[0002] Smart bracelets, smart watches and other wristband devices have become increasingly popular. In addition to their basic functions, wristband devices have also become an important element of dressing. As an essential component of wristband devices, users need to frequently replace straps to meet the needs of different occasions.

[0003] In traditional watch bands, tools or specific removal methods are usually required to install or remove the band. This may cause users to face difficulties and inconveniences when changing the band or adjusting the size. In addition, some watch band designs may require multiple parts and complex assembly steps, increasing manufacturing costs and difficulty in use. Utility Model Content

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] See also Figures 1 to 4 , which is a bilaterally retractable ear structure according to one embodiment of the present invention, is characterized in that it includes: a base 10, and an ear assembly 20 installed inside the base 10.

[0024] A through slot 11 is provided on one side of the base 10 along its length direction, and the through slot 11 runs through two opposite ends of the base 10. Two recesses 12 are provided at intervals on one side of the base 10 along its thickness direction, and the recesses 12 are connected to the through slot 11 downward.

[0025] In this embodiment, the concave portion 12 is configured in an oval shape, and the length direction of the concave portion 12 is consistent with the length direction of the through slot 11 .

[0026] The ear assembly 20 includes two telescopic rods 21 arranged in a mirrored manner, a spring 22 sandwiched between the two telescopic rods 21, and a shifting block detachably mounted on each telescopic rod 23; the telescopic rod 21 and the spring 22 are both located inside the through slot 11, and one end of each telescopic rod 21 away from the spring 22 is used to extend out of the end of the base 10, that is, the telescopic rod 21 can be extended or retracted into the base 10, so as to facilitate the removal and installation of the watch strap.

[0027] In this embodiment, the shift block 23 can be detachably mounted on the telescopic rod 21 after passing through the recess 12, and the position of the shift block 23 is relatively fixed to the position of the telescopic rod 21, so that the two telescopic rods 21 are independent of each other. This fixed relationship can make the operation of each telescopic rod 21 more controllable, and the user can more easily predict and master the telescopic process during use, which is convenient for the user to drive the telescopic rod 21 through the shift block 23, so as to easily remove or install the watch strap, greatly improving the user experience.

[0028] In this embodiment, the shift block 23 is set in an oval shape, and the corresponding limit of the shift block 23 is inside the recess 12, and the length of the shift block 23 is less than the length of the recess 12. The design of the shift block 23 and the recess 12 both presents an oval shape, which helps to reduce the gap between the shift block 23 and the recess 12, improves the stability of the shift block 23 inside the recess 12, reduces the shaking and friction during use, and makes the movement of the shift block 23 more precise and controllable. In actual work, operating a shift block 23 to dial back can drive the telescopic rod 21 corresponding to the shift block 23 to retract and compress the spring 22. Because the corresponding limit of the shift block 23 is inside the recess 12, it will not affect the other shift block 23 and the other telescopic rod 21, which greatly improves the flexibility of operation.

[0029] The above-mentioned bilaterally retractable ear structure has a simple structure and a disassembly scheme. Telescopic rods 21 are respectively installed on the opposite sides of the base 10. The two telescopic rods 21 are independent of each other. The telescopic rods 21 can be driven to retract by the shift block 23, which is convenient for users to easily remove the strap. A convenient disassembly mechanism and a simplified assembly process are provided, thereby improving the user experience and reducing manufacturing costs.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
