Such terms are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0020] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0021] like Figure 1 to Figure 3As shown, the nylon block for making aviation power transmission copper bars proposed in this embodiment includes an upper part 1 and a lower part 2; the bottom of the lower part 2 is in contact with the ground, and a plurality of semicircular grooves are opened on the top; the bottom of the upper part 1 is opened with a plurality of semicircular grooves corresponding to the semicircular grooves of the lower part 2.
