When the slide plate 34 is slid to the position where the protrusion 341 is engaged with one of the recesses 312, the slide plate 34 just triggers the first gear switch 331, and when the slide plate 34 is slid to the position where the protrusion 341 is engaged with the other recess 312, the slide plate 34 just triggers the second gear switch 332. In this way, the triggering position of the slide plate 34 can be positioned, the slide plate 34 is prevented from being in poor contact with the first gear switch 331 and the second gear switch 332, and the user can be provided with a feeling of engagement, so as to prompt the user whether the triggering position of the slide plate 34 is in place. That is to say, the number of the recesses 312 can be two. In this case, when the protrusion 341 is engaged with the recess 312, it indicates that the first gear switch 331 or the second gear switch 332 is triggered, and when the protrusion 341 is not engaged with the recess 312, it indicates that the first gear switch 331 and the second gear switch 332 are not triggered. In other embodiments, the number of the protrusions 341 can also be three. When the protrusion 341 is engaged with one of the recesses 312, it indicates that the first gear switch 331 and the second gear switch 332 are not triggered by the slide plate 34. In this way, the slide plate 34 can be fixed so as not to be easily slid.
[0044] Of course, in other embodiments, the protrusions 341 can be provided on the seat body 31, and the recesses 312 can be provided on the slide plate 34, which is not limited herein.
