The root of the outer sidewall of the second protrusion 13 has a second through hole 15, the axis of which is the intersection line between the end face of the track body 11 and the outer sidewall of the second protrusion 13.

[0030] Multiple unit tracks 10 are connected end to end in sequence. The second protrusion 13 of the next unit track 10 is inserted into the concave groove of the previous unit track 10 to realize the splicing of several unit tracks 10.

[0031] See Figure 2 and Figure 3 The first protrusion 12 and the second protrusion 13 are processed in one step as follows: First, prepare a flat and long steel plate, and cut two first through holes 14 and two second through holes 15 on the steel plate; Second, starting from the center of one of the second through holes 15, cut through to one side wall of the steel plate along the width direction, and starting from the center of the other second through hole 15, cut through to the other side wall of the steel plate along the width direction; Third, starting from the center of one of the second through holes 15 and ending at the center of one of the first through holes 14, make a straight cut, starting from the center of the other second through hole 15 and ending at the center of the other first through hole 14; Finally, starting from the center of one of the first through holes 14 and ending at the center of the other first through hole 14, make a straight cut.

[0032] Beneficial effects: Before machining the first protrusion 12 and the second protrusion 13, the first through hole 14 and the second through hole 15 are machined first, and then the first protrusion 12 and the second protrusion 13 are machined.
