[0045] Specifically, under normal circumstances, the buckle 21 and the fastening buckle 22 are respectively engaged with the bayonet 101 and the movable opening 102, and the driving member 32 drives the lock head 31 to engage the fastening buckle 22, so as to fix the cover 2 on the shell 1 and enclose the accommodating cavity 10; when disassembling, the driving member 32 drives the lock head 31 to disengage from the fastening buckle 22, and then the cover 2 is pried to make the buckle 21 and the fastening buckle 22 disengage from the bayonet 101 and the movable opening 102 respectively, so that the cover 2 can be removed from the shell 1 and the accommodating cavity 10 is exposed, so that the user can take and put the watch P.

[0046] During assembly, the buckle 21 is engaged with the buckle 21, and then the cover plate 2 is swung so that the fastening buckle 22 is inserted into the movable opening 102, and then the lock head 31 is driven by the driving member 32 to enter the movable opening 102 and engage the fastening buckle 22, so that the cover plate 2 can be fixed on the shell 1 and the accommodating cavity 10 is closed.

[0047] In summary, the utility model limits the first side of the cover plate 2 by the matching design of the buckle 21 and the bayonet 101, and limits the second side of the cover plate 2 by the matching design of the fastening buckle 22 and the lock head 31, so as to achieve the installation of the cover plate 2; by designing the driving member 32 to drive the lock head 31 to engage with or disengage from the fastening buckle 22, so as to facilitate the release of the restriction on the second side of the cover plate 2, and because the fastening buckle 22 can enter and exit the movable opening 102, the buckle 21 can be disengaged from the bayonet 101, thereby facilitating the release of the restriction on the first side of the cover plate 2 and achieving the disassembly of the cover plate 2; compared with the existing fixing method, the present solution is not only simple in structure, but also more convenient to disassemble and assemble, which can effectively improve the user experience.

[0048] See attached Figure 10 -Attached Figure 16, there are various types of driving members 32. For example, electric members with a moving stroke such as a micro cylinder or a micro lead screw motor (not shown in the figure) can be used to improve the degree of automation; a manual member can also be used, and the present utility model does not limit this; for the convenience of understanding, in this embodiment, a manual member is taken as an example; a chute 104 communicating with the outside is opened on the side wall of the guide groove 103, and the chute 104 is consistent with the length direction of the guide groove 103; the driving member 32 is a dial rod 320, the dial rod 320 is movably arranged in the chute 104, and the tail end of the dial rod 320 extends into the guide groove 103 and is fixedly connected to the lock head 31, and the head end of the dial rod 320 extends to the outside. Pushing the head end of the dial rod 320 can drive the lock head 31 to enter and exit the movable port 102.

[0049] Specifically, under normal circumstances, the lock head 31 is located in the movable port 102 and is clamped to the fastening buckle 22 to lock and fix the cover plate 2; pushing the head end of the dial rod 320 drives the lock head 31 to move out of the movable port 102, so that the lock head 31 is disengaged from the fastening buckle 22, and the cover plate 2 can be loosened for the user to disassemble; compared with using a motor member, using a manual member can not only save costs, but also facilitate the user to directly operate.

[0050] Refer to the appendix Figure 4 - appendix Figure 11 , during the use process, in order to prevent the lock head 31 from moving by itself and disengaging from the fastening buckle 22, the lock head 31 and the guide groove 103 can be designed to be in an interference fit, or the dial rod 320 and the chute 104 can be designed to be in an interference fit, so as to have damping between the lock head 31 and the housing 1. However, considering that the operation feel is not good and it is still easy to loosen after long-term use, the locking part 3 in the present utility model further includes an elastic member 33, and the elastic member 33 is arranged in the guide groove 103 and abuts against the lock head 31 and the side wall of the guide groove 103.

[0051] Specifically, when the lock head 31 is located in the movable port 102 and is clamped to the fastening buckle 22, the elastic member 33 is in a normal state, and under the action of elastic potential energy, the lock head 31 keeps clamping the fastening buckle 22; when the lock head 31 is moved out of the movable port 102 and the fastening buckle 22, the elastic member 33 stores energy and compresses; at this time, if the dial rod 320 is released, the elastic member 33 releases energy and restores, driving the lock head 31 to reset to clamp the fastening buckle 22, and the operation feel is good.

[0052] Furthermore, the elastic member 33 can be a component with deformation and recovery ability such as a rubber sleeve or a spring. For the convenience of understanding, the elastic member 33 in this embodiment is a spring; and to prevent the spring from falling off, a fixing shaft 310 for inserting the spring is further provided at one end of the lock head 31 away from the fastening buckle 22.
