[0033] The using process of the tennis bracelet production device provided by the present invention is as follows: The tennis bracelet accessories are added into the vibrating bowl 4. The vibrating bowl 4 is used to arrange the tennis bracelet accessories in a preset direction, so that the tennis bracelet accessories are sorted and conveyed into the first feeding guide rail 401 by the vibrating bowl 4. The tennis bracelet accessories are arranged side by side in the first feeding guide rail 401 instead of end to end. When the tennis bracelet accessories in the first feeding guide rail 401 reach the connection between the first feeding guide rail 401 and the second feeding guide rail 6, the first air cylinder 702 pushes the lifting plate 703 to rise, and the tennis bracelet accessories are pushed to rise through the lifting plate 703 so as to align them with the second feeding guide rail 6. The second linear module 502 drives the pushing plate 503 to move, and the tennis bracelet accessories reaching the connection between the first feeding guide rail 401 and the second feeding guide rail 6 are pushed into the second feeding guide rail 6 by the pushing plate 503, and the tennis bracelet accessories are conveyed into the second feeding guide rail 6 one by one, so that the tennis bracelet accessories are changed from being arranged side by side in the first feeding guide rail 401 to being end to end, that is, the rear chain pin is inserted into the front hollow base. The second air cylinder 802 pushes the limiting plate 803 to move, and the limiting plate 803 abuts against the hollow base for fixing. The first linear module 203 drives the ejector rod 202 and the ejector pin 201 to descend, and the ejector pin 201 is inserted into the hollow base to impact the chain pin located in the hollow base so as to bend it and engage it with the hollow base. After the engagement, the tennis bracelet accessories reach the pressing wheel 11. Then, the fourth air cylinder 902 drives the ejecting plate 903 to move upward to bend the bent chain pin again so that the chain pin is bent into two sections, thereby completing the engagement between the tennis bracelet accessories. The ejecting plate 903 presses and limits the chain pin during the bending process by the pressing wheel 11.
