Description

Technical Field

[0001] The present invention relates to the field of bags, and more particularly to telescopic rod components and backpacks with telescopic rods.

Background Art

[0002] In existing backpacks with telescopic rods, a shoulder strap, a telescopic rod assembly, and a caster system are integrally provided. When the load is light, it is carried with the shoulder strap, and when the load is heavy, it is dragged with the telescopic rod assembly and the casters. However, when dragging, the shoulder strap that is not stored hangs down, so the lower part of the shoulder strap continuously contacts the ground, making it easy for friction and dirt to occur. In addition, there is also a risk of movement interference that when the caster rolls, the shoulder strap may be caught in the gap, which is likely to cause interference during dragging and abnormal wear of the components. This seriously affects the dragging of the backpack with a telescopic rod, significantly reducing the operational convenience and the reliability of the device.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In view of the above technical problems, an object of the present invention is to provide a telescopic rod component and a backpack with a telescopic rod. The latching hole in the telescopic rod component connects the shoulder strap. When the telescopic rod assembly is pulled up, the latching part simultaneously pulls up the shoulder strap through the latching hole, suspends it in the air, and keeps it away from the ground. Thereby, it is possible to avoid the continuous contact of the shoulder strap with the ground and the entanglement of the shoulder strap in the gap when the caster rolls, improving the safety and convenience during the dragging of the backpack with a telescopic rod.

Means for Solving the Problems

[0004] To achieve the above objective, the present invention provides a telescopic rod component that is attached to a telescopic rod assembly. The telescopic rod assembly comprises a plurality of telescopic rods, and the telescopic rod component comprises a support portion and a latching portion.

[0005] The support portion is fixedly attached to the top of the telescopic rod of the telescopic rod assembly.

[0006] The fastening portion is provided on one side of the support portion and is located relative to the outside of the telescopic rod assembly. The fastening portion is provided with a fastening hole for connecting a shoulder strap.

[0007] When the telescopic rod assembly is pulled up, the latching part passes through the latching hole and simultaneously pulls up the shoulder strap, leaving it suspended in mid-air.

[0008] In some embodiments, the latching portion is provided with a latching hole that penetrates it vertically, and the latching portion comprises a first hole-forming portion, a second hole-forming portion, and a third hole-forming portion, the first hole-forming portion and the third hole-forming portion being provided axially symmetrically on both sides of the support portion, and the second hole-forming portion connecting the ends of the first hole-forming portion and the third hole-forming portion that are away from the support portion.

[0009] In some embodiments, the first hole-forming portion and the third hole-forming portion extend diagonally in opposite directions such that the first hole-forming portion, the second hole-forming portion, and the third hole-forming portion form a trapezoidal shape.

[0010] In some embodiments, the support portion comprises a first rod and a second rod, the first rod being provided in contact with the inside of the telescopic rod, the second rod being provided above the first rod, and the latching portion being connected to the second rod.

[0011] In some embodiments, the support portion is provided with an insertion hole that penetrates it axially, through which another telescopic rod can be inserted, thereby allowing another telescopic rod to be movably attached within the telescopic rod.

[0012] In some embodiments, the bottom of the first rod is further provided with a plurality of elastic grooves, thereby giving the bottom of the first rod some degree of elasticity to fit the inner wall of the telescopic rod.

[0013] In some embodiments, the first rod is further provided with a plurality of locking blocks arranged symmetrically, and the locking blocks are locked and fixed within the locking grooves of the telescopic rod.

[0014] Another aspect of this application further provides a backpack with a telescopic rod, comprising a telescopic rod component, a pack body, a base, and a shoulder strap, as described in any one of the preferred embodiments described above. The pack body is fixedly attached to the base, the base is provided with a telescopic rod assembly and casters, the telescopic rod component is attached to the telescopic rod assembly, the shoulder strap is provided on one side of the pack body, the shoulder strap is provided with a connecting strap, the end of the connecting strap is fixedly connected to a hook hole in the telescopic rod component.

[0015] In some embodiments, the telescopic rod assembly is a single telescopic rod comprising a first telescopic rod, a second telescopic rod, and a third telescopic rod, wherein the first telescopic rod is fixedly attached to the base, the second telescopic rod is slidably attached to the first telescopic rod, the telescopic rod component is fixedly attached to the top of the second telescopic rod, the third telescopic rod is inserted through the insertion hole of the telescopic rod component and is slidably attached to the second telescopic rod, and a pull handle is provided at the top of the third telescopic rod.

