[0022] Furthermore, the upper ends of the first arc-shaped plates 3 are fixedly mounted with plug rods 8, the two groups of plug rods 8 are fixedly connected by a connecting plate 9, and the lower side of the electric telescopic rod 11 is fixedly connected to the middle of the connecting plate 9, such as Figure 3 As shown, the electric telescopic rod 11 is provided to simultaneously control the two groups of insertion rods 8 to move downward, and simultaneously control the two groups of first arc-shaped plates 3 to move downward.

[0023] Furthermore, the driving assembly includes a second rotating wheel 13, a first motor 15 and a second arc-shaped plate 16. Three groups of second rotating wheels 13 are rotatably installed in an array at the lower end of the second fixed seat 12. A placement groove 14 is provided inside the lower end of the second fixed seat 12. A first motor 15 is provided inside the placement groove 14. The first motor 15 is used to drive the middle second rotating wheel 13 to rotate. A second arc-shaped plate 16 is provided at the upper end of the second fixed seat 12. Three groups of third rotating wheels 17 are rotatably installed in an array inside the second arc-shaped plate 16. A second motor 18 is provided inside the second arc-shaped plate 16. The second motor 18 is used to drive the middle third rotating wheel 17 to rotate. The second rotating wheel 13 and the third rotating wheel 17 rotate in opposite directions. The height of the middle second rotating wheel 13 is consistent with the height of the inner bottom side of the two groups of first fixed seats 2, as shown in FIG. Figure 5 As shown, the pipe inserted into the second fixing seat 12 can be transported to the right side through the setting of the driving assembly.

[0024] Furthermore, the front and rear ends of the two sets of second fixed seats 12 are both provided with limit rods 19, the front and rear sides of the second arc-shaped plate 16 are both fixedly installed with limit plates 20, and the opposite sides of the two sets of limit plates 20 slide on the limit rods 19, such as Figure 5 As shown, this arrangement ensures that the screw rod 22 will not rotate with the second arc-shaped plate 16 when rotating.

[0025] Furthermore, the upper sides of the two sets of second fixing seats 12 are provided with thread grooves 21, the internal threads of the thread grooves 21 are provided with screw rods 22, and the upper side of the second arc-shaped plate 16 is provided with rotation grooves 23, and the lower side of the screw rods 22 rotates inside the rotation grooves 23, as shown in FIG.

[0026] Furthermore, the outer walls of the first rotating wheel 4, the second rotating wheel 13 and the third rotating wheel 17 are all provided with rubber sleeves 5, such as Figure 4 and Figure 5 As shown, this arrangement facilitates increasing the friction with the pipeline.

[0027] Working principle: When the device is used, the staff inserts the pipe to be connected into the middle of the first fixed seat 2. The setting of the three groups of first rotating wheels 4 on the lower side makes it convenient for the staff to push the pipe to the left, and can reduce the friction between the pipe and the middle of the first fixed seat 2. The staff inserts the pipe into the middle of the two groups of first fixed seats 2, and then the staff starts the electric lifting and retracting rod 11. The electric lifting and retracting rod 11 drives the two groups of insertion rods 8 to move downward at the same time, and drives the four groups of first curved plates 3 to move downward at the same time. The two groups of first curved plates 3 on the lower side enter the middle of the slot 7, so that the lower side of the pipe fits against the inner lower side of the first fixed seat 2, and the upper first curved plate 3 moves downward, so that the three groups of first rotating wheels 4 on the upper side fit against On the upper side of the pipeline, multiple groups of rubber sleeves 5 are set to ensure that the position of the pipeline is fixed. Then the staff inserts another group of pipelines into the middle of the two groups of second fixing seats 12. The staff grasps the two groups of screws 22 and rotates them clockwise. The two groups of screws 22 drive the two groups of second arc plates 16 to move downward, and make the three groups of third rotating wheels 17 stick to the upper side of the second group of pipelines at the same time. Then the staff starts the first motor 15 and the screw 22 at the same time. The first motor 15 drives the second rotating wheel 13 to rotate clockwise, and the second motor 18 drives the third rotating wheel 17 to rotate counterclockwise, so that the pipeline can be driven to translate to the right. The staff can then dock the opposite sides of the two groups of pipelines. The above is the entire working principle of the utility model.
