摘要： The present invention provides a device for releasing a locked trigger set by a set-trigger mechanism widely applied to a gun such as a rifle which comprises at least a receiver, a bolt loosely inserted in the receiver, and a bolt handle for rotating and reciprocating the bolt so as to load a bullet and set in a fire-enabling state, wherein the locked trigger releasing device comprises: an abutting portion formed on the bolt handle, and a release means having a release link and capable of being brought into contact with the abutting portion and pushed down toward a trigger in accordance with a rotational movement of the bolt handle, whereby the trigger locked by the set-trigger mechanism is released when the bolt handle is rotated up to a fire-disabling position, at which the abutting portion is abutted with the release means thereby to urge the release means to push the trigger to unlock it.
With this construction above, only when the bolt handle is rotated up to the fire-disabling position at which the abutting portion formed thereon abuts with the release means so as to release the locked trigger, the loading/removal of a bullet into/out of a barrel cartridge chamber is enabled by way of the receiver. In other words, when the bolt handle is in the fire-disabling state, the trigger can never be in the locked position, which enables a safe and secure release of the locked trigger.摘要翻译： 本发明提供了一种用于释放由广泛应用于诸如步枪的枪的集触发机构设置的锁定触发装置，该装置包括至少一个接收器，松动地插入接收器中的螺栓和用于旋转和往复运动的螺栓手柄 所述螺栓以装载子弹并设置在起火状态，其中所述锁定扳机释放装置包括：形成在所述螺栓手柄上的抵接部分，以及具有释放连杆并且能够与 抵靠部分并且根据螺栓手柄的旋转运动而朝向触发器向下推动，由此当螺栓手柄旋转到禁火位置时，由触发器机构锁定的触发器被释放， 部分与释放装置抵接，从而促使释放装置推动触发器将其解锁。 利用这种结构，只有当螺栓把手旋转到其上形成的邻接部分的防火位置与释放装置抵接以释放锁定的触发器时，将子弹装载/移出 通过接收器启用桶式暗盒。 换句话说，当螺栓手柄处于灭火状态时，触发器永远不会处于锁定位置，这样可以安全和可靠地释放锁定的触发器。