[0016] In some embodiments, the connecting strap is fixedly connected at one end to the bottom of the shoulder strap, and the other end passes through the fastening hole and is fixedly connected with adhesive tape on one side of the connecting strap. [Effects of the Invention]

[0017] Compared to conventional technology, the telescopic rod component and the backpack with telescopic rod provided by this invention have at least one of the following beneficial effects.

[0018] 1. The locking holes in the telescopic rod components connect to the shoulder straps. When the telescopic rod assembly is raised, the locking parts pass through the locking holes and simultaneously pull up the shoulder straps, suspending them in mid-air and lifting them off the ground. This prevents the shoulder straps from being in continuous contact with the ground and from getting caught in the gap when the casters roll, improving safety and convenience when dragging the backpack with the telescopic rod.

[0019] 2. Because the first, second, and third hole-forming sections form a trapezoidal shape, a larger connecting area is provided, allowing the shoulder strap to remain stable even under relatively large tensile forces and preventing damage from excessive localized stress.

[0020] 3. The first rod is positioned in contact with the inside of the telescopic rod, thereby ensuring a tight fit and providing a stable support base. The second rod is located above the first rod, and its latching portion is connected to the second rod, thereby forming a continuous structural layout and ensuring overall stability and the strength of the connection.

[0021] 4. In the telescopic rod component, a plurality of elastic grooves are provided at the bottom of the first rod, so that the bottom of the first rod has a certain degree of elasticity. This not only enhances the adhesion between the first rod and the inner wall of the telescopic rod, but also provides higher adaptability, ensuring that stable connection can be maintained in different usage environments. The locking block on the first rod accurately fits into the locking groove on the telescopic rod, thereby ensuring that the telescopic rod component is firmly locked to the telescopic rod. Therefore, it not only provides a reliable fixing effect, but also enables the user to quickly install and remove the telescopic rod component, greatly improving the ease of use.

[0022] 5. The hanging holes provided in the telescopic rod component connect the shoulder strap and form a dynamic cooperation mechanism with the shoulder strap. When the telescopic rod assembly is pulled up, the hanging part and the hanging hole cooperate to cause a controllable vertical displacement of the shoulder strap, keeping it in a floating state from the ground. This effectively eliminates the friction contact surface between the bottom surface of the shoulder strap and the ground and blocks the adhesion path of contaminants. In addition, a dynamic safety distance is formed between the shoulder strap and the caster, avoiding the risk of rolling interference caused by the entanglement of the shoulder strap, and simultaneously improving the smoothness of movement during dragging and the maintenance efficiency of the device.

[0028] In addition, terms such as "first," "second," etc., used in this application's description are used solely to distinguish between descriptions and should not be understood as indicating or implying relative importance. The above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention, and it should be noted that those skilled in the art can make several further improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered to be within the scope of protection of the present invention.

[0029] Referring to Figures 1 to 3, the present invention provides a telescopic rod component 1 that is attached to a telescopic rod assembly 2. The telescopic rod assembly 2 comprises a plurality of telescopic rods, and the telescopic rod component 1 comprises a support portion 11 and a hooking portion 12. The support portion 11 is fixedly attached to the top of the telescopic rod of the telescopic rod assembly 2. The hooking portion 12 is provided on one side of the support portion 11 and is located relative to the outside of the telescopic rod assembly 2. The hooking portion 12 is provided with a hooking hole 120 for connecting a shoulder strap 5. When the telescopic rod assembly 2 is raised, the hooking portion 12 simultaneously raises the shoulder strap 5 through the hooking hole 120, causing it to be suspended in mid-air.

[0030] In this embodiment, the latching hole 120 in the telescopic rod component 1 is configured to connect to the shoulder strap 5. When the telescopic rod assembly 2 is pulled up, the latching part 12 simultaneously pulls up the shoulder strap 5 through the latching hole 120, suspending it in mid-air and lifting it off the ground. This prevents the shoulder strap from being in continuous contact with the ground and from getting caught in the gap when the casters roll, improving safety and convenience when dragging the backpack with the telescopic rod.

