Description

Technical Field

[0001] The utility model relates to the technical field of operating rods, in particular to an operating rod locking and fixing tool. Background Art

[0002] The joystick is a device that is pushed (pulled) laterally to control the ailerons. When an airplane takes off, it cannot fly relying solely on speed; a timely upward lifting force is also required. The forward and backward movement of the joystick adjusts the angle of the horizontal tail, so a joystick is used to control the rise and fall of the aircraft.

[0003] For example, the Chinese patent number CN206813299U is a joystick position locking device for an aircraft and an aircraft. The utility model device includes a fixed seat and a detachable locking mechanism. The fixed seat is fixedly arranged in the aircraft. The detachable locking mechanism is connected to the fixed seat. The detachable locking mechanism has a locked state and a free state. The joystick of the aircraft is connected to the fixed seat through the detachable locking mechanism in the locked state, and the detachable locking mechanism in the locked state can lock the joystick in a predetermined position. When the detachable locking mechanism is in the free state, the detachable locking mechanism is disengaged from the joystick, and the joystick is in the free state. The utility model allows the joystick of the aircraft to be in a locked state, avoids the instability of the joystick, and improves safety. However, during use, the device only uses a connecting rope to fix the locking plate, and the stabilization effect is not good. Long-term use will cause the connecting rope to break, thereby shortening the service life of the locking device. At the same time, it only relies on the locking piece for fixing, and the locking effect is poor. Therefore, a joystick locking and fixing tool is proposed to solve the above-mentioned problems.
