The secondary tail rod has a tapered shape, with its diameter gradually increasing from the head end A to the tail end B, and a limiting member is provided on the secondary tail rod. The tail rod has a socket and a receiving cavity. The tail end B of the secondary tail rod is axially slidably inserted into the socket at the front end of the tail rod. The diameter of the tail end B of the secondary tail rod is larger than the diameter of the socket of the tail rod. When the tail rod and the secondary tail rod are extended to their maximum positions, the socket of the tail rod and the tail end B of the secondary tail rod are tightly connected. When the tail rod and the secondary tail rod are retracted, the socket of the tail rod falls into the limiting member, and the socket of the tail rod and the limiting member are tightly connected. Compared with the prior art, the advantage of this utility model is that it can be improved on all existing fishing rods. Only a limiting member needs to be set at the front end or middle of the secondary tail rod to achieve length adjustment, without the need for complex internal mechanisms, resulting in extremely low cost.

Description

Technical Field

[0001] This utility model relates to the field of fishing rod technology, and in particular to a handle extension structure and a fishing rod. Background Technology

[0002] A fishing rod, also known as a fishing rod, is a fishing tool. It is a long, thin, multi-section rod-shaped object, usually with a handle that tapers to a point towards the end. It is used with a fishing line connected to a baited hook. When fishing with a fishing rod, you need to hold the handle. To prevent the rod from slipping in wet environments, the handle is usually treated with a non-slip surface.

[0003] Existing fishing rods consist of multiple tapered extension rods. When the fishing rod is extended, each extension rod can be tightened and fixed, but when it is retracted, adjacent extension rods cannot be tightened. Therefore, the fishing rod can only be extended to its maximum length and cannot be adjusted.

[0004] For example, the Chinese utility model patent "Adjustable Fishing Rod" with patent publication number CN219844663U uses a positioning mechanism to adjust the length of the handle and the rod body. Its disadvantages are: although the length can be adjusted, the positioning mechanism consists of complex internal components, requiring processing of the inner wall of the handle, resulting in high manufacturing costs and difficulty in repairing damage. Utility Model Content

[0005] This utility model addresses the problem that fishing rods use a positioning mechanism to adjust the length of the grip and the rod body. However, the positioning mechanism has complex internal components and requires processing of the inner wall of the grip, resulting in high manufacturing costs and difficulty in repairing damage. The technical problem this utility model aims to solve is to provide a fishing rod with a simple structure that can adjust the length in two positions.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a handle extension structure for a fishing rod, including a tail rod as a gripping part, and a secondary tail rod sleeved on the tail rod.

[0007] The secondary tail rod has a taper, and its diameter gradually increases from the head end A to the tail end B. The secondary tail rod is also equipped with a limiting component.

[0008] The tail rod has a socket and a receiving cavity, and the tail end B of the secondary tail rod is axially slidably inserted from the socket at the front end of the tail rod;

[0009] The diameter of the tail end B of the secondary tail rod is larger than the diameter of the tail rod's inlet. When the tail rod and the secondary tail rod are stretched to their maximum positions, the inlet of the tail rod and the tail end B of the secondary tail rod are tightly connected. When the tail rod and the secondary tail rod are retracted, the inlet of the tail rod falls into the limiting member, and the inlet of the tail rod and the limiting member are tightly connected.

[0010] The limiting component described in Scheme 1 is a limiting ring, which is glued to the secondary tail rod. The limiting ring has a taper along its axial direction, with the end with the smallest diameter facing the insertion direction of the tail rod.

[0011] The limiting component described in Scheme 2 is a limiting ring, which is glued to the secondary tail rod. The limiting ring is made of silicone or rubber, and the limiting ring can be elastically compressed when the tail rod is inserted.

[0012] The limiting component described in Scheme 3 is a limiting ring. An annular groove is provided on the secondary tail rod. The limiting ring is fitted inside the annular groove, and the limiting ring and the annular groove are interference-fitted. The outer edge of the limiting ring protrudes from the outer surface of the secondary tail rod.

