DETAILED DESCRIPTION

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0035] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The following is combined with Figure 2-6 This application is described in further detail.

[0037] The embodiment of the present application discloses an extended handle.

[0038] Example 1:

[0039] Reference Figure 2 The extension handle includes a connecting column 1, a connecting rope 2 and a connecting piece 3. The connecting column 1 is cylindrical and hollow. The connecting rope 2 includes two connecting heads 21 and an elastic rope 22. The two connecting heads 21 are respectively installed at both ends of the elastic rope 22.

[0040] Reference Figure 2 and Figure 3 The connecting member 3 includes a first connecting nut 31 and a connecting bolt 32. The first connecting nut 31 is welded and fixed in the connecting column 1. One end of the connecting bolt 32 is sequentially passed through one of the connecting heads 21 and the connecting column 1 and is threadedly connected to the first connecting nut 31. The other end abuts against the connecting head 21 so that the connecting head 21 is pressed tightly between the connecting bolt 32 and the connecting column 1.

[0041] When the connecting rope 2 needs to be replaced, the user can rotate the connecting bolt 32 to separate the connecting bolt 32 from the first connecting nut 31 to release the abutment against the connecting head 21, thereby achieving the disassembly of the connecting rope 2. Thereafter, the connecting bolt 32 is passed through the connecting head 21 and the connecting column 1, and the connecting bolt 32 is rotated to threadably connect with the first connecting nut 31, thereby achieving the installation of the connecting rope 2. The structure is simple and the operation is convenient, thereby facilitating the replacement of the connecting rope 2.

[0042] In some embodiments, a groove 211 is provided on the side of the connecting head 21 away from the connecting column 1, and the end of the connecting bolt 32 away from the first connecting nut 31 is embedded in the groove 211 to prevent the connecting bolt 32 from protruding from the connecting head 21, thereby ensuring the overall aesthetics of the extended handle, and reducing the contact between the connecting bolt 32 and the user, thereby reducing the occurrence of injuries to the user caused by the connecting bolt 32.

[0043] In some embodiments, the connecting member 3 also includes a second connecting nut 33, which is also welded and fixed in the connecting column 1. The first connecting nut 31 and the second connecting nut 33 are spaced apart along the length direction of the connecting bolt 32, so that the connecting bolt 32 is simultaneously threadedly connected to the first connecting nut 31 and the second connecting nut 33, effectively reducing the loosening of the connecting bolt 32, thereby improving the installation stability of the connecting head 21, thereby improving the installation stability of the connecting rope 2.

[0044] In some embodiments, the connector 21 and the elastic cord 22 are detachably connected, so that the elastic cord 22 can be replaced alone, thereby achieving the replacement of the connecting cord 2 , thereby reducing the replacement cost of the connecting cord 2 .

[0045] Reference Figure 4 In some embodiments, the connector 21 includes a base 212 and two elastic pressing pieces 213. The two elastic pressing pieces 213 are integrally connected to one end of the base 212 near the elastic cord 22, and the elastic cord 22 is compressed between the two elastic pressing pieces 213 and the base 212. During installation of the elastic cord 22, one end of the elastic cord 22 is placed on one side of the base 212, and force is applied to the elastic pressing pieces 213, causing the elastic pressing pieces 213 to deform and compress against the elastic cord 22, thereby achieving a detachable connection between the connector 21 and the elastic cord 22, which is simple and convenient to operate.

[0046] The implementation principle of this embodiment is: when the connecting rope 2 needs to be replaced, the user can rotate the connecting bolt 32 to separate the connecting bolt 32 from the first connecting nut 31 to release the abutment against the connecting head 21, thereby realizing the disassembly of the connecting rope 2, and then pass the connecting bolt 32 through the connecting head 21 and the connecting column 1, and rotate the connecting bolt 32 to threadably connect it with the first connecting nut 31, thereby realizing the installation of the connecting rope 2. The structure is simple and the operation is convenient, thereby facilitating the replacement of the connecting rope 2.

[0047] Example 2:

[0048] Reference Figure 5 and Figure 6 This embodiment is identical to the first embodiment in other structures, differing in the manner in which the connector 21 and the elastic cord 22 are detachably connected. Specifically, the connector cord 2 further includes a fastening nut 23, the number of which matches the number of connectors 21. The end of the connector 21 proximal to the elastic cord 22 is provided with a first threaded portion 214 and a plurality of deformation grooves 215 spaced apart along its circumference to facilitate expansion and deformation of the end of the connector 21. The fastening nut 23 is threadedly connected to the first threaded portion 214. In actual use, one end of the elastic cord 22 is inserted into the end of the connector 21 located in the deformation groove 215, causing the connector 21 to expand. The fastening nut 23 is then threadedly connected to the first threaded portion 214 to tighten the expanded portion of the connector 21, thereby compressing the elastic cord 22 and achieving a detachable connection between the connector 21 and the elastic cord 22. It should be noted that one end of the elastic cord 22 can be removed by rotating the fastening nut 23 , so that the elastic cord 22 can be replaced without removing the connecting bolt 32 .

[0049] In some embodiments, the connector 21 is provided with a second threaded portion 216 at the end of the first threaded portion 214 away from the elastic rope 22. When the fastening nut 23 is threadedly connected to the second threaded portion 216, the elastic rope 22 can be normally inserted into the connector 21, that is, the fastening nut 23 can be temporarily placed, and the loss of the fastening nut 23 can be avoided as much as possible.

[0050] In some embodiments, the connecting rope 2 further includes two fixing sleeves 24, which are respectively fixedly connected to the two ends of the elastic rope 22, making it easier for the elastic rope 22 to be inserted into the connector 21 and preventing the ends of the elastic rope 22 from being scattered.

[0051] The working principle of this embodiment is as follows: In actual use, one end of the elastic cord 22 is inserted into the end of the connector 21 located in the deformation groove 215, causing the connector 21 to be stretched. The fastening nut 23 is then threaded onto the first threaded portion 214 to compress the stretched portion of the connector 21, thereby tightening the elastic cord 22 and achieving a detachable connection between the connector 21 and the elastic cord 22. It should be noted that by rotating the fastening nut 23, one end of the elastic cord 22 can be removed, thereby allowing the elastic cord 22 to be replaced without removing the connecting bolt 32.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
