The straight light beam emitted by the indicating light beam generator 4 can be irradiated on the corresponding docking hole 2 of the other rocket cabin section 1, so that the two rocket cabin sections 1 are aligned. Then, the two rocket cabin sections 1 are relatively translated to approach each other. When close, the base 3 is detached. Then, the two rocket cabin sections 1 are screwed by bolts. In this way, the docking precision and effectiveness are improved.

[0038] As shown in Figure 1 and Figure 3As shown in the actual application process, the base 3 can be a metal structure or a plastic structure, which is mainly used for installing and positioning the indicating light beam generator 4. In the embodiment, the end face of the base 3 in contact with the rocket cabin section 1 is a plane 7, and the end face of the base 3 away from the plane 7 is provided with a mounting hole 8 in the center; it ensures the stability and levelness of the installation when assembling with the rocket cabin section 1 through the plane 7, avoids tilting, and ensures the levelness or perpendicularity of the light beam. And the level 5 is arranged on the end face of the base 3 away from the plane 7, which is used to detect the levelness of the butt joint position when used vertically; the indicating light beam generator 4 is inserted into the mounting hole 8 for positioning, which is used to emit a light beam to irradiate the mounting hole position of the rocket cabin section 1 to be butt jointed; the positioning connecting piece 6 is fixed at the center position of the plane 7 and is used for connecting and positioning with the rocket cabin section 1. In the embodiment, the positioning connecting piece 6 is mainly used for installing the base 3 on the rocket cabin section 1, and the positioning connecting piece 6 can be a positioning bolt; the plane 7 of the base 3 is provided with a threaded hole 10 in the center; one end of the positioning bolt is threadedly connected with the threaded hole 10 and the other end is threadedly connected in the butt joint hole 2.

In the actual application process, it can also be other positioning connection structures.

[0039] As shown in the actual application process, Figure 1 , Figure 2 and Figure 3 , the end face of the base 3 away from the plane 7 is integrally formed with a boss 9 in the center; the mounting hole 8 is in the center of the boss 9, and the boss 9 is used to increase the insertion contact area of the indicating light beam generator 4.
