The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

As shown in fig. 1, 2 and 3, the overall structure of the connection structure for the watchband includes a key 1, an elastic element 2, a support cover 3 and a base 4, the support cover 3 is matched with the base 4, the support cover 3 is provided with a key slot 31, the top of the key 1 extends out of the support cover 3, a through slot penetrates through the front portion 41 of the base, a support limit block 43 is arranged at the rear portion 42 of the base, two ends of the elastic element 2 extend to two ends of the through slot, an inner ring 21 of the elastic element is sleeved on the support limit block 43, and the bottom of the key 1 can extend into the inner ring 21 of the elastic element in a vertically sliding manner to drive two ends of the elastic element 2 to contract and expand along a radial direction.

In a specific embodiment, as shown in fig. 4, the two ends of the elastic element 2 are rigidly connected with pins 22, the pins 22 are rigidly connected with the two ends of the elastic element 2, and the pins 22 are driven to move along the axial direction of the through groove by the change of the diameter of the inner ring 21 of the elastic element. The pressing of the key 1 drives the two ends of the elastic element 2 to contract and expand, so that the structure is simple, and the replacement of the watchband and the watch body can be easily completed by changing the problem that the traditional lug is difficult to detach and install.

In a preferred embodiment, the base 4 and the bracket cover 3 are fixed by laser welding, and may also be fixed by strong glue.

As shown in fig. 5, the bottom 12 of the key is a tapered structure with a gradually decreasing cross-sectional area. The downward pressure on the keys 1 increases gradually, and the bottom parts 12 of the keys gradually extend into the inner ring 21 of the elastic element, and the larger the contact area between the bottom parts 12 of the keys and the elastic element 2 is, the larger the expansion force can be generated on the inner ring 21 of the elastic element.

In a preferred embodiment, the bottom of the key 1 is a cone frustum, the sectional area of the upper part of the cone frustum is larger than that of the lower part, the diameter of the section of the upper part of the cone frustum is larger than the inner diameter of the inner ring 21 of the elastic element, and the lower part of the cone frustum firstly extends into the inner ring 21 of the elastic element. At this time, the tapered circular truncated cone is a tapered circular truncated cone with a large upper part and a small lower part, after the small side enters the inner ring 21 of the elastic element, the contact area between the tapered circular truncated cone and the elastic element 2 is gradually increased, the larger the tension received by the inner ring 21 of the elastic element is, the larger the tightening force generated on the two ends of the elastic element 2 is, and finally, the larger the downward acting force of the key 1 is, the larger the tightening force generated on the elastic element 2 is, and vice versa, the smaller the tightening force is.

In a specific embodiment, as shown in fig. 6, a groove 121 matching with the support stopper 43 is provided in the tapered circular truncated cone. The supporting stopper 43 is used to fix the elastic element 2 and support the elastic element 2, so that a certain space is formed between the base 4 and the elastic element 2, and the bottom 12 of the key can slide up and down in the space.
