This invention relates to the field of composite bow technology, specifically to a rotary composite bow stop block. The stop block is rotatably mounted and cylindrical. Its surface has an annular groove for constraining the bowstring. When the bowstring collides with the stop block, a cutting action also occurs between the bowstring and the stop block.

This reduces the reaction force of the stop block on the bowstring, thus promoting stability of the magnetic base and improving shooting accuracy. Furthermore, the constraint of the bowstring by the annular groove further enhances the accuracy of steel ball firing.

This invention discloses a pneumatic ejector pin for a semi-automatic long-range injection device, comprising an outer cylinder and an inner cylinder slidably mounted therein. The front section of the inner cylinder can protrude from the front end of the outer cylinder under the push of rear gas. A pressure switch is built into the inner cylinder; when the inner cylinder is in the protruding state, the pressure switch can be opened by the rear gas, allowing the rear gas to pass forward through the inner cylinder. By setting the inner cylinder, under the push of the rear gas, the inner cylinder can protrude forward from the outer cylinder, pushing the injection needle located inside the barrel forward and disengaging it from the area directly opposite the magazine. This allows the injection needle inside the barrel to escape the pressure of the injection needle or elastic base plate below. Since the injection needle inside the barrel has already separated from the injection needle or elastic base plate below before being pushed out by the rear gas, no additional friction is generated, thus avoiding the range and circuit effects caused by friction, and thereby improving shooting accuracy.

This invention establishes a particle image processing workflow that can rapidly process large numbers of image samples, effectively achieving high-speed and high-precision measurement of micron-sized particle size during impact with a wall compared to traditional particle shadow velocimetry.
