[0002] With the rapid development of technology, various smart wearable devices are permeating all aspects of people's lives, bringing tremendous changes to their daily experiences. Wearable devices are not merely hardware devices; they achieve their powerful functions through software support, data interaction, and cloud interaction. Their applications are very broad, including healthcare, fitness, and communication. For example, watches are no longer limited to simply telling time. By embedding intelligent hardware and running a smartphone operating system connected to the network, they can perform various functions such as making calls, sending text messages, emails, viewing photos, and listening to music and videos. Smartwatches are an extension and expansion of smartphone functions, bringing great convenience to people's daily lives.

[0003] When wearing a smartwatch, the case should fit snugly against the wrist for a secure fit and improved wearing experience. However, traditional watch straps are generally divided into buckle straps and separate chain straps. Buckle straps require disassembly and reassembly for each length adjustment, which is cumbersome and results in a poor user experience. Separate chain straps, on the other hand, have fixed-length individual links, requiring users to purchase additional parts or remove excess links for adjustment. This process is complex and may not always achieve the desired length, impacting the performance of the smartwatch.

[0004] Therefore, the inventors hope to solve the technical problem of how to further adjust the length of the watch strap within a small range without affecting the original adjustment method, so as to obtain a watch strap with a better wearing experience and a comfortable wearing effect.

[0049] In one embodiment, refer to the appendix to the specification. Figures 1 to 3The present invention provides an adjustable length head structure, comprising: a first head 1, a second head 2, and a button 3. One end of the first head 1 is provided with a slot 11, and a limiting part 12 is provided within the slot 11. The second head 2 is disposed within the slot 11 and is movable along the length direction of the first head 1. The button 3 is spring-loaded onto the second head 2 and is movable along the height direction of the second head 2. The button 3 is provided with a locking member 33, part of which extends into the slot 11. When the second head 2 moves away from the first head 1 to a first position, the locking member 33 is adapted to and connected with the limiting part 12, and the first head 1 and the second head 2 remain relatively fixed. When the button 3 is pressed towards the first head 1, the locking member 33 separates from the limiting part 12, and the second head 2 moves towards the first head 1 to a second position.

[0050] In this embodiment, the second end piece 2 is slidably disposed in the slot 11 of the first end piece 1. When the second end piece 2 moves away from the first end piece 1 to the farthest distance, that is, when the second end piece 2 is at its maximum extension position, the locking member 33 of the button 3 and the limiting part 12 on the first end piece 1 are locked. The first end piece 1 and the second end piece 2 remain relatively fixed. This state makes it convenient for the user to wear or remove the watch. When the button 3 is pressed towards the first end piece 1, the locking member 33 and the limiting part 12 are released from the locked state, and the second end piece 2 moves towards the first end piece 1 until it reaches the closest distance. At this time, the second end piece 2 and the first end piece 1 are in a free sliding state, and the length of the watch strap can be freely adjusted according to the thickness of the user's arm.

[0051] The novel and ingenious structure of this adjustable end link allows for automatic adjustment of the strap length within a small range without affecting the original strap adjustment method. This results in a better wearing experience and a more comfortable wearing effect. It also has the advantages of easy disassembly and assembly, convenient adjustment, and compatibility with traditional chain straps and soft rubber straps.
