Description

TECHNICAL FIELD

[0001] The present application belongs to the field of tools, and particularly relates to a tool rod end protection. BACKGROUND

[0002] With the development of society and the improvement of people's living quality, various tool rods for cleaning, pruning and other daily maintenance are widely used. The tool rod is usually used for pool skimmer, branch pruner, etc., and can realize multifunctionalization by adding different tool heads. However, in the use process of the tool rod, the tail end is easy to contact with the ground or hard objects, which can cause the end to be abraded, deformed, even lose the original function, and the exposed tail end can also scratch the user. Therefore, adding a protection to the tail end of the tool rod to prolong the service life of the rod body and improve the use experience has become a common design idea.

[0003] In addition, when using the tool rod, the user often encounters some difficult-to-handle garbage or sundries (such as floating objects, light objects hanging on branches, etc.). If the tool rod can integrate a simple hooking function, it will effectively improve its use value. However, most of the tool rods on the market currently only provide a single function, and cannot simultaneously meet the protection, hanging and hooking requirements. SUMMARY

[0004] The present application solves the technical problem of the prior art, and provides a tool rod end protection with a hooking tool, which is convenient to disassemble and assemble.

[0005] The technical scheme adopted by the present application to solve the above technical problem is: a tool rod end protection, comprising a plug body inserted into the tail end of a hollow rod body, both ends of the plug body can be inserted into the rod body, one end of the plug body is provided with a hanging part capable of being hung on a wall, and the other end is provided with a hook, and a locking structure is arranged between the plug body and the rod body. The plug body is inserted into the rod body in a right position, so that the hook is hidden in the rod body, which is called a first use state; after the plug body is inserted into the rod body in an upside-down position, the hook is exposed, which is called a second use state, and can be used to hook objects and garbage.

[0006] In the preferred scheme, the locking structure comprises a first hole on the rod body and a protrusion on the plug body, the plug body is further provided with an elastic member for pushing the protrusion into the first hole, and the plug body is provided with a receiving cavity for accommodating the elastic member. Pressing the protrusion can make the protrusion disengage from the first hole, thereby releasing the plug body and making the plug body disengage from the rod body.

[0007] In the preferred scheme, the first hole is a pair of holes, the shape of the elastic member is V-shaped, the plug body has two plug bodies, which are respectively located at the free ends of the V-shaped elastic members, and the plug body is provided with a second hole for the movement of the protrusion.

[0008] In the preferred scheme, the V-shaped tip of the elastic member is away from the hanging part, which facilitates installation.

[0009] In a preferred embodiment, the plug includes a mounting groove on its outer periphery, with a mounting hole at one end of the mounting groove near the suspension portion. The hook includes a first segment embedded in the mounting hole, a second segment located in the mounting groove, and a hook portion away from the plug. The second segment faces the inner wall of the rod. On one hand, in the second usage state, when the hook encounters resistance from an external object, it transmits the force to the inner wall of the rod, which provides a reaction force. This design strengthens the hook. On the other hand, the mounting groove on the outer periphery of the plug facilitates the installation and replacement of the hook. If the hook is damaged, simply insert the first segment of a hook of the same shape into the mounting hole and then insert the second segment into the mounting groove.

[0010] In a preferred embodiment, the mounting hole is perpendicular to the central axis of the plug. This enhances the hook's ability to withstand forces along the axial direction of the rod.

[0011] In the preferred embodiment, the second segment forms an acute angle with the central axis of the plug, with the angle facing away from the suspension part. That is, the end of the hook is inclined towards the inner wall of the rod. This enhances the tightness of the fit between the plug and the rod in the first state. In the second state, the hook can extend beyond the cross-sectional projection range of the plug, providing a wider field of view for hooking.

