Abstract: A stamping head includes a stamping portion and a connection portion connected to the stamping portion. The stamping portion includes a top surface and four side surfaces. The stamping head defines a jag extending from a junction between a specific one of the side surfaces and the top surface toward a centre of the top surface. The jag passes through the specific side surface. When the stamping head presses a ACF onto a ceramic substrate, a residual air between the ACF and the ceramic substrate flows outside through the jag.

Abstract: A transmission device for an exit device for a door includes a base (10) to which a transmission member (4) and a driving member (6) are pivotably mounted. A pushed section (611) of the driving member (6) abuts a push portion (421) of the transmission member (4). A link (7) is movably mounted to the base (10) and is connected to a latch of the exit device. When the transmission member (4) pivots from a first angular position to a second angular position, the push portion (421) of the transmission member (4) pushes the pushed section (611) of the driving member (6) to pivot the driving member (6) from a third angular position to a fourth angular position, and a push section (621) of the driving member (6) pushes a pushed portion (712) of the link (7) to move the link (7) for retracting the latch.

Abstract: A latch device for an exit device (1) includes a base (20) mounted to a side of a door. A first sliding member (30) is mounted to the base (20) and is movable relative to the base (20) between a first position and a second position. A stop (72) is mounted in a receiving portion (322) of the first sliding member (30) and is pivotable relative to the first sliding member (30) between first and second angular positions. A latch head (60) is mounted to the base (20) and is pivotable relative to the base (20) between a retracted position and in extended position. An abutment portion (725) of the stop (72) in the second angular position is located in a pivotal path of the latch head (60).
