[0051] A first micro switch 11 and a second micro switch 10 are also arranged inside the main mounting base 1 .

[0052] The beneficial effects of the above embodiments are as follows: the three-switch double-trigger self-resetting combination trigger for the aircraft control stick comprises a main mounting base, a main trigger and a secondary trigger respectively arranged on the first side and bottom surfaces of the main mounting base; the main trigger and the main mounting base are movably connected by a first straight-shaped threaded pin, so that the main trigger can be pulled and rotated relative to the main mounting base; the secondary trigger and the main mounting base are movably connected by a second straight-shaped threaded pin, so that the secondary trigger can be pulled and rotated relative to the main mounting base; a first microswitch and a second microswitch are also arranged inside the main mounting base to realize the trigger control of the aircraft simulator by the trigger combination trigger; the combination trigger realizes dual-signal operation by pressing the main trigger, and realizes single-signal operation by pressing the secondary trigger, and uses the secondary trigger as a backup, which effectively solves the problem of operating dual signals by pressing the trigger switch at one time, and the three switches of the combination trigger all have a self-resetting function, which improves the flexibility and reliability of the combination trigger operation and can improve the operating experience that is basically consistent with the real aircraft operation.

[0053] In another embodiment, a latch barrel 21 is disposed on the first side surface of the main mounting base 1, and a latch ring 22 is disposed at a position of the main trigger 5 corresponding to the latch barrel 21;

[0055] The beneficial effect of the above embodiment is that when the first slotted threaded pin 16 passes through the latch ring 22 and the latch tube 21 in sequence, the main trigger 5 can be rotatably set on the main mounting base 1. When the user pulls and presses the main trigger 5, the main trigger 5 can rotate around the rotation axis of the first slotted threaded pin 16 under the drive of the pulling and pressing action, and trigger the generation of corresponding dual signals during the rotation process.

[0056] In another embodiment, a mounting sheet 8 is further provided on the first side surface of the main mounting base 1; the inner side surface of the mounting sheet 8 is in contact with the first side surface of the main mounting base 1; and the outer side surface of the mounting sheet 8 is in contact with the spring sheet 9;

[0057] The mounting plate 8 and the spring plate 9 are fixedly connected to each other, and the impact end of the main trigger 5 contacts the spring plate 9; when the main trigger 5 is pulled and rotated, the impact end can rotate synchronously, thereby squeezing the spring plate 9.

[0058] The beneficial effects of the above embodiments are as follows: in order to enable the main trigger 5 to effectively generate corresponding dual signals under the action of the user's pulling and pressing, and to quickly restore to the original position when the user cancels the pulling and pressing action, the first side surface of the main mounting base 1 is sequentially provided with a mounting plate 8 and a spring plate 9, the spring plate 9 is attached to the mounting plate 8, and the impact end of the main trigger 5 is in contact with the spring plate 9. When the main trigger 5 is pulled and rotated, the impact end can rotate synchronously, thereby squeezing the spring plate 9 and generating corresponding dual signals in the process of squeezing the spring plate 9; when the user cancels the pulling and pressing action, the impact end of the main trigger 5 no longer squeezes the spring plate 9, and the generation of the dual signal stops at this time.

[0059] In another embodiment, the first side surface of the main mounting base 1, the mounting plate 8 and the spring plate 9 are correspondingly provided with a plurality of screw holes; the first pan head screw 20 passes through the screw holes corresponding to the spring plate 9, the mounting plate 8 and the first side surface of the main mounting base 1 in sequence, thereby fixing the mounting plate 8 and the spring plate 9 to the side surface of the main mounting base 1 in sequence.

[0060] The beneficial effect of the above embodiment is that in order to ensure that the mounting product 8 and the spring sheet 9 can be stably mounted on the first side surface of the main mounting base 1, the first pan head screw 20 is sequentially passed through the spring sheet 9, the mounting sheet 8 and the screw holes corresponding to the first side surface of the main mounting base 1, so that the mounting sheet 8 and the spring sheet 9 can be prevented from being separated from the main mounting base 1, thereby improving the structural stability of the combination trigger.

