The connecting tube 23 is arranged at the end of the telescopic tube 21, and the hose 22 is arranged in the connecting tube 23. In other words, the hose 22 passes through the connecting tube 23, and the hose 22 is suitable for sliding in the connecting tube 23 to perform a telescopic operation. Compared with the traditional arrangement, in the embodiment of the present application, by arranging the connecting tube 23 at the end of the telescopic tube 21, the hose 22 is prevented from sliding directly in the telescopic tube 21 to perform a telescopic operation, and the hose 22 is prevented from being easily stuck by the upper end of the telescopic tube 21 during the telescopic operation and the rotation operation, resulting in the telescopic operation and the rotation operation not being smooth.

[0041] Specifically, the telescopic tube 21 is composed of a plurality of sleeves, which are nested with each other to form the telescopic tube 21. For example, the telescopic tube 21 is defined to include a first sleeve 211, a second sleeve 212 and a third sleeve 213, that is, the connecting tube 23 is arranged in the first sleeve 211, the first sleeve 211 is nested in the second sleeve 212, and the second sleeve 212 is nested in the third sleeve 213. It should be understood by those skilled in the art that the number of the sleeves constituting the telescopic tube 21 is not a limitation of the present invention. The number of the sleeves constituting the telescopic tube 21 can be implemented as two, three, four or more.

[0042] In this embodiment, the first sleeve 211 is configured as a straight tube, and the second sleeve 212 includes a curved portion 2121 and a vertical portion 2122, wherein the curved portion 2121 is integrally connected to the upper end of the vertical portion 2122. Specifically, the curved portion 2121 extends in a tapered shape from the upper end of the vertical portion 2122, such that the inner diameter of the curved portion 2121 is smaller than the inner diameter of the vertical portion 2122. In addition, the inner diameter of the vertical portion 2122 gradually decreases from the lower end to the upper end, that is, the second sleeve unit 212 extends in a tapered shape. The second sleeve unit 212 also includes a recessed portion 2123, which extends inward from the surface of the vertical portion 2122. The recessed portion 2123 is annular, so that when the first sleeve 211 slides from the second sleeve 212, the fit between the outer wall of the first sleeve 211 and the inner wall of the second sleeve 212 is increased, thereby improving the stability of the telescopic tube 21.

[0043] Similarly, the structure of the third sleeve 213 is similar to that of the second sleeve 212. The third sleeve 213 includes a curved portion 2121, a vertical portion 2122 and a recessed portion 2123. The curved portion 2121 extends in a tapered shape from the upper end of the vertical portion 2122, so that the inner diameter of the curved portion 2121 is smaller than the inner diameter of the vertical portion 2122. In addition, the inner diameter of the vertical portion 2122 gradually decreases from the lower end to the upper end. The recessed portion 2123 extends inwardly from the surface of the vertical portion 2122. The recessed portion 2123 is annular, so that when the second sleeve 212 slides from the third sleeve 213, the fit between the outer wall of the second sleeve 212 and the inner wall of the third sleeve 213 is increased, thereby improving the stability of the telescopic tube 21.

[0044] In addition, the first sleeve 211, the second sleeve 212 and the third sleeve 213 are all configured to be in a reduced shape, the outer diameter of the end of the first sleeve 211 is larger than the inner diameter of the curved portion 2121 of the second sleeve 212, and the outer diameter of the end of the second sleeve 212 is larger than the inner diameter of the curved portion 2121 of the third sleeve 213, thereby achieving the telescopic function of the telescopic tube 21.

[0045] The telescopic tube 21 also has a telescopic channel 214, that is, the first sleeve 211, the second sleeve 212 and the third sleeve 213 are all hollow tubes, the first sleeve 211, the second sleeve 212 and the third sleeve 213 are interconnected to form the telescopic channel 214, and the connecting tube 23 is arranged in the telescopic channel 214.

