It is connected to lower case 120.In this way, being conducive to improve each spinner subtracts bonding strength between upper housing 110, and improve each rotation
Bonding strength between slotware and lower case 120.
The utility model implementation in, the setting in a strip shape of spinner main body 1311, and the deposition path of spinner main body 1311 with
Connect the circular fitting of circle.
Further, referring to Fig. 6, each spinner main body is the first connected in the direction of extension.In this way, each spinner part 131 is made
It for an entirety, can be avoided that spin slot part is exposed, make the appearance coordinating and unifying of bottom case 100.
In the utility model implementation, spinner part 131 further includes being all connected to spinner main body 1311 towards the round heart of connection
Side the first locating part 1313 and the second locating part 1314, grab 1312 is located at the first locating part 1313 and the second locating part
Between 1314, wherein spin slot part is resisted against the first locating part 1313 towards grab when grab 1312 is located at and slides into section 1321b
1312 end, grab 1312 are located at buckle section when spin slot part is resisted against the second locating part 1314 towards the end of grab 1312
1321a。
In this way, in rotary course, when spin slot part is against to the first locating part 1313 towards the end of grab 1312, or
When against to the second locating part 1314 towards the end of grab 1312, user has pause and transition in rhythm or melody sense, and user can rapidly feel
Know the relative position between upper housing 110 and lower case 120.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modification, equivalent replacement or improvement etc., should be included in the guarantor of the utility model within novel spirit and principle
