The inside in portion 13.Wherein, the actuator 2 at it is elongated and include positioned at opposite end a fixing end 21 (such as: in Fig. 2
2 top of actuator) and driving end 22 (such as: 2 bottom end of actuator in Fig. 2), and above-mentioned fixing end 21 is connected in described
The base portion 111 of frame 11, and the driving end 22 is connected to above-mentioned displacement input unit 12 (drive block 121).
Accordingly, when the actuator 2 forces in the displacement input unit 12 of the displacement amplifier 1, the displacement input
Linearly L moves first distance and multiple enlargers 14 is forced to rotate in portion 12, so that the force of multiple enlargers 14
142 rotation of point, and then the displacement output section 15 linearly mobile second distance of L is driven jointly.
As shown in Figure 1 to Figure 3, the outer framework 3 for rectangular frame and is formed with a perforation 31 in this present embodiment, to
Accommodate a part 200 (such as: the striker in dispenser system) to be triggered.Wherein, the displacement amplifier 1 is located at described with actuator 2
In outer framework 3, the inner frame 11 (base portion 111) is fixed on outer framework 3, between the displacement output section 15 and outer framework 3
There are the third distances for being greater than the second distance, and the displacement output section 15 (triggering block 151) is worn towards described
Hole 31.
Furthermore when the actuator 2 forces in the displacement input unit 12 of the displacement amplifier 1, the displacement output
Portion 15 (triggering block 151) linearly L and mobile towards 31 sides of perforation and contact is in the part 200 to be triggered, so as to
Trigger member 200 can be moved along rectilinear direction L.
