as shown in fig. 1 and 2, when in use, a long material, such as a tube, is placed on the material supporting arm 622 of the material supporting frame 62, and the tube is supported by the material supporting arms 622 together, so that balance can be maintained; the driving motor 67 operates to drive the slide block 63 to move upwards, and simultaneously drive the horizontal rod 68 to synchronously move upwards, so as to drive the material on the material supporting frame 62 to move upwards;

as shown in fig. 3, when the roller 651 ascends to a certain height along with the horizontal bar 68, the roller 651 is blocked by the blocking guide block 66 and cannot move further upward; at the moment, the horizontal rod 68 continues to move upwards, the roller 651 horizontally moves along the blocking guide block 66, the crank arm 65 rotates to drive the horizontal rod 68 to rotate, and then the three material supporting frames 62 are driven to synchronously rotate for a certain angle;

as shown in fig. 4, the horizontal rod 68 continues to move upwards, the crank arm 65 continues to rotate, and then the material supporting frame 62 is driven to rotate continuously;

as shown in fig. 5, when the horizontal rod 68 rises to a certain height, the roller 651 is pulled to move horizontally in the opposite direction, the crank arm 65 continues to rotate, and then the material holder 62 is driven to rotate continuously; when the horizontal rod 68 moves to the top dead center, the material supporting frame 62 is turned to the final position, at this time, the material supporting arm 622 is higher than the hanging arm 621, and at this time, the pipe rolls down along the discharging guide slope 641 under the action of self gravity, so that the pipe is turned over from one side of the support to the other side of the support.
