Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

A watchband capable of being assembled and disassembled quickly is shown in figures 1 and 2 and comprises two band bodies 1 which are respectively positioned at two sides of a watch shell, and connecting structures are arranged at the end parts of the two band bodies 1 and are used for connecting the band bodies 1 with the watch shell (not shown in the figure).

As shown in fig. 3 and 4, the connection structure includes a connection shell 2 disposed at an end of the band body 1 and being hollow, an elastic member 3 disposed inside the connection shell 2, two sliders 4 disposed at two ends of the elastic member 3, insertion holes 5 disposed at two sides of the connection shell 2 and communicated with an inner cavity thereof, a needle 6 disposed on the sliders 4 and partially disposed outside the connection shell 2 through the insertion holes 5, and a button 7 for driving the two sliders 4 to move in opposite directions.

The elastic member 3 in the present invention is preferably a return spring.

The specific working principle is as follows: when the area body takes off from watch shell as required, the user only needs to utilize button 7, make two sliders 4 remove in opposite directions and elastic component 3 take place the compression, make syringe needle 6 from the state that the part is located connecting shell 2 outside, move to the state that is located connecting shell 2 completely, retract syringe needle 6 into connecting shell 2 in, thereby let syringe needle 6 deviate from the ear of watch shell both sides, compare with prior art, can make the user only need simple operation just can separate area body and watch shell easily.

The connecting shell 2 is provided with an accommodating groove 8 for accommodating the key 7, one side of each of the two sliding blocks 4 close to the accommodating groove 8 is provided with a pressing groove 9, the groove wall of each pressing groove 9 close to one side of the elastic piece 3 is provided with a first inclined surface 10, and two ends of the key 7 respectively abut against the first inclined surfaces 10 of the two sliding blocks 4; when the key 7 is pressed down, the two ends of the key 7 drive the two sliders 4 to move relatively through the two first inclined surfaces 10.

When a user presses the key 7, the two ends of the key 7 respectively apply a force perpendicular to the first inclined surfaces 10 of the two sliders 4 to the first inclined surfaces 10, and a partial component of the force is directed to the elastic member 3, so that the elastic member 3 contracts, and the function of moving the two sliders 4 in the opposite direction is achieved.

Two ends of the key 7 are respectively provided with a second inclined surface 11 parallel to the first inclined surface 10; the line contact of the key 7 and the first inclined plane 10 is converted into surface contact, the contact area is increased, the local pressure intensity is reduced, the key 7 can apply force to the sliding block 4 uniformly, and the situation that deformation is caused by the fact that local stress is too large is prevented.

The two ends of the key 7 are respectively provided with a protruding part 12 for limiting the key 7 in the inner cavities of the accommodating groove 8 and the connecting shell 2 and preventing the key 7 from falling out of the accommodating groove 8.

When the elastic element 3 is in a natural state, the length of the needle 6 extending out of the connecting shell 2 is 0.75 mm; the effective length of the lugs which can fix the connecting shell 2 on the two sides of the watch shell is more than 0.5mm, and 0.75mm is the most appropriate size of the combination shape.

One side of each of the two sliders 4 close to the elastic member 3 is provided with a groove 13, and two end portions of the elastic member 3 are respectively positioned in the grooves 13 of the two sliders 4, so that the function of fixing the elastic member 3 is achieved.

As shown in fig. 5, the connecting shell 2 is provided with a first pinhole 14, the end of the belt body 1 is inserted into the connecting shell 2 and is provided with a second pinhole 15 aligned with the first pinhole 14, and PIN needles 16 are inserted into the first pinhole 14 and the second pinhole 15; the PIN 16 is used to simultaneously penetrate through the first pinhole 14 and the second pinhole 15 so as to fix the belt body 1 and the connecting shell 2 more stably.

A stop block 17 is arranged in the connecting shell 2, and the stop block 17 is positioned between the end part of the belt body 1 and the slide block 4; the stopper 17 is used to separate the end of the belt body 1 from the slider 4, avoiding the two structures from affecting each other.

The connecting shell 2, the key 7 and the sliding block 4 are all made of stainless steel or aluminum materials; stainless steel has good deformation-preventing property, while aluminum has good light and thin property, which has both advantages and disadvantages.

The included angle between the first inclined surface 10 and the bottom groove wall of the pressure groove 9 is 155 degrees; according to the length of the needle 6 extending out of the connecting shell 2, an included angle of 155 degrees is selected, so that the pressing stroke of the key 7 can be controlled between 0.35mm and 0.4mm, which is the optimal pressing stroke.

In addition, the embodiment also provides a watch, which comprises a watch shell and a watchband, wherein the watchband is the watchband.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments.
