The limiting stop 18 provided in the inner rear plug 3 can, after threaded installation, use the limiting stop 18 to block the fishing rod body 1, preventing the fishing rod body 1 from colliding with the reverse osmosis membrane 16. And the diversion inclined plate 21 provided inside it can play a role in diverting moisture, enabling the moisture to flow out better, playing a better drainage role, and effectively ensuring the drainage effect.

[0030] As Figures 1 - 7 shown, as a preferred embodiment; a circular snap ring 11 is fixedly connected to the outer surface of the outer rear plug 6. A circular card slot 12 is formed on the outer surface of the external thread cylinder 9. A protective circular sleeve 10 is sleeved on the outer surface of the outer rear plug 6. An anti-slip sleeve 2 is sleeved on the outer surface of the fishing rod body 1. Further, by providing the circular snap ring 11, when the outer rear plug 6 is threadedly installed with the external thread cylinder 9, the circular snap ring 11 on the outer rear plug 6 will snap into the circular card slot 12 to better install it, ensuring the stability of the installation, enhancing the connection strength of the rear plug, and preventing the rear plug from falling off during use. And the provided protective circular sleeve 10 can better operate it when installing the outer rear plug 6, having the advantage of more convenient installation operation. And by providing the anti-slip sleeve 2, it can play a good anti-slip role during use.

[0031] As Figures 1 - 7 shown, as a preferred embodiment; a connecting round rod 13 is fixedly connected to the outer surface of the outer rear plug 6. A circular lifting ring 4 is fixedly connected to the outer surface of the connecting round rod 13. A counterweight round block 20 is fixedly connected to the inner wall of the outer rear plug 6.

This design not only makes the rod body stable but also makes the center of gravity move backward, thereby enhancing the overall use experience and effect, can improve the weight distribution of the fishing rod, make it more in line with the use habits of fishermen, improve the comfort of fishing, improve the use performance of the fishing rod, and ensure the optimization of the fishing experience.

[0032] The working process of the present utility model is as follows:

[0033] When the fishing rod with a drainage and sand - prevention rear plug is used later, first, one end of the inner rear plug 3 can be sleeved on the fishing rod body 1. By using the threaded connection relationship between the main internal thread 14 and the connecting external thread 7, the inner rear plug 3 can be threadedly installed on the fishing rod body 1. Then, the outer rear plug 6 is sleeved on the external thread cylinder 9. By using the cooperation between the secondary internal thread 19 and the external thread cylinder 9, the outer rear plug 6 can be threadedly installed on the external thread cylinder 9. At the same time, the circular snap ring 11 on the outer rear plug 6 will be inserted into the circular slot 12, and the counterweight circular block 20 inside the outer rear plug 6 can adjust the balance of the rod body by increasing the weight, moving the center of gravity of the large handle backward, so as to achieve the balance of the rod body. When in use, the filter sheet 15 and the reverse osmosis membrane 16 inside the inner rear plug 3 can be used for filtering and adsorbing sand to prevent sand from entering the fishing rod body 1 and avoid abrasion and damage to the fishing rod body 1. And its moisture can pass through the filter sheet 15, the reverse osmosis membrane 16, and the drainage arc opening 5 and be discharged to the outside to help discharge the moisture entering during use in water, preventing water accumulation from causing rod body corrosion or weight increase. When it is necessary to clean the sand adsorbed on the surfaces of the filter sheet 15 and the reverse osmosis membrane 16, the outer rear plug 6 can be rotated and removed from the external thread cylinder 9, the inner rear plug 3 can be removed from the fishing rod body 1, and then the inner rear plug 3 and the external thread cylinder 9 are placed upside down to discharge the filtered sand from the external thread cylinder 9 to complete the cleaning step. This is the working process and working principle of the device.

[0034] Finally: The above - mentioned are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