[0031] Specifically, the telescopic rod assembly 2 comprises multiple telescopic rods, which extend and retract relative to each other, thereby extending the overall length of the telescopic rod assembly 2. The telescopic rod component 1 is attached to the top of the telescopic rods of the telescopic rod assembly 2, and the telescopic rod component 1 comprises a support portion 11 and a hook portion 12. The support portion 11 is fixedly attached to the top of one of the telescopic rods of the telescopic rod assembly 2, providing stable support. The hook portion 12 is provided on one side of the support portion 11 and is located relative to the outside of the telescopic rod assembly 2. The hook portion 12 is provided with a hook hole 120 for connecting the shoulder strap 5. When the telescopic rod assembly 2 is pulled up, the hook portion 12 simultaneously pulls up the shoulder strap 5 through the hook hole 120, suspending it in mid-air and lifting it off the ground. This prevents the shoulder strap 5 from being in continuous contact with the ground, prevents the shoulder strap 5 from getting dirty or getting caught in the gaps when the casters roll, and significantly improves safety and convenience when the backpack with the telescopic rod is being dragged. In addition, the fastening portion 12 is provided with fastening holes 120 passing through it in a vertical direction, and the fastening portion 12 comprises a first hole forming portion 121, a second hole forming portion 122, and a third hole forming portion 123, the first hole forming portion 121 and the third hole forming portion 123 being provided axially symmetrically on both sides of the support portion 11, and the second hole forming portion 122 connecting the ends of the first hole forming portion 121 and the third hole forming portion 123 that are away from the support portion 11 and forming the fastening holes 120. The fastening holes 120 ensure a secure connection of the shoulder strap 5 and allow the shoulder strap 5 to be adjusted as needed to suit different usage scenarios. The support provided by the fastening portion 12 enhances the stability and resistance to interference of the shoulder strap 5, ensuring that the shoulder strap 5 does not loosen or shift even when dragged. Naturally, the fastening hole 120 may be provided through the fastening portion 12 along its width, and this application does not impose any further limitations.It should be noted that the connection between the shoulder strap 5 and the fastening hole 120 can be either by directly connecting the back of the shoulder strap 5 to the fastening hole 120, or by fixing a connecting strap 51 to the bottom of the shoulder strap 5 and further connecting the connecting strap 51 to the fastening hole 120. Because of the presence of the connecting strap 51, it is not necessary to frequently adjust the length of the shoulder strap 5, making operation easier.

[0032] Furthermore, referring to Figures 3 and 4, the first hole-forming portion 121 and the third hole-forming portion 123 extend diagonally in opposite directions such that the first hole-forming portion 121, the second hole-forming portion 122, and the third hole-forming portion 123 form a trapezoidal shape.

[0033] In this embodiment, since the first hole-forming portion 121, the second hole-forming portion 122, and the third hole-forming portion 123 form a trapezoidal shape, a larger connecting area is provided, allowing the shoulder strap 5 to remain stable even when subjected to relatively large tensile forces, and preventing damage due to excessive localized stress.

[0034] Specifically, the fastening holes 120 of the fastening portion 12 are provided to penetrate vertically, ensuring the stability and strength of the connection of the shoulder strap 5. The fastening portion 12 as a whole forms a trapezoidal structure, with the first hole-forming portion 121 and the third hole-forming portion 123 distributed symmetrically on both sides of the support portion 11, and the second hole-forming portion 122 connecting the ends of the first hole-forming portion 121 and the third hole-forming portion 123 that are away from the support portion 11. Therefore, not only is the overall strength of the fastening portion 12 increased, but the shoulder strap 5 can also receive the force evenly distributed when connected, effectively preventing the shoulder strap 5 from shifting or loosening due to uneven stress while being dragged. In addition, the first hole-forming portion 121 and the third hole-forming portion 123 extend diagonally in opposite directions, forming a stable trapezoidal shape together with the second hole-forming portion 122. The extended shapes of the first hole-forming portion 121 and the third hole-forming portion 123 may be straight, arc-shaped, or irregular, and this application does not impose any further limitations. The trapezoidal hooking portion 12 also provides a larger connection and stress area, so that the shoulder strap 5 remains stable even when subjected to relatively large tensile forces and is not damaged by excessive local stress. Furthermore, the diagonal extension design of the first hole-forming portion 121 and the third hole-forming portion 123 allows the shoulder strap 5 to naturally conform to the shape of the hooking portion 12 when connected, further improving the strength and reliability of the connection. This not only enhances the practicality and reliability of the telescopic rod component 1, but also improves its practicality and aesthetics, significantly increasing stability and durability during actual use and providing the user with a more convenient and safer user experience.

