Below in conjunction with accompanying drawing, structure and principle of the present utility model are described in further detail.

As shown in Figures 1, 2 and 3, it consists of a turning mechanism 1, a lifting mechanism 2, an adjusting mechanism 3 and a frame 4. The lifting mechanism 2 is located in the middle of the turning mechanism 1 and is fixed on the frame 4. The turning mechanism 1 passes Its guide frame is installed together with the adjustment mechanism 2, wherein:

The turning mechanism 1 adopts a symmetrical structure and is composed of a toothed belt 11, a pulley 12, a synchronous shaft 13, a shaft 14, a clamp 15, a cylinder A16, and a guide frame 17. The toothed belt A111 driven by the cylinder A16 One end is installed on the belt pulley A121 that is fixed on frame 4, and the other end is installed on the end of synchronous rotating shaft 13 by belt pulley B122, and described guide frame 17 above frame 4 is equipped with belt pulley C123, D124, and described synchronous The rotating shaft 13 is slidingly installed with the pulleys C123 and D124. The pulley D124 is connected to the pulley C123 through the toothed belt B112 on the one hand, and connected to the clamp 15 through the rotating shaft 14 on the other hand;

The lifting mechanism 2 is located between the two clamps 15 in the turning mechanism 1, and is composed of a cylinder B21, a guide 22 and a receiving end picker 23. The cylinder B21 is fixedly connected to the frame 4, and the guide 22 can move up and down. Installed on the cylinder B21, the top of the guide 22 is equipped with a receiving end picker 23;
