the side rod moves outward, the limiting part can abut against the end face of the connecting hole, thereby limiting the outward movement distance and preventing the side rod from detaching from the central tube.

[0025] In this embodiment, the diameter of the side rod 2 matches the inner diameter of the connecting hole 10, so that the side rod can be smoothly inserted into the connecting hole and threadedly connected to the connecting hole.

[0026] In this embodiment, the central tube 1 is made of stainless steel, which increases its strength, prevents breakage, and avoids rusting.

[0027] When in use, rotate the handle to turn the screw, so that the screw is unscrewed from the first screw hole until the end face of the screw is flush with the side of the limiting ring. At this time, the side rod can be lifted upward around the pin. After the side rod is aligned with the center tube, push the side rod inward and rotate the side rod so that the side rod can enter the connecting hole and be threaded into the connecting hole until the limiting ring abuts against the end face of the center tube, so that the grip rod is spliced ​​into one piece for paddling operation.

[0028] When maintenance is required, such as Figure 1 As shown, rotating the side rod outward causes the rotating seat and column to move until the limiting part abuts against the end face of the connecting hole. At this point, the side rod is located on the outside. After the side rod is folded down, the outer ring surface of the side rod can abut against the end face of the central tube. Then, rotating the handle allows the screw to be threaded into the first screw hole. The screw can position the side rod, making the side rod and the central tube form a U-shaped structure. This allows the device to be directly mounted on the shoulder, enabling the device to be quickly moved to the maintenance area for inspection and maintenance.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