[0035] Furthermore, the support portion 11 comprises a first rod 111 and a second rod 112, the first rod 111 being provided in contact with the inside of the telescopic rod, the second rod 112 being provided above the first rod 111, and the latching portion 12 being connected to the second rod 112.

[0036] In this embodiment, the first rod 111 is provided in contact with the inside of the telescopic rod, ensuring a tight fit and providing a stable support base. The second rod 112 is located above the first rod 111, and the latching portion 12 is connected to the second rod 112, forming a continuous structural layout and ensuring overall stability and the strength of the connection.

[0037] Specifically, the support portion 11 is composed of a first rod 111 and a second rod 112, forming a robust support structure. The first rod 111 is provided in contact with the inside of the telescopic rod, and its inner wall fits with the inner wall of the telescopic rod. Its cross-section may be oval, elliptical, or the like. This application does not impose any further restrictions on its cross-section. Because the outer wall of the second rod 112 extends beyond the outer wall of the first rod 111, the bottom of the second rod 112 contacts the top of the telescopic rod, and the latching portion 12 is fixedly attached to the top of the telescopic rod, preventing the latching portion 12 from moving freely downward. The support portion 11 is provided with an insertion hole 110 that penetrates axially, and another telescopic rod is inserted through the insertion hole 110. This allows another telescopic rod to be movably attached inside this telescopic rod. In this case, the telescopic rod component 1 is provided at the joint of adjacent telescopic rods. The through-hole 110, which penetrates the support portion 11 axially, allows another telescopic rod to be inserted, enabling a movable mounting of the telescopic rod assembly 2. This not only enhances the flexibility of the telescopic rod assembly 2 but also provides adjustability, allowing the telescopic rod to be extended or adjusted as needed to suit different usage scenarios and user needs. The through-hole 110 further simplifies the installation and removal process of the telescopic rod assembly 2, improving ease of use.

[0038] Furthermore, the bottom of the first rod 111 is provided with a plurality of elastic grooves 1111, thereby giving the bottom of the first rod 111 a certain degree of elasticity so as to fit the inner wall of the telescopic rod.

[0039] In this embodiment, the telescopic rod component 1 is provided with a plurality of elastic grooves 1111 at the bottom of the first rod 111. This gives the bottom of the first rod 111 a certain degree of elasticity, thereby not only increasing the adhesion between the first rod 111 and the inner wall of the telescopic rod, but also providing better adaptability and ensuring a stable connection even in different usage environments.

[0040] Specifically, by providing the elastic groove 1111, the first rod 111 is allowed to deform slightly when subjected to external force, and therefore conforms better to the contour of the inner wall of the telescopic rod. When the telescopic rod assembly 2 is subjected to impact or vibration, friction and wear can be effectively reduced, extending the service life of the parts. On the other hand, the elastic groove 1111 also enhances the durability of the telescopic rod part 1, enabling it to maintain stable performance even under different temperature and humidity conditions. Furthermore, the elastic groove 1111 provides the first rod 111 with a certain degree of shock absorption effect, reducing the impact of vibrations generated while being dragged on the shoulder strap 5 and the telescopic rod assembly 2, and helping to further improve comfort and stability during use. With the elastic groove 1111, the telescopic rod part 1 is not only more functional, but also reaches a higher level in terms of aesthetics and practicality.

[0041] It should be noted that the opening of the elastic groove 1111 is located at the bottom of the first rod 111, and the depths of the multiple elastic grooves 1111 are, in this application, not limited further, and may be the same or different. The cross-section of the first rod 111 in this application is oval, and two long elastic grooves 1111 are provided symmetrically along the long axis of the first rod 111, and two short elastic grooves 1111 are provided symmetrically along the short axis of the first rod 111.

[0042] Furthermore, the first rod 111 is further provided with a plurality of locking blocks 1112 arranged symmetrically, and the locking blocks 1112 are locked and fixed within the locking grooves of the telescopic rod.

[0043] In this embodiment, the locking block 1112 on the first rod 111 fits precisely into the locking groove on the telescopic rod, ensuring that the telescopic rod component 1 is firmly locked to the telescopic rod. Therefore, it not only provides a reliable fixing effect but also allows the user to quickly attach and detach the telescopic rod component 1, significantly improving ease of use.

