Un support de retournement est monté sur une partie supérieure du cadre de support et un cylindre pneumatique est monté au niveau d'une partie supérieure de l'autre extrémité du cadre fixe. Un corps de cylindre du cylindre pneumatique est articulé sur une surface supérieure du cadre fixe. Un siège de poussée est monté au milieu du cadre fixe par ajustement coulissant. Une extrémité de sortie du vérin pneumatique est reliée au siège de poussée et une direction de déplacement de l'extrémité de sortie du vérin pneumatique est une direction linéaire horizontale. Une extrémité du support de retournement est articulée sur le cadre de support et un ensemble roue de guidage mis en correspondance avec un bord latéral de la plaque coulissante est monté sur un côté supérieur de l'autre extrémité du support de retournement. Le support de retournement sous l'ensemble roue de guidage est en ajustement coulissant avec une surface supérieure du siège de poussée. Lorsque le siège de poussée coulisse sous l'entraînement du vérin pneumatique, le support de retournement est entraîné pour tourner vers le haut de telle sorte que l'ensemble roue de guidage correspond au bord latéral de la plaque coulissante. Par conséquent, l'amplitude d'oscillation d'une structure de guidage est réduite, tandis que l'action de guidage du mécanisme rotatif pendant l'utilisation est stable et une structure d'adaptation de la structure de guidage et de la plaque coulissante est précise et contrôlable.
