    所述连接机构包括齿轮57，所述齿轮57转动安装在安装板51上，所述第一滑板54上设置有第一连接板56，所述第一连接板56位于齿轮57顶端，所述第一连接板56与齿轮57啮合连接，所述齿轮57底端啮合连接有第二连接板58，所述第二连接板58固定设置在第二滑板59上，通过夹持气缸53驱动第一滑板54移动，使第一夹持块55朝向第二夹持块510运动，第一滑板54的移动带动第一连接板56移动，通过第一连接板56与齿轮57的啮合、齿轮57与第二连接板58的啮合，第二滑板59随之运动，从而带动第二夹持块510朝向第一夹持块55运动，将管材夹持固定。
    所述提升机构7包括提升气缸71，所述提升气缸71固定安装在固定板3上，所述提升气缸71的伸缩端连接有提升块72，所述提升块72的上端面设置有凹槽73，当管材2落入第三阶梯槽85时，管材正处于提升机构7的上方，通过提升气缸71驱动提升块72上升，将管材运输到加工位置上，凹槽73便于提升块72对管材2的定位，防止在提升过程中管材自由滚动。