[0044] Specifically, the locking blocks 1112 are distributed symmetrically on both sides of the first rod 111, ensuring stability of the telescopic rod component 1 in all directions and preventing it from shifting or loosening while being dragged. Preferably, the locking blocks 1112 are provided symmetrically along the long axis of the first rod 111 and positioned relative to the short elastic groove 1111. This enhances the overall strength of the telescopic rod assembly 2, allowing it to withstand greater tensile and lateral forces and ensuring reliability in various usage scenarios. Furthermore, the tight fit between the locking blocks 1112 and the locking groove provides a certain degree of shock absorption, effectively reducing vibrations and noise generated while being dragged and improving user comfort. Such a locking method not only simplifies the installation process but also increases the degree of modularity of the telescopic rod assembly 2, allowing users to easily replace or upgrade the telescopic rod component 1 as needed to meet different usage requirements.

[0045] It should be noted that, if the material and shape of the locking block 1112 do not lose their fixing effect due to wear during long-term use, and the service life of the telescopic rod component 1 is extended, this application does not impose any further restrictions on them.

[0046] Furthermore, with reference to Figures 1 to 6, the present application further provides a backpack with a telescopic rod, comprising the telescopic rod component 1, pack body 3, base 4, and shoulder strap 5 described in any one of the above embodiments. The pack body 3 is fixedly attached to the base 4, the base 4 is provided with a telescopic rod assembly 2 and casters, and the telescopic rod component 1 is attached to the telescopic rod assembly 2. The shoulder strap 5 is provided on one side of the pack body 3, the shoulder strap 5 is provided with a connecting strap 51, and the end of the connecting strap 51 is fixedly connected to a hooking hole 120 of the telescopic rod component 1.

[0047] In this embodiment, the locking hole 120 provided in the telescopic rod component 1 connects to the shoulder strap 5 and forms a dynamic cooperative mechanism with the shoulder strap 5. When the telescopic rod assembly 2 is pulled up, the locking part 12 and the locking hole 120 cooperate to create a controllable vertical displacement of the shoulder strap 5, keeping it suspended above the ground. This effectively eliminates frictional contact between the bottom surface of the shoulder strap 5 and the ground, blocking the path for contamination to adhere. Furthermore, a dynamic safety distance is formed between the shoulder strap 5 and the caster, avoiding the risk of rolling interference due to entanglement of the shoulder strap 5, thereby simultaneously improving the smoothness of movement when dragged and the maintenance efficiency of the device.

[0048] Specifically, the backpack with a telescopic rod comprises a telescopic rod component 1, a pack body 3, a base 4, and shoulder straps 5, providing flexible use. The pack body 3 is firmly fixed to the base 4, which is equipped with a telescopic rod assembly 2 and casters, ensuring stability and convenience when the backpack is being dragged. The telescopic rod component 1 is attached to the telescopic rod assembly 2, and its unique structural design enables flexible connection and adjustment of the shoulder straps 5. A hooking hole 120 is provided in the hooking portion 12 of the telescopic rod component 1. The shoulder straps 5 are fixedly connected to the hooking hole 120 via a connecting strap 51, so that when the telescopic rod assembly 2 is pulled up, the shoulder straps 5 are also pulled up simultaneously, preventing the shoulder straps 5 from coming into contact with the ground or getting caught in the casters, thereby increasing safety and convenience when being dragged. The structural design of the hooking hole 120 ensures the strength and stability of the connection of the shoulder straps 5, and allows the user to adjust the position of the shoulder straps 5 as needed.

[0049] Furthermore, the support portion 11 of the telescopic rod component 1 ensures close contact and stable connection with the telescopic rod via the elastic groove 1111 and locking block 1112, thereby enhancing overall durability and reliability. Such a backpack with a telescopic rod not only improves the user experience but also optimizes and ensures stability and safety in various usage environments. Whether carried on the back or dragged, it can provide the user with a convenient and reliable solution.

