The second docking assembly 63 includes a second engaging member 65, a second slide block 66, and a fitting member 67 connected between the second engaging member 65 and the second slide block 66. The second engaging member slides along with the second slide block.

The second control button 64 extends out of the base 62 and can be pressed backward and automatically returns forward when not pressed.

As shown in FIGS. 10 to 13, the strap link 60 further includes a second housing 61. The second housing 61 has a first mounting position 611 for mounting the base 62, a second mounting position 612 for mounting the second docking assembly 63, and a second mounting position 612 for mounting the second control button 64. The first mounting position 611 is spaced apart from the second mounting position 612. The third mounting position 613 faces and is connected to the first mounting position 611.

The base 62 has a positioning chamber 621, a positioning post 622, and a positioning portion 623. The positioning post 622 and the positioning portion 623 are located beside the positioning chamber 621. The positioning portion 623 has a curved recess 624.

This embodiment includes two second docking assemblies 63. A third elastic member 68 and a fourth elastic member 69 are connected between the two second docking assemblies 63. The two second docking assemblies 63 each include the second engaging member 65, the second slide block 66, and the fitting member 67 connected between the second engaging member 65 and the second slide block 66. The second engaging member 65 slides along with the second slide block 66. A third connecting portion protrudes from the inner side of the fitting member 67. The third elastic member 68 is disposed on the third connecting portion for pushing the second engaging member 65 to slide along the positioning chamber 621. When the second engaging member 65 is mounted in the second mounting position 612, the other end of the second engaging member 65 can be extended out of the second housing 61 or retracted into the second housing 61.

The second engaging member 65 is integrally formed on the outside of the fitting member 67. The second engaging member 65 is integrally formed with the fitting member 67, so that they can be molded in one piece directly through the mold. Compared with the assembled structure, it is simpler and easier to mold the second engaging member 65 integrally formed with the fitting member 67, and the second engaging member 65 has higher structural strength.

The second slide block 66 has an inclined arc portion 661 and a fourth connecting portion. The fourth connecting portion protrudes from the inner side of the second slide block 66. The fourth elastic member 69 is disposed on the fourth connecting portion for pushing the second slide block 66 to slide along the positioning chamber 621.

One end of the second engaging member 65 is located in the curved recess 624. The base 62 and the second docking assembly 63 are mounted in the first mounting position 611 and the second mounting position 612, respectively.

The second control button 64 has a button body 641 and two curved blocks 642 on the left and right sides of the bottom of the button body 641. The button body 641 has a positioning hole 643 for insertion of the positioning post 622. The second control button 64 extends out of the third mounting position 613 and can be pressed backward and automatically returns forward when not pressed. The button body 641 and the two curved blocks 642 are located in the third mounting position 613. When the second control button 64 is pressed backward, the curved block 642 slides on the inclined arc portion 661 so that the second slide block 66 moves inwardly and enables the second engaging member 65 to retract in the second housing 61. By the curved block 642 of the second control button 64 being pressed against the inclined arc portion 661, the contact area between the curved block 642 of the second control button 64 and the inclined surface of the second slide block 66 is reduced, thereby reducing the friction between the second control button 64 and the second slide block 66, and subsequently reducing the pressing force required. The operation is more effortless. Besides, the installation or removal of the strap links 60 is simple, easy and quick and does not require the use of external tools, which saves time and effort, realizes easy and quick dismantling and replacement. It is easy to adjust the length of the watch strap. Through the third elastic member 68 and the fourth elastic member 69, the second slide block 66 and the fitting member 67 is provided with sufficient return force or holding force to improve the connection between the adjacent strap links 60, so as to prevent them from coming loose.

When it is necessary to adjust the length of the watch strap, the second control button 64 is pressed down, and the curved block 642 slides obliquely downward on the inclined arc portion 661 to move the positioning hole 643 up and down along the positioning post 622, such that the second slide block 66 moves inwardly and enables the second engaging member 65 to retract in the second housing 61. At this time, both the third elastic member 68 and the fourth elastic member 69 are in a compressed state.

When the second control button 64 is released, under the return force of the third elastic member 68 and the fourth elastic member 69, the second slide block 66 moves outward and drives the second engaging member 65 to move outward. At the same time, the curved block 642 moves obliquely upward along with the movement of the inclined arc portion 661, and then the second control button 64 is returned.

The first end of the strap connector 50 has a mating groove 58 corresponding to the second engaging member 65. The second docking assembly extends in the mating groove 58 so that the second engaging member is engaged in the mating groove.
