[0041] Working principle of the present invention:

[0042] Refer to the instruction manual Figure 1-8First, the user can input gas into the first air inlet 31, and the gas enters the first air guide groove 24 through the first air inlet 31, and then enters the valve groove 26 through the second air guide groove 25, thereby squeezing the piston block 5 to slide upward, and then squeezing the gas above the piston block 5 to be output through the second air inlet 32, and the piston block 5 drives the piston rod 6 to move upward, and then pulls the articulated transmission head to move upward, and the articulated transmission head drives the main rotating rod 13 to rotate. Since the main rotating rod 13 is parallel to the auxiliary rotating rod 14, and the first rod is parallel to the sliding rod 12, a parallelogram is formed between the main rotating rod 13, the auxiliary rotating rod 14, the first rod and the sliding rod 12. Therefore, the main rotating rod 13 can drive the auxiliary rotating rod 14 to rotate synchronously. Since the first rod is parallel to the sliding rod 12, The sliding rod 12 slides on the limiting bar 11, and the angle of the limiting bar 11 remains unchanged. Therefore, the angle of the first rod remains unchanged during the rotation process. The first rod is fixedly connected to the second rod, so the angle of the second rod and the clamping block 16 is also fixedly connected, so that it is convenient to clamp the material accurately and prevent the material from slipping during the clamping process. Then the user can start the servo motor 17 to drive the gear 18 to rotate, and the gear 18 drives the gear sleeve 8 to move up and down through the rack. Since the gear sleeve 8 is fixedly connected to the fixed guide rod 7, and the fixed guide rod 7 is fixedly connected to the cylinder body 2, it can drive the cylinder body 2 to move up and down inside the limiting plate 33. The limiting plate 33 can enhance the stability of the cylinder body 2. At the same time, the fixed guide rod 7 drives the clamping fixture 10 to move up and down, thereby lifting the clamped material;

[0043] Refer to the instruction manual Figure 1-6 Next, the user can input gas into the second air inlet 32 ​​and open the first air inlet 31 at the same time. The gas enters the first fixed block 4 through the second air inlet 32, thereby pushing the piston block 5 down. The piston block 5 squeezes the gas below and discharges it through the first air inlet 31, thereby driving the piston rod 6 to descend, and then loosening the clamped material. A sealing ring 30 is arranged between the cylinder body 2 and the cylinder head 3, and a sealing ring 21 is arranged between the first fixed block 4 and the second fixed block 19, which can enhance the sealing performance of the device, and a wear-resistant ring 23 and a sealing member are arranged on the outside of the piston block 5, which can not only enhance the sealing performance of the piston block 5, but also extend the service life of the piston block 5. When the piston block 5 moves, it can drive the sliding rod 12 to slide inside the limit bar 11, which can limit the piston block 5 and prevent the piston block 5 from rotating, resulting in an angular deviation of the clamping mechanism.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
