The stopper projection 2212 and the stopper insertion hole 2112 are fitted to each other so that the first connection portion 211 and the second connection portion 221 have only one fitting posture. In a preferred example, the first connection portion 211 may be provided with two limiting insertion holes 2112, the number of the limiting insertion holes 2112 is two, the two limiting insertion holes are located on a side of the circular connection hole 2111 away from the first installation portion 212, and the center of the circular connection hole 2111 is located on a symmetry line of the two limiting insertion holes 2112. And the second connection portion 221 is provided with limit protrusions 2212 which are equal in number and position to the limit insertion holes 2112. Preferably, the limit protrusion 2212 may be provided with a guide surface 2213 for guiding the insertion thereof into the limit insertion hole 2112. Thus, when the two limiting protrusions 2212 are respectively close to the two limiting insertion holes 2112 and ready to be inserted, the guiding surface 2213 can assist the limiting protrusions 2212 to enter the limiting insertion holes 2112, and the situation that the limiting protrusions 2212 cannot enter the limiting insertion holes 2112 due to the inclination of the angle of the limiting protrusions 2212 relative to the limiting insertion holes 2112 is avoided. The guiding surface 2213 may be isosceles trapezoid, or arc, but is not limited thereto. In another preferred example, a limiting protrusion 2212 may be provided on the first connecting portion 211, and the number of the limiting protrusions 2212 is not limited to two, and may be three, four or one. When the number of the restricting protrusion 2212 is one, it is preferable that the restricting protrusion 2212 does not have a cylindrical structure or a truncated cone structure, but is not limited thereto.

The profile formed between the first mounting portion 212 and the second mounting portion 222 is also made structurally stable to enable a more stable connection of the keel profile 4. Since the first connection portion 211 and the first mounting portion 212 are disposed at an angle, and the first connection portion 211, the second connection portion 221 and the second mounting portion 222 are disposed in parallel, an included angle between the first mounting portion 212 and the second mounting portion 222 and an included angle between the first connection portion 211 and the first mounting portion 212 are complementary angles.

Further, the keel section 4 may be provided with at least two coupling portions 41 extending to both ends thereof along the length direction thereof. At least two combining parts 41 can be divided into at least one group, and each group comprises two combining parts 41. The two combining parts 41 are respectively arranged on two opposite corners of the keel section 4. And each of the combining portions 41 extends toward the axial direction of the keel section 4 to form a connecting groove structure. And one end of the first mounting portion 212 departing from the first connecting portion 211 is bent toward the second mounting portion 222 to form a first fastener 2121. One end of the second mounting portion 222 away from the second connecting portion 221 is bent toward the first mounting portion 212 to form a second fastener 2221.

Correspondingly, the bending angles of the first fastening part 2121 and the second fastening part 2221 are also 45 degrees. The first fastener 2121 is used for fastening a connecting groove structure located in the same group, specifically, the first mounting portion 212 abuts against a tube edge 42, and the first fastener 2121 can fasten an inner wall of the connecting groove structure connected with the tube edge 42. Correspondingly, the second mounting portion 222 abuts against another adjacent tube side 42, and the second fastener 2221 can be fastened to an inner wall of the same group of another connecting groove structure connected to the adjacent tube side 42. In this way, the keel profile 4 can be firmly connected to the connecting means 2. Before the keel section 4 is installed on the connecting mechanism 2, the screw 312 of the bolt 31 is inserted into the circular connecting hole 2111, the elliptical connecting hole 2211 and the guide rail 11, and then the nut 32 can be loosened, at this time, the first fixing member 21 and the second fixing member 22 are in a movable state of loose connection, and the limiting insertion hole 2112 and the limiting protrusion 2212 are in a separated state. At this time, the screw 312 drives the first fixing member 21 to move properly in the oval connecting hole 2211, so that the first mounting portion 212 and the second mounting portion 222 can be adjusted slightly, so that the keel section 4 can be smoothly mounted on the first mounting portion 212 and the second mounting portion 222. After the keel section 4 is installed in the first installation part 212 and the second installation part 222, the connecting mechanism 2 drives the keel section 4 to slide along the guide rail 11, and meanwhile, the screw 312 rotates to adjust the position and the inclination angle of the keel section 4. After the adjustment is completed, the nut 32 is screwed, and when the limit protrusion 2212 and the limit insertion hole 2112 are inserted and fitted, the first connecting portion 211 and the second connecting portion 221 and the first mounting portion 212 and the second mounting portion 222 are allowed to have unique assembling postures, so that the keel section 4 can be stably connected to the first mounting portion 212 and the second mounting portion 222.
