Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0025] like Figures 1-5 As shown, this embodiment discloses a top rod, which includes a first rod 1, a second rod 2, a handle 3, a handle 4, a support shaft 5, a lifting structure 6, and a locking device 7.

[0026] The first rod 1 is a hollow structure with an axially extending cavity inside. The outer diameter of the second rod 2 is smaller than the diameter of the cavity inside the first rod 1. Therefore, the first rod 1 can be slidably installed inside the cavity of the first rod 1. That is, a portion of the second rod 2 can enter the first rod 1. When the portion of the second rod 2 that enters the first rod 1 becomes longer, the overall length of the push rod becomes shorter. Correspondingly, when the portion of the second rod 2 that enters the first rod 1 becomes shorter, the overall length of the push rod becomes longer.

[0027] Install glove 3 at one end of the first rod 1 (in) Figure 1 The upper part of the handle 3 is hollow, used for mounting components such as the handle 4, support shaft 5, lifting structure 6, and locking device 7. Furthermore, a channel extending axially along the second rod 2 is provided inside the handle 3 to ensure that the second rod 2 can pass through and protrude from the handle 3.

[0028] In this embodiment, the handle glove 3 is a split structure, which makes it convenient to install the above-mentioned components inside the handle glove 3, and also makes it convenient to disassemble the handle glove 3 for repair when the top rod malfunctions.

[0029] The handle 4 includes a pressing part 41, a connecting part 42, and a supporting part 43 connected in sequence. An opening is also provided on one side of the handle glove 3, with the pressing part 41 protruding outside the handle glove 3 for easy operation. The connecting part 42 and the supporting part 43 extend into the handle glove 3 through the opening on one side. The connecting part 42 is rotatably connected to the housing of the handle glove 3. A mounting hole 421 is provided on the connecting part 42, and a receiving groove 431 communicating with the mounting hole 421 is provided on the supporting part 43. A supporting groove 432 communicating with the receiving groove 431 is provided below the receiving groove 431 on the supporting part 43.

[0030] More specifically, in this embodiment, the handle 4 is a one-piece structure, which improves the structural strength of the handle 4 and makes it less prone to damage. Furthermore, the pressing part 41 and the connecting part 42 of the handle 4 are set at an angle, so that force can be applied to the pressing part 41 of the handle 4 while gripping the handle glove 3, thereby facilitating the user's operation.

[0031] The support shaft 5 is disposed in the support groove 432 and partially extends into the receiving groove 431. The support groove 432 supports the support shaft 5 in multiple directions, that is, the support groove 432 provides continuous and uninterrupted support to the periphery of the support shaft 5.

[0032] The lifting structure 6 includes a main body 61 and a force-bearing part 62 that are connected to each other. The main body 61 is located in the mounting hole 421 and has a lifting hole. The force-bearing part 62 is located in the receiving groove 431 and can contact the support shaft 5.

[0033] A locking device 7 is installed inside the handle 3 to lock or release the second rod 2. Specifically, in this embodiment, the locking device 7 includes at least one locking piece arranged at a certain angle to the axial direction of the second rod 2, and the locking piece has a through hole through which the second rod 2 passes.

[0034] The second rod 2 passes through the channel and lifting hole inside the handle glove 3 and protrudes outside the handle glove 3. It applies a counterclockwise force to the pressing part 41 of the handle 4, which causes the connecting part 42 and the supporting part 43 to rotate counterclockwise synchronously. In turn, the support shaft 5 located in the supporting part 43 drives the force-receiving part 62 and the main body part 61 to move. While the main body part 61 is moving, it will come into close contact with the second rod 2. Under the action of friction, the second rod 2 will move out of the cavity of the first rod 1, thus increasing the overall length of the top rod. Furthermore, while the second rod 2 is moving, the locking device 7 will automatically release the second rod 2. After the second rod 2 has moved, the locking device 7 will automatically lock the second rod 2.

[0035] Furthermore, the lifting structure 6 in this embodiment also includes a friction reinforcement 63, one end of which is connected to the main body 61, and the other end extends downward and contacts the periphery of the second rod 2.

[0036] In this embodiment, a friction reinforcement member 63 is provided, which can enhance the friction between the lifting structure 6 and the second rod 2 when the main body 61 moves. The friction reinforcement member 63 increases the contact area between the main body 61 and the second rod 2, thereby providing greater friction during the lifting process. Furthermore, due to the presence of the friction reinforcement member 63, the wear that the second rod 2 may experience due to repeated movement is reduced, and the service life of the top rod is extended.

[0037] Furthermore, in this embodiment, the supporting part 43 and the pressing part 41 are located on both sides of the second rod 2, which can reduce the lateral dimension of the handle 4. The compact design makes the operation of the top rod more flexible in a narrow space, and also facilitates storage and transportation.

[0038] Furthermore, the top rod in this embodiment also includes a connector 8, which is installed inside the first rod 1 and connected to the handle 3. The connector 8 has a through hole for the second rod 2 to pass through.

[0039] In this embodiment, the connection 8 makes the connection between the first rod 1 and the handle 3 more secure.

[0040] Furthermore, in this embodiment, the connector 8 is provided with a first locking tooth 81 and a second locking tooth 82, the first rod 1 is provided with a first locking groove 11, and the glove 3 is provided with a second locking groove 31. The first locking tooth 81 is located in the first locking groove 11, and the second locking tooth 82 is engaged with the second locking groove 31. More specifically, there are two of each of the first locking tooth 81 and the second locking tooth 82, and correspondingly, there are also two of each of the first locking groove 11 and the second locking groove 31.

[0041] In this embodiment, the above-described structure not only enables the detachable connection between the glove 3 and the first rod 1, but also prevents rotation between the glove 3 and the first rod 1.

[0042] Additionally, the other end of the first rod 1 in this embodiment ( Figure 1 The lower part (represented by the middle) is equipped with an adjustable abutment plate 9. Of course, the second rod 2 protrudes from one end of the glove 3 ( Figure 1 The upper part (represented by the middle part) can also be equipped with the same type of abutment plate 9.

[0043] In this embodiment, an adjustable abutment plate 9 is provided, which can adapt to and support objects of different shapes and sizes, increasing the versatility and flexibility of the top rod. Users can easily adjust the angle of the abutment plate 9 as needed to adapt to different support requirements, thereby achieving precise positioning and support of the object. Furthermore, the increased support area of ​​the abutment plate 9 enhances the stability of the contact between the object and the top rod, reducing the risk of the object sliding or shifting during support.

[0044] In this embodiment, the push rod is provided with a support portion 43, and the support shaft 5 is disposed in the support groove 432 of the support portion 43. The support groove 432 supports the support shaft 5 in multiple directions, that is, the support groove 432 provides continuous and uninterrupted support to the periphery of the support shaft 5, so that the pressure on the support shaft 5 is evenly distributed and transmitted to the support portion 43. Under high load or long-term use, the shaft hole will not deform or be damaged due to excessive force, thus improving the service life of the push rod. In addition, in this embodiment, the support portion 43 and the pressing portion 41 of the handle 4 are respectively located on both sides of the second rod 2, which can effectively reduce the lateral dimension of the handle 4, making the operation of the push rod more flexible in confined spaces.
