Abstract: A trigger device is provided. The trigger device includes a controller, a screen assembly, an extendible support assembly operable to support the screen assembly, and a drive assembly operable to drive the support assembly. The drive assembly is provided with a first contact, and the support assembly is provided with a second contact movable relative to the second contact. During retraction or extension of the support assembly, the first contact and the second contact move relative to each other between a contacting state and a separating state. The controller determines whether the support assembly is in the retraction state or the extension state according to the contacting state or the separating state of the first contact and the second contact, so as to control display of the screen assembly. A smart bracelet is further provided.

Abstract: A support assembly includes a left support frame, a right support frame, and a bracket. The left support frame and the right support frame are both slidably connected to the bracket. The bracket defines receiving grooves. The left support frame includes a first tooth portion. The right support frame includes a second tooth portion. When the support assembly is in a folded state, teeth of the first tooth portion and teeth of the second tooth portion are received in the receiving grooves to support the screen assembly in a retracted state; when the support assembly is in an unfolded state, the teeth of the first tooth portion and the teeth of the second tooth portion extend out of the receiving grooves to support the screen assembly in an extension state. A dial plate and a smart bracelet are further provided.
