Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0034] This application discloses a telescopic roller handle. (Refer to...) Figure 1-2 The telescopic roller handle includes a fork section 1, a first sleeve 2, a middle sleeve 3, and a tail sleeve 4. The first sleeve 2 is detachably mounted on the end of the fork section 1. The middle sleeve 3 is slidably mounted in the first sleeve 2, and the length of the middle sleeve 3 is less than the length of the first sleeve 2. The tail sleeve 4 is slidably mounted in the middle sleeve 3, and the length of the tail sleeve 4 is less than the length of the middle sleeve 3. The central axes of the first sleeve 2, the middle sleeve 3, and the tail sleeve 4 coincide.

[0035] In this embodiment, the end of the first sleeve 2 is provided with a threaded section 21, and the end of the fork portion 1 is provided with a threaded groove 11. The threaded section 21 is detachably threaded into the threaded groove 11.

[0036] The outer diameters of the middle sleeve 3 and the tail sleeve 4 gradually decrease from one end to the other. The inner diameter of the end of the first sleeve 2 away from the fork 1 is smaller than the maximum outer diameter of the middle sleeve 3 to restrict the slippage of the middle sleeve 3. The minimum inner diameter of the middle sleeve 3 is larger than the maximum outer diameter of the tail sleeve 4 to restrict the slippage of the tail sleeve 4. The inner diameter of the threaded section 21 is larger than the maximum outer diameter of the middle sleeve 3.

[0037] The first sleeve 2, the middle sleeve 3, and the tail sleeve 4 designed above have a simple structure, are easy to assemble, and are relatively easy to stretch or shrink.

[0038] To address the issue of the middle sleeve 3 and the tail sleeve 4 easily wobbling when the telescopic roller handle is in the retracted state, a fixing element 5 is detachably installed in the threaded section 21. The fixing element 5 is used to fix the middle sleeve 3 and the tail sleeve 4 in the retracted state. The fixing element 5 is a magnetic block, and the middle sleeve 3 and the tail sleeve 4 are made of ferromagnetic material. The magnetic block is magnetically fixed to the ends of the middle sleeve 3 and the tail sleeve 4. Specifically, the fixing element 5 is a circular thin disc structure, and the fixing element 5 is detachably snapped and fixed to the inner circumferential wall of the threaded section 21.

[0039] In this embodiment, to prevent the handle's edges and corners from being too sharp and causing injury, the end of the tail sleeve 4 away from the fork 1 is sealed and has a rounded end 41. The outer periphery of the end of the first sleeve 2 away from the fork 1 is provided with a first conical transition surface 23, and the outer periphery of the end of the middle sleeve 3 away from the fork 1 is provided with a second conical transition surface 31, thereby effectively improving product safety.

[0040] To facilitate gripping and holding the handle, the first sleeve 2 has arc-shaped grooves 22 on both sides to accommodate finger clamping.

[0041] The beneficial technical effects of the telescopic roller handle in this application embodiment are roughly as follows:

[0042] The long handle is divided into a four-section structure, and the middle sleeve 3 and the tail sleeve 4 can be slidably retracted into the first sleeve 2. The first sleeve 2 can be removed to easily install the middle sleeve 3 and the tail sleeve 4 into the first sleeve 2. When in use, the middle sleeve 3 and the tail sleeve 4 can be slid out. Their length will not affect the normal operation of the handle. When carrying and storing, they can be easily loaded into a small cosmetic bag, which has the advantage of being easy to carry.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