[0050] It should be noted that, referring to Figures 5 and 6, the telescopic rod assembly 2 has a multi-layer structure that is a single telescopic rod comprising a first telescopic rod 21, a second telescopic rod, and a third telescopic rod 23, providing an adjustable length of the telescopic rod to suit the needs of different heights and usage scenarios. Specifically, the telescopic rod assembly 2 comprises a first telescopic rod 21, a second telescopic rod 22, and a third telescopic rod 23, the first telescopic rod 21 being fixedly attached to the base 4, the second telescopic rod being slidably attached to the first telescopic rod 21, the telescopic rod component 1 being fixedly attached to the top of the second telescopic rod, the third telescopic rod 23 being inserted through the insertion hole of the telescopic rod component 1 and slidably attached to the second telescopic rod, and a pull handle being provided at the top of the third telescopic rod 23.

[0051] The first telescopic rod 21 serves as the basic structure and is fixedly attached to the base 4, providing stable support and a reliable connection base. The second telescopic rod 22 is slidably attached to the first telescopic rod 21, allowing the user to adjust the overall length of the telescopic rod assembly 2 as needed to suit different heights and usage scenarios. The telescopic rod component 1 is fixedly attached to the top of the second telescopic rod 22, ensuring the stability of the latch 12 and the strength of the connection. The third telescopic rod 23 passes through the insertion hole of the telescopic rod component 1 and is slidably attached to the second telescopic rod 22, further enhancing the flexibility and adjustability of the telescopic rod assembly 2. A pull handle is provided at the top of the third telescopic rod 23, making it easier for the user to grasp and operate, and making dragging more effortless and convenient.

[0052] Such a multi-layer telescopic rod structure not only provides diverse adjustment options to meet the needs of different users, but the clever design of the telescopic rod component 1 ensures that it can be pulled up even while dragging the shoulder strap 5, avoiding contact with the ground or getting caught in the casters, thereby enhancing safety and convenience of use. The entire telescopic rod assembly 2 optimizes the user experience, allowing the backpack with telescopic rods to maintain excellent performance in various usage environments. It should be noted that the telescopic rod assembly 2 of this application may have two telescopic rod assemblies 2, and may be a double telescopic rod structure in which a pull handle connects the tops of the two telescopic rod assemblies 2.

[0053] Furthermore, one end of the connecting strap 51 is fixedly connected to the bottom of the shoulder strap 5, and the other end passes through the fastening hole 120 and is fixedly connected with adhesive tape on one side of the connecting strap 51.

[0054] In this embodiment, the other end of the connecting strap 51 passes through the latching hole 120 and is secured with adhesive tape. This simplifies operation and allows the user to quickly adjust the position of the shoulder strap 5, while also ensuring a strong connection and preventing loosening or shifting that may occur when dragged.

[0055] Specifically, one end of the connecting strap 51 is firmly fixed to the bottom of the shoulder strap 5, ensuring that it does not loosen or detach when subjected to tensile force. The other end of the connecting strap 51 passes through the hooking hole 120 and is secured with adhesive tape. This simplifies operation, allowing the user to quickly adjust the position of the shoulder strap 5, while also ensuring the strength of the connection and preventing loosening or shifting that occurs when dragged. The adhesive tape on the connecting strap 51 allows the length of the shoulder strap 5 to be easily adjusted as needed to suit different usage scenarios and user needs. When the telescopic rod assembly 2 is pulled up, the hooking part 12 passes through the hooking hole 120 and simultaneously pulls up the shoulder strap 5, suspending it in mid-air and preventing it from coming into contact with the ground or getting caught in the casters, improving drag safety and convenience. Designing the connecting strap 51 in conjunction with the hooking hole 120 not only increases flexibility in use but also enhances overall aesthetics and practicality, providing the user with a more convenient and reliable user experience.

[0056] It should be noted that the adhesive tape is provided on one side of the connecting strap 51, and the connecting strap 51 may be passed through the hooking hole 120, folded in half, and then adhered, or adhesive tape may be provided on the inside of the hooking hole 120, and the adhesive tape on the connecting strap 51 may be connected to the adhesive tape on the inside of the hooking hole 120. Naturally, there are various methods for fixing and connecting the end of the connecting strap 51 to the hooking hole 120 of the telescopic rod component 1. The connecting strap 51 includes adhesive tape, but is not limited to this, and may be connected with hooks, magnets, etc., and all of these are within the scope of protection of this application. Among these, it may also be fixed with other separately sold parts. For example, after the connecting strap 51 passes through the hooking hole 120, it may be fastened using a fastening device.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention, and it should be pointed out that those skilled in the art can make several further improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered to be within the scope of protection of the present invention.