[0013] Scheme 4 describes a limiting component as a limiting sleeve. The limiting sleeve has a connecting sleeve that extends into the tailstock insertion port. The connecting sleeve is fixed to the outer wall of the front or middle position of the secondary tailstock. The end of the limiting sleeve away from the connecting sleeve has a flange, and the connecting sleeve has a tapered shape. (The flange is for identifying the direction during installation.)

[0014] The fishing rod includes the handle extension structure of the fishing rod described above, and the secondary tail rod is hollow inside, with multiple sections of axially sliding extension rods fitted inside the secondary tail rod.

[0015] Compared with existing technologies, this invention has the following advantages: it can be improved on all existing fishing rods by simply setting a limiting component at the front or middle of the secondary tail rod. When the tail rod retracts, the insertion port of the tail rod engages with the limiting component of the secondary tail rod to achieve expansion and tightening, thus shortening the fishing rod by one section and achieving an adjustment function. The implementation cost of this invention is extremely low. The limiting component is a limiting ring. When the tail rod and secondary tail rod are extended to the long rod state, it retains the original structure of the fishing rod. When the tail rod and secondary tail rod are retracted to the short rod state, the insertion port of the tail rod engages with the limiting ring to secure it. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example 1

[0025] This embodiment mainly describes the handle extension structure of the fishing rod, as detailed below:

[0026] like Figures 1 to 5 As shown, the handle extension structure of the fishing rod, which serves as the gripping part of the entire rod, mainly consists of the tail rod 1 and the secondary tail rod 2, which is fitted inside the tail rod 1. The tail rod 1 is the part that the operator directly grips, and the front end of the tail rod 1 has a socket 4 with an internal receiving cavity 3. The outer surface of the tail rod 1 can be further coated with EVA (ethylene-vinyl acetate copolymer) or cork anti-slip layer to improve grip stability in wet conditions. The secondary tail rod 2 has a tapered shape with a gradually increasing diameter from the head end A to the tail end B, and a limiting member 5 is provided on the secondary tail rod 2. The tail end B of the secondary tail rod 2 is axially slidably inserted into the receiving cavity 3 from the insertion port 4 at the front end of the tail rod 1. The diameter of the tail end B of the secondary tail rod 2 is larger than the diameter of the insertion port 4 of the tail rod 1. When the handle needs to be extended, the tail end B of the secondary tail rod 2 is axially pulled out from the insertion port 4 of the tail rod 1. When the tail rod 1 and the secondary tail rod 2 are stretched to their maximum positions, the insertion port 4 of the tail rod 1 and the tail end B of the secondary tail rod 2 form a radial expansion, achieving a reliable and wobbly fastening connection. When the handle needs to be shortened, the tail rod 1 is pushed in the opposite direction, causing the insertion port 4 to slide along the secondary tail rod 2 to the area where the limiting member 5 is located. The outer edge of the limiting member 5 is close to the insertion port 4 of the tail rod 1, and the insertion port 4 of the tail rod 1 and the limiting member 5 form a radial expansion, thereby locking the relative position of the tail rod 1 and the secondary tail rod 2 in the shortened state.

[0027] By using the simple combination of the tail rod 1, the secondary tail rod 2 and the limiting component 5, the handle length can be freely switched between the "longest and one section shorter" settings without adding a complex internal mechanism. This overcomes the defect of existing technology that can only extend but not retract. Moreover, this utility model does not require a complex internal mechanism, has extremely low cost, and can be directly modified on existing fishing rods.

