[0002] Excavator, also known as shovel, is the earth-moving machinery that the material above or below the material face is excavated by shovel and is loaded into transport vehicle or is unloaded to stockpile. The material excavated by excavator is mainly soil, coal, sand and soil and rock after pre-loosening. From the development of engineering machinery in recent years, the development of excavator is relatively fast, and excavator has become one of the most important engineering machinery in engineering construction. Excavator bucket tooth is an important part on excavator, similar to human pressure tooth, and is also a wearing part. After damage, it needs to be replaced immediately, otherwise the excavation effect will be affected, such as Figure 1 As shown in the figure, bucket tooth 3 is installed on tooth holder 2 and needs to be fixed by pin, and tooth holder 2 is fixed on excavator bucket 1. When middle bucket tooth 3 is damaged, pin is usually knocked out by hammer and top pin, and new bucket tooth 3 is replaced, and pin needs to be knocked in by hammer again. In the process of using hammer, the adjacent bucket tooth 3 will interfere with the movement track of hammer, and it is difficult to effectively and accurately hammer pin or top pin, and even the pin is hammered skew, which causes the scrap of parts. In view of the above problems, the utility model provides a kind of solution. SUMMARY

DETAILED DESCRIPTION
[0014] The utility model will be further described in detail in combination with the drawings, and the technical scheme in the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection range of the utility model.
[0015] For example, Figure 2 and Figure 3As shown, a tool for mounting a bucket tooth to a bucket seat comprises a tool seat 5, a mounting cavity 6, mounting flaps 7 and a screw rod 8, the mounting cavity 6 is arranged inside the tool seat 5, the tool seat 5 is sleeved outside the tooth seat 2 and the bucket tooth 3 through the mounting cavity 6, the mounting flaps 7 are arranged outside the tool seat 5, the mounting flaps 7 are in L-shaped structure, the mounting flaps 7 are provided with threaded holes, the screw rod 8 is threadedly connected with the threaded holes of the mounting flaps 7, the outer end of the screw rod 8 is provided with a rocker 9, the tool seat 5 is provided with a plug hole 15 coaxial with the threaded hole for the pin 4 to pass through, when the bucket tooth 3 is completely mounted into the mounting cavity 6, the plug hole 15 is coaxially arranged with the mounting hole on the bucket tooth 3.
