Further, the height of the support column 112 is equal to the height of the lower case 12, so that when the upper case 11 and the lower case 12 are assembled, the gap between the upper cover 111 and the receiving space 121 is smaller, and the position of the upper case 11 and the lower case 12 after being clamped is more stable.

As shown in fig. 1 to 2, the supporting column 112 is formed with a notch 1120 corresponding to the contour of the slot 120. After the watchband 2 passes through the slot 120 of the lower case 12, the notch 1120 of the upper case 11, and the case core 3 in sequence, the watchband 2, the upper case 11, and the lower case 12 form a mortise-tenon structure, so that the upper case 11 and the lower case 12 are fixed to each other, and the case core 3 is contained in the containing space 121. Through mortise and tenon structure assembly wrist-watch, simple structure and installation convenient and fast more.

Further, the inner surface of the supporting column 112 is in an arc shape matching with the outer contour of the watch core 3, so as to limit the watch core 3 to be positioned in the quick-release watch case 1; and the arc-shaped inner surface can reduce the scratch of the watch core when the watch core is assembled, so that the surface of the watch core is scratched.

As shown in fig. 2, the case band 3 is formed with a bayonet 30 corresponding to the contour of the connecting portion of the band 2. After the watch core is assembled to the quick-release watchcase 1, the bayonet 30 is located inside the notch 1120 and corresponds to the clamping groove 120 in position and has a corresponding outline. In order to achieve quick assembly of the watch, the present utility model preferably forms a clip 21 on the watchband 2 matching with the bayonet 30, and the thickness of the clip 21 is equivalent to the height of the notch 1120 and the slot 120. As shown in fig. 4, the clamping strip 21 sequentially penetrates through the clamping groove 120 on the lower case 12, the bayonet 30 of the core 3 and the notch 1120 on the upper case 11 until two sides of the watchband 2 are coaxial with the quick-release case 11, so that a mortise and tenon structure is formed between the watchband 2 and the three to ensure the overall stability after installation; fig. 5 is a diagram showing the whole structure of the utility model after the installation.

Further, as shown in fig. 1 or fig. 2, the notch 1120, the slot 120, and the upper and lower surfaces 101 of the bayonet 30 all form inclined planes that incline toward the bottom of the lower case 12, and the inclined planes can guide the assembled watchband, and the inclined planes make the assembled wristwatch more ergonomic and increase the comfort after wearing.

As shown in fig. 2, the upper cover 111 is provided with a through hole 110 for exposing the dial in the middle, so that the user wears the watch and touches the dial. Of course, in other embodiments, a protective film with waterproof property can be designed at the through hole 110, and the protective film does not affect the dial of the user touch watch.

As shown in fig. 1 and fig. 3, the lower case 12 is centrally provided with a hollowed-out opening 123, the sensor on the watch core 3 is exposed from the hollowed-out opening 123, and the hollowed-out opening 123 has a symmetrical structure. The two sides of the lower watchcase 12 are respectively provided with a linkage key 31 and a knob 32 which are matched with and correspond to the watch core 3. The linkage key 31 includes a volume key, a through hole for driving the elastic piece in the watch core to extend out, and the knob 32 can be used for adjusting time. The watch can be physically operated by the linkage key 31 and the knob 32.
