Further, it is additionally provided with stop column 621 at the position of the rotation direction making the disconnection of sound contact of former lever 71,
To be allowed to be rotated further along this rotation direction for withstanding former lever 71, in the present embodiment, stop column 621 is located at shell 62
Interior.
One end of push card 3 is provided with the second draw-in groove 31, and the head fits of described movable spring assembly 4 are in the second draw-in groove of push card
Place 31, described movable spring assembly 4 moves spring structure for closed type；In described second draw-in groove 31, for two side channels of push-and-pull movable spring assembly
Wall is set to the arc structure of middle protrusion.
In the present embodiment, movable spring assembly 4 is formed by stacking by three movable contact springs；In the head position of movable spring assembly, middle one
The width dimensions of piece movable contact spring are more than the width dimensions of other two panels movable contact spring, and the both sides of the width of middle a piece of movable contact spring are divided
It is not provided with the kink 41 of the 180 degree that bends inwards, the end of a piece of movable contact spring in the outer part is provided with the kink of through-thickness
42, for matching with the groove edge of the second draw-in groove 31 of push card.
Further, it is also equipped between motor 1 and gear reduction 2 for changing the angular wheel driving force direction
Transmission mechanism 8.
Described angular wheel transmission mechanism 8 includes the first angular wheel 81 and combined wheels 82, and described combined wheels are bored by second
Shape gear 821 and spur gear 822 are constituted, and described first angular wheel 81 is fixed in the rotating shaft of motor 1, the first angular wheel 81