[0012] In a preferred embodiment, the rod includes a main rod and a secondary rod for inserting into the plug. The secondary rod is telescopically sleeved within the main rod. The secondary rod has a first annular component that slides along it, while the main rod has a second annular component that is fixedly attached. A threaded fastening structure is provided between the first and second annular components. The secondary rod is fitted with a sleeve, which has a contraction joint extending through both ends. One end near the plug has an outward-facing first ramp, and the other end has an outward-facing second ramp. The first annular component has a third ramp pressing against the first ramp, and the second annular component has a fourth ramp pressing against the second ramp. When the secondary rod extends or retracts to a certain position on the main rod, the first and second annular components are tightened. At this point, the third ramp presses against the first ramp, and the fourth ramp presses against the second ramp, ultimately pressing the sleeve onto the secondary rod, thereby fixing the relative positions of the main rod and the secondary rod. This telescopic fixing structure allows for adjustment of the rod's length, facilitating the effective hooking of objects and debris in a second usage state. The rod is telescopic and, combined with a threaded fastening structure, can be adjusted in length according to actual needs, making it more flexible, especially when hooking up garbage.

[0013] In another design, the locking structure includes a limiting protrusion and an external threaded section on the outer periphery of the plug, and an internal threaded section on the inner wall of the rod. The external threaded section is located on one side of the hook, and the diameter of the limiting protrusion is larger than the inner diameter of the rod. The suspension part is interference-fitted with the inner wall of the rod. In the first state, the external threaded section fits onto the internal threaded section. In the second state, the suspension part is inserted into the rod, and the limiting protrusion restricts the plug from further sifting into the rod. The threaded section and limiting protrusion design ensure a secure fit between the plug and the rod in all states, guaranteeing safe and reliable use.

[0014] In summary, this invention adds a plug to the tail end of a traditional pole. This plug has a two-end structure: one end for suspension and the other end has a hook for hooking objects or trash. Compared with existing technologies, this invention integrates suspension, protection, and hooking functions. Different usage states can be achieved by inserting the pole upright or upside down, significantly improving the practical value of the tool pole. The elastic locking structure allows for simple and quick assembly and disassembly without additional tools, making it more convenient to use. The hook's design fits tightly against the inner wall of the pole, effectively distributing force, enhancing the hook's load-bearing capacity, and preventing damage due to excessive force during use. The hook adopts a modular design, allowing for quick replacement via mounting slots and holes, reducing maintenance costs and extending the tool pole's lifespan. This invention has a reasonable structural design and is suitable for pool cleaning, tree trimming, and other scenarios, with broad market application prospects. Attached Figure Description

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] The reference numerals in the attached drawings are as follows: rod body 1, main rod 11, auxiliary rod 12, internal thread section 13, first hole 121, plug body 2, second hole 21, mounting groove 22, mounting hole 23, external thread section 24, limiting protrusion 25, receiving cavity 26, suspension part 3, elastic element 4, protrusion 5, hook 6, first section body 61, second section body 62, hook part 63, first ring-shaped element 7, third ramp 71, second ring-shaped element 8, fourth ramp 81, rod sleeve 9, first ramp 91, second ramp 92, threaded fastening structure 93, contraction joint 94.

[0028] Example 1, as Figures 1 to 9 As shown. The tool handle end protector includes a plug 2 inserted into the tail end of a hollow handle 1. Both ends of the plug 2 can be inserted into the handle 1. One end of the plug 2 has a hanging part 3 for hanging on a wall, and the other end has a hook 6. A locking structure is provided between the plug 2 and the handle 1. Figure 1 As shown, the plug 2 is inserted upright into the rod 1, so that the hook 6 is hidden inside the rod 1, which is called the first use state; as Figure 3 As shown, after inserting the plug 2 upside down into the rod 1, the hook 6 is exposed, which is called the second use state, and can be used to hook objects and garbage.

[0029] In the embodiments, such as Figure 2 As shown, the locking structure includes a first hole 121 on the rod 1 and a protrusion 5 on the plug 2, as... Figure 4 and Figure 5 As shown, the plug body 2 is also provided with an elastic element 4 for pushing the protrusion 5 into the first hole 121, and the plug body 2 is provided with a receiving cavity 26 for accommodating the elastic element 4. Pressing the protrusion 5 can disengage the protrusion 5 from the first hole 121, thereby releasing the plug body 2 and causing the plug body 2 to disengage from the rod body 1.

[0030] In the embodiments, such as Figure 5 As shown, the first hole 121 is a pair, the elastic element 4 is V-shaped, and there are two plugs 2, located at the free ends of the V-shape of the elastic element 4, as shown. Figure 7 As shown, the plug body 2 is provided with a second hole 21 for the protrusion 5 to move.

[0031] In the embodiments, such as Figure 7 As shown, the V-shaped tip of the elastic element 4 is away from the suspension part 3, which facilitates installation.

