Specifically, the band in this embodiment includes a band body 1 and a connection device 3, where the band body 1 is locked and fixed to the watch case 2 by the connection device 3, and the band body 1 is connected to the watch case 2 in a quick release manner.

Referring to fig. 2, the band body 1 includes a band bead 11, and the connecting means 3 is mounted on the band bead 11 to fix the band bead 11 to the watch case 2. The connecting device 3 comprises a spring expansion assembly 31, an elastic switch assembly 32 and a driving assembly 33, and the driving assembly 33 is connected with the spring expansion assembly 31, so that the spring expansion assembly 31 can expand and contract along the length direction perpendicular to the watchband under the driving of the driving assembly 33, and the spring expansion assembly 31 is clamped to the watch case 2 to achieve the quick-release function.

Specifically, when the driving assembly 33 is movably clamped to the elastic switch assembly 32, the free end of the spring expansion assembly 31 extends out to two side surfaces of the watchband head bead 11 in the direction perpendicular to the length direction of the watchband to be fixedly connected to the watch case 2, and meanwhile, the driving assembly 33 is prevented from retracting by the elastic switch assembly 32 in a limiting and fixing mode, so that the free end of the elastic switch assembly 32 can be reliably clamped to the watch case 2, and the connection stability of the watchband body 1 and the watch case 2 is ensured.

In addition, when the driving assembly 33 moves in a direction away from the elastic switch assembly 32, the elastic switch assembly 32 is pressed by the driving assembly 33, so that the elastic switch assembly 32 is elastically deformed, and the limiting function of the elastic switch assembly 32 on the driving assembly 33 is disabled. Furthermore, the driving assembly 33 is far away from the elastic switch assembly 32, so that the spring expansion assembly 31 is retracted into the watchband head bead 11 to release the connection between the connecting device 3 and the watch case 2, thereby achieving the disassembling and assembling function.

Above-mentioned watchband is through setting up spring expansion element 31, elastic switch subassembly 32 and drive assembly 33, can effectively simplify overall structure when reaching the dismouting function, and improve structural design's rationality, when using like this, only need the application of force to order about drive assembly 33 and remove, make drive assembly 33 joint to or break away from out elastic switch subassembly 32, can realize the dismouting operation between watchband main part 1 and the wrist-watch watchcase 2, the convenience of operation has been improved greatly, make the operation simple more convenient.

In addition, when the disassembly and assembly operation is carried out, the driving can be realized only by applying force on the driving assembly 33, and large force is not needed, so that the operation driving difficulty is reduced, and the problem of clamping damage caused by applying large force is solved.

Therefore, when the driving assembly 33 is disengaged from the elastic switch assembly 32, both the two telescopic rods 311 can be contracted towards the direction of the groove 101 under the action of the spring force of the compression spring 312 (i.e. the elastic restoring force of the compression spring 312), so that the head ends of the two telescopic rods 311 are separated from the watch case 2, and the detachment operation with the watch case 2 is realized.

Preferably, the outer diameter of the head end of the telescopic rod 311 is matched with the inner diameter of the through hole 111, so that the telescopic rod 311 can be guided in a limiting manner through the through hole 111 to improve the stability of the telescopic motion of the telescopic rod 311 and ensure that the head end of the telescopic rod 311 can be reliably connected to the watch case 2 every time.

Moreover, the outer diameter of the end of the telescopic rod 311 is larger than the outer diameter of the compression spring 312, so that when the spring expansion assembly 31 is assembled in the groove 101, the compression spring 312 can be limited between the end of the telescopic rod 311 and the side wall (the side wall with the through hole 111) of the groove 101, so as to ensure that the compression spring 312 can be effectively pressed when the telescopic rod 311 moves towards the direction away from the groove 101, and the compression spring 312 is elastically deformed.

In practical applications, the angle between the two inclined surfaces 3321b of the sliding block 332 and the length direction of the watch band is preferably less than 45 °, so as to avoid the large resistance from affecting the pushing-out operation of the telescopic rod 311.

Preferably, the sliding block 332 further comprises an anti-slip part 3322 disposed on a side of the main body part 3321 away from the groove 101, so that a user can reliably drive the sliding block 332, and the difficulty of the dismounting operation is reduced.
