[0021] Example 1: like Figures 1 to 8As shown, this utility model provides a headstock structure 1, including a headstock body 11 and a spring ear assembly structure 12 disposed in the headstock body 11. The spring ear assembly structure 12 is used for inserting a spring ear assembly 2. The spring ear assembly 2 includes an unlocking operation end 21 and a locking end 22. The spring ear assembly 2 has a locked state and an unlocked state corresponding to the extension and retraction of the unlocking operation end 21 and the locking end 22, respectively. The spring ear assembly structure 12 includes a first cavity 121 and a second cavity 122 that are connected. The first cavity 121 is used to accommodate the locking end 22 of the spring ear assembly 2, and the second cavity 122 is used to accommodate the unlocking operation end 21 of the spring ear assembly 2. A fastening sleeve 13 is also provided in the first cavity 121, and a through hole 131 is provided in the fastening sleeve 13 for the locking end 22 to pass through.

[0022] In this invention, the spring ear assembly structure 12 is mainly applicable to the button-type spring ear assembly 2. The button-type spring ear assembly 2 can be directly inserted into the spring ear assembly structure 12 while maintaining its unlocked state, so as to realize the detachable connection between the spring ear assembly 2 and the headpiece body 11. The first cavity 121 and the second cavity 122 are connected to form the spring ear assembly structure 12 in the headpiece body 11, which greatly simplifies the assembly of the spring ear assembly 2 in the headpiece body 11, so that the button-type spring ear assembly 2 can be detachably connected to the headpiece body 11 as a modular structure, which is convenient for users to disassemble and replace the spring ear assembly 2. Secondly, the fastening sleeve 13 is provided in the first cavity 121. The fastening sleeve 13 has a through hole 131 extending along its axial direction. The locking end 22 of the spring ear assembly 2 is installed in the through hole 131. The fastening sleeve 13 is located between the spring ear assembly 2 and the headpiece body 11. The fastening sleeve 13 enhances the connection stability of the spring ear assembly 2 in the spring ear assembly structure 12.

[0023] In practical applications, such as Figure 1As shown, the unlocking operation end 21 can be configured as a button end. At least part of the button end can protrude through the second cavity 122 to the outside of the headpiece body 11, so as to facilitate the user to press and unlock the spring ear assembly 2. When unlocking, the unlocking operation end 21 can be extended and retracted along the second cavity 122 to drive the locking end 22 to extend and retract along the first cavity 121, so that the spring ear assembly 2 switches between the locked state and the unlocked state. When assembling, the unlocking operation end 21 drives the locking end 22 to retract into the first cavity 121, so that the spring ear assembly 2 switches to the unlocked state. At this time, the user can insert the spring ear assembly 2 into the first cavity 121 as a whole, and the spring ear assembly 2 moves into the first cavity 121 under external force. When the unlocking operation end 21 is pressed, the locking end 22 can be extended and retracted along the second cavity 122 to drive the locking end 22 to extend and retract along the first cavity 121 to switch the spring ear assembly 2 to the unlocked state. At this time, the user can insert the spring ear assembly 2 into the first cavity 121 as a whole, and the spring ear assembly 2 moves into the first cavity 121 under external force. When the device 21 moves to align with the second cavity 122, the unlocking operation end 21 can extend through the second cavity 122 to the outside of the headpiece body 11, so that the user can press to unlock the spring ear assembly 2. At the same time, the locking end 22 is driven by the unlocking operation end 21 to extend through at least one end of the first cavity 121 to the outside of the headpiece body 11, so as to realize the assembly of the spring ear assembly 2 in the headpiece body 11, and the headpiece structure 1 can be connected to the dial through the spring ear assembly 2. When disassembling, the user presses the unlocking operation end 21 to retract it into the second cavity 122, thereby driving the locking end 22 to retract into the first cavity 121. At this time, the unlocked state of the spring ear assembly 2 can be maintained and the spring ear assembly 2 can be pushed to the outside of the headpiece body 11 to realize the disassembly of the spring ear assembly 2.

[0024] Further optional, Figure 7 This is a schematic diagram showing the locked state of the spring ear assembly 2. Figure 8This is a schematic diagram of the unlocked state of the spring ear assembly 2. The spring ear assembly 2 also includes a spring ear shell 23 and a linkage structure 24 disposed between the unlocking operation end 21 and the locking end 22. The shape of the spring ear shell 23 is adapted to the spring ear assembly structure 12. The unlocking operation end 21 and the locking end 22 are respectively telescopically and movably mounted on the spring ear shell 23 through the linkage structure 24. When the unlocking operation end 21 is subjected to external force and telescopically moves relative to the spring ear shell 23, the linkage structure 24 can drive the locking end 22 to telescopically move relative to the spring ear shell 23, so that the spring ear assembly 2 switches between the locked state and the unlocked state. Optionally, the linkage structure 24 can be configured as a slanted push linkage structure 24 located between the unlocking operation end 21 and the locking end 22. The unlocking operation end 21 can drive the locking end 22 to retract into the first cavity 121 through the slanted push linkage structure 24 to realize the unlocked state of the spring ear assembly 2. Furthermore, the portion of the spring ear housing 23 corresponding to the locking end 22 is adapted to the through hole 131 of the fastening sleeve 13. The locking end 22 moves telescopically relative to the spring ear housing 23 and the fastening sleeve 13 to achieve telescopic movement of the locking end 22 relative to the inner and outer parts of the headpiece body 11 to switch between the locked and unlocked states.

At this time, an assembly gap adapted to the fastening sleeve 13 is formed between the headpiece body 11 and the locking end 22 of the spring ear assembly 2. This assembly gap is part of the first cavity 121. Subsequently, the spring ear assembly 2 can be... The fastening sleeve 13 is inserted into the assembly gap, and the locking end 22 passes through the through hole 131. The fastening sleeve 13 is installed between the headstock body 11 and the locking end 22, which enhances the installation stability of the spring ear assembly 2 in the headstock body 11, making the spring ear assembly 2 less likely to fall off and extending the overall service life of the headstock structure 1. In addition, when installing the spring ear assembly 2, the inner diameter of the first inner cavity is greater than the maximum height of the spring ear assembly 2 in the unlocked state.

[0030] Furthermore, as an optional embodiment of this solution, the headpiece body 11 is provided with a first connecting part 14 on the outer side. The first connecting part 14 can be used to connect components such as watch straps or lanyards to increase the application flexibility of the watch. Optionally, the headpiece body 11 can be connected to the watch strap through the first connecting part 14, and the headpiece body 11 can be connected to the dial through the spring bar assembly 2 to realize a detachable connection between the watch strap and the dial.

[0031] Further optional, such as Figure 1 As shown, the first connecting portion 14 extends radially outward from the outer edge of the headpiece body 11 along the first cavity 121, and an axial mounting hole 142 is provided in the first connecting portion 14. In this embodiment, the first connecting portion 14 can be used to connect woven watch straps, elastic watch straps, steel watch straps, or chain-link watch straps, etc., without specific limitation. The first connecting portion 14 protrudes outward from the headpiece body 11 to form an extension protrusion. The width of the extension protrusion is smaller than the width of the headpiece body 11. The through hole 131 is provided in the extension protrusion, and the through hole 131 can be set as a smooth hole or an internal threaded hole. The extension protrusion can be engaged with the watch strap through a concave-convex structure, and connected in the through hole 131 through a pin or threaded rod to connect the watch strap with the extension protrusion.