[0046] The hose 22 includes a hose body 221, a stopper 222 and an extension 223. The stopper 222 is disposed at the end of the hose body 221. When the hose body 221 is extended and retracted from the connecting tube 23, when the hose body 221 is stretched to the maximum extent, the stopper 222 abuts against the connecting tube 23, thereby limiting the hose body 221 and preventing the hose body 221 from being pulled out of the connecting tube 23. The extension 223 is disposed at the front end of the hose body 221 to connect to the lamp body assembly 10, that is, the hose body 221 is connected to the lamp body assembly 10 through the extension 223.

The connecting pipe body 231 is arranged at the end of the first sleeve 211.

[0049] It is worth mentioning that, in this embodiment, the first sleeve 211 of the telescopic tube 21 includes a first recessed unit 2111, which extends inwardly in an annular recess from the outer wall of the head end of the first sleeve 211, and the connecting tube 23 also includes a second recessed unit 233, which extends inwardly in an annular recess from the outer wall of the head end of the connecting tube 23. In other words, by compressing the first sleeve 211 and the connecting tube 23 at the same time, the first recessed unit 2111 and the second recessed unit 233 are formed, so that the first sleeve 211 and the connecting tube 23 remain relatively stable.

[0050] In this embodiment, the connecting tube 23 further includes an abutment portion 234, and the abutment portion 234 protrudes outward from the head end of the connecting tube 23, that is, the outer diameter of the head end of the connecting tube 23 is greater than the outer diameter of the terminal end thereof, the outer diameter of the head end of the connecting tube 23 is greater than the outer diameter of the head end of the first sleeve 211, and the outer diameter of the terminal end of the connecting tube 23 is smaller than the outer diameter of the head end of the first sleeve 211. When the connecting tube 23 is installed in the first sleeve 211 of the telescopic tube 21, the connecting tube 23 is directly installed in the first sleeve 211 from top to bottom. Then, by compressing the first sleeve 211 and the connecting tube 23 at the same time, the first recessed unit 2111 and the second recessed unit 233 are formed, so that the first sleeve 211 and the connecting tube 23 remain relatively stable.

[0051] In addition, the upper and lower ends of the connecting tube 23 are chamfered, which is more conducive to the telescopic operation and rotation operation of the hose 22. That is, the connecting tube 23 also includes two rounded corners 235, which are arranged at the upper and lower ends of the connecting tube 23, which is conducive to the telescopic operation and rotation operation of the hose 22, and helps to prevent the hose 22 from being worn and scratched.

[0052] The handle assembly 30 includes a handle shell 30 and a storage cavity 32. The storage cavity 32 is disposed in the handle shell 30. The telescopic tube 21 is installed in the storage cavity 32 and connected to the handle shell 30. The handle shell 30 is used to be held by a user.

[0053] In summary, the telescopic lamp 1 arranges the connecting tube 23 at the end of the telescopic tube 21, thereby preventing the hose 22 from sliding directly in the telescopic tube 21 for telescopic operation, and preventing the hose 22 from being easily stuck by the upper end of the telescopic tube 21 during telescopic and rotation operations, resulting in the problem that the telescopic and rotation operations are not smooth enough. Therefore, the telescopic lamp 1 can perform smooth telescopic and rotation operations, which is convenient for users to use.

[0067] Based on this, in this embodiment, when installing the connecting tube 23A in the first sleeve 211A of the telescopic tube 21A, it is necessary to place a fixture in the first sleeve 211A first, and then install the connecting tube 23A in the first sleeve 211A. Then, by compressing the first sleeve 211A and the connecting tube 23A at the same time, the first recessed unit 2111A and the second recessed unit 233A are formed, so that the first sleeve 211A and the connecting tube 23A remain relatively stable.

[0068] In summary, the telescopic lamp 1 arranges the connecting tube 23A at the end of the telescopic tube 21A, thereby preventing the hose 22A from sliding directly in the telescopic tube 21A for telescopic operation, and preventing the hose 22A from being easily stuck by the upper end of the telescopic tube 21A during telescopic and rotation operations, resulting in the problem that the telescopic and rotation operations are not smooth enough, so that the telescopic lamp 1A can perform smooth telescopic and rotation operations, which is convenient for users to use.
