When a user needs to detach the watch band 10 from the watch body 20, the user only needs to press the top end of the key 14 to displace the bottom end of the key 14, so that the bottom end of the key 14 abuts against the second end of the clamping member 12, the second end of the clamping member 12 overcomes the elastic force of the elastic member 13, and rotates around the rotating shaft 121 in the second direction, so that the first clamping portion 122 and the second clamping portion 22 are disengaged from clamping; then, the second end of the watch main body 20 is pulled out of the insertion groove 21 of the watch main body 20, and the disassembly operation of the watch band 10 is completed; the whole disassembly process can realize the disassembly of the watchband 10 through pressing and pulling out operations, the disassembly process does not need to use a specific tool, and the operation is simple and convenient.

The watchband 10 of the utility model, the joint member 12 is rotatably connected with the band body 11 through the rotating shaft 121, which not only can ensure the reliable connection between the joint member 12 and the band body 11, but also can realize the joint or release joint between the watchband 10 and the watch main body 20 through the rotating motion of the second end of the joint member 12 around the rotating shaft 121, thereby realizing the assembly or disassembly of the watchband 10; by arranging the elastic piece 13, the first clamping part 122 at the second end of the watchband 10 is automatically clamped with the second clamping part 22 of the watch main body 20, and the clamping between the first clamping part and the second clamping part can be kept through elastic force; through setting up button 14, convenience of customers realizes the dismantlement of watchband 10 through pressing the operation, and is more convenient and fast.

Further, the clamping member 12 is rotatably connected to the belt body 11 through a rotating shaft 121, in this embodiment, the rotating shaft 121 is fixed to the clamping member 12.

In other embodiments, the rotating shaft 121 is also fixed to the belt body 11, in other embodiments, the rotating shaft 121 is separately disposed from the belt body 11 and the fastening member 12, and the rotating shaft 121 serves as a hinge shaft to hinge the belt body 11 and the fastening member 12.

Further, in order to facilitate the user to detach the watch band 10 by pressing the key 14, the top end of the key 14 passes through the mounting hole 113 and protrudes relative to the outer surface of the band body 11, and the bottom end of the key 14 is located in the mounting groove 111; the bottom end of the key 14 is used for pressing the clamping piece 12 when the top end of the key 14 is pressed by external force. With such an arrangement, the top end of the key 14 protrudes, so that a user can conveniently press the top end of the key 14 to perform an unlocking operation, so that the first clamping portion 122 and the second clamping portion 22 are released from clamping.

Further, the keys 14 are engaged with the clip 12 and the band 11 as follows:

the key 14 and the clamping piece 12 are arranged separately, the key 14 is movably connected with the belt body 11, and the key 14 has a degree of freedom of movement relative to the belt body 11; the key 14 is used for pressing the top end of the key 14 by external force, the bottom end of the key 14 moves, and abuts against the clamping piece 12 through the bottom end of the key 14 so as to drive the second end of the clamping piece 12 to rotate towards the second direction by overcoming the elastic force of the elastic piece 13.

Specifically, the key 14 and the clip 12 are separately arranged, that is, the key 14 has a state of contacting with the clip 12 and a state of being separated from the clip 12 and not contacting with the clip 12.

In this embodiment, the key 14 and the clip 12 are separately arranged, and for the scheme that the key 14 is connected to the clip 12, the contradiction that the clip 12 rotates to drive the key 14 to rotate and the mounting hole 113 limits the rotation of the key 14 can be solved, and the key 14 has a degree of freedom to move in the axial direction of the mounting hole 113, so that when the user presses the top end of the key 14, the key 14 moves in the direction close to the clip 12 until the bottom end of the key 14 abuts against the clip 12 and abuts against the clip 12, so that the second end of the clip 12 rotates around the shaft 121, and the watch band 10 and the watch body 20 are released from being clipped. With the arrangement, the size of the mounting hole 113 can be matched with that of the key 14, and excessive dust and impurities accumulated in the mounting groove 111 due to an overlarge gap between the mounting hole and the key can be avoided.

Further, on the basis that the belt body 11 is provided with the mounting hole 113 matched with the key 14, the key 14 is a step-type key 14; a step surface 141 is arranged between the top end and the bottom end of the key 14, the cross-sectional area of the step surface 141 is larger than that of the mounting hole 113, and the step surface 141 is used for preventing the bottom end of the key 14 from falling out of the mounting groove 111 through the mounting hole 113.