[0061] In another embodiment, a latch hole is provided on the second side surface of the main mounting base 1, and another latch hole is provided on the secondary trigger 4 at a position corresponding to the latch hole on the second side surface; the second straight-edge threaded pin 14 passes through the other latch hole and the latch hole, thereby movably connecting the secondary trigger 4 to the main mounting base 1; wherein the second side surface is perpendicular to the first side surface.

[0062] The beneficial effect of the above embodiment is that a pin hole is provided on the second side of the main mounting base 1, and another pin hole is provided on the secondary trigger 4 at a position corresponding to the pin hole on the second side, so that the second straight-threaded pin 14 movably connects the secondary trigger 4 to the main mounting base 1, so that the secondary trigger 4 can rotate relative to the main mounting base 1 with the second straight-threaded pin 14 as the rotation axis. In this way, the main trigger 5 and the secondary trigger 4 are respectively provided on the first side and the second side of the main mounting base 1, so that the user can independently control the main trigger 5 and the secondary trigger 4 from two directions, thereby realizing the double-pull operation of the combination trigger.

[0063] In another embodiment, a compression spring 13 is further provided between the secondary trigger 4 and the main mounting base 1; when the secondary trigger 4 is pulled and rotated relative to the main mounting base 1, the compression spring 13 is compressed; when the pulling force applied to the secondary trigger 4 is eliminated, the compression spring 13 recovers from the compressed state to the natural state, thereby driving the secondary trigger 4 to recover to its original position.

[0064] The beneficial effects of the above-mentioned embodiments are as follows: in order to enable the auxiliary trigger 4 to automatically be pulled, rotated and reset when the user applies and cancels the pulling and pressing operation, a compression spring 13 is also arranged between the auxiliary trigger 4 and the main mounting base 1. When the auxiliary trigger 4 is pulled and pressed by the user, the auxiliary trigger 4 can rotate, and at the same time the compression spring 13 is compressed and stores corresponding elastic potential energy; when the user cancels the pulling and pressing of the auxiliary trigger 4, the compression spring 13 recovers from the compressed state to the natural state, thereby driving the auxiliary trigger 4 to recover to its original position, thereby ensuring the automatic and rapid reset of the auxiliary trigger 4.

[0068] When the spring sheet 9 is squeezed by the impact end of the main trigger 5, the spring sheet 9 applies a rotational force to the other end of the spring pull rod 3, so that the spring pull rod 3 rotates relative to the main mounting base 1, and at the same time, one end of the spring pull rod 3 stretches the tension spring 15 during the rotation process;

[0069] When the squeezing effect of the impact end of the main trigger 5 on the spring sheet 9 is eliminated, the tension spring 15 recovers from the stretched state to the natural state, thereby driving the spring pull rod 3 to rotate and recover to the original position.

[0070] The beneficial effects of the above embodiment are as follows: the main mounting base 1 is further provided with a spring pull rod 3; the inner side of the second side surface of the main mounting base 1 is provided with a boss 22 and a tension spring fixing portion 23, the tension spring fixing portion 23 being located below the boss 22, and the spring pull rod 3 cooperates with the tension spring 15 to realize the lever action of the spring pull rod 3. When the spring sheet 9 is squeezed by the impact end of the main trigger 5, the spring sheet 9 will apply a rotational force to the other end of the spring pull rod 3, so that the spring pull rod 3 rotates relative to the main mounting base 1, and at the same time, one end of the spring pull rod 3 will stretch the tension spring 15 during the rotation process, so that when the main trigger 5 is pulled and pressed, the main trigger 5 controls the spring pull rod 3 through the spring sheet 9 as an intermediary. When the squeezing effect of the impact end of the main trigger 5 on the spring sheet 9 is eliminated, the tension spring 15 returns from the stretched state to the natural state, thereby driving the spring pull rod 3 to rotate and return to the original position, and quickly and stably realizing the reset of the spring pull rod 3.
