The installation rods 24 are slidably installed inside the installation holes 11. A baffle 4 is integrally formed at one end of the bottom plate 10. The baffle 4 and the partition 5 can effectively cover the structure inside the bottom plate 10, preventing foreign objects from falling into the bottom plate 10 and causing the telescopic arm 21 to be unusable.

[0030] Principle of use and advantages: When in use, by pressing the push button 2, the slider fixed at the bottom of the push button 2 will move, driving the telescopic arm 21 to move forward. The connecting block installed at one end of the telescopic arm 21 will push the rectangular plate 14, and the rectangular plate 14 is installed on one side of the L-shaped rod 20. In this way, the L-shaped rod 20 will move to drive the rotating block 6 to rotate. Finally, while the rotating block 6 is rotating, it will drive the moving rod 7, and the movement will move into the interior of the frame 3. In this way, the key or other items to be buckled can be buckled into the interior of the frame 3, which can improve the moving speed of the moving rod 7 and protect the surface of the moving rod 7, preventing the phenomenon of paint peeling and scratches on the surface of the moving rod 7. Then, when the push button 2 is released, the moving rod 7 will return to its original position, which can effectively improve the mobility of the keychain and can be used flexibly. Since the bottom of the sliding plate 26 is fixedly installed with the second spring 15, and the second spring 15 is installed inside the sliding port 16, in this case, when the push button 2 is released, the second spring 15 will quickly rebound to move the telescopic arm 21 back and forth, which can effectively reset the moving rod 7. Then, a first spring 12 is installed at one end of the L-shaped plate, and one end of the first spring 12 is installed inside the frame 3. The first spring 12 assists the second spring 15 to reset the moving rod 7, ensuring that the moving rod 7 can achieve the effect of automatic reset and preventing the moving rod 7 from getting stuck inside the frame 3. The baffle 4 and the partition 5 can effectively cover the structure inside the bottom plate 10, preventing foreign objects from falling into the bottom plate 10 and causing the telescopic arm 21 to be unable to be used.
