In the prior art, the iron teeth of the rubber crawler are buried inside the rubber crawler and are mostly of an integral structure, making it difficult to deal with various types of rubber crawlers. Therefore, it is very important to design a rubber crawler iron tooth with a partial replacement structure. For example:

[0003] A rubber crawler iron tooth with the Chinese patent authorization publication number CN209566996U, which relates to the field of crawlers. The key points of its technical solution are: including a cross bridge, a left wing part and a right wing part respectively arranged at both ends of the cross bridge. A left support block protruding from the front of the cross bridge is arranged between the cross bridge and the left wing part, and a right support block protruding from the front of the cross bridge is arranged between the cross bridge and the right wing part. A positioning block protrudes from the back of the cross bridge, and a plurality of anti-slip convex columns are arranged at one end of the positioning block away from the cross bridge.
