Due to the aforementioned abutment, the cross joint 30 cannot swing or hang down freely, and the freedom of the cross joint 30 is restricted, so that the coupling 3 is in a straight line shape. Therefore, in the interior of the car body in a small space, the coupling 3 whose degree of freedom is limited by the installation tool of this case can be smoothly and conveniently fixed to the afterburner 2 and the gearbox 1.

The above-mentioned degree of freedom, because the first seat 303 and the second seat 304 are pivoted at the cross joint 30, if the first seat 303 and the second seat 304 are not restricted, the first seat 303 and the second seat 304 It will at least rotate 180 degrees or 360 degrees relative to the cross joint 30. Therefore, when the coupling 3 is installed inside the car body in a narrow space, the first seat 303 or the second seat 304 that rotates arbitrarily will work The personnel need extra manpower to fix the direction of the first seat 303 or the second seat 304, but in the small space inside the car body, the extra hand system cannot reach into the car body, so the coupling 3 is installed in the afterburner The difficulty of box 2 and gearbox 1 is undoubtedly increased.

However, the above-mentioned installation tool 4 restricts the direction of the first seat 303 of the cross joint 30. Therefore, when the coupling 3 is installed, no extra human hands are required to reach into the vehicle body.

If the afterburner 2 or the gearbox 1 is to be disassembled from the inside of the car body for replacement or maintenance, the first bolt 301 can be separated from the drive shaft of the afterburner 2 and the gearbox 1, respectively, and the installation tool 4 is installed in the coupling again. For the shaft 3, the head 302 of the first bolt 301 abuts against the first abutment surface 400 of the first abutment post 40 and the second abutment surface 410 of the second abutment post 41, respectively, to restrict the cross joint 3 The degree of freedom, which makes the subsequent fixing of the coupling 3, the afterburner 2 and the gearbox 1 more convenient.
