Fig. 10A-10D show schematic views of the attachment of strap 120 to bottom shell 110.

As shown in fig. 10A, the connector 204 of the strap 120 has not yet entered the mounting slot 112, and the key 140 is in the first position.

As shown in fig. 10B and fig. 10C, the binding band 120 is pushed into the mounting groove 112 toward the connector 204, due to the guiding effect of the first guiding cambered surface 412 and the second guiding cambered surface 606, the two arms 408 of the limiting portion 406 of the key 140 are respectively pressed by the beams 602 of the two clamping joints 206, the limiting portion 406 is retracted into the accommodating groove 116 against the elastic force of the elastic member 150, the moving direction of the limiting portion 406 is perpendicular to the pushing direction of the connector 204, and the limiting portion 406 drives the whole key 140 to gradually switch from the first position to the second position. As shown in fig. 10D, when the beam 602 of the card connector 206 completely passes through the arm 408 of the key 140, the arm 408 of the key 140 loses the pressing force of the beam 602, the elastic member 150 provides an elastic force to quickly reset the key 140 (restore from the second position to the first position), and the arm 408 of the key 140 enters the limit slot 604 of the card connector 206 to lock the arm 408 in the limit slot 604 of the card connector 206, where the second mating surface 605 of the beam 602 is opposite to the first mating surface 410 of the arm 408. And when strap 120 is forced in the opposite direction to mounting slot 112, second mating surface 605 of beam 602 will abut first mating surface 410 of arm 408, and connector 204 of strap 120 cannot be pulled out of mounting slot 112, so that connector 204 of strap 120 is firmly secured in mounting slot 112. Therefore, when the binding belt 120 is installed, the connector 204 of the binding belt 120 is only required to be directly inserted into the installation groove 112, so that the clamping connection can be realized, and the convenience and the rapidness are realized.

When the strap 120 needs to be separated from the bottom case 110, an external force is applied to the pressing portion 402 of the key 140, the external force is greater than the elastic force provided by the elastic member 150, and the key 140 moves from the first position to the second position, at this time, the pressing portion 402 of the key 140 is sunk into the key hole 114 due to the external force, the surface of the pressing portion 402 is not exposed to the bottom wall of the bottom case 110, the supporting arm 408 of the key 140 is separated from the limit groove 604 of the clamping head 206, the whole limit portion 406 is sunk into the accommodating groove 116 and is not exposed to the mounting groove 112, so that the limit portion 406 is separated from the connecting head 204 of the strap 120, and the strap 120 can be pulled out from the bottom case 110. Thus, the position of the key 140 can be changed by the elastic force of the elastic member 150 and the external force acting on the pressing portion 402 of the key 140, so that the strap 120 can be quickly replaced. Those skilled in the art will appreciate that the first guide curve 412 of the arm 408 and the second guide curve 606 of the catch 206 are not required. In some embodiments, the first guide curve 412 may not be provided on the arm 408 and the second guide curve 606 may not be provided on the bayonet 206. When the binding band 120 is installed, since the guiding action of the first guiding cambered surface 412 and the second guiding cambered surface 606 is not provided, the key 140 needs to be pressed down first, so that the limiting part 406 is sunk into the accommodating groove 116 and is not exposed in the installation groove 112, and after the connector 204 of the binding band 120 is inserted into the installation groove 112, the key 140 is released, so that the connector 204 of the binding band 120 is clamped with the limiting part 406 of the key 140. In this embodiment, the key 140 is pressed when the strap 120 is installed, and the strap 120 is removed in the same manner, which is also convenient and quick when the wristband is removed, as opposed to the case where the arm 408 has the first guide curve 412 and the clasp 206 has the second guide curve 606.

As shown in fig. 6, the key 140 further includes a guiding rib 416 disposed on the connecting portion 404 and the limiting portion 406, and referring to fig. 5, a guiding groove 162 corresponding to the guiding rib 416 is formed in the accommodating groove 116. The guide ribs 416 and the guide grooves 162 are parallel to the key hole 114 and perpendicular to the plane of the notch of the receiving groove 116. The pressing portion 402 of the key 140 can be moved in the guide direction when an external force is applied thereto by the engagement of the guide rib 416 and the guide groove 162. A step 418 is formed between the guide rib 416 and the connecting portion 404, the step 418 being configured to abut the groove wall of the mounting groove 112 adjacent the key hole 114. The step 418 is used to limit the travel of the key 140, and prevent the connection portion 404 of the key 140 from entering the key hole 114 under the action of the elastic member 150.
