Please refer to Figures 5A, 5B, 5C, 5D, 6A, 6B, 6C, 7A, and 7B. Figures 5A, 5B, and 6A show schematic views of the latch portion 1503 sliding on the circular slot 1102, and Figures 5C and 6B show the latch portions. A schematic diagram of 1503 sliding on the limiting groove 1472. Figures 5D and 6C show schematic views of the wide portion 1502 sliding on the sliding groove 1452. Figures 7A and 7B illustrate the movement of the latch portion 1503 along the circular slot 1102 and the limiting groove 1472, respectively. The movement trajectory and the corresponding angle, the operation instructions of the compensation mechanism 11 are as follows: After the sighting is completed, the compensation mechanism 11 is in a zero-setting position, as shown in Figures 5A, 5C and 5D At this time, the latch portion 1503 is located at a reference position 1105, and at the same time, a first end 1107 of the ring slot 1102 and a third end 1477 of the limiting groove 1472 are in contact with the latch portion 1503, and the wide portion 1502 is in contact with A fifth end 1507 connected to the sliding groove 1452, when performing spring compensation from the zero-set position, will restrict the adjustment cover 110 to only start to rotate in one of the clockwise direction or the counterclockwise direction. After the set position is reset to zero, the adjustment cover 110 is not limited to only being able to rotate in this direction. Turning the adjustment cover 110 allows the latch portion 1503 to move along the circumferential direction of the annular slot 1102 at the first end 1107 and a second end Between 1109. As shown in FIG. 7A, the latch portion 1503 moves along the annular slot 1102 from the first end 1107 to the second end 1109 by an arc L, and the center angle corresponding to the arc L is a first angle θ _L.

When the latch portion 1503 moves to contact the second end 1109 of the ring-shaped slot 1102, as shown in FIGS. 5B, 5C, and 5D, the adjustment cover 110 is rotated in this direction relative to the position set to zero. The first angle θ _L (less than one full circle), while the third end 1477 of the limiting groove 1472 still abuts the latch portion 1503, and the wide portion 1502 still abuts the fifth end 1507 of the sliding groove 1452, If the adjustment cover 110 is further rotated in this direction, the second end 1109 of the ring-shaped slot 1102 will be pushed against the latch portion 1503 and move between the third end 1477 and the fourth end 1479 along the circumferential direction of the limiting slot 1472. As shown in FIG. 7B, the latch portion 1503 is pushed against and moves along the limiting groove 1472 from the third end 1477 to the fourth end 1479 by an arc line K, and the center angle corresponding to the arc line K is a second angle θ _K.

Then, when the second end 1109 of the annular slot 1102 pushes against the latch portion 1503 along the circumferential direction of the limiting groove 1472 to abut against the fourth end 1479 of the limiting groove 1472, as shown in FIGS. 6A, 6B, and 6C As shown, the second end 1109 of the circular slot 1102 and the fourth end 1479 of the limiting slot 1472 abut the latch portion 1503, and the wide portion 1502 abuts a sixth end 1509 of the sliding slot 1452, adjusted at this time The cover 110 rotates the first angle θ _L plus the second angle θ _K (one full circle) in the direction relative to the zero-set position, and the adjustment cover 110 is therefore restricted from being able to continue to rotate in that direction , But the adjustment cover 110 can still be rotated in the opposite direction of this direction. The first angle θ _L and the second angle θ _K add up to 360 degrees, that is, the adjustment cover 110 rotates in this direction for one round and then stops immediately. In this embodiment, the direction is counterclockwise.

It is worth noting that to return the sight to the zero setting, it is only necessary to turn the adjustment cover 110 in the opposite direction of the direction until the first end 1107 of the ring-shaped slot 1102 and the second end 1477 of the limit slot 1472 are in contact When it is connected to the latch portion 1503 and cannot rotate, the compensation mechanism 11 returns to the zero-setting position.

In addition, when the adjustment cover 110 is restricted and can no longer rotate in this direction, to continue the spring compensation, the adjustment cover 110 can be pulled up to further compress the spring 125, and the adjustment cover 110 can be pulled up until the spring 125 It is completely compacted and stopped, so that the adjustment cover 110 and the connecting member 135 release the linkage relationship with the adjustment screw 120, and the latch portion 1503 also leaves from the ring slot 1102. At this time, turning the adjustment cover 110 does not drive the adjustment screw 120 Does not cause the latch portion 1503 to contact the first end 1107 or the second end 1109 of the annular slot 1102, and then rotate the adjustment cover 110 to position the latch portion 1503 relative to the first end 1107 of the annular slot 1102 After that, the adjustment cover 110 is released and the restoring force of the spring 125 is used to cause the adjustment cover 110, the connecting member 135, and the adjustment screw 120 to re-establish the interlocking relationship, and at the same time, the latch portion 1503 abuts the first end of the annular slot 1102 At 1107, the adjustment cover 110 is thus released from the restriction so as to continue the impact compensation.

The compensating mechanism of the aiming device of the present invention complements a ring-shaped slot on the inner side of the adjustment cover through a limit groove on the stop unit, which is not enough to rotate a full distance, and then cooperates with a latch portion on the stop unit, so that the compensation mechanism After adjusting one circle (360 degrees) in one of the clockwise or counterclockwise directions, it is immediately restricted and cannot be rotated. In use, the compensation mechanism can turn one circle (360 degrees) at a time, and the It can still continue to rotate after the limit. This design and operation are more intuitive for the user. It solves the problem that the user usually does not remember how many turns or angles have been turned when performing spring compensation. In addition, as long as the compensation The mechanism operates in the reverse direction until the compensation mechanism can no longer rotate, that is, returns to the zero-setting position, so the sight can also be easily returned to the zero-setting setting.
