[0025] The clamping assembly includes a mounting plate 2, the bottom of which is fixedly connected to the right side of the upper surface of the workbench 1, and a fixing plate 3 is welded symmetrically on the upper surface of the mounting plate 2. A U-shaped limiting hole 4 is provided in the middle position of the top of the fixing plate 3. There are two fixing plates 3 and two U-shaped limiting holes 4. The two U-shaped limiting holes 4 can limit the female connector 16 and the composite pipe body 18. First support plates 5 are welded to the opposite surfaces of the two fixing plates 3. There are two first support plates 5. The two first support plates 5 are symmetrically distributed on the front and back sides between the two fixing plates 3. The two first support plates 5 are fixedly connected to the first electric telescopic devices 6. There are two first electric telescopic devices 6. The output ends of the two first electric telescopic devices 6 are fixedly connected to the first telescopic rods 7, and the opposite ends of the two first telescopic rods 7 are fixedly connected to the C-shaped clamping plates 8; when the two first electric telescopic devices 6 are opened, the two C-shaped clamping plates 8 can be driven by the first telescopic rod 7 to move toward or in the opposite direction, thereby clamping the female connector 16;

[0026] The extrusion assembly includes a second support plate 9, the bottom end of the second support plate 9 is fixedly connected to the left side of the upper surface of the workbench 1, and the left side wall of the second support plate 9 is fixedly connected to the second electric telescopic device 10, and the output end of the second electric telescopic device 10 is fixedly connected to the second telescopic rod 11, the right end of the second telescopic rod 11 passes through the second support plate 9, and the right end of the second telescopic rod 11 is fixedly connected to the extrusion head 12; when the second electric telescopic device 10 is opened, the extrusion head 12 can be driven to move left and right by the second telescopic rod 11. When installing the male connector 14, the staff can first put one end of the male connector 14 on the extrusion head 12, and then open the second electric telescopic device 10 to control the extrusion head 12 to move right, so that the other end of the male connector 14 is tightly inserted into the composite pipe body 18. At this time, the composite pipe body 18 is clamped by the male connector 14 and the female connector 16 to achieve the effect of installing the joint. The operation is simple and convenient, which not only reduces the dependence on the operating experience of the staff, but also helps to improve the efficiency of joint installation.

[0029] Working principle: The staff first places the female connector 16 in the U-shaped limiting hole 4, and then opens the two first electric telescopic devices 6. When the two first electric telescopic devices 6 work, the first telescopic rod 7 can drive the two C-shaped clamps 8 to move toward each other, so as to clamp the female connector 16. Then the staff passes the composite pipe body 18 through the female connector 16, and then puts one end of the male connector 14 on the extrusion head 12, and then opens the second electric telescopic device 10. When the second electric telescopic device 10 works, the second telescopic rod 11 can drive the extrusion head 12 to move to the right, so as to clamp the male connector 14. One end of the joint 14 with the annular raised strip 15 is tightly inserted into the composite pipe body 18. At this time, the composite pipe body 18 is clamped by the male joint 14 and the female joint 16 to achieve the effect of installing the joint. The operation is simple and convenient, which not only reduces the dependence on the operating experience of the staff, but also helps to improve the efficiency of joint installation. Under the action of multiple annular raised strips 15 and multiple annular grooves 17, the contact area between the composite pipe body 18 and the male joint 14 and the female joint 16 can be effectively increased, thereby increasing the clamping strength of the composite pipe body 18 by the male joint 14 and the female joint 16, thereby improving the joint installation quality.
