Manual releaser capable of being remotely and safely operated

The invention discloses a manual releaser capable of being remotely and safety operated. According to the manual releaser, a body, a gripper arm, a pull rod and an actuating rod are sequentially hinged to one another to form a four- rod mechanism. Four hinge shafts of the four-rod mechanism are arranged to be an A shaft, a B shaft, a C shaft and a D shaft in sequence. When the A shaft, the C shaftand the D shaft are collinear and the four-rod mechanism is locked by itself, the gripper arm is pressed on the body, and the gripper arm and/or the body are/is provided with a jaw. The manual releaser is used for solving the problems that an existing releasing mechanism is poor in environment adaptability, complex to operate and low in reliability. 一种可远程安全操作手动释放器，包括由主体、钳爪、拉杆和动作杆依次铰接成四杆机构，将四杆机构四个铰轴依次设为A轴、B轴、C轴和D轴，在A轴、C轴和D轴共线、四杆机构自锁时，钳爪压紧在主体上，在钳爪和/或主体上开设有钳口。本发明用于解决现有释放机构环境适应性差、操作繁琐，可靠性低的问题。