[0028] Specifically, the limiting component 5 is a limiting ring, which is fixed to the outer wall of the secondary tail rod 2 by adhesive. The axial direction of this limiting ring is also designed to be tapered, that is, the smallest diameter end faces the insertion port 4 of the tail rod 1. The tapered limiting ring plays a guiding role when the tail rod 1 retracts. The insertion port 4 first contacts the smaller end of the limiting ring, and then gradually expands and deforms along the tapered surface to achieve progressive tightening, which reduces instantaneous resistance and improves locking reliability. At the same time, the adhesive bonding method eliminates the need to process complex structures on the secondary tail rod 2, further reducing manufacturing costs. Example 2

[0029] The only difference between this embodiment and Embodiment 1 is that it provides a different structure for the limiting member 5. Specifically, the limiting member 5 is a limiting ring, which is glued to the outer wall of the secondary tail rod 2. The limiting ring is made of elastic materials such as silicone or rubber. When the insertion port 4 of the tail rod 1 is fitted into the limiting ring, the limiting ring can be elastically compressed, allowing the user to complete the extension and retraction operation with one hand; the elastic rebound also ensures sufficient tension force to prevent loosening. Silicone or rubber also has corrosion-resistant and anti-aging properties, allowing it to adapt to humid outdoor environments for a long time. Example 3

[0030] The only difference between this embodiment and Embodiment 1 is that it provides a different structure for the limiting member 5. Specifically, the limiting member 5 is a limiting ring, and an annular groove is formed on the outer wall of the secondary tail rod 2. The limiting ring is pressed into the annular groove and subjected to an interference fit. The limiting ring is installed after the annular groove, and its outer edge protrudes from the outer surface of the secondary tail rod 2. The combination of the interference fit and the annular groove prevents the limiting ring from moving axially and avoids the risk of adhesive failure. The protruding outer edge of the limiting ring can create radial tension between the limiting ring and the insertion port 4, thereby ensuring that the relative positions of the tail rod 1 and the secondary tail rod 2 are locked in the shortened state. The height of the protruding part of the limiting ring can be precisely controlled, thereby ensuring the consistency of the tension force and improving the assembly accuracy during mass production. Example 4

[0031] The only difference between this embodiment and Embodiment 1 is that it provides a different structure for the limiting member 5, specifically: the limiting member 5 is an integral limiting sleeve. The limiting sleeve is fitted onto the outer wall of the secondary tail rod 2, and the limiting sleeve has a connecting sleeve that extends into the insertion port 4 of the tail rod 1. The connecting sleeve is fixed to the front end or middle outer wall of the secondary tail rod 2 by adhesive or thread. The connecting sleeve has a taper, that is, the smallest diameter end faces the insertion port 4 of the tail rod 1. The outer wall of the limiting sleeve at the end away from the connecting sleeve has a flange arranged circumferentially. When the tail rod 1 retracts, the inner wall of the insertion port 4 first contacts the tapered surface of the connecting sleeve and gradually expands until it abuts against the flange to achieve axial positioning. The flange prevents excessive retraction. Example 5

[0032] This embodiment mainly describes the fishing rod, specifically as follows: The fishing rod as a whole includes the aforementioned handle extension structure. The secondary tail rod 2 has a hollow internal structure, and multiple sections of axially sliding extension rod 6 are fitted inside the secondary tail rod 2. In use, the extension rod 6 is first pulled out section by section to form a complete rod body; then, depending on the fishing spot space, the tail rod 1 and secondary tail rod 2 are stretched to their maximum length or shortened by one section through the handle extension structure, achieving secondary adjustment of the overall rod length. This fishing rod retains the advantages of the existing "multi-stage tapered rod tensioning" structure in terms of simplicity and low cost, while adding a handle telescopic function to meet the needs of different scenarios such as shore fishing, boat fishing, and narrow spaces; at the same time, all improvements can be directly implemented on existing fishing rods without the need for new molds, and have significant market promotion value.

[0033] As can be seen from the above specific embodiments, this utility model successfully solves the problems of existing fishing rods being unable to lock after retraction and having no adjustable length, with very few parts, minimal processing, and the simplest assembly process, and also has the significant advantages of reliability, low cost, and easy maintenance.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] The above provides a detailed description of the handle extension structure and the fishing rod provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
