As the angle between the bracket 1 905 and the bidirectional screw 902 increases, the angle between the bracket 2 906 connected to the support plate 907 and the support plate 907 is gradually increased under the drive of the bracket 1 905, thereby increasing the distance between the support plate 1 and the support plate 907, so that the height of the support cushion 2 is continuously increased, so that the boar can lie on the support cushion 2 in a more suitable posture); Step 2: guide the boar to lie on the support cushion 2 and place its forelimbs on the forelimb support board 3, guide the boar to perform reproductive behavior on the silicone sleeve 6 on the isolation tube 5, and use the massage stimulation module 8 to increase the stimulation of the boar so that the boar can accelerate the process of ejaculation, and use the collection bottle 7 to collect the semen of the boar (guide the boar to lie on the support cushion 2 and place its forelimbs on the forelimb support board 3, guide the boar to perform reproductive behavior on the silicone sleeve 6 on the isolation tube 5, start the motor 1 812, the motor 1 812 drives the gear 2 813 to mesh and rotate with the outer gear ring 811, so that the inner gear ring 1 808 connected to the outer gear ring 811 drives the short shaft 809 to rotate, so that the arc panel 816 on the gear 3 814 drives the mounting plate 81 7 rotates with the silicone sleeve 6 as the axis. During the rotation, the gear four 821 meshes and rotates with the massage convex ring 815, so that the transmission rod 825 on the gear four 821 pushes the sliding member 826 to reciprocate with the rotation of the transmission rod 825, so that the pressing rod 827 connected to the sliding member 826 can press the silicone sleeve 6. With the continuous pressing of the pressing rod 827, the massage convex ring 815 on the inner wall of the silicone sleeve 6 stimulates the boar's genitals. The boar's semen will be collected by the collecting bucket 802 and transported into the collecting bottle 7 in the protective frame 804 through the conveying pipe 803.
