In addition, it is worth noting that a recessed hole 153 is also provided in the body 151, and the recessed hole 153 is connected to the channel 154. When the moving element 141 enters the recessed hole 153, the rotation of the adjustment cover 11 can be restricted and stopped at a first step. One zero o'clock position.

Before operating the aiming correction mechanism 10 for ball impact compensation, a zero setting must be performed first, and the aiming correction mechanism 10 of the present invention needs to set a total of two zero-point positions, which are a first zero-point position and a second zero-point position. It is assumed that the first zero point position corresponds to a reference shooting distance (for example, the bullet impact point is at 100 yards, but the present invention is not limited to this distance), and the second zero point position corresponds to a shorter shooting distance (for example, after installing a silencer, the bullet impact point is The original 100 codes are reduced to 75 codes, but the present invention is not limited to this). First, the user removes the adjustment cover 11 and manually rotates the moving element 141 so that the moving element 141 drops to the lowest position and contacts the contact plate 142, and then performs zeroing shooting (the target is placed at a distance of 100 yards). , according to the shooting result, rotate the rotating cylinder upper cover 121 to adjust the position of the adjusting element 19 to complete the first zero point setting. Then, continue to rotate the rotating cylinder upper cover 121 according to the preset rotation amplitude (the rotation amplitude is calculated in advance based on the difference between the reference shooting distance and the shorter shooting distance), for example, 9 clicks (but the invention is not limited to this) , that is, the second zero point setting is completed. Next, the user rotates the moving element 141 so that the moving element 141 moves axially relative to the contact plate 142 toward the sleeve upper cover 131 until the flange portion 144 contacts the lower end of the sleeve upper cover 131 and stops. At this time, the moving element 141 at the highest point to ensure that the moving element 141 can enter the groove body 112 when the adjustment cover 11 is replaced. Then, the user can reinstall the adjustment cover 11. When reinstalling, the end 113 of the groove body 112 must be aligned with the moving element 141, so that the moving element 141 can just abut against the stopper 115. Finally, the user uses the adjustment cover fixing member 311 to fix the adjustment cover 11 and the transmission unit 12 together to complete the zero setting.

At this time, the user needs to press the locking unit 15 to release the adjustment cover 11 (Figure 5), and then can rotate and adjust. The cover 11 performs bounce compensation. Specifically, the user presses the locking unit 15 to make the moving element 141 leave the recessed hole 153 (Fig. 5), and then the user rotates the adjustment cover 11 in the second direction D1 to make the moving element 141 enter the channel 154 (Fig. 6 ), the user continues to rotate the adjustment cover 11, which will cause the moving element 141 to leave the channel 154 and the locking unit 15 to pop up under the action of the elastic member 152 (Fig. 7). The user can continue to rotate the adjustment cover 11 in the second direction D1. Bounce compensation (Picture 8). On the other hand, the rotation of the adjustment cover 11 will simultaneously drive the transmission unit 12 to rotate relative to the base unit 13, thereby driving the adjustment element 19 to move axially relative to the base unit 13. During the rotation process, the transmission unit 12 moves The element 141 and the contact plate 142 will move axially relative to the base unit 13 in a direction away from the sleeve upper cover 131. It is worth noting that the moving element 141 has left the groove 112 before the adjustment cover 11 rotates for one revolution. , at this time, the moving element 141 will not be blocked by the stopper 115, so that the user can continue to rotate the adjustment cover 11 in the second direction D1 to compensate for the bounce.

During the above-mentioned ball impact compensation process, the user can return the aiming correction mechanism 10 to the first zero position at any time. Specifically, the user can rotate the adjustment cover 11 in the third direction D2 (opposite to the second direction) to drive the transmission unit 12 to rotate, thereby causing the adjustment element 19 to move axially. During the rotation of the transmission unit 12, The moving element 141 and the contact plate 142 will move axially relative to the base unit 13 in a direction close to the sleeve upper cover 131 , and then the moving element 141 enters the groove body 112 and returns to the recessed hole 153 through the channel 154 of the locking unit 15 , at this time the locking unit 15 pops up to lock the adjustment cover (Fig. 4).

If the user wants to rotate the aiming correction mechanism 10 to the second zero position, then As long as the locking unit 15 is pressed, the moving element 141 leaves the recessed hole 153 (Fig. 5), and then the user rotates the adjusting cover 11 toward the third direction D2 (Fig. 9) until the moving element 141 reaches the end 113 of the groove 112 Until it resists the stopper 115, the adjustment cover 11 is at the second zero position and cannot continue to rotate in the third direction D2, and the flange portion 144 is in contact with the lower end of the sleeve upper cover 131 and the moving element 141 Rise to the highest point.

By cooperating with the locking unit 15 and the movement of the moving unit 14, the present invention can provide two zero-point positions, allowing the user to flexibly use them as needed, making the operation more convenient.
