[0066] The design, through the matching of the insertion rod 3 and the insertion hole 4, along with the spring 6 and the stop block 7 in the limiting component, ensures that when the insertion rod 3 is inserted into the insertion hole 4, the stop block 7 pops out of the groove 5 under the elastic force of the spring 6, engaging with the edge of the insertion hole 4 to form a double fixation, avoiding the loosening problem of traditional Velcro or buckles. The inclined structure of the stop block 7 facilitates the smooth insertion of the insertion rod 3 while ensuring that it is not easy to fall off after engagement, significantly improving the stability of the bracelet.

[0067] like Figure 4 and Figure 5 As shown, the limiting component includes a spring 6 fixedly connected to the side wall of the groove 5. A stop 7 is fixedly connected to the end of the spring 6 away from the center of the insertion rod 3. The stop 7 is adapted to the notch. In the initial state, the stop 7 extends to the outside of the groove 5. A reset component is provided on the end face of the insertion rod 3. The end face of the stop 7 has an inclined structure.

[0068] Among them, the spring 6 and the stop block 7 of the limiting component form an automatic locking mechanism, which eliminates the need for users to manually press and lock, reducing the difficulty of operation and making it suitable for the elderly with weak hand coordination or infants who cannot cooperate independently. The reset component on the end face of the plug 3 is linked with the limiting component to form a "lock-unlock" closed loop. The lock can only be released through specific operations to prevent users from accidentally disassembling the device and ensure that the bracelet can be worn continuously.

[0069] like Figure 4 As shown, the reset assembly includes a keyhole 8 opened on the end face of the insertion rod 3. A movable plate 9 is movably connected inside the keyhole 8. Two pull ropes 10 are fixedly connected to the side wall of the movable plate 9. Two through holes are opened on the side wall of the keyhole 8. The through holes are respectively connected to the grooves 5 on both sides. The other end of the pull ropes 10 are respectively connected to the stop blocks 7 on both sides.

[0070] Specifically, the keyhole 8 of the reset component is designed as a dedicated unlocking channel. A corresponding tool (such as a key) must be inserted and pressed against the movable plate 9. The pull cord 10 then simultaneously pulls the two side blocks 7 back into the groove 5, unlocking the device. This design controls unlocking authority to caregivers, preventing elderly individuals or infants from disassembling and losing the bracelet themselves. The two pull cords 10 are connected to the two side blocks 7 respectively, ensuring that the two side blocks 7 retract synchronously during unlocking. This avoids jamming or structural damage caused by unlocking from one side, improving the smoothness of the unlocking operation. The connection between the keyhole 8 and the through hole allows the pull cord 10 to be hidden inside the insertion rod 3, preventing the pull cord 10 from being exposed, worn, or tangled, ensuring long-term reliability.

[0071] like Figure 4As shown, two storage slots 11 are provided on the side wall of the keyhole 8. When the movable plate 9 moves downward, the pull rope 10 can be located in the storage slot 11 to avoid interference between the two.

[0072] like Figure 3 and Figure 4 As shown, a circular groove 12 is provided on the end face of the insertion rod 3, and a rubber pad 13 is movably connected in the circular groove 12. A sealing block 14 is fixedly connected to the side wall of the rubber pad 13, and the sealing block 14 is inserted into the keyhole 8. A force-bearing groove 15 is provided on the side of the rubber pad 13.

[0073] The rubber pad 13 is used to seal and protect the keyhole 8 at the end of the plug rod 3, preventing water and dust from entering during daily use, thereby improving its practicality.

[0074] The working principle of this utility model is as follows: When wearing the bracelet, the display 1 is placed against the wrist, and then the wristbands 2 on both sides are tightened so that the plug 3 is inserted into the appropriate socket 4. At the same time, the inclined surface of the stop block 7 is used to retract it into the groove 5, and the spring 6 is compressed. After the plug 3 passes through the socket 4, the spring 6 is used to push the stop block 7 back to its original position and insert it into the notch, which limits and fixes the plug 3, preventing the elderly or children from accidentally taking off the bracelet and ensuring that the bracelet is in a stable state during the wearing process.

[0075] When the wristband needs to be removed, the rubber pad 13 is opened through the force groove 15, the corresponding key is inserted into the keyhole 8, and the key is pressed down, thereby squeezing the movable plate 9 to move downward. The movable plate 9 pulls the pull rope 10 downward, so that the other end of the pull rope 10 pulls the stop block 7 into the groove 5, releasing the fixation of the insertion rod 3, making it easy to remove the wristband 2.

[0076] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
