[0025] The first driving mechanism 6 includes a rotating ring 10, a toothed ring 11, a rack 12 and a first electric push rod 13.

[0026] The rotating ring 10 is rotatably connected to the bottom surface of the fixed bottom plate 1. The toothed ring 11 is fixedly connected to the outside of the rotating ring 10. The rack 12 is meshed with the toothed ring 11 for transmission. The rack 12 is slidably connected to the bottom surface of the fixed bottom plate 1. The first electric push rod 13 is fixedly connected to the bottom surface of the fixed bottom plate 1 corresponding to the teeth of the rack 12.

[0028] The second driving mechanism 9 includes a second electric push rod 17, a counter groove 18, a top rod 19, a support rod 20 and a spring 21.

[0029] The second electric push rod 17 is fixedly connected to the top surface of the mounting base plate 8, the abutting groove 18 is fixedly connected to the top end of the second electric push rod 17, the bottom end of the ejector rod 19 is fixedly connected to the inner side of the abutting groove 18, the ejector rod 19 slidably penetrates through the bottom of the second forming module 3 and is inserted into the cross groove 4, one end of the support rod 20 is hinged to the side wall of the ejector rod 19, the other end of the support rod 20 is hinged to the third forming module 5, two support rods 20 are arranged in parallel, the spring 21 is sleeved on the outer side of the ejector rod 19 and is located inside the abutting groove 18, the top end of the spring 21 abuts against the bottom surface of the second forming module 3, a stop ring 22 is fixedly connected to the bottom side wall of the second forming module 3, the stop ring 22 abuts against the bottom surface of the fixed base plate 1, and a circular hole for the second forming module 3 to penetrate through is formed in the fixed base plate 1.

[0030] The first electric push rod 13 cooperates with the rack 12 and the gear ring 11 to drive the rotating ring 10 to rotate, thereby driving the convex rod 15 to move through the dislocation movement of the first guide groove 14 and the second guide groove 16, thereby driving the first forming module 2 to move inwards and contract or expand. The second electric push rod 17 drives the ejector rod 19 and the abutting groove 18 to rise, thereby jacking up the second forming module 3 through the spring 21 and inserting it between the expanded first forming modules, forming a stop in cooperation with the stop ring 22, further compressing the spring to make the ejector rod 19 rise, thereby ejecting the third forming module 5 from the cross groove 4 through the support rod 20.

[0032] The working principle of the utility model is:

[0033] During use, the first electric push rod 13 cooperates with the rack 12 and the gear ring 11 to drive the rotating ring 10 to rotate, thereby driving the convex rod 15 to move through the dislocation movement of the first guide groove 14 and the second guide groove 16, thereby driving the first forming module 2 to expand outwards. The second electric push rod 17 drives the ejector rod 19 and the abutting groove 18 to rise, thereby jacking up the second forming module 3 through the spring 21 and inserting it between the expanded first forming modules 2, forming a stop in cooperation with the stop ring 22, further compressing the spring 21 to make the ejector rod 19 rise, thereby ejecting the third forming module 5 from the cross groove 4 through the support rod 20. At this time, the abutting groove 18 abuts against the bottom surface of the second forming module 3 to form a rigid support, thus constituting a complete forming base.

[0034] Meanwhile, reverse operation can be performed. The second electric push rod 17 contracts. At this time, the spring 21 maintains the upward state of the second forming module 3, and the ejector rod 19 drops. Thus, the third forming module 5 is driven by the support rod 20 to contract into the cross groove 4. Further, the second forming module 3 can be continuously pulled out downward, and then the first forming module 2 can be similarly operated to contract inward, so that the overall forming base contracts, facilitating the removal of the fairing.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
