Abstract: A flushing switch device with automatic pressing stroke detection is provided, which is applied to the flushing switches of a toilet. The flushing switch device with automatic pressing stroke detection includes a capacitive sensor, an actuator, and a protector. The capacitive sensor senses a user's hand movements to generate a sensing signal. The actuator includes a driver and a pressing mechanism; the driver drives the pressing mechanism to press one of the flushing switches. The protector includes a detector and a controller; the detector detects a load variation during an operation of the actuator to generate a detection signal; the controller receives the sensing signal and correspondingly generates a control signal to control the actuator according to the sensing signal and the detection signal.

Abstract: A luggage truck includes a base frame fixedly fastened to a luggage body at the bottom, two parallel sleeves respectively pivoted to the base frame and joined by a transverse connecting bar, two sliding tubes respectively sliding in the sleeves and joined by a handle grip outside the sleeves, and two sliding coupling devices moved on the sleeves and coupled to a locating frame at the rear side of the luggage body, each sliding coupling device including a sliding block mounted around one sleeve, a connector having a first coupling tube coupled to the sliding block and a second coupling tube extended from the first coupling tube at right angles, a first link having a hooked bottom end inserted into a through hole in the sliding block and hooked on the first coupling tube of the connector and a top end coupled to the handle grip, and a second link having one end pivoted to the locating frame of said luggage body and an opposite end connected to the second coupling tube of the connector.
