[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 4As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1: A replaceable trolley handle includes a suitcase 1, with a pulley 6 mounted on the bottom of the suitcase 1 and a mounting base 4 on the suitcase 1. A telescopic handle 3 is mounted on the suitcase 1 via the mounting base 4. A strong magnet 302 is provided on the back of the telescopic handle 3. A groove 404 is formed in a slot 403. After the telescopic handle 3 is engaged in the slot 403, the strong magnet 302 and the groove 404 attract each other, further defining its position. The mutual attraction between the strong magnet 302 and the groove 404 further enhances the stability of the telescopic handle 3 within the slot 403. This design effectively prevents the telescopic handle 3 from shaking or falling off during use, thereby improving the overall stability of the suitcase. Through the attraction of the strong magnet 302, users can more easily engage the telescopic handle 3 in the slot 403, simplifying the installation process and improving user convenience. In some cases, such as when the suitcase is subjected to external impact or bumps, the mutual attraction between the strong magnet 302 and the groove 404 provides additional safety protection. This design helps prevent the telescopic pull rod 3 from accidentally falling off due to external forces, thus protecting the safety of the suitcase and its contents. A handle 2 is installed at the top of the telescopic pull rod 3, and a pin hole 301 is provided on the inner side of the telescopic pull rod 3. Slots 403 are provided on both sides of the fixing base 4. The telescopic pull rod 3 is secured to the fixing base 4 through the slots 403. The fixing base 4 has a receiving groove 401 with a fixing hole 402 inside. The fixing base 4 is connected and fixed to the suitcase 1 through the fixing hole 402 and bolts. Positioning modules 5 are installed in the receiving groove 401 of the fixing base 4. Two positioning modules 5 are installed in the receiving groove 401, symmetrically distributed on both sides of the fixing hole 402. This symmetrical distribution ensures that the telescopic pull rod 3 can be accurately positioned to the predetermined position when inserted into the fixing base 4. This design helps improve the overall structural precision of the suitcase, allowing users to experience a smoother and more stable operation. The symmetrical distribution also simplifies the installation and removal of the positioning modules 5. Users can easily replace or maintain the positioning module 5 without complicated operations, which reduces maintenance and time costs.

[0040] Example 2: To lock the telescopic rod 3, for example, as follows Figures 1 to 4As shown, the present invention further includes: a fixing plate 502 for the positioning module 5, the positioning module 5 being fixed in the receiving groove 401 by the fixing plate 502, the fixing plate 502 securely fixing the positioning module 5 in the receiving groove 401, ensuring that the positioning module 5 will not shake or fall off during use. The design of the fixing plate 502 makes the installation process of the positioning module 5 simpler. The fixing plate 502 securely fixes the positioning module 5 within the receiving groove 401, helping to ensure accurate positioning of the positioning module 5 during operation. The fixing plate 502 is equipped with a limiting rod 501, on which a pin 505 is fitted. One end of the pin 505 is connected to a connecting plate 503. A spring 504 is fitted on the limiting rod 501 between the connecting plate 503 and the pin 505. The pin 505 is pushed into the pin hole 301 of the telescopic pull rod 3 by the spring 504, automatically locking the pull rod. This design simplifies user operation, eliminating the need for manual fixing or additional locking mechanisms, thus improving ease of use. The pin 505, tightly inserted into the pin hole 301 under the action of the spring 504, ensures a stable connection between the telescopic pull rod 3 and the fixing base 4. This design effectively prevents the pull rod from shaking or falling off during use, improving the overall stability of the suitcase. The self-locking pin 505 design enhances the security of the suitcase. Even on uneven surfaces or under impact, the pin 505 maintains a tight connection, preventing the handle from accidentally detaching and protecting the luggage. The mounting base 4 has a through hole 405 through which the pin 505 passes and inserts into the pin hole 301, forming a robust connection structure. This design helps enhance the overall stability of the suitcase, preventing wobbling or detachment during use. This design can accommodate telescopic handles 3 and mounting bases 4 of different sizes. It can be adapted to different suitcase models, improving design flexibility and applicability. The pin 505 interlocks with the pin hole 301 to lock the telescopic handle 3 installed in the mounting base 4.

[0041] Working principle:

[0042] The telescopic rod 3 is initially positioned by being attracted to the groove 404 in the fixing base 4 by a strong magnet 302 on its back. This design not only enhances the stability of the rod but also makes it less likely to fall off under external force. A pin hole 301 is provided on the inner side of the telescopic rod 3, while slots 403 are provided on both sides of the fixing base 4. When the telescopic rod 3 is engaged in the slot 403, the pin 505 (pushed by a spring 504) inserts into the pin hole 301, thereby locking the telescopic rod 3. This locking mechanism ensures the stability of the rod during use.

[0043] The positioning module 5 is installed in the receiving groove 401 of the fixed base 4 via the fixing plate 502. Each positioning module 5 is equipped with components such as a limit rod 501 and a pin 505. When the telescopic rod 3 is locked on the fixed base 4, the pin 505 will insert into the pin hole 301 of the telescopic rod 3. At this time, the limit rod 501 and the pin 505 in the positioning module 5 work together to ensure that the rod will not accidentally loosen or fall off.

[0044] This easily replaceable suitcase handle solution achieves stable fixation, easy adjustment, and convenient installation through a unique structural design and the interaction between its components. These features not only enhance the practicality and convenience of the suitcase but also provide users with a safer and more comfortable travel experience. Furthermore, the solution is easy to replace and maintain, reducing users' repair costs and time.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