[0032] In the embodiments, such as Figure 6 , 7As shown, the plug 2 includes a mounting groove 22 on its outer periphery. A mounting hole 23 is provided at one end of the mounting groove 22 near the suspension part 3. The hook 6 includes a first segment 61 embedded in the mounting hole 23, a second segment 62 located in the mounting groove 22, and a hook part 63 away from the plug 2. The second segment 62 faces the inner wall of the rod 1. On one hand, in the second usage state, when the hook 6 encounters resistance from an external object, it transmits the force to the inner wall of the rod 1, where the inner wall provides a reaction force. This design strengthens the hook 6. On the other hand, the mounting groove 22 on the outer periphery of the plug 2 facilitates the installation and replacement of the hook 6. After the hook 6 is damaged, simply insert the first segment 61 of the hook 6 of the same shape into the mounting hole 23 and then insert the second segment 62 into the mounting groove 22.

[0033] In this embodiment, the mounting hole 23 is perpendicular to the central axis of the plug body 2. This enhances the ability of the hook 6 to withstand forces along the axial direction of the rod body 1.

[0034] In this embodiment, the second segment 62 forms an acute angle with the central axis of the plug 2, with the angle facing away from the suspension part 3. That is, the end of the hook 6 is inclined towards the inner wall of the rod 1. This can enhance the tightness of the fit between the plug 2 and the rod 1 in the first state. In the second state, the hook part 63 can extend beyond the cross-sectional projection range of the plug 2, providing a wider field of view for hooking.

[0035] In the embodiments, such as Figures 1 to 5 as well as Figure 8 As shown, the rod body 1 includes a main rod 11 and a secondary rod 12 for inserting the plug body 2. The secondary rod 12 is telescopically sleeved inside the main rod 11. The secondary rod 12 is slidably provided with a first annular member 7, and the main rod 11 is fixedly provided with a second annular member 8. A threaded fastening structure 93 is provided between the first annular member 7 and the second annular member 8. The secondary rod 12 is fitted with a rod sleeve 9, as shown... Figure 9 As shown, the sleeve 9 has a contraction joint 94 extending through both ends of itself, as... Figure 8 and Figure 9 As shown, one end near the plug 2 is provided with an outward-facing first ramp 91, and the other end is provided with an outward-facing second ramp 92; the first annular member 7 is provided with a third ramp 71 pressing on the first ramp 91, and the second annular member 8 is provided with a fourth ramp 81 pressing on the second ramp 92. When the auxiliary rod 12 extends or retracts to a certain position on the main rod 11, the first annular member 7 and the second annular member 8 are tightened. At this time, the third ramp 71 presses against the first ramp 91, and the fourth ramp 81 presses against the second ramp 92, finally pressing the rod sleeve 9 onto the auxiliary rod 12, thereby fixing the relative position of the main rod 11 and the auxiliary rod 12. This telescopic fixing structure can adjust the length of the rod 1, thereby facilitating the effective hooking of objects and garbage by the hook 6 in the second use state. The rod 1 has a telescopic function, and combined with the threaded fastening structure 93, the length can be adjusted according to actual needs, which is especially flexible when hooking garbage.

[0036] Example 2 is similar to Example 1, except that the connection structure between the plug 2 and the rod 1 is as follows: Figure 10 and Figure 11 As shown, the locking structure includes a limiting protrusion 25 and an external threaded section 24 located on the outer periphery of the plug body 2, and an internal threaded section 13 located on the inner wall of the rod body 1. The external threaded section 24 is located on one side of the hook 6. The diameter of the limiting protrusion 25 is larger than the inner diameter of the rod body 1. The suspension part 3 is interference-fitted with the inner wall of the rod body 1. In the first state, the external threaded section 24 is fitted onto the internal threaded section 13. In the second state, the suspension part 3 is inserted into the rod body 1, and the limiting protrusion 25 restricts the plug body 2 from further sifting into the rod body 1. Through the design of the threaded section 24 and the limiting protrusion 25, it is ensured that the plug body 2 can be firmly fitted with the rod body 1 in different states, making it safe and reliable to use.

[0037] The preferred embodiments of the present invention have been described, and various changes or modifications made by those skilled in the art will not depart from the scope of the present invention.
